Abstract
An antagonistic actinomyces strain A03 was isolated from vegetable soil in suburb of Beijing. In order to evaluate scientifically the applied potential of the strain for the biocontrol of plant diseases, the fungistatic activity of A03 was determined by confronting incubation on PDA plates and control test to the potted plants in greenhouse, and the taxonomic identification of the strain was carried out with morphologi- cal, chemical and molecular methods. The results showed that the strain A03 displayed a broad-spectrum inhibiting activity to all the 15 plant pathogenic fungi tested. Especially, the inhibition zones out to the width of 11.0-12.0 mm were presented by the strain against 4 ones of the pathogens, Botrytis cinerea, Alternaria solani, Rhizoctonia cerealis and Pythium aphanidermatum. The biocontrol effect of strain A03 to gray molds of pepper and tomato reached respectively 84.97% and 79.51% in greenhouse. According to the characteristics of morphological, cultural, physiological and biochemical, chemical components of cell wall, as well as 16S rDNA sequence, the strain A03 was identified as Streptomyces hygroscopicus.
