Abstract:
The present investigation was conducted on the thirteen beneficiary farmer fields of Chickpea crop in the Village-Kharda, Taluka Babhulgaon, District Yavatmal during Rabi 2019-2020 and laid out in Randomized Block Design with two treatments and thirteen replications. Sowing was done by dibbling following similar recommended agronomic practices to all the treatments from sowing to the harvesting. The ETL based spraying of Emamectin benzoate 5% SG 5 ml (T₁) and ETL based spraying of biopesticides HaNPV 2% AS 10 ml (T₂) in 10 litter water was done at 50% flowering stage. At 7 days before spraying of Emamectin benzoate 5% SG in farmers practice and HaNPV 2% AS in the technology intervened, the infestation of pod borer was recorded to be 1.23 and 1.38 larvae per meter row length, respectively. After sprayings, it was revealed that the treatment of HaNPV 2% AS was found to be the most effective treatments which recorded average 0.89 larvae per meter row length over farmers practice i.e. Emamectin benzoate 5% SG recorded average 1.08 larvae per meter row length. However, the data revealed that the average pod damage at harvesting in the farmers practice was recorded to be 9.88% and 8.01% in second treatment of HaNPV 2% AS. The lowest pod borer infestation and percent pod damage was observed in spraying of HaNPV 2% AS (T₂) over spraying of Emamectin benzoate 5% SG (T₁). The yield data revealed that higher yield of 12.35 q/ha was observed in T₂- spraying of HaNPV 2% AS over T₁ farmers practice i.e. spraying of Emamectin benzoate 5% SG recorded yield of 11.88 q/ha.
