Effects of chitinolytic actinomycetes on Fusarium oxysporumf.sp.vasinfectum and Verticillium dahliae

Zong Zhaofeng

Abstract

The antagonistic effects and the chitinolytic ablity of the 58 isolates of the actinomyces were tested in vitro and 2 selected isolates F104 and F105 with chitinolytic ablity were screen for suppression of F.oxysporum f.sp.vasinfectum and V.dahliae.The mycelium of V.dahliae growth malformed in PDA diffusion test with the culture filtration of isolates F104 and F105.An effective control result to F.oxysporum f.sp.vasinfectum and V.dahliae were obtained when pre-inoculation of cotton seedling with isolates F104 and F105 in greenhouse.
