Abstract

The field experiment was conducted under shade net house at Hi-Tech Horticulture Farm, Rajasthan Agricultural Research Institute, Durgapura (Sri Karan Narendra Agriculture University, Jobner), Jaipur, Rajasthan to investigate the effectiveness of IPM modules on the reduction of yellow mite, thrips, whitefly, aphid and beet armyworm during summer 2014 and 2015 on capsicum (Capsicum annum L). The experiment comprised three IPM modules along with local check replicated seven times under randomized block design. The treatments were imposed at an interval of 20 days, starting from initial notice of pest population up to six treatment spray observation. The results revealed that during 2014 and 2015 all the treatments significantly reduce the population of capsicum pests over untreated control. The findings revealed that Module-II (M-II), chemically intensive module (imidacloprid 17.8 SL (0.0089%) - dimethoate 30 EC (0.051%) - emamectin benzoate 5 SG (0.002%) - fenazaquin 10 EC (0.02%) - dicofol 18.5 EC (0.37%) - acephate 75 SP (0.075%) proved significantly most effective reducing mite (62.38%), thrips (61.48%), whitefly (58.54%), aphid (58.46%) and beet armyworm (46.80%) on the basis of Pooled observation of 1, 3, 7 and 15 days after spray during 2014 and 2015. Module-I (M-I), IIHR based module comprising (profenophos 50 EC (0.1%) - NSKE 5% - emamectin benzoate 5 SG (0.002%) - Verticillium lecanii (0.004%) - fenazaquin 10 EC (0.02%) - profenophos 50 EC (0.1%) showed effective reduction against mite, aphid and beet army worm and least effective against whitefly and thrips. Module-III (M-III), bio-rational module comprising (imidacloprid 17.8 SL (0.0058%) - azadirachtin 0.15 EC (0.0003%) - emamectin benzoate 5 SG (0.002%) - NSKE (5%) - Verticillium lecanii (0.004%) - imidacloprid 17.8 SL (0.0058%) observed effective in reduction of whitefly, thrips, aphid and beet armyworm and least effective against mite. Study revealed that imidacloprid 17.8 SL @ 0.5 ml/l, dimethoate 30 EC @ 1.7 ml/l, emamectin benzoate 5 SG @ 0.4 gm/l, fenazaquin 10 EC @ 1 ml/l, dicofol 18.5 EC @ 2 ml/l and acephate 75 SP @ 1 gm/l can be suggested to the farmers for the management of various pest on capsicum under shade net house conditions during summer for off season production

Conclusion

Studies on evaluation of IPM module for the management of pest complex under shade net conditions indicated that chemically intensive module (M-II) was found significantly superior. The module based on IIHR Bangalore (M-I) showed effective reduction of mite and bio-rationals module (M-III) with respect to crop damage (leaf curl due to mite), and chemically intensive module (M-II) was found significantly superior. Module-I (M-I) was moderate in effectiveness. Module-III (M-III) was found to be the least effective
