蔬菜病毒病症状与有些非侵染性病害如缺素症、药害、遗传性或生理病害及类菌原体病害很相似,多表现为褪绿、花叶、变色、黄顶、巨芽或矮小等,一般菜农在田间不易区分,在实际生产中主要以外部症状的表现来识别.病毒病以预防为主,综合防治方法有:浸种处理;轮作换茬;大田生长期搞好传毒媒介虫源的防治;加强田间肥水管理,促进植株健康生长;使用植物生长调节剂提高植物体内抗病免疫能力;针对性的药剂防治,并结合根外追肥.

The symptoms of vegetable virus diseases are similar to some noninfectious diseases such as nutrients deficiency, phytotoxicity, genetic or physical diseases and mycoplasma-like organism diseases, and the symptoms are mostly show up as chlorisis, mosaic disease, discoloration, yellow top, huge bud and brachysm and so on, so it's difficult for farmers to identify vegetable virus diseases in the field. Vegetable virus diseases are mainly identified by the performance of external symptoms in the actual production. And the comprehensive prevention and control methods are as follows: seed soaking, crop rotation, controlling piercing and sucking pests during the field growth period, strengthening the fertilizer and water management in field to promote the healthy growth of plants, enhancing plants' disease-resistant immunity by using growth regulators, and using specific chemical prevention and control methods combined with top dressing.
