Product Q&A

Answer:

Roundup Pro Concentrate and Roundup Pro Max are both Group 9 Herbicides and both contain their own surfactant along with the glyphosate. They are essentially the same product with a small difference in the amount of active ingredient (50.2% to 48.7%) and they come in different size containers. Both are labeled for perennial weeds like Canada Thistle and would be effective in killing the weed.
