Sesamum, whitefly, leafhopper, phyllody, seed treatment, thiamethoxam, imidacloprid, yield, cost benefits


A field experiment was conducted at the Agricultural college, Naira during rabi, 2020-21 on the control of major insect pests on sesamum viz., leafhopper Hishimonus phycitis (Distant) and whitefly Bemisia tabaci (Gennadius) and phyllody disease. The results revealed that thiamethoxam 25WG @ 0.25 g/ l was very effective against both the pests with 72.2 and 50.5% reduction in incidence, respectively. Thiamethoxam was also effective against phyllody (PDI of 5.72), and gave a maximum seed yield of 6.50 q/ ha and B:C ratio (1:4.7). Seed treatment with imidacloprid 17.5SL @ 5 ml/ kg seed stood as the next best with B:C ratio of 1:3.7.
