试验表明,人参锈腐病菌[Cylindrocarpon destructans(Zinss) Scholten]具有潜伏侵染的特性。在1-5年生外观无病斑的参根内,是普遍带有潜伏的锈腐病菌,参根的带菌率和潜伏侵染点值,随根龄的增长而增高。3年生人参的根系中,主根对锈腐病菌的感染率最高。春季移栽3年生参根、盆栽鹿粪和50%禾穗胺600倍侵根,均对该病菌有一定的防治效果。

Studies on root rot caused by Cylindrocarpon destructans (Zinss)Scholten in ginseng revealed that latent infection from this fungus was found in healthy ginseng root.In the 1-5-year-old roots,root rot percentage and latent infection sites increased with the age.The root system of 3-year-old seedling could be all infected,especially the tap root.
In pot trials,deer feces amendment significantly reduced both the root rot percentage and the disease index of ginseng roots to 50% more than those of the chock.Transplanting 3-year ginseng seedling in spring,good results would be obtained in the control of root rot.
