    Roundup PowerMax 3 Herbicide Weed Killer - 51.2% Glyphosate - 2.5 Gallons

    Round up power max is absolutely excellent. This product burns down my food plot areas within a week to 14days providing the weather remains dry. It is extremely important to use 3 ounces per gallon of water to get the proper effect from the round up. Using this product on round up ready soybeans has diminished the weed competion throughout most of the summer.

    My experience in dealing with Keystone has been great. Wes, who worked with me and answered a lot of my questions, was extremely helpful and knowledgeable about the product that I ordered. The Triclopyr, although very expensive when applied to cut trees at a rate of one part to three, seems to have worked well so far and has helped me/us get rid of a very difficult tree to eradicate here in Hawaii. I would highly recommend this product. I thank Wes in particular for his help with providing me detailed info about this product and its application as well as applying any discounts available for my purchase and shipping costs. Many thanks to a job well done by Keystone and for advising me to use this Triclopyr tree killing solution.

    Cutrine Plus granular seems to have worked great. I treated a pond that livestock use and wade in to. No harm to any cattle, but the algae has yet to come to the surface. I treated before it was visible. Rainfall has been scarce and still no sign of algae!

    works well, we mix with arrow and pep oil and save time. We never loose any clover doing it this way.
