Early blight is a major production constraint in tomato wherever this crop is grown and it accounts for loss in tomatoes ranging from 5 to 50% world wide. Therefore, to manage the disease effectively a study was conducted to evaluate the bioefficacy of different fungicides viz. mancozeb, chlorothalonil, copper hydroxide, ziram, metalaxyl 8%+ mancozeb 64%, dimethomorph 9%+ mancozeb 60%, fenamidone, fosetyl Al+ propineb, cymoxanil 8%+ mancozeb 64% and two bioagents viz. Pseudomonas fluorescens and Trichoderma viride against Early blight of tomato during four consecutive years from 2009 to 2013 at AICRP on Vegetable Crops, OUAT, Bhubaneswar during rabi season. Tomato variety Utkal Kumari was transplanted and the trial was laid out in a randomized block design (RBD) with twelve treatments and three replications in a plot size of 3.0 mx 2.7 m and with a spacing of 50 cm x 40 cm. Among the 12 (twelve) tested treatments including control, all the treatments significantly reduced the Early blight disease intensity as compared to control. Mancozeb@ 0.2%(T1) was found to be most effective in reducing the disease intensity (mean PDI-7.85) which significantly varied from control. The same treatment also registered maximum percent disease reduction over control (84.87%) corresponding to the maximum mean fruit yield (336.7 q/ha) with B: C ratio of 3.5. However, the control plot recorded maximum mean disease intensity (PDI-51.89) with minimum mean fruit yield (214.4 q/ha). The bioagents viz. Pseudomonas fluorescens and Trichoderma viride also significantly reduced the disease intensity as compared to control but both the treatments were at par in minimising the disease intensity. No phytotoxic effects such as stunting, chlorosis, necrosis, discolouration, blackening and burning/malformation were observed.
