Abstract:
The present investigation entitled “seasonal incidence of the pests infesting green gram, Vigna radiata (L.) Wilczek was carried out during rabi season of 2018-2019 at Research and Educational Farm, Department of Agricultural Botany, College of Agriculture, Dapoli, Dist. Ratnagiri (M.S.).Seasonal incidence study revealed that the mean percent plant damage by stem fly was first observed from 51^st SMW (17 Dec-23 Dec 2018). No stem fly infestation was recorded in 50^th SMW (10 Dec-16 Dec) and onwards. As regards correlation with weather parameters, the mean percent damage of stem fly exhibited significant positive correlation with maximum temperature (r=0.725), minimum temperature (r=0.798), Bright Sunshine Hours (B.S.S.) (r=0.799). The aphid population was seen throughout crop period but declined on later stages of green gram. The whitefly infestation was noticed throughout the season but it was negligible.
