Abstract:
Field experiments were conducted to evaluate IPM modules against major insect- pests of soybean at farmer’s field in adopted village of RVSKVV, Krishi Vigyan Kendra, Dewas (M.P.) during kharif season of the year 2015and 2016. These revealed that IPM module M1 ((Deep ploughing and exposure of soil to hot summer to kill pupating larvae, Use of optimum seed rate @75Kg/ha, Seed treatment with Thimethoxam 70WS 3g/kg of seed, Installation of pheromone trap @ 10/ha, for tobacco caterpillar, Erection of bird perches @ 50/ha and Spraying of Chlorantraniliprole 18.5% SC @ 100 ml/ha at ETL level) proved to be most effective with lowest incidence of whitefly, blue beetle, green semilooper, tobacco caterpillar and pod borer and significantly superior module M2 (Deep ploughing and exposure of soil to hot summer to kill pupating larvae, Use of optimum seed rate @75Kg/ha, Seed treatment with Thimethoxam 70WS 3g/kg of seed, Installation of pheromone trap @ 10/ha, for tobacco caterpillar, Erection of bird perches @ 50/ha, Spraying of NSKE @ 800 ml/ha at ETL level and Spraying of Trizophos 40 EC @ 800 ml/ha at ETL level). Whereas IPM module M2 found most effective against girdle beetle, where 4.47% were recorded followed by M3 and at par with M4. The higher seed yield i.e. 1978 and 1612 kg/ha was found in the module M1 during both the years. The studied also showed that net return was also higher and maximum ICBR in module M1 (1:1.66).
