Abstract:
A field experiment was conducted at the entomological research farm of College of agriculture, Gwalior during Kharif season of 2019. An experiment was laid out in Randomized Block Design (RBD), with eight treatments including the untreated control and three replications. The mean percent reduction in jassid population in both first and second insecticidal spray revealed that all the insecticidal treatments proved significantly superior over the control in reducing the pest population. Though, treatment with Acetamiprid 20 SP @ 120 gm/ha (83.83%) has given a significant decline which was at par with Imidacloprid 17.8 SL @ 150 ml/ha (82.00%) followed by Emamectin benzoate 5 SG @ 150 gm/ha (79.82%) which was also at par with Chlorantraniliprole 18.5 SC @ 150 ml/ha (76.76%). The lowest per cent reduction was recorded in NSKE 5% @ 25 kg/ha (60.79%). Further, the mean percent reduction in whitefly population in both the sprays revealed that all the insecticidal treatments were also proved to be significantly superior over the control in reducing the field population. Though, treatment with Acetamiprid 20 SP @ 120 gm/ha (84.18%) has given a significant highest decline which was at par with Imidacloprid 17.8 SL @ 150 ml/ha (82.00%) followed by Emamectin benzoate 5 SG @ 150 gm/ha (79.16%), Chlorantraniliprole 18.5 SC @ 150 ml/ha (73.11%) which was found at par with Thiacloprid 45 SC @ 300 ml/ha (70.63%). The lowest per cent reduction was recorded in NSKE 5% @ 25 kg/ha (60.15%).
