为提高北部湾地区特色"红姑娘"甘薯产量和预防病毒病的为害,开展脱毒苗在不同发病程度区域繁育种苗预防病毒病效果试验.结果发现,种苗带病毒和重病区种植是病毒病发生率高的主要原因.防控方法主要有:统防统治,大面积喷药治虫,把带毒昆虫口密度降低,才能有效防治甘薯病毒病;凡是病区生产的甘薯不能作种用,也不能在病区繁育种苗.

In order to improve the yield and virus prevention technology for niche crop 'Hongguniang' sweet potato cultivation in the region of Beibuwan, Guangxi, we arrange related effectiveness trials of the virus-free sweet potato seedling propagation in many area which occurring different degree of virus infection for testing effects of prevention. The results show that seedlings with virus and cultivation in serious virus infection area are the main reason of high virus incidence. In order to effectively control sweet potato virus disease, we have to rely on as follows methods:prevention and controlling, spraying pesticides in a large area, and reduce in-fected insect population density. All kinds of sweet potatoes produced from virus infection area can not be used, nor breeding seed in the virus infection area.
