Technology Developed Department of Agriculture Entomology Brsa Agricultural University, Kanke, Ranchi 1. Development of IPM modules in rice crop Gallmidge resistant varieties viz., Lalat, RD-202, BG-380-2, IR-36, Abhay were used. In general Carbofuran 3 G or cartap hydrochloride granules @ 5 gram/ sqm were used in the nursery 5 days before transplanting the rice. Phorate 10 G @ 10 kg/ha or cartap hydrochloride granule @ 25 kg/ha were broadcasted in the field 20 days after transplanting the rice seedlings followed by need based foliar application of Monocrotophos 36 WSC(1.5 litre/ha) at 40 days after transplanting (DAT) alternated with Chlorpyriphos 20 EC @ 2.5 litre /ha at 60 DAT. 2. Development of IPM modules In Maize Seeds are treated with Chlorpyriphos @ 8ml per Kg of seed for half hours in shade before sowing. Trichogramma are used against the maize stem bores is a cost-effective method against this dreaded pest. Trichocards containg the parasitized eggs of Trichogramma chilonis are stapled undersurface of leaf @ 8 cards per hectare at twice (12 and 22days after germination of seeds). 3. Development of IPM modules In Urdbean and Mungbean The developed IPM modules comprises: Seed treatment with imidacloprid ST600 FS 5ml/kg seed + carbendazim 2gm/kg seed fallowed by rhizobium inoculation; Intercrop (4:2) with ragi; mechanical measures i.e. removal of virus infested plants and picking of pod borer, hairy caterpillar and their destruction; Biorational NSKE 5% spray at 30DAS and need based application of insecticide triazophos 0.04%. The application of NSKE 5% is eco-friendly. 4. Holistic IPM packages for chickpea under midland irrigated agro-ecological situation IPM packages adopting various technologies (seed treatment, line sowing, balance used of fertilizers, Spray of NPV Ha, Biorational NSKE 5%, installation of pheromones traps, installation of bird perches and need based application of insecticide)in a sequential manner and evaluated in farmers field under rice- chickpea cropping system. 5. Development of low cost management of shootfy infesting little millet. Seed treatment with insecticide is a cost-effective method against this dreaded pest. Seeds are soaked in Imidacloprid solution@ 0.3ml per litre of water for six hours in shade before sowing. One liter of solution is required for 1 kg of seed. Seeds are then sown in furrows in line and covered with soil.
Recommendations for the management of insect pests of different crops Management of Insect Pests of Rice Seedling root dip of rice in chlorpyriphos solution (0.02%) was found to be highly effective against gall midge and yellow stem borer.
