For the control of wild garlic in Missouri in comparison with 2,4-dichlorophenoxyacetic acid (2,4-D) during 1954–1960, 3-amino-1,2,4-triazole (amitrole), sodium 2,2-dichloropropionate (dalapon), maleic hydrazide (MH), 2,3,6-trichlorophenylacetic acid (fenac) and 2,3,6-trichlorobenzoic acid (2,3,6-TBA) were effective. 2,3,6-TBA alone was more effective than 2,4-D. The toxicity of 2,3,6-TBA was increased by addition of a wetting agent. Heavy spot treatments of wild garlic with 2,3,6-TBA killed the established plants, but did not eradicate wild garlic because of sprouting of dormant bulbs.
