I used 48 oz Gramoxone and 1.5 pints Caparol. Killed about 1/2 of them. Anything that was branched out did not die. Others fried all but the bud and they are coming back out. But I used no oil and only 10 gpa, the minimum on the label. If I were you and use Gramoxone, I would use a minimum of 15 gpa.

We sprayed a little over 400 acres with 36 oz Ignite and 2 oz Canopy EX a week ago. So far, it looks like it's doing a good job, although not much on the wild garlic. We used 20 gpa. I've seen some that others sprayed before we did, and it's brown and crispy. One supplier is recommending 40 oz. and another says 32 oz is plenty. We split the difference and used the 36 oz rate.
