Abstract:
Plant parasitic nematode could be controlled by antibotics effectively.It is well-known that actinomycetes should be able to produce antibiotics.At present，we had screened 5 strain actinomycetes，and tested their activity on soybean cyst nematode J2 by means of separate technique and intro-culture fermentation.Effects of secondary metabolites of actinomycetes on Heterodera glycines-J2 showed that: fermentation filtrates of strain C25-3 manifested the highest level of toxicity on J2，and the other strains also had been effective.The corrected mortality rate of J2 reached 95% by strain C25-3 at 4 diluted solution，and the other strains also reached beyond 60%.Activity of the strains C25-3，H-2 and C44 had never varied with different phenotype cyst nematodes J2 which came from Heilongjiang and Liaoning province，on the contrary，the strains C49 and H-4 displayed different level of toxicity.The phenotype cyst nematodes of Heilongjiang included race 3，race 4 and race 14，and that of Liaoning only included race 3.So we found some actinomycetes could produce broad spectrum antibiotics for different phenotype cyst nematodes and others were opposite in this research.
