Please let us know if you need a recommendation for an alternate product.

Tordon RTU Specialty Herbicide is labeled to target the following woody plants: ailanthus, alder, aspen, birch, cedar, cherry, dogwood, elm, firs, green ash, gum, hawthorn, hickory, hornbeam, maples, oaks, pecan, persimmon, serviceberry, sourwood and sweetbay. It does not specifically state Hackberry-Silver Maple Saplings on the label, however it has Maples in general in trees covered. If the root system is hearty, you will want to cut the saplings down as low to the ground and you can get them. Once cut, immediately apply the brush killer either by spraying it on, or paint it on undiluted. Please let us know if you have any other questions.
Tordon RTU Specialty Herbicide should not be applied to commercial or residential lawns or near ornamental trees and shrubs.

You can try something like RoundUp QuikPro applied to the cut stump but if they are large trees it might be best to contact a tree removal company. You would need to wait 2 weeks before removing the stump.
