Abstract:
One strain with significant antagonistic effect against Colletotrichum capsici was obtained by plate-pairing method from the soil samples of healthy pepper rhizosphere in high incidence of pepper anthracnose fields in Zunyi area of Guizhou province.The results showed that the strain was finally identified as Bacillus velezensis by morphological,physiological and biochemical characteristics,a phylogenetic tree was built combined with 16S rDNA, gyrA gene sequence analysis results.The strain could produce biocontrol-related enzymes such as protease,cellulase,siderophore and phosphatase.It also had strong antifungal activity against 5 important plant pathogenic fungus such as Alternaria alternata, Phytophthora nicotianae,Phomopsis sp.,Sclerotinia sclerotiorum and Magnaporthe oryzae.This strain could be further studied and developed as biocontrol agents.Keywords:Bacillus;biological control;pepper anthracnose
