Integrated management of flower thrips and pod borers of mungbean using blue sticky trap and insecticides

Abstract

Effectiveness of integrated management approaches using blue sticky trap, bio and synthetic
insecticides were evaluated against flower thrips and pod borers of mungbean during kharif-I of 2020,
2021 &2022. All of the management packages significantly reduced flower infestation by thrips, thrips
population and pod borer infestation in mungbean. The lowest percentage of flower infestation
(23.33%) was found in IPM package-3: (Blue sticky trap + two spraying of chlorfenapyr (Intrepid 10
EC) @ 1 ml/l at 100% flowering and 100% podding stage + third spraying with Emamectin Benzoate
(Proclaim 5 SG) @ 1 g/l at seed developing stage) which was similar with other IPM packages and
farmers practice. The lowest percentage of pod borer infestation was observed in IPM package-2:
(Blue sticky trap + two spraying of Bio-Chamak (Celastrus angulatus 1% EW) @ 2.5 ml/l at 100%
flowering and 100% podding stage + third spraying with spinosad (Success 2.5 EC) @ 1.2 ml/l at
seed developing stage) which was also similar with other IPM packages and farmers practice. The
highest yield and additional return come from IPM package followed by farmer’s practice. But the
highest benefit (MBCR 4.07) comes from farmers practice. This might be due to higher cost of IPM
components brought down the profit margin and showed the lower MBCR than that of farmers
practice. Although IPM packages under this study are not financially profitable as farmers practice
but considering environment friendliness, the IPM package-2 might be useful for controlling flower
thrips and pod borers of mungbean with higher yield in the insects prone cropping areas without
harming the ecosystem.
