Abstract

Paraquat (1,1′-dimethyl-4,4′-bipyridinium ion) killed nearly 100% of the wild garlic (Allium vineale L.) plants when applied in spring, but was less effective when applied in the fall. Treatment in the spring with paraquat consistently killed more wild garlic plants than treatments at any other date. Eradication of a wild garlic infestation was achieved after applications for three successive springs. Near eradication was achieved with two annual applications of 2,4-D [(2,4-dichlorophenoxy)acetic acid]. Among herbicides evaluated postemergence on wild garlic, mefluidide (N-[2,4-dimethyl-5-[[(trifluoromethyl)sulfonyl] amino] phenyl] acetamide}, oxyfluorfen [2-chloro-1-(3-ethoxy-4-nitrophenoxy)-4-(trifluoromethyl)benzene], bentazon [3-isopropyl-1H-2,1,3-benzothiadiazin-4(3H)-one 2,2-dioxide], asulam (methyl sulfanilylcarbamate), and picloram (4-amino-3,5,6-trichloropicolinic acid) were not effective for controlling wild garlic. Glyphosate [N-(phosphonomethyl)glycine] and a mixture of cyperquat (1-methyl-4-phenylpyridinium) and 2,4-D ester reduced wild garlic populations by over 60%.
