经生物学、血清学测定,引起天津市卫青萝卜病毒病的毒源主要为TuMV,占67％。菜缢管蚜偏嗜十字花科蔬菜,是传播TuMV的主要介体,其寿命、繁殖力和迁飞受环境因素影响。病毒病的生态防治技术重点是控制蚜虫为害,方法为:地周种植韭菜、玉米隔离带;设银灰塑料条屏障,避开蚜虫迁飞高峰,适期(8月12日)播种;蚜虫传播期喷洒50％病毒1号油乳剂250倍。
By biological and serological tests, the main source of Tianjin Weiqing radish virus disease TuMV, accounting for 67%. Aphis gossypii, a herbicide of cruciferous vegetables, is the main mediator of TuMV transmission and its life span, fertility and migration are affected by environmental factors. The focus of ecological control of virus disease is to control aphid infestation. The method is as follows: planting chives and corn isolation zone in the periphery; setting a barrier of silver plastic strips to avoid the aphids migrating peak and sowing on the suitable period (August 12); aphid propagation period Spray 50% virus # 1 oil 250 times.
