Chemical Weed Control in Roadside Vegetation on Highway Right-of-Way

Experiments were conducted at six locations to determine methods for eliminating or controlling existing weeds on highway rights-of-way prior to planting, and preventing weed infestations after planting, without injuring or interfering with normal growth and development of desirable plant material.

Four experiments were conducted to determine herbicide programs for eliminating weeds in natural stands of kinnikinnick (Arctostaphylos uva-ursi [L.] Sprang) and salal (Gaultheria shallon Pursh.) on highway rights-of-way, permitting these plants to form solid covers of uniform attractive vegetation.
