一、病征炭疽病菌能侵染匍匐茎、叶柄、叶和顶尖等所有部位。尤其是草莓的匍匐茎更易遭受侵染,一般从落叶处,匍匐茎的折断处和根部侵染。一旦顶尖被侵染,整株萎蔫,造成青枯,而后枯死。如果把顶尖切开可看出,从顶尖的外部向内变褐,但导管不变褐。由于这一症状和疫病相似,用肉眼不容易区分。区分的方法是:取感病变褐最重的部分,用显微镜观察,能看到炭疽病的分生孢子,以此来区 First, the symptoms of anthrax bacteria can infect stolons, petioles, leaves and top all parts. In particular, stolons from strawberry are more susceptible to infection, usually from fallen leaves, stolons and roots. Once the top is infested, the whole plant wilting, resulting in withered, then dead. If you cut the top can be seen, from the top outside of the browning, but the catheter does not brown. Because of this symptom and disease similar, with the naked eye is not easy to distinguish.
