Assessment of various fungicides and bio-agents against the powdery mildew of mango (In vitro)

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. In vitro evaluation of seven fungicides and two bio agent against O. mangiferae showed hexaconazole @ 0.01% and Wettable sulphur @ 0.3% were highly effective and inhibited the conidial germination. The next best in order of merit was Pseudomonas fluorescence @ 5% inhibited comparatively least growth of the pathogen.
