Evaluation of various fungicides and bio-agents against the powdery mildew of mango (in vivo) under south Gujarat condition

Abstract

Among all diseases, Powdery mildew (Oidium mangiferae Berthet) of mango is emerging as one of the most common, wide spread and serious disease throughout the world and causes significant yield losses. The most serious losses occur when flowering and growth flushes are infected during cool and dry conditions. The management studies against powdery mildew of mango in field condition showed hexaconazole @ 0.01% recorded highest per cent disease control of powdery mildew and also significantly inhibited growth of the pathogen and proved strongly fungi toxic at the given concentrations. Wettable sulphur @ 0.3% significantly inhibited disease incidence and at par with the best one. The next best in order of merit was Pseudomonas fluorescence @ 5% inhibited the disease incidence.
