    I know the classic "Threeway" type herbicides all control it. Repeat treatments are mandatory but do work. The below grong bulbs are a virtual energy plant & won't receive a lethal dose of herbicide on the first spray. Don't wait too long to treat either. Most of the LCO's in this area don't spray any herbs til it's warm enough for broad-spectrum results. This is good practice if we only target clover & dandelions, but that's too late for Wild Onions/Garlic.
    Take a look & see if this is what you're after.

    Add pelitized lime in March and crushed lime in the fall in Nov. Lime takes acid out of the ground and adds "PH". Also helps keep other weeds away

    Down here in Alabama the info that I have from Auburn Univ. says to treat in Nov (with 2-4-D or the Threeway chemicals) and then again in Feb. and repeat for 3 consecutive years. Might want to check with your local extension service for the exact times for your area.

    My partner and I do a mix tank of pre-M and 3 way ester. It seems to have knocked it back pretty good. I also like to mow the turf and normally that is the end of it.

    Although wild onion and garlic are unique because of the bulb type structure, any braodleaf herbicide for the most part will work.
    2-4,D, MCPP, Dicamba or any others will do just fine. 3 way and trimec are usually just combinations of these products. I have suggested good old scotts weed and feed type products to homeowners who come in the store and want to treat without spraying.
