Field trial was conducted at Agricultural Research Station, Seethampeta, Srikakulam for two years 2018-19 and 2019-20 to evaluate the comparative efficacy of seven different insecticidal treatments (Biopesticides and synthetic insecticides) against pod borer complex viz., spotted pod borer (Maruca vitrata Geyer), gram pod borer (Helicoverpa armigera Hubner) and pod fly (Melanagromyza obtusa Malloch). The pooled data revealed that among all the treatments the synthetic insecticide treatment- T6 (Chlorantraniliprole 18.5 SC @ 30g a.i/ha, Flubendiamide 480 SC @ 30 g a.i/ha, Dimethoate 30 EC @ 600g a.i/ ha ) recorded lowest pod damage (0.76, 1.28 and 11.13 %) of all the three pod borers and highest pooled yield for 2018-19 and 2019-20 (1085.28 kg/ha) and per cent increase of yield over control was 87.86 per cent. Among the biopesticides Bt. kurastaki recorded highest pooled yield of 752.45 kg/ha with pod damage caused due to spotted pod borer (1.28), gram pod borer (2.52) and pod fly (22.6 %) followed by Azadirachtin 1500 ppm @ 5.0 ml/l recorded yield (749.31 kg/ha) with pod damage of 1.51, 2.11 and 19.95 per cent due to spotted pod borer, gram pod borer and pod fly respectively. The treatments Beauveria bassiana @ 5.0 g/ l and Metarhizium anisopliae @ 5.0 g/l recorded pooled seed yield of 727.95 and 707.49 kg/ha. [ABSTRACT FROM AUTHOR] |
