Abstract:
A field experiment was conducted at dry land farm, S.V. Agricultural College, Tirupati during kharif, 2019-20 to evaluate the efficacy of nine insecticides i.e., Thiacloprid 21.7 SC @ 0.25 ml l^-1, Thiamethoxam 25 WG @ 0.2 g l^-1, Spinosad 45 SC @ 0.3 ml l^-1, Spiromesifen 240 SC @ 1.0 ml l^-1, Diafenthiuron 50 WP @ 1.25 g l^-1, Dinotefuran 20 SG @ 0.4 g l^-1, Flonicamid 50 WG @ 0.3 g l^-1, Pymetrozine 50 WG @ 0.6 g l^-1, Dimethoate 30 EC @ 2.0 ml l^-1 against sesame leafhoppers. The pooled results of two sprays revealed that pymetrozine was most effective in reducing the leafhopper population, followed by dimethoate and thiamethoxam which were statistically at par with each other, while, spinosad and spiromesifen showed least efficacy in reducing leafhopper population.
