In vitro evaluation of non-systemic fungicides against Colletotrichum gloeosporioides causing fruit rot in banana

Abstract

Banana (Musa paradisiaca L.) crop suffers from several fungal diseases, among which fruit rot caused by Colletotrichum gloeosporioides is one of the serious disease observed regularly in banana growing areas. Therefore, efforts were made to evaluate the different non-systemic fungicides in vitro condition against Colletotrichum gloeosporioides. Among the seven non-systemic fungicides evaluated in vitro against C. gloeosporioides, the pathogen was completely restricted by four non-systemic fungicides namely mancozeb 75% WP, copper oxychloride 50% WP, copper hydroxide 77% WP and zineb 75% WP at all three test concentrations (@ 1500, 2000 and 2500 ppm), whereas, propineb 70% WP (@ 2000 and 2500 ppm) and chlorothalonil 75% WP (@ 2500 ppm), also shows complete mycelial inhibition. These were followed by captan 50% WP, of the test pathogen.
