Abstract: Capsicum a member of family Solanaceae, is commonly known as sweet pepper, bell pepper and Shimla mirchi. Under protected cultivation, capsicums are widely grown due to higher productivity and economic feasibility. However, diseases of viral nature affect production significantly, both in terms of yield and quality. To know the incidence of viral diseases and prevalence of vector populations, an extensive survey was conducted during rabi 2017and18 in major capsicum growing areas of Karnataka under protected cultivations. Virus infected capsicum plants exhibit symptoms of curling, cupping, puckering, mosaic, reduced plant growth and bushy appearance, chlorotic rings on leaves and fruits etc. Results of survey revealed that the highest mean incidence of leaf curl disease (27.92%) in Dharwad, mild mottle disease (27.61%) in Belagavi and mosaic disease (21.39%) in Chikkaballapur districts were recorded. Among the different crop growth stages, flowering stage recorded maximum mean incidences of leaf curl (20.32%), mild mottle (22.03%) and mosaic disease (18.16%). The highest mean incidence of 20.92 per cent leaf curl, 19.04 per cent mild mottle disease and 17.92 per cent mosaic diseases were observed under shade net condition. Among the different varieties/hybrids, hybrids from Namdhari seeds recorded highest mean incidence mild mottle disease (23.11%), leaf curl (21.85%) and mosaic disease (17.96%).
