人参锈腐病是我国各人参产区均普遍发生严重的病害,特别是老产区更为严重。一般发病率在70%以上;造成减产损失达30%左右。严重地影响人参的产量与质量。在对人参锈腐病的药剂防治上,以前我们曾用过多种药剂进行筛选,五十年代筛选出氯化苦、四十年代筛选出多菌灵进行土壤消毒,具有防治效果。但由于氯化苦施用困难,药械缺乏,难以推广应用,在此基础上,我们又继续进行药剂筛选,于1980年,开始研究棉隆防治人参锈腐病,现将结果作一初报:
Ginseng rust is a common disease in China’s ginseng production areas, especially in the old producing areas. The general incidence of more than 70%; resulting in loss of up to 30% loss. Seriously affect the yield and quality of ginseng. On the prevention and treatment of ginseng rust on the pharmaceutical, we have used a variety of agents before the screening, screening fortified in the fifties chloropicrin, fortified in the forties for carbendazim soil disinfection, with control effect. However, due to the difficulty of applying chloropicrin and the lack of drugstores, it is difficult to popularize the application. On this basis, we continued to carry out drug screening. In 1980, we started to study the prevention and treatment of ginseng root rust by ginseng.
