Withholding Periods – Winter Pulses
8
• Harvest: DO NOT harvest for 28 DAYS after application.
• Grazing: DO NOT graze or cut for stock food for 21 DAYS after
application
• Export: DO NOT slaughter animals destined for export within 7
days of consumption of treated Chickpea or Lentil crops.
Livestock that have been grazed on or fed treated crops should
be placed on clean feed for 7 days prior to slaughter.
• Ground Application: Apply in a water volume of between 50 and 100 L/ha using a medium quality spray. Use the higher water volume in crops with heavier canopies.
• Aerial Application: Apply with suitable aircraft, set up and operated to apply fungicides to cereal crops in a minimum water volume of 10 L/ha

Ascochyta
• Major disease limiting chickpea production worldwide
• Yield loss can be up to 100%
• Integrated disease management approach is crucial
12
Ascochyta
• Biology – Ascomycetes
• Early infection from seed infection or ascospores (sexual) overwintering in stubble from surrounding areas (5–10 deg C development with long incubation)
• Local infection from conidia (asexual) in stubble and surrounding foliage generally accelerated spread by rainfall.
• Once contact on foliage, germination is within 12 h and visual symptoms within 4 days therefore too late for protectant fungicides. Kovachevski, I.C., 1936. The blight of chickpea (Cicer aritinum). Mycosphaerella rabiei f.sp. Cicri.
Ministry of Agriculture and National Domains, Plant Protection Institute, Sofia, Bulgaria.

Ascochyta
• Integrated Disease Management
• Crop Rotation/Paddock Selection
• Incorporation/ Breakdown of stubble
• Resistant Cultivars
• Clean seed/Seed Treatments
• Nutrition (molybdenum has been
noted to lower ascochyta incidence)
• Weather Observations
• Fungicides

Timing
• Apply first fungicide prior to flowering (4-6 weeks after sowing)
• Prior to visual symptoms (preventativeapproach)
• Spray systemic + protectant fungicides like Veritas® prior to major rainfall (10 mm) events to prevent infection within first 12 hours
Grey Mould (Botrytis cinerea) Life Cycle
15
• Disease inoculum survives on multiple pulse hosts i.e. faba bean, lentils and
chickpeas.
• Can survive on stubble (lentil, chickpea or faba bean), in the soil as sclerotia
and can also be carried on infected seed.
• When seed infected by these fungi are sown seedling blight will occur soon
after crop emergence, reducing plant populations.
• Masses of spores are produced on infected plants then can spread onto
surrounding plants by wind and rain splash to begin new infections.
• Moisture is essential for infection. Lentil crops sown early and/or at high
seeding rates appear to be the worst affected by BGM.
• In order of appearance (can all be present at once)
• Cercospora (mainly Beans) – Dark brown/red circular lesions- Distinct margin expand irregularly
• Ascochyta blight – Dark leaf spots become grey with age and elongate- pale centres may have tiny black fruiting bodies.
• Chocolate Spot (15-25C)Initially pin head spots on one side of leaf.Can turn plant black in notControlled
Registration in Faba Beans being worked on

Early infection from seed
infection or ascospores (sexual)
overwintering in stubble from
surrounding areas (5–10 deg C
development with long
incubation)
Local infection from conidia
(asexual) in stubble and
surrounding foliage generally
accelerated spread by rainfall.
Once contact on foliage,
germination is within 12 h and
visual symptoms within 4 days
therefore too late for protectant
fungicides.
