ABSTRACT
The yield loss in chickpea due to pod borer was reported as 10 to 60 per cent in normal weather conditions, while it was 50 to 100 per cent in favorable weather conditions, particularly in the state where frequent rain and cloudy weather is prevailing during the crop season. The present studies were carried out on integration of various practices for the management of Helicoverpa armigera in rainfed areas of Chhattisgarh, India during 2009-10. In this selected rainfed location Chickpea variety 'Vaibhav' was selected for evaluating various strategies such as Integrated pest management (IPM) tools, chemical, biological, plant origin and microbial control, individually and in various possible combinations, for the management of H. armigera at three different locations. Integration of IPM tools, chemical, HNPV and plant origin insecticides proved to be the most effective in reducing the larval population. The larval population of the combined effect of IPM was found significantly best from pesticide, HNPV and plant origin insecticides alone. Chemical and Neem seed kernel extract (NSKE) also controlled the larval population significantly, but was inferior to the above combine effect of IPM tools.
Key words :
Helicoverpa armigera, integrated pest management, NSKE, rainfed chickpea.
