YMV disease in mungbean is one of the major disease causing heavy losses annually throughout the country. As the disease is transmitted by insect vector, management of vector is important to check the YMV disease that can minimise the losses. The present investigation was aimed to evaluate different IPM modules for management of YMV disease of mungbean.
Field experiments were carried out during Rabi season of 2016-17 and 2017-18 at the Research Farm of Regional Research and Technology Transfer Station, Chiplima, Sambalpur, Odisha, India. Population of whitefly was recorded on three leaves selected from top, middle and bottom canopy of the plant. Disease severity was recorded by using 0-9 scale.
The IPM module i.e. seed treatment with Thiamethoxam 25 WG @ 5 gm kg-1 of seed, installation of yellow sticky trap @ 50 ha-1 and spraying of Acetamiprid 20 SP @ 0.3 gm l-1 of water was found as the most effective among all other modules. Pooled analysis of two years data revealed that 65.5% YMV disease control and 59.3% reduction of white fly population over control were performed by the said IPM module. A maximum increase in yield (84.8%) and highest cost benefit ratio (1.77) were also achieved with the module.
