MangoDiseases
Powdery Mildew (Oidium mangiferae) :Powdery mildew is one of the most serious diseases of mango affecting almost all the varieties. The
characteristic symptom of the disease is the white superficial powdery fungal growth on leaves, stalk of
panicles, flowers and young fruits. The affected flowers and fruits drop pre-maturely reducing the crop
load considerably or might even prevent the fruit set. Rains or mists accompanied by cooler nights
during flowering are congenial for the disease spread.
Control : Alternate spraying of Wettable sulphur 0.2 per cent (2 g Sulfex/litre), Tridemorph O.1 per cent
(1 ml Calixin/litre) and Bavistin @ 0.1 % at 15 days interval are recommended for effective control of
the disease. The first spray is to be given at panicle emergence stage.
Anthracnose (Colletotrichum gloeosporioides) :It is of widespread occurrence in the field and in storage. The disease causes
serious losses to young shoots, flowers and fruits under favorable climatic
conditions (high humidity, frequent rains and the temperature range of 24-
32°C). The disease produces leaf spot, blossom blight, withered tip, twig blight
and fruit rot symptoms. Tender shoots and foliage are easily affected which
ultimately cause die back of young branches. Older twigs may also be infected
through wounds, which in severe cases may be fatal. Black spots develop on
panicles. Severe infection destroys the entire inflorescence resulting in failure
of fruit setting. Young infected fruits develop black spots, shrivel and drop off.
Fruits infected at mature stage carry the fungus into storage and cause
considerable loss during storage, transit and marketing.
Control : The diseased twigs should be pruned and burnt along with fallen leaves. Spraying twice with
Carbendazirn (Bavistin 0.1%) at 15 days interval during flowering controls blossom infection. Spraying
of copper fungicides (0.3%) is recommended for the control of foliar infection.
Postharvest disease of mango caused by anthracnose could be controlled by dip treatment of fruits in 0
Carbendazim (0.1%) in hot water at 52 C for 15 minutes.
Die Back (Botryodiplodia (Lasiodiplodia) theobromae) :Die back is one of the serious diseases of mango. The disease on the tree may be noticed at any time
of the year but it is most conspicuous during October-November. The disease is characterized by
drying of twigs and branches followed by complete defoliation, which gives the tree an appearance of
scorching by fire. Initially it is evident by discoloration and darkening of the bark. The dark area
advances and extends outward along the veins of leaves. The affected leaf turns brown and its
margins roll upwards. At this stage, the twig or branch dies, shrivels and leaf falls. This may be
accompanied by exudation of yellowish brown gum.
Control : Pruning of the diseased twigs 2-3 inches below the affected portion and spraying Copper
Oxychloride (0.3%) on infected trees controls the disease. The cut ends of the pruned twigs are pasted
with Copper Oxychloride (0.3%).
Phoma Blight (Phoma glomerata) : The symptoms of the disease are observed only on old leaves. Initially, the lesions are angular, minute,
irregular, yellow to light brown, scattered over leaf lamina. As the lesions enlarge, their colour changes
from brown to cinnamon and they become almost irregular. In case of severe infection such spots
coalesce forming patches resulting in complete withering and defoliation of infected leaves.
Control : The disease is controlled by spraying Benomyl (0.2%) just after the appearance of the
disease followed by 0.3% Miltox (Copper Oxychloride + Zineb) at 20 day interval.
(e) Bacterial Canker (Xanthomonas campestris pv. mangiferaeindicae) : Canker is a serious disease in India. The disease causes fruit drop (10-70%), yield loss (10-85%) and
storage rot (5-100%). Many commercial cultivars of mango including Langra, Dashehari, Arnrapali,
Mallika and Totapuri are susceptible to this disease. The disease is found on leaves, petioles, twigs,
branches and fruits. The disease first appears as minute water soaked irregular lesions on any part of
leaf or leaf lamina. Several lesions coalesce to form irregular necrotic cankerous patches. In severe
infections the leaves turn yellow and drop off. Cankerous lesions also appear on petioles, twigs and
young fruits. The water soaked lesions also develop on fruits which later turn dark brown to black. They
often burst open, releasing highly contagious gummy ooze containing bacterial cells.
Control : Three sprays of Streptocycline (0.01%) or Agrimycin-100 (0.01%) after first visual symptom
at 10 day intervals and monthly sprays of Carbendazim (Bavistin 0.1%) or Copper Oxychloride (0.3%)
are effective in controlling the disease.
Red Rust (Cepbaleuros virescens) :The disease attack causes reduction in photosynthetic activity and defoliation of leaves thereby
reducing the vitality of the host plant. The disease is evident by the rusty red spots mainly on leaves and
sometimes on petioles and bark of young twigs. . The spots are greenish grey in colour and velvety in
texture. Later, they turn reddish brown. The circular and slightly elevated spots sometimes coalesce to
form larger and irregular spots. The affected portion of stem cracks. In case of severe infection, the
bark becomes thick, twigs get enlarged but remain stunted and the foliage finally dries up.
