Evaluation of different germplasm and insecticides against tomato leaf curl virus affecting tomato

Tomato leaf curl disease caused by tomato leaf curl virus (ToLCV) is a major limiting factor in tomato cultivation in Jammu region of Jammu and Kashmir. Screening of different germplasm collected from different sources against the disease showed that out of fifteen germplasm, Mahaveer and Avinash-2 were found resistant, Samrudhi F1 and Namdhari 82535 were found moderately resistant while eleven germplasm viz. Heem Sohna, Sonali, Rupali, NS 816, NS 812, Pusa Ruby, Indus 1030, Arti, DVRT-2, Hybrid no. 15 and local showed susceptible reaction. Different insecticide (imidacloprid, thiamethoxam, dimethoate, acetamiprid, profenofos and oxy-demeton methyl) were evaluated against tomato leaf curl disease under field condition and it was found that at 70 DAT seed treatment + seedling dip + foliar application of imidacloprid showed lowest disease intensity followed by foliar application of imidacloprid, seed treatment with imidacloprid, foliar application of thiamethoxam, foliar application of dimethoate, foliar application of acetameprid, foliar application of methyl-o-demeton and foliar application of profenofos treatments, respectively. | Evaluation of different germplasm and insecticides against tomato leaf curl virus affecting tomato
