一、用弱毒病毒疫苗防治西红柿花叶病毒花叶病毒(TMV)是西红柿的主要病害之一,特别是温室栽培由于受到连作的影响,花叶病危害遍及全国。过去虽然以种子和土壤消毒避免一些接触传染,但由于其毒性很强,没找到有效的防治方法。早以发现植物被某一种病毒感染,对其近缘病毒有发生免疫的现象,把这种现象叫做干扰作用,利用这种原理,在西红柿尚未感染野生强毒病毒时,接种弱病毒疫苗防治花叶病毒病是很有效的。
First, the use of attenuated virus vaccine control tomato mosaic virus Mosaic virus (TMV) is one of the main diseases of tomatoes, especially in greenhouse cultivation due to continuous cropping affect the mosaic disease hazards throughout the country. In the past, although some contact infections were avoided by seed and soil disinfection, effective prevention and treatment methods were not found because of their high toxicity. As early as the discovery of plants infected by a certain virus, the occurrence of its neighboring virus immune phenomenon, this phenomenon is called interference, the use of this principle, in the tomato has not yet infected with wild virulent virus, the vaccination against the virus vaccine Mosaic virus disease is very effective.
