Abstract

The field trail was conducted during Kharif 2022 to evaluate the cost benefit ratio by using different insecticidal applications viz., NSKE 10% T1 @ 10gm/L, Beauveria bassiana 1.15% WP (1x108 CFU/gm) T2 @ 5gm/L, Spinosad 45 SC T3 # 0.5ml/L, Metarhizium anisopliae 4% WSP (1x108 CFU/gm) T4 @ 5ml/L, Imidacloprid 17.8 SL T5 @ 0.3 ml/L, Nisco sixer plus T6 @ 1.5ml/L, Neem oil 5% T7 @ 5ml/L and untreated control T8 in three replications against shoot and fruit borer, Earias vittella (Lepidoptera: Noctuidae), management on okra. Obsevations were taken on percent infestation of shoot and fruit on day before, 7DAS and 14DAS after two sprays Results revealed that highest yield is recorded in Spinosad 45 SC (101.4 q/ha), followed by nisco sixer plus (82.2 q/ha), Imidacloprid 17.8 SL (72.5 q/ha). Insecticidal treatment with Spinosad 45 SC with 1:5.66 had the highest cost benefit ratio, followed by Nisco sixer plus (1:4.99).
