Efficacy of bio-pesticides against Helicoverpa armigera, Hübner in Tomato

A field trial was conducted at three farmer's fields to study the role of bio-agents in management of tomato fruit borer. NPV with chick pea flour 1% + Jaggery 0.5% significantly reduced the larval population of Helicoverpa (93.1%), lowest fruit damage (6.9%) and higher yield (112.02 q/ha) was obtained over the control. In the treatment of NPV mixed with sandovit 0.2%, the population reduction (63.8%), lowest fruit damage (12.6%) and maximum fruit yield (118.21 q/ha) was obtained. Endosulfan 35 EC@0.07 was most effective for the reduction of population (79.6%), minimum fruit damage (12.4%) and maximum fruit yield (176.4 q/ha) followed by haNPV@250 LE+0.035% endosulfan 35 EC.
