物理方法:Muenscher(1955,Bean and Russo, 2003)建议使用人工移除,可用耙子把走茎耙除,或在接近地面的地方割除,或挖除。化学方法:根据 CCSER,人工去除匍匐茎(蔓生的一个分枝,会发芽产生新的植物;走茎)和现场喷洒 0.25% 绿草萣水溶液或1% 草甘膦水溶液,是目前使用有效的控制措施。据Bean and Russo(2003),最有效的化学控制是百草枯和果尔除草剂,其中含有的活性成分oxyflurfen。其它已被证明有效的化学物质是2,4-D,2,3,6~TBA和Fenuron。
地点特有的管理信息Rangitoto Is. (North Island) A draft plan was devised in 1995 that considered distribution, impact on the native vegetation, and efficiency of propagule dispersal of the 72 weed species in setting priorities for control. The result was a strategy with a top priority of controlling around 20 species that had the potential to drastically alter the natural vegetation, but still had very limited populations. Perwinkle Vinca major came under this catergory. The weed management plan has evolved over five years with improving control techniques, new herbicides, new weed finds, and better mapping and relocation systems. Field surveys were conducted over key sites to indicate invasive species distributions. The Rangitoto weed team worked in groups of three to five, systematically searching and controlling each plot side by side in a line. One end person followes a plot boundary and the other end person reels out biodegradable cotton from a hip chain, the cotton line indicating the position of the next swath. For each plot the amounts of control time and herbicide used on each species is recorded. Comparison of these data from year to year, when the same method is used, indicates the progressive reduction of each weed. Chemical control is necessary on Rangitoto simply because digging weeds out is impossible over most of the island. A range of control trials were carried out in an effort to find effective herbicides and application methods. These included foliar spraying, painting the trunks with herbicide, (sometimes chipping the bark off first), and felling the weeds and painting the stumps. The trials initially involved replications of treated individuals and sites, and are now incorporated into the general control plan as we continue to refine the successful methods. The current (2002) status of periwinkle Vinca major is that it has been controlled to zero density. Rangitoto Is. (North Island) In 1995, a weed control programme was initiated on Rangitoto Island, with 72 weed species identified. These were split into three priority classes, each with a management objective. The long term aim for this species is control to zero density (no adult plants).
