About the Webinar

Weeds in the organic pasture can reduce the quantity and the stand life of desirable forage plants. These unwanted plants can be more aggressive than existing or desired forage species and compete for light, water, and nutrients. Weeds may also diminish the quality and palatability of the forage available for livestock grazing, and certain weed species are potentially poisonous to grazing animals. In this webinar, Dr. Sid Bosworth will address several approaches to organic weed management, including weed species identification and their lifecycles.
