摘　　要：炭疽病是山药种植中的重要病害之一,一般可使山药减产20%~30%,严重者可达50%以上,更严重者绝收。温湿度适宜、连作、种薯资源不佳以及管理措施不当是引发炭疽病的主要原因。在防治炭疽病方面,应坚持"预防为主,早期防治"的理念,采取农业防治、物理防治和化学防治相结合的综合防治措施。Anthracnose is an important disease in the growth of Chinese yam. It can generally reduce the production of Chinese yam by 20% to 30%. In the case of severe cases,it can reduce the production more than 50%,the fields would be dead,the leaves fall,and even no harvest.The main causes of anthracnose are unsuitable temperature,growing the same crop in the same plot of land,bad growing resources and inappropriate management measures. About the prevention and control of anthracnose,we should adhere to the concept of "Focusing on prevention,early prevention and control",adopt comprehensive prevention and control measures that combine agricultural control,physical control and chemical control.
