Not "agricultural grade" just full strength. Most home & garden versions of ag chemicals are basically deluted from original.
You have to have an Agricultural License to purchase it. The farmer buys it by the 330 gallon tote.
I paid $20 for a gallon milk jug full. 2 teaspoons to a gallon of water will kill any weeds I have put it on for at least 1/2 to 2/3 of the summer.
The stuff in the stores is junk compared to this.
