Integrated disease management in tomato

Abstract

Tomato is one of the most important vegetable crop grown in Telangana in kharif, rabi and summer seasons. It is affected by early blight, late blight, leaf curl virus, collar rot and fusarium wilt diseases which play a key role on yield parameters. An experiment was conducted with six treatments and four replications to test the effective module for the management of these diseases. Among the tested modules, Integrated module which includes nursery treatment with seed pro: seed priming @ 4g/kg ,ii) soil application @10g/Kg of soil while potting and iii) soil drenching @ 5% after seed germination. Main field treatment: seedling dip with 0.1% (carbendazium 12% + Mancozeb 63% WP) +spray with Acephate 75% WP @ 1.5 g/l on 10 day after transplanting +spray with fipronil 5%SC @ 1.5 ml/l on 20 DAT+ spray with copper hydroxide 77% WP (2.0g/l) on 20 DAT +spray with imidacloprid 70% WG @ 2g/15 1 on 40 DAT + spray with fenamidone 10% +Mancozeb 50WDG (0.25%) two to three time from 45 DAT at 10 days intervals was effective in the management of diseases (Damping off, Fusarium wilt, Collar rot, Early blight, Late blight, Bacterial leaf spot and Tomato leaf curl) in tomato and recorded highest yield with no residues and highest benefit cost ratio.
