Abstract:
A field experiment was carried out to evaluate the bioefficacy of profenophos 50% EC against leaf folder, Cnaphalocroris medinalis, stem borer Scirphophaga incertulas and green leafhopper, Nephotettix spp. on paddy. In the present experiment the efficacy of three doses of profenophos viz., 800, 1000 and 1200 ml/ha, cartap hydrochloride 50% SP @1000 g/ha, fipronil 5% SC @1000g/ha, monocrotophos 36% SL 1250 ml/ha and chlorpyrifos 20% EC1250 ml/ha were studied. The results confirm that cartap hydrochloride was the best treatment in reducing leaf folder (0.56 leaf folder/hill) and stem borer (0.55 dead heart/hill) whereas profenophos @ 1200 ml/ha was found superior in reducing leafhopper population effectively (96.33 hoppers/hill).