Control : Two to three sprays of Copper Oxychloride (0.3%) is effective in controlling the disease.
Sooty Mould (Meliola mangiferae) : The disease is common in the orchards where mealy bug, scale insects and hoppers are not controlled
efficiently. The disease in the field is recognized by the presence of a black sooty mould on the leaf
surface. In severe cases, the trees turn completely black due to the presence of mould over the entire
surface of twigs and leaves. The severity of infection depends on the honey dew secretion of the above
insects. Honey dews secretions from insects stick to the leaf surface and provide necessary medium
for fungal growth. Although the fungus causes no direct damage, the photosynthetic activity of the leaf
is adversely affected.
Control : Pruning of affected branches and their prompt destruction followed by spraying of Wettasulf
(0.2% )+ Metacid (0.1 %)+ gum acacia (0.3%) helps to control the disease.
Diplodia Stem-end Rot (Lasiodiplodia theobromae) :The fungus enters through mechanically injured areas on the stem or
skin. The fungus grows from the pedicel into a circular black lesion
around the pedicel.
Control : Careful handling to minimize mechanical injuries.
Postharvest dip of fruits in Carbendazirn (0.1%) in hot water at 52
± 1°C for 15 minutes controls the disease in storage and transit.
MangoDisorders
Spongy Tissue : It is a major problem in Alphonso, where a pulp patch fails to ripen. This malady is caused due to
inactivity of ripening enzymes due to high temperature, convective heat and post harvest exposure to
sunlight.O
Control : Use of mulching and post harvest exposure to low temperatures between 10-15 C for 10-18
hours has been useful in reducing the malady.
Mango Malformation :Malformation is widely prevalent in northern India, particularly in the states of Punjab, Delhi and
western U.P. where more than 50% of the trees suffer from this malady. The malformed panicles
remain unproductive and are characterized by a compact mass of male flowers, greenish in colour and
stunted in growth. The main and secondary rachis is thick and short and bears flowers with relatively
larger bracts, sepals and petals as compared to normal flowers. The malformed panicles remain intact
on the trees for a considerable long period. The complexity of the disorder is attributed to cultural,
nutritional and factors like, mites, fungal, viral, hormonal imbalance etc. The exact cause and control of
the malady is yet to be established.
Control : Spraying of Planofix (200 ppm) during the first week of October followed by deblossoming at
bud burst stage is recommended as a remedial measure against malformation.
Biennial Bearing :The term biennial, alternate or irregular bearing generally signifies the tendency of mango trees to bear
a heavy crop in one year (On year) and very little or no crop in the succeeding year (Off year). Most of
the commercial varieties of north India, namely, Dashehari, Langra and Chausa are biennial bearers,
while south Indian varieties like Totapuri Red Small, Bangalora, and Neelum are known to be regular
bearers. When a tree produces heavy crop in one season, it gets exhausted nutritionally and is unable
to put forth new flush thereby failing to yield in the following season. The problem has been attributed to
the causes like genetical, physiological, environmental and nutritional factors.
Control : For overcoming biennial bearing, deblossoming is recommended to reduce the crop load in
the 'On' year so that it is balanced in the 'Off year. Proper maintenance of orchard by way of effective
control of pests and diseases and regular cultural operations may also result in better performance of
the tree every year.
Soil application of Paclobutrazol (PP ) or Cultar @ 4 g/tree in the month of September resulted in 333
early flowering with higher fruit set and yield. It may be applied every year for regular fruiting,
particularly in young trees.
Ringing of branches is recommended as means of inducing flowering in the 'Off' year. However, Weak,
stunted, unhealthy trees should not be ringed to force flowering. It involves removal of 1 cm wide ring of
bark on a branch of about 15 cm thickness. Ringing stops vegetative growth and results in
accumulation of carbohydrates and other metabolites in the portion of the branch above the ring,
thereby creating physiological condition for flowering. Ringing should be done in August or early
September, well before the time of fruit-bud differentiation.
Fruit Drop : The intensity of fruit drop varies from variety to variety. Among the commercially grown varieties,
Langra is more susceptible to drop, while Dasheri is the least. The fruit drop is more or less a
continuous process and can be classified into three phases, viz. (i) pinhead drop, (ii) post-setting drop
and (iii) May-month drop. The fruit drop in first two phases are insignificant compared to the third phase
which affects the final yield significantly and needs more attention. Embryo abortion, climatic factors,
disturbed water relation, lack of nutrition, attack of disease and pest and hormonal imbalances are the
major factors that lead to fruit drop.
Control : The foliar application of Alar (B-nine) @ 100 ppm or NAA 20 ppm at pea stage of fruit was
found effective in controlling fruit drop in mango.
