Efftcts of phenols on growth and reproduction of Colletotrichum corda in latent infection

The tests on effects of tannin, resorcinol, catechol, chlorogenic acid and caffeine were conducted on spore germination, appressorium formation and sporulation of Colletotrichum musae from banana fruits and gloeosporioides from mango fruits in latent infection. The results show that these phenols are able to inhibit growth and development of C. musaeand C. gloeosporioidesat certain concentration. They are among the inhibiting factors of latent infection of these fungi in unripe fruits.
