Abstract

Endophytic actionmycetes No.37 was isolated from surface-sterilized tomato plant tissues.It had strong antifungal activity to Botrytis cinerea and other plant pathogens.The metabo-lic products of strain No.37 could strongly inhibit the mycelium growth and spore germination of Botrytis cinerea.The protective efficacy and therapeutic efficacy against Botrytis cinerea on pot tomato plants got to 89.7% and 80.3%,respectively.The effect of 10 times dilution against Botrytis cinerea was 84.1% in the field.
