Cuscuta campestris Yuncker is a potential holoparasite used for biological control.To understand the efficacy and safety of Cuscuta campestris Yuncker in preventing and controlling Mikania micrantha H.B.K.The dodder C.campestris Yuncker were placed to 1 218 hm2 area of M.micrantha H.B.K in 7 forest parks of Shenzhen and carried out filed monitoring.The results showed that the area of M.micrantha was about 792 hm2(coverage rate 53%-73%),the rate of parasitism was 44%-87%,and the area of M.micrantha was decreased by 426 hm2 after putting in the field of C.campestrisYuncker.The number of other plants affected by C.campestris was 153 species,belonging to 43 families from 109 genera.There are 15 species of phants were in contact with M.micrantha without harm(Grade 0).138 species of plants were in contact with M.micrantha and affected other phants(GradeⅠ-Ⅲ)without a deadly parasite plant except for M.micrantha.All results provided a scientific basis for generalizability of the control of M.micranthain large area.
