WHAT IS IPM ?

o An important tool to maintain the pests population those levels causing economic injury .

o Retain also the balance of food chain in agroecology along with reduction of pest population .

o All available as well as possible meanses become integrated here .

o Modern eco-friendly approach to save crops from pests .

ON WHICH LIE ? - MONITORING

Principle of IPM is Monitoring – Field observation at 3 – 4days interval . Those record at 10 – 14days interval from

sowing to mid-tillering & weekly mid-tillering onwards .

As & when required ,observation through either diagonal or zigzag walking .

Walking start from a corner of field and always in the early morning .

25 hills thoroughly observe – 5hills at 5spots .

CONTD.

Farmers should be persuaded for daily field visit and to watch for pests and biocontrol agents .

Observation must be recorded at each 5 - 10km Distance

At least 20 spots must be observed . Sweep nets and water-pans may also be used for

pests and biocontrol agents’ population assesment .

Light trap with 200w. Mercury lamp(2hrs) may also be used .

Pheromone trap - 5traps/Ha may be used .

STRATEGIES OF IPM

Cultural :- Tillage Clean Seed Clean Culture Use of tolerant variety Irrigation Fertilization Crop Spacing Crop Rotation Intercropping Trap Crops Pruning & thining and Training Time of Sowing & Harvesting

CONTD.

Physical :- Hot or Cold teratment

Light/Pheromone Trap

Bird Percher

Moisture

CONTD.

Mechanical :- Hand Picking

Exclusion by Screens and Barries

Trapping and Suction Devices

CONTD.

Biological :- Introduction, Conservation , augmentation and

inundation of natural enemies as follow -

CONTD.

Water Treader ; Water Strider

PARASITE WASP Xanthopimla ; Charops sp.

CONTD.

Chemical :- It may be taken up – Unless former another methods is not taken time

to time . Whereas , in spite of taking formers timely , they

bychance become failure

exceptionally Disease management , because – “Prevention is better than cure”

CONTD.

Concept of injury levels(ETL/EIL) are so important to take up chemical measure -
