Abstract

  Chilli (Capsicum annuum L.) is an economically important and widely cultivated crop of India. Chilli leaf curl virus is one of the major limiting factors in chilli production, which is drastically decreases yield. The significant symptoms of chilli leaf curl are curling of leaf margin, reduction in leaf size, vein clearing accompanied by puckering, thickening and swelling of the veins. The maximum leaf curl disease was observed in 19th standard week when the white fly population was highest in the field. The increase or decrease of leaf curl virus disease of chilli was found directly correlated with vector population and vector population was determined by environmental factors. Three cultivars of chilli viz., Surajmukhi, Japani long and Pusa Jwala were showed highly resistant against leaf curl disease. Seed treatment with raw cow milk and Trichoderma viridae showed the reducing trends of chilli leaf curl disease incidence. Whereas seed treatment with imidacloprid 70 WS (5 gm/kg) along with two sprays of imidacloprid 17.8 SL (0.24 ml/lit) at 45 and 60 days after planting recorded least number of whiteflies and leaf curl virus per plant with significant increase of growth and yield.