Black Tip : Black tip is a serious disorder, particularly in the cultivar Dasheri. The affected fruits become
unmarketable and reduce the yield to a considerable extent. The damage to the fruit gets initiated right
at marble stage with a characteristic yellowing of tissues at distal end. Gradually, the colour intensifies
into brown and finally black. At this stage, further growth and development of the fruit is retarded and
black ring at the tip extends towards the upper part of the fruit. Black tip disorder has generally been
detected in orchards located in the vicinity of brick kilns. It has been reported that the gases like carbon
monoxide, sulphur dioxide and ethylene constituting the fumes of brick kiln are known to damage
growing tip of fruits and give rise to the symptoms of black tip. Apart from these factors, irrigation,
condition of the tree and management practices also play important role in deciding the severity of the
disorder.
Control : Planting of mango orchards in North-South direction and 5-6 km away from the brick kilns
may reduce incidence of black tip to a greater extent. The incidence of black tip can also be minimized
by spraying Borax (1%) or other alkaline solutions like caustic soda (0.8%) or washing soda (0.5%).
The first spray of Borax should be done positively at pea stage followed by two more sprays at 15 days
interval.
Clustering in Mango ('Jhumka') :A fruiting disorder, locally known as 'Jhumka', is characterised by the development of fruitlets in
clusters at the tip of panicles. Such fruits cease to grow beyond pea or marble stage and drop down
after a month of fruit set. Absence of sufficient population of pollinators in the orchards is the major
reason. The other reasons causing the disorder are old and overcrowding of trees, indiscriminate
spraying against pests and diseases, use of synthetic pyrethroids, monoculture of Dashehari and bad
weather during flowering.
Control : Introduction of beehives in the orchards during flowering season for increasing the number of
pollinators and restrict insecticidal sprays at full bloom to avoid killing of pollinators.
Pests and diseases should be controlled in time by spraying the recommended pesticides and
concentrations. Spraying of NAA (300 ppm) during October-November is recommended.
The practice of monoculture of a particular variety may be avoided. Particularly in case of Dashehari, 5-
6% of other varieties should be planted in new plantations.
MangoHarvesting
In western India, mango puts forth three growth flushes, the first are in the early spring (February-
March), the second during March-April and the third in the beginning of winter (October-November). In
Bihar, the first growth noticed in early spring, the second in April-May and the third in July-August. In
UP, only two flushes are produced, in March-April and July-August. In Punjab, as many as five flushes
are produced from April-August. April and Mayflushes being found most heavy. In South India, mango
usually gives two growth flushes, one in February-June and the other in October-November. In mango
about 8-10 months old shoots under certain conditions cease to grow at least 4 months prior to
blossoming. These shoots are capable of producing flower buds. Other shoots, which appear in
subsequent flushes during late monsoon, do not come to flowering. These shoots flower during the
next season after accumulating sufficient metabolites necessary for fruit-bud differentiation. Thus the
fruits will be ready for harvest in April-May from a plant flowered during October-November.
The major harvesting seasons in different states are:

The mango fruits should be harvested at green mature stage. In case of Alphonso mangoes the fruit is
considered to be mature when the shoulder outgrow the stem and the external colour becomes light
green with a yellowish red blush. The harvest maturity in Dashehari and Langra cultivars reaches 12
weeks after fruit set, while in Chausa and Mallika it takes about 15 weeks. The best way to observe
maturity in mango is the colour of the pulp, which turns cream to light yellow on maturity and hardening
of stone.
Mangoes are generally harvested at physiologically mature stage and
ripened for optimum quality. Fruits are hand picked or plucked with a
harvester. During harvesting, the latex trickles down the fruit surface from
the point of detachment imparting a shabby appearance to it upon
storage. Therefore the fruits should be harvested with a 10-20cm stem
attached to it. For efficient harvesting of mangoes a simple, low cost and
portable mango harvesting device has been designed and developed at
the Central Institute for subtropical horticulture, Lucknow. Mango fruits are taken into the pouch and
held between the divider and knife and as the device is pulled, the blade cuts the stalk. The fruits are
then conveyed through a nylon chute to collecting boxes without bringing down the device every time.
This saves time and protects fruits from mechanical damage due to impact. It also protects operator's
hand from the sap, which oozes out from the point of detachment. On an average, a man can harvest
about 800 to 1000 fruits per hour with the help of this device, depending on the skill of the worker,
fruiting and height of the tree. It consumes 50 per cent less energy as compared to local methods.
Harvested mangoes should be placed in field containers of not more than 25 kg capacity for movement
to the packing shed. The fruit should be kept in the shade and handled carefully at all times after
harvest.
MangoIntercultural Operations
Training and Pruning :Normally, mango trees do not require frequent pruning. However, the training of the plants in the initial
stages is very essential to give them proper shape. Training becomes very important especially when
the branches are placed at a low level. Therefore at least 75 cm of the main stem should be kept free
from branches and the first leader/main branch is allowed to grow. The main branches should be
spaced in such a way that they grow in different directions and are at least 20-25 cm apart. The
branches, which exhibit tendency of crossing and rubbing each other, should be removed in the pencil
thickness stage. Subsequently pruning is done only to remove the diseased and dead branches.
