EVALUATION OF FUNGICIDES AND BIOCONTROL AGENTS IN THE MANAGEMENT OF EARLY AND LATE BLIGHT OF TOMATO

摘要

Early and late blight of tomatoes are the major biotic constraints hampering the yield and quality of the crop. Eleven treatments comprising of nine fungicides and two biocontrol agents were evaluated against the maladies in three consecutive seasons.The pooled data shows that in all the three seasons, Fenamidone 10% + mancozeb 50%-60 WG premix combination fungicide gave the best control for both early and late blight as compared to untreated check manifesting 75.34% and 74.62% disease control respectively. This was followed by Dimethomorph 50 WP + Mancozeb 75 WP with a per cent disease control of 69.43 and 66.20 for early and late blight respectively. Similarly in case of fruit yield plots treated with FenamidonelO%-Mancozeb 50%-60 WG reflected more than 75% yield than control.
