Rated 5 out of 5 by from I love this weed and grass killer I bought this in hopes I could gain weed and grass control and boy did I get it! This stuff goes a long way and kills everything it touched. So well I was scared to use it close to my trees! I used it in South Texas and followed the directions. I did not change the concentration!

Rated 5 out of 5 by from Very strong, Great for foodplots. Used 52 ounces in a 20 gallon sprayer an results were phenomenal. Much more potent than generic. Well worth the cost.

Is it the amount you spray per acre that will hurt costal? Agent said to spray 10 to 12 oz per acre

Asked by: jettex
I would be afraid of injury. But I also live in Tennessee and if the county agent recommends it he is more knowledgeable about his specific area.

How does this compare to Roundup Pro
