摘　　要：目前我国平菇和双孢蘑菇的年产量分别为248.8万t和133.0万t,在我国食用菌产业中居第一和第三位。随着周年生产的实行和栽培规模的日益扩大,平菇和双孢蘑菇的细菌性褐斑病也日益严重。子实体被感染后,菌盖表面出现圆形或椭圆形褐色凹陷斑,在潮湿条件下,尤其是菌盖表面有水膜时,该病最容易发生。细菌性褐斑病的病原菌是托拉氏假单胞菌Pseudomonas tolaasii,主要致病因子是托拉氏毒素(tolaasin)。该文作者从病原菌研究、致病机制和防治等几个方面对平菇和双孢蘑菇褐斑病进行了综述。The oyster mushroom and button mushroom are important cultivated edible fungi, and the yields of them are 2 488 and 1 330 thousand tons respectively per year in China. The bacterial brown blotch disease deteriorated and caused heavily economic loss when the cultivation scale was enlarged with year-round technology during last several years. The typical symptoms were that there were superficial brown lesions on pileus. The pathogen factor is tolaasin produced by P. tolaasii. The review presents recent studies about P. tolaasii, disease mechanism and control strategies.
