Control of anthracnose caused by Colletotrichum musae on Curcuma alismatifolia Gagnep. using antagonistic Bacillus spp.
Over 400 bacterial strains, isolated from leaf surfaces of Curcuma alismatifolia Gagnep. and hot springs in the Chiang Mai province of northern Thailand, were screened in vitro for antagonistic activity against Colletotrichum musae, an anthracnose fungus. Three isolates provided greater than 75% gro...
