A field experiment was conducted to evaluate the integrated pest management practices against pod borer chickpea during 2013-14 and 2014-15 with medium grain size chick pea var. JG 63. Chick pea is a measure pulse crop of Madhya Pradesh affected with several insect pests from their vegetative stage to maturity stage, among them pod borers are serious pests. Average two years data indicated that chlorantraniliprole was reduced 98% pod bore infestation followed by emamactin benzoate and profenofos whereas minimum effect of HaNPV and Beauveria bassiana bio-pesticides were noted in the experiment. Average two years data indicated that minimum damage of pod (2. 68 and 0. 34% at 3 & 10 days observation, respectively) found in treatment applied initially sprayed with chlorantraniliprole@ 80 gram/ha followed by Ememectin benzoate and profenophos. Among the chemical treatment, highest average pod borer infestation damage infested by all three borers was recorded in profenophos treated plot (6.05% at 3rd days @ 2.55% at 10 days). In control plot, average pod infestation was 18.68 and 23.29%, respectively at 3 & 10 days interval. Plot treated with microbial insecticides significantly recorded lower pod damaged (8.66%) in comparison to control plot (23.29). As well as yield was concern, highest yield (20.95 q/ha), net profit (Rs 42745 and B:C ratio (3.12) was found in chlorantraniliprole sprayed treatment. Regular observation of the trial indicated that initial population of pests in standing crop managed by the application of integrated pest management practices like pheromone trap and light trap from each treatment. Time and dose of insecticides application was more important than the type of insecticide. Flowering and grain formation stage were more vulnerable to attack of pod borer maximum damage.
