花生叶斑病的生物防治 从叶片、土壤及其他生境分离到几种非病原性菌。鉴定了这些非病原菌对花生叶斑病病原菌C.arachidicla和C.personatum的拮抗活性。筛选确认Bacilius thuringiensis 和 Pseudomonas cepacia对控制叶片病原菌有应用潜力。在实验室内测定,它们完全控制了病原真菌。小面积的田间试验防效达70％。对花生叶片每隔14天喷施一次净化制济较之未净化的菌剂防效更为明显。菌剂中含 Biological control of peanut leaf spot Several non-pathogenic bacteria were isolated from leaves, soil and other habitats. The antagonistic activity of these non-pathogenic bacteria against C.arachidicla and C.personatum, a pathogen of peanut leaf spot, was identified. Screening confirmed that Bacilius thuringiensis and Pseudomonas cepacia have potential applications in controlling leaf-pathogen pathogens. Measured in the laboratory, they completely control the pathogenic fungi. Small-area field trials control up to 70%. Spraying peanut leaves once every 14 days is more obvious than using unpurified agents. In the agent
