  1. Pesticide use in Tomato IPM • Natural enemies are an extremely important component of integrated pest management of tomato insects and mites. • Insecticides are useful component of IPM programs because of their convenience, simplicity, effectiveness, flexibility and economy. • Using selective insecticides to kill the target pest without killing natural enemies helps maximize as well as integrate chemical and biological controls. • Nonselective insecticides, can be made more selective by careful application rates, timings and coverage to minimize killing natural enemies. • Products that have a short residual effect on natural enemies are favored for IPM programs. Consider both the short-term and long-term effects of an application when selecting an insecticide treatment. Next

  2. Nursery preparation • Before sowing, the nursery beds should be drenched with 0.2% Dithane M-45 or treated with Difolaton or captan • Treat nursery belt with carbofuran 3G 100g/sq m for nematode management • Seed Treatment • Treating the seeds with Thiram @ 3g per kg of seeds will prevent the seed born fungal diseases • During summer and rainy season, there is a very heavy incidence of damping off. To protect seeds and seedlings, the beds should be treated with 10% formaldehyde. End Previous Next

  3. Seedling treatment • Before transplanting, seedlings should be treated with insecticides 0.1% nuvacron and Dithane M-45 0.2% • Hardening is done by adding 4000ppm sodium chloride or spraying 2000ppm ccc is effective for hardening of seedlings End Previous Next

  4. Application of bleaching powder @15kg/ha before planting against bacterial wilt infection in endemic areas • Spray 40-100ppm streptocycline sulphate on unripe fruits of tomato to control bacterial spot or dipping the seedlings 100 ppm streptocycline sulphate before transplanting. • Imidacloprid 17.8 SL @25g ai/ha or thiamethoxam 25 WG@ 25g ai/ha or acetamiprid 20 SP@ 20g ai/ha can be used for managing sucking insect pests such as aphids, jassids, leaf hopper and whitefly. End Previous Next

  5. Spraying of Chlorfenapyr 10 SC@100 g ai/ha or Fipronil 5 SC@50 g ai/ha for thrips management • Friut borers such as Helicoverpa armigera and Spodoptera litura can be managed by applying Emamectin benzoate 5 SG@11 g a.i/ha or Spinosad 45 SC@75g a.i/ha or Flubendiamide 480SC@48-60gai/ha • Propargite 570EC @500gai/ha will be helpful in the management of mite population in tomato End Previous Next

  6. Soil drenching of Fytolan @ 4g/l for managing bacterial wilt disease is advocated. • Dithane M- 45 2g/l is recommended for to manage fruit rot of tomato • Application of pendimethylin @1kg ai/ha+1hand weeding 45days after transplanting, or Sensor @205kgai/ha or gol@0.25kgai/ha applied after transplanting are effective to control weeds. End Previous Next
