EFFICACY OF DIFFERENT INSECTICIDAL SEED TREATMENT AGAINST TERMITE IN WHEAT (TRITICUM AESTIVUM L.) CROP

摘要

Studies were carried over on the effect of different insecticidal seed treatments against termites with respect to wheat germination in Crop Research Farm Nawabgang of CSAUA&T, Kanpur (UP) during rabi 2010-2011. The treatments involved Bifenthrin 10 EC (Talstar)@ 0.5 g a.i. kg seed Thiamethoxam 35 FS (Cruiser) @ 0.7 g a.i kg seed Fipronil 5 SC (Regent) @ 0.3 g a.i kg seed Imidacloprid 70 WS (Gaucho) @ 0.7 g a.i kg seed Carbosulfan 25 DS (Marshal) @ 1.0 g a.i. kg seed Chlorphyriphos 20 EC (Dursban) @0.9 g a.i kg seed ‘and untreated as control for termite on wheat cv. K-8027. The data revealedsignificant differences of impact of various insecticidal treatments on the germination. Significantly highest per cent germination was recorded in Fipronil 5SC (95%) closely followed by Thiamethoxam 35 FS (92.66%) and Carbosulfan 25 DS (92.33%),Bifenthrin 10 EC (9Q.33%), Imidacloprid 70 WS (90.00%) and Chlorpyriphos 20 EC(89.66%), whereas, grain yield (g/m row and q/ha) was significantly higher in treated plot with fipronil followed by Imidacloprid and thiamethoxam ue., 38.61 and 18.17,37.38 and 17.75 and 36.25 g/m row and 17.50 q/ha, respectively.
