Efficacy of different newer insecticides against mango leafhopper fauna

Abstract

An experiment was conducted to manage the mango leafhoppers with certain newer insecticides viz., Spinetoram 11.7 SC @ 0.4 ml l-1, Cyantraniliprole 10.26 EC @ 2 ml l-1, Pymetrozine 50 WG @ 0.6 gm l-1, Triflumezopyrim 10 SC @ 0.5 ml l-1 (at panicle initiation, at peanut stage and marble stage) Spinetoram 11.7 SC @ 0.4 ml l-1, followed by Beauveria bassiana @ 5 gm l-1, Cyantraniliprole 10.26 EC @ 2 ml l-1, followed by Thiamethoxam 25WG @ 0.3 gm l-1, Pymetrozine 50 WG @ 0.6 gm l-1, followed by Neem oil 10000 ppm 3 ml l-1, Triflumezopyrim 10 SC @ 0.5 ml l-1, followed by Spinosad 45 SC @ 0.4 ml l-1 followed by Triflumezopyrim 10 SC @ 0.5 ml l-1, Diafenthiuron 50 WP @ 0.5 – 1 gm l-1, followed by Acephate 75 SP @ 1.5 gm l-1, followed by Imidacloprid 17.8 SL @ 0.5 ml l-1 (Check), along with untreated control. Efficacies of these treatments revealed that Triflumezopyrim 10 SC @ 0.5 ml l-1 followed by Spinosad 45 SC @ 0.4 ml l-1 Triflumezopyrim 10 SC @ 0.5 ml l-1 have resulted in 96.57 per cent reduction of leafhopper population over control (ROC) were proved to be most effective treatment. The least per cent reduction of leafhoppers (58.13 % ROC) over control was recorded with Cyantraniliprole 10.26 EC @ 2 ml l-1.
