During this work we detected 5 species of pathogenic fungi that damage seedlings and saplings of the Tiang-Shang spruce fir, which cause a perceptible damage to the coniferous nurseries of Northern Kyrgyzstan and require activities to protect the woods. The biological activity of Streptomyces metabolites for raising the resistance of seedlings to phytopathogenic fungi was tested in laboratory and field conditions during three seasons. In order to evaluate the biological activity of Streptomyces preparations as biological agents, we have soaked the seeds in the suspension of Streptomyces metabo ...Daha fazlası
