Abstract:
During the Kharif of 2021, a field experiment was carried out at the farmer’s field in selected villages of sirguppa taluk of Karnataka to assess the efficacy of some novel insecticides in combination with neem products against BPH and WBPH in a direct seeded rice (DSR) crop. The results showed that Buprofezin 25% SC @ 200 G.A.I. ha^-1 was the most effective treatment for the control of both BPH and WBPH, with 64.40 and 68.29 percent reductions over the untreated control, respectively. Buprofezin 25% SC A.I. ha^-1 (4954 kg ha^-1) increased grain yield by 63.55 percent compared to the untreated control.
