Effect of treatment on the fungus, Colletotrichum gloeosporioides and anthracnose of mango fruits
An effect of heat treatment on
Colletotrichum gloeosporioides Penz., causal pathogen of anthracnose of mango, was conducted Conidia treated with hot water 55°C for 5 min produced 1% of appressoria whereas untreated produced 100% of appressoria after 36 hr of incubation. Disease severity on mango fruits inoculated with hot water treated conidia was 1.3% whereas 14.9% on untreated. At the depth of 1 mm from fruit surface, an infection was reduced by 80% after treated with hot water at 55°C for 5 min. Disease incidence on inoculated mango fruits which were treated with hot water at 55°C for 5 min, vapor heat at 46.5°C for 10 min, hot water at 55°C for 5 min and vapor heat 46.5°C, and untreated was 0.4, 0.5, 0.2 and 29.4% respectively. Fruits treated with these treatments showed on significance difference in weight loss, total soluble sold, and total acid.
