 Integrated pest management in cotton


  • Summer ploughing and stubble burning.
  • Seed treatment with imidacloprid 70% WS @ 7g/kg of seed
  • Two releases of Trichogramma chilonis @ 1.5 lakh eggs/ha at 55 and 65 DAS
  • Spraying  NSKE 5% at 45 and 100 DAS
  • Spraying Ha NPV @ 500 LE/ha at 60 DAS
  • Spraying chlorpyriphos/quinalphos/profenophos at 90 DAS
  • Spraying synthetic pyrethroid at 120 DAS on need basis.
  • Installation of H.armigera pheromone traps @ 5 number/ha at 60 DAS to monitor bollworm population
  • Installation of bird perches @ 20 number/ha
  • Growing cowpea (1 row after every 10 rows of cotton) as an intercrop and African marigold/castor as border crop to trap the pests like aphid, American bollworm and spotted bollworm.
  • Growing of ecofeast crop like maize to harbour the beneficial predators

Management of wilt complex in solanaceous vegetables


The bacterial and fungal wilt is a serious problem in solanaceous vegetables. It can be managed through :

  • Seed treatment with (Carboxyn 37.5% + Thiram 37.5%) DS @ 1.5 g or carbendazim @ 2 g/kg seed.
  • Seedling root dip treatment with streptocycline (1 g / 10 litre water) for 20-30 minutes.
  • Basal soil drenching with Metalaxyl (0.2%) or carbendazim (0.2%) in case of fungal wilt or with streptocycline (0.015%) or plantomycin (0.15%) mixed with 0. 2% Copper oxychloride.
  • Growing resistant varieties.
