ABSTRACT
Investigations were carried out to evaluate the efficacy of biopesticides against Helicoverpa armigera (Hubner) Hardwick in tomato. The experiment was conducted during rabi season, 2012-13 and 2013-14 at College Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand. Among nine biopesticides, spinosad 45 SC @ 0.025 per cent proved to be most effective treatment by recording lower infestation of H. armigera in terms of egg (0.73/ 3 twigs), larvae (0.36/ 3 twigs), fruit damage (7.68%) with higher tomato fruit yield (179.50 q/ ha) and net realization (` 65,120/ ha) without interfering natural enemies followed by HaNPV @ 250 LE/ ha and Neemazal 5 EC @ 0.1%.
Key words :
Biopesticides, HaNPV, Helicoverpa armigera, ICBR, Neemazal, Spinosad, Tomato.
