Integrated pest management studies against pests of Abelmoschus esculentus (L.) Moench

Abstract:
Studies on integrated pest control techniques were conducted in order to combat the okra pest complex, Abelmoschus esculentus (L.) Moench. The main pests of the okra crop were the insects jassid, whitefly, mite, and shoot and fruit borer. The IPM modules M2 (Im-idaclorpid + B. bassiana + Spinosad + Destruction of infested shoots and fruits) and M1 (Im-idacloprid + B. bassiana + Spinosad) were found to be most effective against jassid and whitefly, while modules M4 (B. bassiana + NSKE + Acephate + Btk + Destruction of infested shoots M8 (M. anisopliae+ NSKE + Spinosad + Btk + Destruction of infected shoots and fruits) and M3 (B. bassiana + NSKE + Spinosad + T. chilonis + Destruction of infested shoots and fruits) were determined to be the most efficient modules against shoot and fruit borer. The standard check M9 (Dimethoate with alternate sprays of endosulfan) had the highest yield of okra fruits, followed by M6 (Acephate + M. anisopliae+ Spinosad + Destruction of infested shoots and fruits), and M4 (B. bassiana + NSKE + Acephate + Btk + Destruction of infested shoots and fruits) had the lowest yield. The normal check M9 (Dimethoate with alternating spray of endosulfan) and module M5 (Acephate + M. anisopliae+ Spinosad) both had the greatest benefit cost ratios, whereas M3 (B. bassiana + NSKE + Spinosad + T. chilonis + Destruction of infected shoots and fruits) had the lowest benefit cost ratio.