Weed Control :Immediately after planting the mango, the weed problem may not exist, but it is advisable to break the
crust with hand hoe each time after 10-15 irrigations. However, subsequent hoeing may be done
depending on weed growth in the basin. If the intercrops are not being raised in the pre-bearing stage
due to some reasons, the area between the basins should be ploughed at least three times a year, i.e.,
pre-monsoon, post-monsoon and in the last week of November.
Interculture operations are equally important for the bearing mango orchards. First ploughing should
be done before the onset of rains. This will help in checking run-off losses and facilitate maximum
retention of water in the soil. Orchard may be ploughed again after the rainy season in order to
suppress weed growth and to break capillaries. Third ploughing may be done in the last week of
November or first week of December with a view to check the population of mealy bugs.
The young mango grafts often come to flowering soon after planting or even in the nursery bed. This is
detrimental to their health and vigour, particularly when such flowers are allowed to set fruits. All
inflorescences that may appear during the first four years should be removed immediately after their
emergence.
Intercropping : Mango orchard provides an opportunity for utilizing the land space to its maximum during initial years
of establishment. Crops like green gram, black gram, vegetable crops such as cabbage, cauliflower,
potato, brinjal, cucumber, pumpkin, tinda etc. and spices like chilies can successfully be grown as
intercrops. The partial shade loving crops like pineapple, ginger, turmeric, etc. can be grown in fully-
grown orchards. In addition to field crops, some short duration, less exhaustive and dwarf type inter-
fillers like papaya, guava etc. can also be grown till these do not interfere with the main mango crop.
MangoIrrigation
Amount and frequency of irrigation to be given depends upon the type of soil, prevailing climatic
conditions, especially rainfall and its distribution and age of the trees. No irrigation is required during
the monsoon months unless there are long spells of drought. During the first year when the plants are
very young with shallow root system, they should be watered even at 2-3 days interval in the dry
season. Trees in the age group of 2-5 years should be irrigated at 4-5 days interval. The irrigation
interval could be increased to 10-15 days for 5-8 years old plants during dry season. When trees are in
full bearing stage, generally 2-3 irrigations are given after the fruit set which results in increased fruit-
set, decreased fruit drop, and improvement in fruit size and fruit quality. Frequent irrigation 2-3 months
prior to flowering season should be avoided. It is advisable to irrigate the mango plants in basins
around them to economizing water use. The intercrops need to be irrigated independently as per their
specific requirements.
MangoFertilizer Requirements
Manuring mango plant starts right from planting operation in the orchard. Liberal applications of well-
decomposed organic manure can be given each year to create proper soil physical environment and
on account of several other beneficial effects.

Entire dose of the FYM and half dose of N, P and K should be given during monsoon while the balance
half is applied during the end of monsoon. Before the application of fertilizers, the weeds should be
removed from basins. The mixture of recommended dose of fertilizers should be broadcast under the
canopy of plant leaving about 50 cm from tree trunk in old trees. The applied fertilizer should be
amalgamated well up to the depth of 15 cm. To increase fertilizer use efficiency, fertilizers should be
applied in 25 cm wide and 25-30 cm deep trenches dug around the tree 2 m away from trunk.
The application of micronutrients is not recommended as a routine. Need based supplementation's
are essential when these become limiting factor for production. It is advisable to apply micronutrients
through foliar sprays.
MangoPests
Hopper (Idioscopus clypealis, Idioscopus nitidulus and Amritodus atkinson) :Of all the mango pests, hoppers are considered as the most serious and
widespread pest throughout the country. Large number of nymphs and adult insects
puncture and suck the sap of tender parts, thereby reducing the vigour of the plants.
Heavy puncturing and continuous draining of the sap causes curling and drying of
the infested tissue. They also damage the crop by secreting a sweet sticky
substance which facilitate the development of the fungus Maliola managiferae,
commonly known as sooty mould affecting adversely the photosynthetic activities of
the leaves. Hopper population shoots up in February-April and June-August.
Control : Three sprays of 0.15% Carbaryl or 0.04% Monocrotophos or 0.05% Phosphamidon or 0.05%
Methyl Parathion are effective in controlling the hoppers. First spray should be given at the early stage
of panicle formation. The second spray at full-length stage of panicles but before full bloom and the
third spray after the fruits set at pea size stage are recommended.
Biological control agents such as the predators Mallada boninensis and Chrysopa lacciperda, the egg
parasite Polynema sp. and a preparation of the fungus Beauveria bassiana are important and useful in
controlling this pest.
Mealy Bugs (Drosicha mangiferae) :Nymphs and adults suck the plant sap and reduce the vigour of the plant. Excessive and continuous
draining of plant sap causes wilting and finally drying of infested tissue. They also secrete honey dew, a
sticky substance, which facilitate the development of the fungus Maliola mangiferae (sooty mould).
