Screening of fungicides against anthracnose disease of mango on nursery seedlings

Abstract

Mango (Mangifera indica L.) is one of the important tropical and subtropical fruit crop. Eventhough it is hardy plant, susceptible to many pests and diseases, among the diseases, anthracnose caused by Colletotrichum gloeosporioides is one of the most devastating diseases causing heavy losses in postharvest fruits. But, in the recent years, the disease become more problematic in nursery seedlings as well and it is one of challenging problem to manage disease under nursery. By keeping the view, systemic and nonsystenic fungicides were screened against anthracnose disease under nursery. Among different fungicides tested, minimum per cent disease index (7.50 %) and maximum per cent disease reduction (76.72 %) over control was recorded in trifloxystrobin + tebuconazole at 0.05 per cent concentration followed by tebuconazole (9.72 %) with 69.84 per cent disease reduction over control. Whereas, maximum per cent disease index (24.96 %) with minimum per cent reduction (22.55 %) over control was recorded in mancozeb at 0.3 per cent concentration.
