白叶枯病(Xanthomonas oryzae)和条斑病(Xanthomonas oryzicola)是水稻上的两种重要细菌病害。这两种细菌性病害都可以由稻种传播。稻种非但可以带菌,并且可以传病。为了防止病区的扩大和新病区的出现,加强检疫工作是非常重要的。 检验水稻白叶枯病和条斑病,可分室内检验和田间检验。室内检验主要是确定稻种是否带菌和带菌的程度,可以采用种植检验和噬菌体检验的方法,以噬菌体检验更为可靠。室内检验需要一定的设备,工作量较大,同时目前所用的室内检验方法是否适用于带菌量极低的稻种,还有待在生产实践中考验。田间检验就是通过病害的普查,了解病害发生情况,确定无病田和无病区。这样非但可以解决当地的留种和换种的问题,并且为无病稻种的调运提供依 Xanthomonas oryzae and Xanthomonas oryzicola are two important bacterial diseases in rice. Both bacterial diseases can be transmitted by the rice species. Not only rice species can carry bacteria, and can be transmitted disease. In order to prevent the expansion of the ward and the emergence of new wards, it is very important to strengthen the quarantine work. Inspection of rice bacterial leaf blight and leaf spot can be divided into indoor and field tests. Indoor testing is mainly to determine the extent of rice carrying and carrying bacteria, you can use the planting test and phage test methods to phage test more reliable. Indoor inspection requires a certain amount of equipment, the workload is large, and at the same time whether the current indoor test method is suitable for very low amount of rice species, yet to be tested in production practice. Field inspection is through the census of the disease to understand the occurrence of disease, to identify disease-free and disease-free areas. This will not only solve the problem of local seed and seed replacement, but also provide basis for the transportation of disease-free rice