The female adult crawls down the tree in the month of April-May and enter in the cracks in the soil for
laying eggs. Just after hatching, the minute newly hatched pink to brown coloured nymphs crawl up
the tree. After climbing up the tree, they start sucking the sap of tender plant parts. They are considered
more important because they infest the crop during the flowering season.
Control : Flooding of orchards with water in the month of October kills the eggs. Ploughing the
orchards in the month of November exposes the eggs to suns heat. Polythene bands of 400 gauge and
25 cm width fastened around the tree trunk have been found effective barrier to stop the ascent of
nymphs to the trees. The band should be fastened well in advance before the hatching of eggs, i.e.,
during November- December.
Application of 250 g per tree of Methyl Parathion 2% dust in soil around the trunk kills the newly
hatched nymphs.
Spraying of 0.05% Monocrotophos or 0.2% Carbaryl or 0.05% Methyl Parathion is useful in controlling
young nymphs of the mealy bug. The entomogenous fungus Beauveria bassiana is found to be an effective bioagent in controlling the nymphs of this pest.
Inflorescence Midge (Erosomyia indica) :
The midge infests and damages the crop in three different stages. The first attack is at the floral bud
burst stage. The eggs are laid on newly emerging inflorescence; the larvae tunnel the axis and thus
destroy the inflorescence completely. The mature larvae make small exit holes in the axis of the
inflorescence and slip down into the soil for pupation. When the tender fruits are attacked they slowly
turn yellow and finally drop. The third attack is on tender new leaves encircling the inflorescence. The
most damaging one is the first attack in which the entire inflorescence is destroyed even before
flowering and fruiting. The inflorescence shows stunted growth and its axis bends at the entrance point
of the larvae.
Control : As the larvae pupate in the soil, ploughing of the orchard expose pupating larvae to sun helps
in killing them. Soil application of Heptachlor or Methyl Parathion @ 25 to 30 kg/ha kills pupating
larvae in the soil. Spraying of 0.05% Fenetrothion or 0.045% Dimethoate at the bud burst stage of the
inflorescence is effective.
Fruitfly (Daccus dorsalis;, D. zonatus and D. correctus) : The oriental fruitfly is one of the most serious pests of mango in the country, which
has created problem in the export of fresh fruits. The female punctures the outer
wall of the mature fruits with the help of its pointed ovipositor and insert eggs in
small clusters inside the mesocarp of mature fruits. After hatching, the larva feeds
on the pulp of fruit which appears normal from outside, but drops down finally. The
mature maggots fall down into the soil for pupation. The emergence of fruitfly
starts from April onwards and the maximum population is recorded during May-
July, which coincides with fruit maturity. The population declines slowly from August to September after
that it is non-existent up to March.
Control : Bait sprays of Carbaryl (0.2%)+protein hydrolysate (0.1%) or molasses starting at first week of April
and repeated once after 21 days or hanging traps containing 100 ml water emulsion of Methyl Euginol
(0.1%) + Malathion (0.1%) during fruiting is effective. As per the experiments conducted in IIHR, 0
Bangalore against fruit fly, hot water treatment at 48 C for one hour gave total control in Alphonso and
Totapuri.
Scale Insects : (Pulvinanapolygonata, Aspidiotus destructor, Ceroplastis sp. and
Rastococcus sp) :The nymphs and adult scales suck the sap of the leaves and other tender parts and
reduce the vigour of the plants. They also secrete honeydew, which helps in the
development of sooty mould on leaves and other tender parts of the tree. In case of
severe scale infestation, growth and fruit bearing capacity of the tree is affected
adversely.
Control : Pruning of the heavily infested plant parts and their immediate destruction
followed by two sprays of Monocrotophos (0.04%) or Dimethoate (0.06%) at an
interval of 20 days is very effective in controlling the scale population.
Shoot Borer (Chlumetia transversa) :This pest is found all over the country. Larvae of this moth bore into the young shoot resulting in
dropping of leaves and wilting of shoots. Larvae also bore into the inflorescence stalk. Female moths
lay egg on tender leaves. After hatching, young larvae enter the midrib of leaves and then enter into
young shoots through the growing points by tunneling downwards.
Control : The attacked shoots may be clipped off and destroyed. Spraying of Carbaryl (0.2%) or
Quinalphos (0.5%) or Monocrotophos (0.04%) at fortnightly intervals from the commencement of new
flush gives effective control of the pest. A total of 2 to 3 sprays may be given depending on the intensity
of infestation.
Bark Eating Caterpillar (Indarbella quadrinotata) :The old, shady and neglected orchards are more prone to attack by this pest. Larvae of this moth feed
on the bark and weaken the tree. A single female lays about 300-400 eggs in batches on the bark. The
caterpillar spins brown silken web on the tree, which consists of their excreta and wood particles.
Larvae also make shelter tunnels inside the stem in which they rest. Larvae generally feed from April to
December.
