番茄营养丰富,生熟两用,深受城乡人民的喜爱,栽植面积逐年扩大。近年来花叶病毒病普遍发生,轻度年份发病率5—7％,局部地块达到30—40％;流行年份,一些地块发病率达75％以上。尤其靠近市郊的老菜区,有的田块常因此病绝收,严重影响了番茄生产。花叶病毒病是蔬菜生产中必须防治的主要病害之一。为大面积抑制番茄花叶病毒病提供科学依据和寻求较为有效的药物防治方法,于1983年春,配合中国农科院,采用“5406”
Tomato nutritious, raw and cooked, loved by urban and rural people, planting area expanded year by year. In recent years, mosaic virus disease occurs generally, the incidence of mild years 5-7%, local land 30-40%; popular year, the incidence of some plots of more than 75%. Especially close to the suburbs of the old vegetable area, some fields are often so ill off the harvest, seriously affecting the tomato production. Mosaic virus disease is one of the main diseases that must be controlled in vegetable production. In order to provide a scientific basis for large-scale suppression of tomato mosaic virus disease and seek more effective drug control methods, in the spring of 1983, with the Chinese Academy of Agricultural Sciences, using “5406”
