甘薯瘟是甘薯生产上的毁灭性病害,也是国内及本省的检疫对象。病菌主要通过病苗病薯传播,把好薯苗的检疫检验关,不让病苗传入无病区,就成为防治甘薯瘟的根本性措施。如何准确、快速、简便地鉴定病苗与无病苗,是当前生产上急待解决的问题。几年来我们通过试验和实践,初步找出四种的鉴定方法,其中以番茄苗接种测定法的准确性较大,要求的条件也不高,很有实用价值。
Sweet potato plague is a devastating disease in the production of sweet potato, but also the quarantine object in China and other provinces. Pathogens mainly through the disease seedlings of potato spread, the good potato seedling quarantine inspection, not to disease-free access to disease-free area, it has become the fundamental control of sweet potato blast. How accurate, rapid and easy identification of disease-free vaccine and vaccine-free, is the current production of urgent problems to be solved. Over the past few years we passed the test and practice, initially identified four kinds of identification methods, of which tomato seedling inoculation assay accuracy, the required conditions are not high, very practical value.