Control : Removal of the webs from tree trunks and injecting emulsion of Monocrotophos (0.05%) or
DDVP (0.05%) in each hole and plugging them with mud can control the pest.
Stem Borer (Batocera rufomaculata) : The grub of this beetle causes damage as it feeds inside the stems, boring upward resulting in drying of
branches and in severe cases attacked stem is killed. Eggs are laid either in the slits of tree trunk or in
the cavities in main branches and stems covered with a viscous fluid. Pupation takes place within the
stem. Beetle emerges in July-August
Control : Cleaning the tunnel with a hard wire, pouring kerosene oil, creosote, petrol, crude oil or
formalin and subsequently closing entrance of the tunnel with mud or plugging it with cotton wool
soaked in any of the above substances kills the grub.
Shoot Gall Psylla (Apsylla cistellata) :It is a very serious pest of mango in many parts of India, particularly in Tarai region of U.P., north Bihar
and West Bengal. This pest creates green conical galls in leaf axis. The activity of the pest starts from
August. The galls dry out after emergence of adults in March. The adult females lay eggs in the midribs
as well as in lateral axis of new leaves. Nymphs emerge from eggs during August-September and
crawl to the adjacent buds to suck cell sap. As a result of feeding, the buds develop into hard conical
green galls. The galls are usually seen during September-October. Consequently, there is no fruit set.
Control : The galls with nymphs inside should be collected and destroyed to prevent carryover of the
pest. The pest can effectively be controlled by spraying of Monocrotophos (0.05%), Parathion
(0.04%), Metasystox (0.1%) or Quinalphos (0.05%) at 2 week intervals starting from the middle of
August. Repeated use of same chemical for every spray should be avoided.
Leaf Webber (Ortbaga euadrusalis) :The infestation starts from the month of April and continues up to December. Eggs are laid singly or in
clusters within silken webbings on leaves. Upon hatching, the caterpillars feed on leaf surface by
scrapping. Later, they make web on tender shoots and leaves together and feed within. Old orchards
with lesser space between tree canopy have more infestation than open orchards.
Control : Pruning of infested shoots and their burning in the month of April to July is found effective.
Raking of the soil around the base of the trees in January, after the last generation has pupated, helps
in checking the pest population. Three sprays starting from the last week of July at 15 days interval with
Carbaryl (0.2%) or Monocrotophos (0.05%) or Quinalphos (0.05%) effectively controls the pest.
Stone Weevil (Sternochetus mangiferae) : It is a common pest of mango in southern India. Varieties with high TSS and sugar such as Alphonso,
Bangalora, Neelum, etc. are more prone to attack by this pest.
Female lay eggs under the rind of ripening fruits. Newly emerged grubs bore through the pulp, feed on
seed coat and later cause damage to cotyledons. Pupation takes place inside the seed. Pulp is
discoloured around the affected portion.
Control : The pest population can be kept under check by destroying the affected fruits and exposing
the hibernating weevils by digging the soil.
Spraying the trees with Fenthion (0.01%) is found effective.
In Alphonso and Banganapalli, a single spray of Monocrotophos 36 EC 1.5ml/litre of water at marble
stage gave 100% and 97.5% control of stone weevil respectively. In Totapuri, Carbaryl 50 % WDP @ 4
g/ litre of water is effective in controlling stone weevil.
MangoPost Harvest Technology
Grading : If the fruits are graded according to their size, weight, colour and maturity, both the producer and
consumer are benefited. It has been observed that bigger size fruits take 2-4 days more time in
ripening than smaller ones. Hence, packaging of smaller fruits with larger ones should be avoided to
achieve uniform ripening. Immature, overripe, damaged and diseased fruits should be discarded.
For exports, the stem of the fruits is cut approximately at a length of 1 cm from the fruit with the help of
sharp scissors. Then the fruits are kept up side down for two hours so that the latex flows out from the
fruit completely. For this operation special knitted pallets should be prepared to keep the fruit up side
down. Utmost care should be taken while cutting the stem of the fruit so that latex drop does not fall on
the fruit.
The export quality mangoes are categorised into three grades according to the fruit weight viz.,
Category-I (200-250 g), Category-II (251-300 g) and Category-III (300-350 g).
Mangoes do not normally need any post-harvest treatment for local marketing. It is a general practice
to harvest fruits early in the season (premature stage) to capture early market. These fruits do not ripe
uniformly without any ripening aid. Such fruits could be ripened uniformly by dipping in 750 ppm
Etherel (1.8 ml/litre) in hot water at 52±2°C for 5 minutes within 4-8 days under ambient conditions.
Mature fruits can similarly be ripened with lower doses of Etherel for uniform colour.
Fruits for urban supermarkets may need to be washed if they are heavily contaminated with latex or
dust. On a commercial scale, mangoes for export are sometimes dipped in hot water containing
fungicide for the control of this disease. The treatment is not appropriate for small-scale operations.
