Does anyone have any suggestions for killing wild onions? I have tried many things and they just get worse. Digging them up, works I know, but I have a lot of them in my 2 acre lot.

Wild onions, though not a horse's best friend does have it's uses besides using tops like chives. They are not liked by most fire ants and they put nutrients in soil. Tilling and then adding Round Up works.

Par III. You can usually purchase this or something like it at your local feed store. Do not waste your time with Weed-B-Gone because the active ingredients are such a small percentage of the product that you will have to buy it in bulk (which is the point). 2-4,D is what you are looking for. Your yard will look like a golf course in no time.
Both wild onions and wild garlic prefer to grow in acidic soils that are low in organic matter. Applying lime to the soil will increase the organic matter and change the pH to levels that are inhospitable to wild alliums. Be careful to not apply lime near acid-loving plants such as rhododendrons or azaleas.
If you are not opposed to using chemical herbicides, look for a post-emergent herbicide that can be applied to the wild garlic or wild onions. Do not use a preemergent herbicide as this will have no effect on the underground bulbs. Before applying an herbicide to the wild alliums, it is helpful to mow the plants to rough up their foliage and increase their ability to absorb the herbicide. Once the herbicide has been applied, do not mow again for at least two weeks

This works fast, safe, and cheap. Get gallons of white vinegar, and give each clump of wild onions a small drink. Too much will just "run off" and be wasted.
Does anyone know the best chemical spray to use on wild onions or wild garlic? I used IMAGE and it did not seem to work, I even doubled the mixing instructions.
Does anyone know how to get rid of wild onions in lawns without having to dig them up? That's not practical. The space is about 3/4- 1 acre, riding lawnmower doesn't kill them and garden poison doesn't either.
