摘要

Fieldexperiments were conducted on chilli crop to assess the bioefficacy of spinosad 45 SC on chilli thrips and pod borer at Regional Agricultural Research Station, Lam, Guntur during 2002-03 and 2003-04 seasons. Spinosad 45 SC tested at 100,125,162.5 and 200 mL ha~(-1) were effective against chilli thrips Scitrothrips dorsalis and pod borer Spodoptera exigua. Spinosad 45 SC @ 125 mL ha~(-1) exhibited efficacy equal to higher doses and is the optimum dose for control of thrips and pod borer on chilli crop. Foliar application of spinosad at 200 mL ha~(-1) (1208 kg ha~(-1)), followed by spinosad at 162.5 mL ha~(-1) (1184 kg ha~(-1)), 125 mL ha~(-1) (1120 kg ha~(-1)) and 100 mL ha~(-1) (1086 kg ha~(-1)) recorded the maximum pod yields and are statistically on par with each other but significantly superior to endosulfan, fipronil and chlorpyriphos.
