Биологическая защита гороха и сои от корневых гнилей биопрепаратами на основе trichoderma [Articol]

Abstract

The results of the laboratory investigations of the influence of the biopreparations Gliocladin-SC and Trichodermin-SC on the pathogen fungi, which cause the pea and soybean root rots, are represented. The biopreparations effect has been determined by the double cultures method, diffusion in agar and by growing seeds on the agar plates, inoculated with suspension of the pathogens spores. The biopreparation activity was evaluated against pathogen fungi Sclerotinia sclerotiorum, Fusaruim oxysporum, F. sporotrichiella Bilai., F. solani, Fusarium sp., Rizoctonia solani. The biolpreparations demonstrate antifungal activity against the pathogen microorganisms, causative agents of the pea and soybean root rots. The biologically active substances which are presented in the biopreparation, inhibit the pathogen development, forming the sterile zones of the growth suppression on the agar plates.
