Comparative efficacy of some insecticides on early shoot borer (Chilo infuscatellus Snellen) incidence in sugarcane under subtropical India

Comparative efficacy of some insecticides on early shoot borer (Chilo infuscatellus Snellen) incidence in sugarcane under subtropical India

Si x c h emi c al s n amel y ; Chlorantraniliprole 20 S.C. @ 0.05 Kg a.i./ha), Chlothianidine 50% WDG @ 0.05 Kg a.i./ha), Imidacloprid 200 S.L. @ 0.02 Kg a.i./ha), Azadiractin 0.15 E.C. 0.03% a.i./ha) and Cartap Hydrochloride 50 W.S.P. 0.75 Kg a.i./ha) along with Chlorpyriphos 20 E.C. @ 1 Kg a.i./ha) as check insect i cide were ev aluated. Chlorantraniliprole @ 0.04% was most effective as it exhibited least dead hearts of 2.85% with the decrease of 83.43% in the incidence over control followed by Chlorpyriphos @ 0.5% with 4.69% dead hearts and it was statistically at par with Chlothianidine @ 0.25% and 0.50%. Higher dead hearts of 7.21% were observed with Imidacloprid @ 0.02 per cent whereas Azadiractin @ 0.5 per cent was found to be least effective insecticide exhibiting 10.33% dead hearts. Dead hearts in the untreated control were 17.21%. Hence, it can be suggested that Chlorantraniliprole @ 0-04% could be the most preferred option whereas Chlorpyriphos 20 EC 0.5%, Chlothianidine @ 0.5% and Imidacloprid @ 0.02% can be the next choice for ESB control.
