Abstract

Present project was carried out to check the efficacy of microbial and botanical insecticide against Cnaphalocrocis medinalis, to assess the effective dose of Trichogramma chilonis for a successful control of the rice leaf folder and study the synergistic effect of Trichograma sp. and biopesticides for the sustainable control of C. medinalis. It is evident from the results that minimum post treatment increase in infestation (2.67%) was recorded against T3 (1,00,000 eggs) and was, statistically at par, with that recorded from T4 (1,25,000 eggs) with an increase in percent infestation of 3.683%. These differed significantly from those recorded from T1 and T2 with infestation increase of 5.17 and 4.59% respectively. Maximum increase in post treatment infestation was recorded in control treatment. The results of the experiment related to biopesticides shows that neem and Bt gave good results and shown minimum post treatment increase in infestation. 6.087 and 4.093% respectively. The results of the experiment regarding the integration of the best treatments of the Trichogramma egg releases and bio-pesticides shows that minimum increase in post treatment infestation (1.373%) was recorded from those plots which were treated with Trichogramma + Bt (Bacillus thuringiensis) + Neem (T6) and was statistically at par with T5 , T4 and T2 which showed 2.15, 2.40 and 2.506% increase in post treatment infestation of C. medinalis. The control treatment showed maximum increase in post treatment increase of infestation of C. medinalis (8.053%).
