Read Full Answer »Tordon RTU Spray is not labeled for Walnut Trees therefore we cannot confirm if it would be effective in killing the tree. Black Walnut tree roots can spread out 50-80ft from the tree and are known for resprouting. The most recommended treatment is to cut the stump as low to the ground as possible and apply a product with the active ingredient Glyphosate directly to the freshly cut stump. Direct stump treatments is going to be your best option and will take several months and maybe longer since this tree is so old. Roundup QuickPRO has Diquat as 1 of the 2 ingredients works for a faster knockdown and absorbs throughout the root system better. Drilling into the stump is also sometimes done for the herbcide to absorb quicker into the tree. -
Asked by Stuart from Port Angeles, Wa09/30/2022QTordon RTU Specialty Herbicide application to new shoots and water sprouts?
I found your product weeks AFTER I paid to have a large steep area (former railroad bed cut) trimmed of Maples and other woody brush. It's early Fall here in the PNW. What now? I cannot access all the cut stumps on this steep hillside, made even more treacherous now by the “Chop,spread and scatter” method employed that left downed saplings and branches everywhere. Can I spray this product on new tender growth in the Spring to control new growth? These nuisance, non-native trees grow up to block our gorgeous view of the Puget Sound every 5 years or so. Thanks!ATordon RTU Specialty Herbicide is best applied to fresh cut stumps, injected into the trees or a frill or girdle treatment as directed on the product label.
