Abstract:
Field experiment was carried out to assess the economics of plant protection treatments against legume pod borer (Maruca vitrata) on greengram during two consecutive years of 2021 and 2022. Emamectin benzoate gave the highest yield which was 9.35 q/ha followed by the Azadirachtin 5% EC with 8.23 q/ha and Bacillus thuringiensis @ 2×10¹¹ spores/ml (8.23 q/ha). However, the lower yield of 6.50 q/ha was recorded in the Verticellium lacani @ 1×10⁸ Spores/ml treated plot as compared to 4.70 q/ha untreated control. The ICBR calculated for Emamectin benzoate 5 SG, Bacillus thuringiensis @ 2×10¹¹ spores/ml, Pungam oil (Karanj), Verticellium lacani @ 1×10⁸ Spores/ml, Beauveria bassiana @ 1×10⁸ spores/ml and Azadirachtin 5% EC was 1:5.89, 1:4.79, 1:3.23, 1:2.25, 1:2.51 and 1:1.51, respectively.
