The Use of Domestic Goats and Vinegar as Municipal Weed Control Alternatives

摘要

This article presents the results of a two year pilot case study of alternative weed control in a northern Canadian community. Investigators tested the efficacy of acetic acid (vinegar) and a domestic herbivore (goats) as invasive weed control alternatives to the use of commercial herbicides in a north central British Columbian municipal setting. Results were positive for using an 8% concentration of vinegar as a control for Canada thistle (Cirsium arvense (L.) scop.), although these results were significant only in the second year of applications. Domestic goats demonstrated significant interest in thistle, as well as hawkweed, (Hieracium spp.), two species of horsetail (Equisetum arvense and Equi-setum pratense), oxeye daisies (Leucanthemum vulgare), and the common dandelion (Taraxacum officinale). Cost estimates suggest that over a five year period, both methods are as cost effective as single application herbicides, while posing fewer concerns over impacts on human and ecosystem health. Both are simple solutions easily implemented, with some planning, even by small municipalities and communities.
