Effect of different biopesticides and insecticides treatments on chickpea (Cicer arientinum) for management of Helicoverpa armigera (Hubner)

Abstract

The present investigation was undertaken to find out suitable and low cost substitute for the management of Helicoverpa armigera (Hubner) on chickpea by using microbials and botanicals. The field trial was laid out in the premises of Insectary, Entomology Section, College of Agriculture, Nagpur, during the rabi season of 2013-14. The experiment was laid out in randomized block design (RBD) with three replications and eight treatments including control (water spray). The observations were recorded on average per cent reduction in the larval population were recorded. Considering all the parameters, the treatment spinosad 45 SC 0.01 % recorded highest 76.17 per cent reduction in the larval population with minimum pod damage (18.64 %) and produced 15.23 q/ha yield
