Potential of a soil-borne Streptomyces hygroscopicus for biocontrol of a anthracnose disease caused by Colletotrichum gloeosporioides in orchid
The aims of this study are to isolate the antagonist from rhizosphere soil and evaluate its potential for biocontrol of anthracnose disease in orchid. The potential microbial antagonist, designated SRA14, was isolate and identified as Streptomyces hygroscopicus. Cell-free culture filtrates of Strept...
