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.
