Abstract

To observe the comparative efficacy of spinosad individual and in combination with botanicals against okra shoot and fruit borer (Earias vitella Fabricius). In present study among all the treatments, minimum shoot infestation was recorded in treatment T1- Spinosad @ 45 SC (4.42 %) and T2- NSKE 5% + spinosad @ 45 SC.(4.55 %) which are most effective and significant to each other, and followed by T4- Turmeric cured extract 3.5% + spinosad @ 45 SC (4.62 %), T5 - Custard apple leaf extract + spinosad @ 45 SC (5.22 %), T3- Karanj oil + spinosad @ 45 SC (5.42 %), T7 -Garlic and chilli extract + spinosad @ 45 SC (5.49 %), T6 - Neem oil + spinosad @ 45 SC (6.70 %) and minimum fruit infestation was recorded in treatment NSKE 5% + spinosad @ 45 SC (12.42 %), followed by Turmeric crude extract (3.5 %) + spinosad @ 45 SC (15.5 %), Karanj oil + spinosad @ 45 SC (17.03 %), T1- spinosad@ 45 SC (17.17 %), Custard apple leaf extract + spinosad @ 45 SC (18.75 %), Garlic and chilli extract + spinosad @ 45 SC (18.97 %), Neem oil + spinosad @ 45 SC (19.9 %).
