Inhibitory influence of inorganic salts on banana postharvest pathogens and preliminary application to control crown rotLasiodiplodia theobromae, Thielaviopsis paradoxa, Colletotrichum musae, C. gloeosporioides, Fusarium verticillioides, and F. oxysporumwere screened in vitro for sensitivity to Na2CO3, NaHCO3, CaCl2, NaCl, and NaClO. The spore germination of all pathogens was completely inhibited by Na2CO3 4 g/l, NaClO 5 g/l, and NaHCO3, CaCl2, and NaCl 6g/l each. Dipping the bananas for 10–15 min in these concentrations reduced the incidence of crown rot (compared with the untreated fruits) 17 days after harvest in fruits treated with NaClO by 67%, with NaHCO3 by 62%, with NaCl by 38%, and with CaCl2 by 33%. Na2CO3-treated fruits had the same incidence of crown rot as untreated fruits.
