摘要

Field studies were carried out during April to June 2004 and 2005 to evaluate the effectiveness of biological agents like Bacillus thuringiensis, nuclear polyhedrosis virus and Trichogramma chilonis to assess the impact of their integrated use on fruit damage, yield and cost benefit analysis in tomato. The lowest fruit damage (7.2 and 7.01%) and the highest yield (270.6 and 263.7 q/ha) was obtained with all-insecticide module. Amongst the biopesticides, lower fruit damage (7.57 and 8.23%) was obtained in B.t.k. alone and T. chilonis HaNPV modules. However, among biopesticide modules, higher yield was obtained in B.t.k. - HaNPY module. The highest CBR of 1:16.3 and 1:18.56 were obtained with all insecticide module, while amongst biopesticide modules,the CBR was maximum in B.t.k. - HaNPV module (1:7.47) during 2004 and that of T. chilonis releases (1:8.49) during 2005.
