Blackgram (Vigna mungo L.), commonly known as urdbean in India, belongs to the Leguminosae family. Yellow mosaic disease (YMD) caused by Mungbean Yellow Mosaic Virus (MYMV) stands out as the most serious disease and a significant bottleneck for blackgram cultivation and production. Henceforth, an attempt was made to know the effective insecticide for the management of whiteflies transmitting YMD in blackgram.
The field experiment was conducted on management of whiteflies vectoring YMD of blackgram by using different combination of insecticides during kharif 2023 at College of Agriculture, Vijayapur, UAS, Dharwad by using randomized complete block design (RCBD).
Seed treatment with imidacloprid 600 FS @ 5 ml/kg seed + foliar spray of (pyriproxifen 5% + difenthuron 25% SE) @ 2 ml/ l achieved the highest reduction of whitefly population over control of 83.63, 91.05 and 94.10 per cent at 30 DAS, 45 DAS and 60 DAS, respectively. It also resulted in the lowest disease incidence of 13.42, 17.55, 20.80 and 24.78 per cent at 30 DAS, 45 DAS, 60 DAS and 90 DAS (physiological maturity), respectively. Additionally, it produced the maximum yield of 7.87 q/ha with the highest B: C ratio of 2.89.
