| Abstract: | With Colletotrichum capsici as indicator,9 antagonistic actinomyces were screened from tea garden soil by plate confrontation method and were named as F1,F2,F3,F5,F8,F11,F15,F57 and F59.They had a broad-spectrum antimicrobial activity and also showed better inhibiting effect on Phyllosticta theafolia Hara,Phytophthora var.nicotianae,Rhizoctonia solani,Pythium aphanidermatum.Fermentation broth of strains F1,F2 and F3 had notable inhibiting effect on Phytophthora nicotianae,the inhibition rates were 78.8%,61.... |
