It would work on your food plot, but its way more expensive than 41% glyphosate. The Avocet is intended for aquatic vegetation and may be formulated a little different, its 50%+ glyphosate, but around $40 bucks a quart. Generic 41% glyphosate is $40 bucks per 2.5 gallons or less, and will get the job done.

There's some online sources for cheap 41% gly if your area doesn't have reasonable prices. I'll be glad to list them, if you need it.
