Research Results from BARC
Greenhouse and field research have been conducted at Beltsville,
Maryland, to determine the efficacy of vinegar for controlling weeds.
The results indicate that vinegar can kill several important weed
species at several growth stages. Vinegar at 10, 15 or 20 % acetic
acid concentration provided 80-100 percent kill of selected annual
weeds, including giant foxtail up to 3 inches in height, common
lambsquarters up to 5 inches, smooth pigweed up to 6 inches, and
velvetleaf up to 9 inches. Control of annual weeds with vinegar at the
5 % acetic acid concentration was variable. Canada thistle shoots were
highly susceptible with 100 percent kill by 5 % vinegar. However,
there was re-growth from Canada thistle roots.
