DEVELOPMENT OF AN INTEGRATED MANAGEMENT APPROACHES FOR MUNGBEAN YELLOW MOSAIC VIRUS OF GREEN GRAM [VIGNA RADIATA (L.) WILCZEK ] IN BUNDELKHAND ZONE

Abstract

Mungbean yellow mosaic virus (MYMV) disease is one of the most vicious diseases of green gram and has been renowned in India for more than five decades. The economic losses due to this virus account up to 85% in green gram which is spreading faster towards newer areas. A field experiment was carried out by Krishi Vigyan Kendra during kharif seasons at the farmers’ fields in villages Sitapur, Datia district of BundelKhand zone to evaluate the five integrated pest management module including conventional farmers’ practices against green gram sucking pest (white fly) and YMV. Among the test modules, Module 3 (Resistant variety TJM 3+ Seed treatment with Imidacloprid 17.8 % SL @ 5 ml/kg seeds +2 sprays of Imidacloprid 17.8 % SL @ 0.5 ml/l water) found as the most effective treatments with more than 91.58 percent mean reduction in nymphal population of whiteflies and below 2 percent incidence of YMV followed by Module 2 (Module 1 +2 sprays of Neem oil (5% Azadirachtin) @ 3.0 ml/l), Module 4 (Module 1 + 2 sprays of Triazophos 40 % EC @ 1.5 ml/l), Module 1(Resistant variety TJM 3+ Seed treatment with Imidacloprid 17.8 % SL @ 5 ml/kg seeds). All the IPM modules were found significantly superior over the conventional farmers’ practices in reducing the incidence of YMV in black gram. Higher mean yield of 9.35 q/ha in Module 3 followed by Module 2, Module 4, and Module 1 were recorded in the IPM fields against 6.75 q/ha in farmers’ practise fields. Module 3 obtained maximum return with higher benefit cost ratio followed by Module 2, Module 4, and Module 1.
