Effect of the postharvest treatment with calcium chloride by the temperature differential method on the control of Colletotrichum gloeosporioides in guavas 'Branca de Kumagaii'.

Different calcium chloride (CaCl2.2H2O) concentrations were tested as postharvest treatments of guavas cv. 'Branca de Kumagaii' by the temperature differential method (fruits at 26 deg C and solution at 5 deg C by 2 hours) in order to study its effect on control of anthracnose decay caused by Colletotrichum gloeosporioides [Glomerella cingulata]. It was shown that calcium chloride stimulated the development of this fungus up to a certain concentration, above that, there was an inhibitory effect. Trials in vitro with 3 pathogenic strains confirmed the results observed in inoculated fruits.
