Abstract:

A field experiment was conducted on Okra, Abelmoschus esculentus (L.) to evaluate some newer groups of insecticides against shoot and fruit borer, Earias vittella. The experiment was lay out in RBD with three replication comprising eight treatments i.e. Indoxacarb @75g a.i/ha, Coragen@30g a.i/ha, Spinosad@100g a.i/ha, Profenophos@750g a.i/ha, Thiodicarb@750g a.i/ha, Bacillus thuringiensis@75g a.i/ha, Azadirachtin @ 2.5lit /ha including untreated control were taken for compression. The Coragen treated plot recorded lowest mean fruit damage (6.29 and 6.83%) followed by Spinosad (7.17 and 7.47%) and in control (30.96 and 33.14%). The maximum yield was recorded in treatment Coragen (118.02 and 117.10 q/ha) followed by Spinosad (115.65 and 114.85 q/ha) as compare to control (68.80 and 68.10 q/ha) respectively during Kharif, 2012 and Kharif, 2013. The highest cost benefit ratio was obtained in Coragen treated plot (1:9.27) followed by Indoxacarb (1:8.08), Spinosad (1:7.89) respectively. The Coragen treatment was more effective to reduce the infestation of fruit as well as to provide highest okra yield.
