Anil Kumar Singh, R.K.S. Tomar and Y.C.Rikhari


Mungbean yellow mosaic virus (MYMV) disease is one of the most vicious diseases of black gram and has been
renowned in India for more than five decades. The economic losses due to this virus account up to 85% in black
gram and spreading faster towards newer areas. Field experiments were carried out during the Kharif season of
2015 and 2016 by Krishi Vigyan Kendra, Datia, Madhya Pradesh to evaluate the five integrated pest management
module with conventional farmers’ practices against black gram sucking pest (white fly) and YMV under on farm
testing activity of the KVK at farmers’ field. Among the test modules, Module 4 (Resistant variety PU-31+ Spray with
Azadirachtin, 0.03% after 15 and 30 days of sowing + by Thiamethoxam 25% WG @ 0.2 g/lt WG after 45 day of
sowing) followed by Module 5 where Imidacloprid 17.8% SL @ 0.3 g/lt using in place of Thiamethoxam 25% WG
were found as the most effective treatments with more than 91 per cent mean reduction in nymphal population of
whiteflies and below 1 per cent incidence of YMV. 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 11.28 q/ha
in Module 4 followed by Module 5, Module 1, Module 2 and Module 3 were recorded in the IPM fields against 7.08
q/ha in farmers’ practise fields. Module 4 obtained maximum return with higher benefit cost ratio followed by
Module 5, Module 1, Module 2 and Module 3.
