Management of tomato leaf curl disease

Screening of fifteen germplasm lines collected from different sources against tomato leaf curl disease under field conditions was done. Two lines, Mahaveer and Avinash-2 were found resistant. Samrudhi F1 and Namdhari 82535 were found moderately resistant while other eleven lines viz. Heem Sohna, Sonali, Rupali, NS 816, NS 812, Pusa Ruby, Indus 1030, Arti, DVRT-2, Hybrid no. 15 and Local were susceptible. Different insecticides (imidacloprid, thiamethoxam, dimethoate, acetamiprid, profenofos and oxy-demeton methyl) were also evaluated against tomato leaf curl disease on cv Pusa Ruby under field conditions. The results showed that seed treatment+ seedling dip + foliar application with imidacloprid showed lowest disease intensity of 8.14% as compared to untreated control.