The post harvest losses in mangoes have been estimated in the range of 25-40% from harvesting to
consumption stage. If proper methods of harvesting, transportation and storage are adopted, such
losses could be minimized
Packaging : Usually, fruits are placed in layers one above the other, with a straw padding in-between.
Temperatures between 19-21°C during ripening improve the quality of
fruits.
Wooden boxes are commonly used for packaging and transportation of
mango fruits. Central Institute for Subtropical Horticulture, Lucknow has
designed and developed CFB Boxes of 5 kg and 10 kg capacity for
packing and shipping of mango fruits successfully as an alternative to
traditional nailed wooden boxes. The use of CFB boxes for packaging for
the domestic market is also the need of the hour due to scarcity of the
wood and environmental concerns of the country. For export purposes, CFB boxes are already in
extensive use. Paper scraps, newspapers, etc., are commonly used as cushioning material for the
packaging of fruits which prevent them from getting bruised and spoiled during storage and
transportation. Polythene (LDPE) lining has also been found beneficial as it maintains humidity, which
results in lesser shrinkage during storage. Wrapping of fruits individually (Unipack) with newspaper or
tissue paper and packing in honeycomb nets helps in getting optimum ripening with reduced spoilage.
Storage :Storage is essential for extending the consumption period of fruits, regulating their supply to the market
and also for transportation to long distances. The mature green fruits can be kept at room temperature
for about-4-10 days depending upon the variety.
For exports, the harvested fruits are pre-cooled to 10-12°C and then stored at an appropriate
temperature. The fruits of Dashehari, Mallika and Amrapali should be stored at 12°C, Langra at 14°C
and Chausa at 8°C with 85-90% relative humidity. The fruits could be stored for 3-4 weeks in good
condition at low temperature.
Controlled atmosphere (CO 3-4 % and O 4-5%) storage of Alphonso mango, under a continuous flow 2 2
0system held at 13-15 C indicated that Alphonso could be kept for 30 days with a post storage ripening
period of 4 to 5 days.
Transport :For local market the harvested fruits are packed in wooden boxes/CFB
and transported by trucks.
Cool Chain :Cool chain is essential during the transport of export quality commodity all the way from the farm to the
customer. This helps in maintaining the temperature inside the box at the same low level as in the cold
storage.
The various stages of the cool chain are :1. Coldstore at the farm.
2. Refrigerated truck from farm to the airport
3. Coldstore at the airport.
4. Building up of the pallet in a coldstore at the airport.
5. Loading the aircrafts directly from the coldstore in a short time.
6. Cargo aircraft maintains coldstore temperature in hold.
7. Off loading direct into a coldstore in the receiving country.
Refrigerated truck to the customers.
MangoPlanting
Prior to planting, field should be deeply ploughed, harrowed and levelled. The planting distance varies
according to variety, the fertility level of the soil and general growth conditions in the area. Where the
growth is excessive, the distance should be 12 x 12m, but in the dry zones where the growth is less, it
can be regulated to about 10 x 10m. For high density planting, the distance can be 5 x 3 or 5 x 2.5 or 3 x
2.5 or 2.5 x 2.5m.
In locations where the soil is loamy and deep, pits of 0.5 x 0.5 x 0.5m be dug at desired distances.
However, in shallow and hill soils, the pits should be of 1 x 1 x1 m size. The pits should be filled with the
original soil mixed with 50 kg well rotten FYM. In the top two-third portion, the proportion of the manure
and soil may be kept as 1:3. If the soil is having infestation of white ants, 200-250 g of Aldrex or BHC 5
per cent dust may also be mixed. The pits should invariably be filled before the rainy season, so that
there is maximum settling down before the advent of heavy rainfall.
The best time for planting all over India is during the monsoon season when the humidity level is high.
In the area of heavy rainfall, the best time of planting mango is the end of the rainy season. In tracts
where the rainfall is less, the planting can be done in the early part of the monsoon season for better
establishment. The planting should be done in the evening. If the sky is overcast, planting can be done
during daytime also.
The plant with earth ball intact should be taken out of the polythene bag or pot. The plant can then
be placed in the centre of the pit by excavating as much soil as necessary to accommodate the
earth ball or root ball. The moist soil of the pit is then pressed all around the root ball to complete
the planting process. A small basin is then made and the plant is properly watered. The planting
should not be done so deep as to bury the graft-union in the soil or so high as to expose the upper
roots. It is always better to adjust it at the same height/depth at which it was in the pot/polythene
bag.
MangoPropagation
Mango can be raised from seed or propagated vegetatively.
Several methods of vegetative propagation have been tried with varying degrees of success.
Propagation from seed, though easy and cheap, is unable to perpetuate characters of the parent tree
because most commercial varieties in India are cross-pollinated and monoembryonic. Plants also take
more time to bear fruit. However, it is essential to raise seedlings to be used as rootstocks.
