Abstract : Antagonistic microorganisms significantly reduced the incidence of leaf anthracnose disease (caused by Colletotrichum gloeosporioides [Glomerella cingulata]) on mango, and markedly increased the activities of polyphenol oxidase [catechol oxidase], phenylalanine ammonia-lyase and peroxidase in host leaves. The results indicate that the pathogen-suppressive substance(s) produced by the antagonistic microorganisms and the increase in enzyme activity in host leaves reduces disease severity.
