随着不同区域之间甘薯种薯和种苗的相互调运,导致茎线虫病的发生危害逐年加重,严重制约着甘薯产业化的健康持续发展。针对甘薯茎线虫病的发病条件、发病规律和传播途径,制定出农业防治和药剂防治相结合的综合防治技术,可有效地控制其危害,以此推动甘薯产业的发展。 With the inter-regional transfer of sweet potato seed and seedlings, leading to the occurrence of stem nematode disease increased year by year, seriously restricting the healthy and sustainable development of sweet potato industrialization. In view of the onset conditions, pathogenesis and transmission of sweetpotato stem nematode disease, we developed a comprehensive prevention and control technology combining agricultural prevention and control, which can effectively control the harm and promote the development of sweet potato industry.
