Abstract:
Field demonstrations were held during rabi 2018-19 on nine farmers' fields comprising 1.8 ha (0.2 ha/farmer) in Kumbhali village, Sakoli tahsil, Bhandara district, as well as 0.2 ha (ARS), Sakoli, Bhandara district. The demonstration plot was sprayed with HaNPV at a rate of 500 LE/ha at the ETL (Economic threshold Level) of Helicoverpa armigera (gram pod borer) crops, and it was compared to the farmer's practice plot (an untreated plot). The results revealed that, Spraying 500 LE/ha of HaNPV was found to be substantially more effective with lowest gram pod borer larval count (2.96 larvae/mrl), lower pod damage (14.46%) and higher grain yield (14.28 q/ha) in demonstration plots as compared to farmer practice plots (Untreated plots) with gram pod borer larval count of 4.67 larvae/mrl, at farmers field, grain yield of 9.71 q/ha was recorded with pod damage of 23.37 percent. Similarly, spraying of HaNPV @ 500 LE/ha was found significantly more effective with lowest gram pod borer larval count (2.03 larvae/mrl), lower pod damage (25.04%) and higher grain yield (16.72 q/ha) in demonstration plot as compared to farmer practice plot (Untreated plot) with gram pod borer larval count of 2.67 larvae/mrl, pod damage of 32.00% and grain yield of 12.58 q/ha at ARS, Sakoli farm. Hence, it is concluded that HaNPV @ 500 LE/ha should be applied effectively in order to control the chickpea gram pod borer and increase grain output.
