列当是新疆地区植物检疫对象之一。其寄主范围很广,涉及葫蔗科、茄科、豆科、菊科、十字花科及繖形花科多种栽培植物,尤以葫蘆科和茄科受害较重。据1960—1963年调查:五年中连作或断续三年种植的甜瓜,平均寄生率为31—54％,最高达100％。蕃茄平均寄生株率为13—18％,最高达37％。受害植株生长缓慢,产量低;所结甜瓜味淡而不甜,品质显著下降。
Column is one of the objects of plant quarantine in Xinjiang. Its host range is very wide, involving a large number of cabbage family, Solanaceae, Leguminosae, Asteraceae, Cruciferae and Umbelliferae cultivated plants, especially Cucurbitaceae and Solanaceae heavier victims. According to the survey from 1960 to 1963: melons planted three years in a row for five years or intermittently, the average parasitism rate is 31-54%, up to 100%. The average tomato parasitic plant rate of 13-18%, up to 37%. Affected plants grow slowly, yield is low; the melon tastes light but not sweet, the quality drops significantly.
