Barrier herbicide


5 year old buck +
My Dad sprayed Barrier instead of Roundup in a new food plot location. From what I am reading online, it looks like it kills everything like glyphosate but it also claims that nothing will grow for up to 12 months. The label also says that heavy rain will shorten the time it is effective.

I was going to plant wheat and clover in this location. If we disk the ground, will anything grow? Or, did he nuke the area so much we have to wait until next year?

I tried to teach him about generic roundup to save a few bucks. Did he buy the wrong stuff and screw up the ground?

I don't use herbicides much so I don't have any experience except for the occasional Gly application.
