根结线虫Meloidogynespp.是植物根系专性内寄生物,是威胁农业生产的重要病原物,一般减产10%~20%,严重时可达75%以上[1]。目前生产中可供选择的杀线虫剂很少,生物防治是防治该病害的有效途径。链霉菌是一类重要的生防菌,能产生多种抗生素,其中阿维菌素已应用于防治根结线虫病,但
Root-knot nematode Meloidogynespp., An endophyte-specific endophyte, is an important pathogen threatening agricultural production. It generally reduces the yield by 10% to 20% and in severe cases up to 75% [1]. At present, there are few nematicides to choose from in the production, and biological control is an effective way to control the disease. Streptomyces is a kind of important biocontrol bacteria, can produce a variety of antibiotics, abamectin has been used to control root-knot nematode disease, but