Stone Grafting : Stone/epicotyl grafting is a simple, cheap and quick method of mango propagation with a success rate
of 75-80%. For this purpose, stones should be sown in June-July on raised beds of size 1x3 m. the
beds should e prepared by mixing soil and FYM in the proportion of 2:1. After germination, seedlings
with tender stems having coppery leaves are lifted with stones still attached. The roots and stones are
dipped in O.1 per cent Carbendazirn solution for 5 minutes after washing the soil. The seedling stems
are headed back leaving 6-8 cm long stem. A 4-6 cm longitudinal cut is made running down through the
middle of the stem. A wedge shaped cut starting on both sides is made on the lower part of scion stick.
The scion stick should be 4-5 months old and 10-15 cm long containing plumpy terminal buds. The
scion stick is then inserted in the cleft of the seedlings and tied with polythene strips. The grafts are
then planted in polyethylene bags containing potting mixture. The bags are then kept in the shade
protecting from heavy rain. The scion stars sprouting 15-20 days after grafting. Care should be taken to
remove the sprouts on the rootstocks below the graft union during this period. July is the most suitable
month for stone grafting.
Soft-Wood Grafting :This method of grafting is done when the rootstock is overgrown and thus not suitable for stone
grafting. Normally in this method, seedlings of 8-10 months old are selected. The grafting is done on
newly emerged flush. The scion wood to be used is defoliated 10 days prior to the grafting and has
same thickness as that of terminal shoot. The method of grafting is similar to stone grafting. July and
August are the best months for soft-wood grafting.
Inarching :The method of inarching or approach grafting is quite cumbersome and time consuming, but it is still
the leading method for commercial propagation of mango plants. The method consists of uniting the
selected shoot (scion) of a desired parent tree (mother plant) with the potted or transplanted seedling
(rootstock) by approach grafting. For this purpose, about one-year-old seedlings are most suitable
when they attain a height of about 30-45 cm and thickness ranging from 0.75 to 1.5 cm. These
seedlings are either grown in pots or under the mother plant from which the grafts are to be prepared.
Generally, one-year-old twigs of the scion tree about 60 cm in length and nearly of the same thickness
as that of the stock is chosen for grafting. Young and non-bearing trees should not be selected as
mother plants.
A thin slice of bark and wood, about 5 cm in length, 7.5 mm width and 2 mm deep, is removed by means
of a sharp grafting knife from the stem of the stock as well as from the scion branch. The cuts thus made
should be absolutely flat, clean, boat shaped, even and smooth. The ends of these cuts should be
round and not angular. The cut surfaces of both, i.e., stock and scion are made to coincide facing each
other so that there remains no hollow space between the two. Polythene/alkathene strips of about 1.5
cm in width are tied around the union. After about one month of operation, the scion below the graft
union and stock above the graft union should be given light "V" shape cuts at weekly interval in such a
way that the grafts can finally be detached while giving the fourth cut. In the last stage, the top of the
stock above graft union should also be removed completely.
Inarching should be done during the active growth period. The end of the monsoon in heavy rainfall
areas and early monsoons in the light rainfall areas is the best period for inarching.
Veneer Grafting :This method of propagation possesses promise for mass scale commercial propagation. The method
is simple and can be adopted with success. The rootstocks as mentioned for inarching are suitable for
this method also. For conducting this grafting operation, a downward and inward 30-40 mm long cut is
made in the smooth area of the stock at a height of about 20 cm. At the base of cut, a small shorter cut is
given to intersect the first so as to remove the piece of wood and bark. The scion stick is given a long
slanting cut on one side and a small short cut on the other so as to match the cuts of the stock. The
scion is inserted in the stock so that the cambium layers comes on the longer side. The graft union is
then tied with polythene strip as recommended for inarching. After the scion remains green for more
than 10 days, the rootstock should be clipped in stages.
The scion wood to be used for veneer grafting requires proper preparation. The desired shoots should
be defoliated at least one week prior to grafting so that the dormant buds in the axil of leaves become
swollen.
MangoSoil & Climate
Mango is very well adapted to tropical and subtropical climates. It thrives well in almost all the regions 0 0
of the country from sea level to an altitude of 600 m. The ideal temperature range for mango is 24 -30 C
during the growing season, along with high humidity. A rainfall range of 890-1,015 mm in a year is
considered as ideal for growing mangoes. However, mango can be grown in regions of both heavy
(2540 mm) or scanty (254 mm) rainfall. Dry weather before blossoming is conducive to profuse
flowering. Rain during flowering is detrimental to the crop as it interferes with pollination.
Fog, cloudy weather at the time of flowering from November to February results in poor setting of fruits
and favours pest and disease incidence. Mango grows well on wide variety of soils, such as lateritic,
alluvial, sandy loam and sandy. The loamy, alluvial, well-drained, aerated and deep soils (2-2.5 m) rich
in organic matter with a pH range of 5.5-7.5 are ideal for mango cultivation. The water table should be
around 3 m and soils with high water table are unsuitable for mango.
