Management of paddy stem borer in kharif paddy in Kheda district of Gujarat

The comparative efficacy of granular insecticides was evaluated on paddy at farmers’ fields in the Kheda district of Gujarat. The white ear heads were lower (1.70%) in the plots treated with T₃ [25 kg cartap hydrochloride 4G/ha at 20 day after transplanting (DAT) and second application at 45 DAT] and it was closely followed by T₂ (20–25 kg carbofuran 3G/ha at 25 DAT and second application of 20–25 kg cartap hydrochloride 4G/ha at 45 DAT) (2.30%) and better than T₁ (20 kg cartap hydrochloride 4G/ha at 10–12 DAT) (8.80%). The insecticidal applications significantly increased the grain yield of rice as compared to T₁-treated plots.
