Estimation of yield losses due to spotted pod borer, Maruca testulalis in cowpea


Author(s): Rathwa MG, Patel VN and Makwana AB

Abstract: Investigations were carried out to evaluate the yield losses caused by spotted pod borer, Maruca testulalis on cowpea during kharif, 2015 at College Farm, Junagadh Agricultural University, Junagadh. The results revealed that lower larval population of pod borers was observed in protected plots than unprotected plots. Significantly minimum pod damage (15.10 %) were recorded from protected plots by providing protection with the Spinosad 45 SC 0.009 per cent and Profenophos 50 EC 0.05 per cent alternative at 10 days interval intervals starting from flowering initiation to the pod maturity stage of the crop, 339.93 kg/ha yield loss can be saved. Total avoidable yield loss could be worked out as 41.14 per cent.
