Monitoring for Pest & Disease
- Community level monitoring to know change in destruction and abundance of pest
- Organise regular pest monitoring and assess bio control potential at every 5 to 10 km distance at 12 spots/ha and 5 plants/spot selected randomly.
- Use pheromone traps for monitoring Spodoptera/Helicoverpa and leaf miner.
Pre-Sowing stage
- Deep ploughing in summer.
- Partial or complete lopping of host plants and retaining of preferred host trees in area of white grub adults.
- Crop rotation with sorghum/pearl millet or maize.
- Early sowing.
- Collection and destruction of white grub adults.
- Installation of 12 light traps/ha or bonfire against Red Hairy Caterpillar
Sowing stage
- Two hand hoeing at 20 days and 35-45 days after sowing for effective weed control.
- Stray planting of cowpea or soybean (for leaf miner) castor and sunflower for S. /itura as trap crops.
- Soil application of castor cake @ 1000 kg/ha or neem cake against stem rot.
- Continue with light trap or bonfire against RHC.
- Collection and destruction of egg masses of RHC in the fields around light-trap areas.
- Seed treatment with Carbendazim @ 4g/kg OR Trichoderma viride, T. harzianum @ 4 g/kg seed.
Vegetative stage
- Rouge out bud necrosis affected and chump infected plants.
- Irrigate once.
- Continue with light trap or bonfire and mechanical collection of RHC egg masses/caterpillars.
- Install one pheromone trap per ha. for monitoring or 5 trap/ha for mass trapping of Spodoptera.
- Collection and destruction of- early stage larvae of Bihar hairy cater pillar.
- Collection and destruction of white grub adults from jujube or neem trees around the field.
- Install per ha.10-12 bird perches.
- Two hand or mechanical weeding at 15-20 days after sowing.
- Release egg parasite, Telenomus remus @ 50000/ha, 4 times (7-10 days interval) against Tobacco Caterpillar
- Spray SNPV @ 250LE or B.t @ 1 kg/ha for controlling defoliators.
- Spray Carbendazim @ 375 g a.i./ha or 2 gm of Chlorothalanil/lit for control of leaf spots and rust.
- Spray Endosulfan 35 EC or Quinalphos @ 1250 ml/ha to control hairy caterpillar.
Flowering stage
- Collect and destroy egg masses and early instar larvae of S. litura.
- Continue Pheromone trap @ 1/ha for monitoring or 5/ha for mass trapping of S. litura
- Spray neem based formulation @ 2%.
- Release Trichogramma chilonsis (50000/ha) twice and Cheilomenus sexmaculata (1250/ha twice) against leaf miner and other defoliators.
Fruiting stage
- Collect egg masses and early instar larvae of S. litura.
- Spray neem based formulation @ 2%.
- Spray SNPV @ 250 LE/ha or B.t. 1 kg/ha on need basis.
- No chemical control applied at the maturity stage.
Storage
- Store the pods in polythene lined gunny bags and fill the top of the bags with sand.
- Mouth of bags not be closed to avoid germination loss.
- Harvest at optimum maturity stage to avoid pod infection.
