Bioefficacy of newer insecticides against tomato fruit borer (Helicoverpa armigera Hubner) and leaf miner (Tuta absoluta Meyrick)

DR Kachave, MM Sonkamble and SK Patil

As regards the fruit damage, significantly maximum per cent reduction of fruit damage by H. armigera and T. absoluta was observed in Flubendiamide 20 WG @ 100 g/ha (66.31%) and Emamectin benzoate 5 SG @ 200 g/ha (71.39%), respectively. Rest of the insecticides treatment were also significantly superior in reduced fruit damage in the range of 64.25 - 49.69 and 68.20 -51.14 per cent by H. armigera and T. absoluta, respectively over untreated control. The highest marketable fruit yield of tomato was recorded in Flubendiamide 20 WG @ 100 g/ha (59.72 q/ha) and it was at par with Spinosad 45 SC @ 100 L/ha (57.14 q/ha). Rest of the insecticides treatment were also significantly harvested higher fruit yield in the range of 55.62 – 45.15 q/ha over untreated control (25.15 q/ha). The highest ICBR was recorded in Lambda cyhalothrin 5 EC @ 300 L/ha (1:12.99), followed by Indoxacarb 14.5 SC @ 200 L/ha (1:12.08), Profenophos 50 EC @ 1250 L/ha (1:10.48), Spinosad 45 SC @ 100 L/ha (1:7.05) and Emamectin benzoate 5 SG @ 200 g/ha (1:6.82).
