Contingency measure:
- Irrigated crops - Water management-Based on the crop stage and weather prevail in the local, Irrigation may be given.
- Rainfed and Irrigated crops- All the stage -Decrease in Temperature, increase in Relative humidity compared to last week favour for disease incidence. Spraying of fungicide is must. Intercultural operation Mulching is recommended to increase infiltration, decreased runoff and greater soil water availability.
- Pulses -Flowering to pod development stage- High Relative humidity with dew favours powdery mildew incidence. To control spray Carbendazim 500 g or wettable sulphur 1500g/ha or Propiconazole 500 ml/ha at initiation of the disease and 10 days later. High humidity favours leaf spot disease development. Spray Carbendazim 500 g/ha or Mancozeb 1000g /ha at initiation of the disease and 10 days later. Prevail weather favours pod borer incidence. To control spray Chlorantraniliprole 18.5% SC 100ml/ha.
- Cotton - Square to flowering stage - Prevail weather favours Aphid infestation. Acetamiprid 20% SP 50 g/ha (or) Azadirachtin 0.03% EC 500 ml/ha. Prevailed weather is conducive for stem weevil. So farmers are advised to apply of Neem cake @ 250 kg/ha (or) drenching collar region with chloropyriphos 50EC @1200ml/ha. Secondary infestation of stem weevil, wilt appears. To control spot drench with 0.05 % Benomyl or 0.1 % Carbendazim.
- Paddy- Tillering stage- Prevailed weather is conducive for Leaf folder and Stem borer. So farmers are advised to spray Azadirachtin 0.03% 1000ml/ha. (or) Chlorontriniprole 18.5%SC @ 150g/ha. (or) Thiamethoxam 25% WG @ 100g/ha. Nursery-Prevailed weather is conducive for Rice case worm. To control Dislodge the cases by passing a rope and drain water. Collect the cases and destroy. Spray Quinalphos 25 EC 80 ml
- Sorghum- Vegetative to harvest stage-Cool moist weather with free water on leaf, low night temperature favoursleaf blight. To control spray mancozeb 2g/ litre.
- Chilli - Vegetative to flowering stage- Increasing day temperature favours thrips. Spray Imidacloprid 17.8 % SL @3.0 ml/10 lit.
- Coconut - All the stage -High wind speed may damage the crop; Drainage and earthing up may be practiced to avoid lodging.
