Field Efficacy of Insecticides in the Management of Yellow Mosaic Disease of Horsegram

Background: Horsegram [Macrotyloma uniûorum (Lam.) Verdc.] is a drought-tolerant legume widely cultivated in South Asia, known for its resilience in poor soil conditions. Yellow Mosaic Disease (YMD) poses a significant challenge to horsegram production in India, resulting in complete yield loss. So, an attempt was carried out to manage YMD in horsegram using different insecticides. Methods: For management of YMD of horsegram, a field experiment was carried out in randomized complete block design using different insecticides. Result: Seed treatment with imidacloprid 600 FS at 5 ml/kg and foliar spray with (pyriproxyfen 5% + diafenthiuron 25%) 30% SE at 2 ml/1 at 30, 45 and 60 days after sowing resulted in the lowest disease incidence of YMD and highest reduction of whitefly population over control with seed yield of 6.91 q/ha and B:C ratio of 1.69.
