Abstract

This study assessed the effect of acetylsalicylic acid (ASA) and 1-methylcyclopropene (1-MCP) to control anthracnose in papaya (cultivar Golden). Disinfested-surface fruits were inoculated with Colletotrichum gloeosporioides and then the compounds were applied. The lesion diameters and the physical-chemical properties were analyzed. Assays were carried out with ASA and 1-MCP targeting the control of anthracnose and maintenance of the fruit’s physical-chemical properties. The effect of ASA (20 mM; 20 min) on reducing lesion diameter occurred when applied before inoculation. Fruits treated with 1-MCP (300ppb) for 12 h showed a smaller lesion diameter than control. For the physical-chemical analysis, fruit treated with 1-MCP (200; 300 ppb; 12h) maintained fruit firmness, delayed fruit ripening and fruit fresh weight loss.
