Role of vermiwash foliar spray combined with fertilizer levels on insect pest incidence in greengram

To evaluate the effect of fertilizers and foliar spray of vermiwash on pest population in greengram, a field experiment was conducted at the College Farm, College of Agriculture, Rajendranagar, Hyderabad during the rabi season of 2023-2024. The experiment was laid out in a randomized block design with three replications. The results revealed that the treatments did not show a statistically significant effect; however, numerically lower populations of nymphs and adults of whitefly (Bemisia tabaci) and bean pod borer (Maruca vitrata) were observed with the application of Foliar spray of 3% vermiwash at vegetative, preflowering stage and pod formation stage, higher pest population was observed in the application of 100% RDF.
