Fungicide tolerance of antagonists in the management of mango anthracnose caused by Colletotrichum gloeosporoides

Abstract

In the present study, fungicide tolerance of antagonists (yeast and Lactobacillus) with two fungicides viz., Mancozeb and Ridomil gold were conducted using turbidometric method. Findings of study revealed that, ridomil and mancozeb treatments could inhibit the growth of yeasts and Lactobacillus to some extent but did not completely inhibit. In this study, it was found that potential yeast and Lactobacillus antagonists were tolerant to both mancozeb and ridomil fungicides up to 2000 ppm concentrations. This result implies that the antagonistic yeast and Lactobacillus isolates were not adversely affected by both mancozeb and ridomil fungicides. So, these isolates can form an important component of Integrated disease management of mango anthracnose.
