Description Leaf curl is one of the important diseases causing huge yield losses in sunflower. One of the best treatments from the 3 year experimentation on management of leaf curl disease was validated in on farm validationexperiment along with farmers’ practice. It was concluded that the treatment i.e., seed treatment with imidacloprid 600FS @ 5ml/kg seed + foliar spray with diafenthiuron 50 WP @ 1.25 g/lit at 30 and 45 DAS (days after sowing)recorded less leaf curl incidence of 10.5% and less whitefly population of 1.75. Same treatment also recorded higher yield of 1798 kg/ha and B:C ratio of 2.4 when compared to control, which recorded more leaf curl incidence of 28.5and less yield of 1500 kg/ha. Hence, it was concluded that diafenthiuron is one of the best chemicals in management of leaf curl disease by acting on whiteflies.
