Multiplex selection strategy was investigated in this study for screening the antagonistic isolates of Colletotrichum musae and assessing their potential ability to control banana anthracnose. Out of the primarily screened 997 isolates,280 antagonists were found out. Among these antagonists,20 isolates with higher suppression ability were chosen for multiplex selection using three screening methods( inhibition on mycelial growth,spore germination and lesion extension). In the next screening tests,20 antagon...
