Abstract : Mango Anthracnose (Glomerella cingulata) causes up to 50% of losses in the post-harvest stage. The objective of this research was to assess the management of this disease in post-harvest through thermotherapy and chemical synthesis products such as Acibenzolar-s-metil, Procloraz and Thiabendazole. Fruits from the Creole variety (Hilacha) highly susceptible to Anthracnose were used. Eight treatments with two fruits per treatment and two repetitions in a complete random blocks design were performed. After the treatment the fruits were allowed to dry at room temperature before passing them through incubation under moist chamber conditions to obtain a complete ripeness degree, time in which the disease becomes accentuated. After the first Anthracnose visual symptom, 3 days interval readings were made in order to estimate the degree of severity of the diseases. The readings finished when the control reached 50% severity. The quality of the fruits was evaluated based on the Codex Alimentarius norm. There was an additive effect of thermotherapy with chemical synthesis products, being Thiabendazole the best product, followed by Procloraz, with severities of 0.50 and 1.75%, respectively. Thiabendazole produced extra quality fruit improved with thermotherapy.
