    Q
    Can Killzall Weed and Grass Killer - 41% Glyphosate be used to kill Crepe Myrtle by applying to cut branches and new sprouts? Can this be used to kill wild violets? Do I need a surfactant?
    A

    Killzall Weed and Grass Killer - 41% Glyphosate is a non-selective post-emergent, herbicide which already includes a surfactant, and will provide control for most annual and perennial weeds, brush, and grasses - including violets.  However, for your crepe myrtle suckers, you may consider using Sucker Punch Ready To Use, which is specially labeled for use on ornamental trees and other woody plants and stops sprouting suckers from pruning cuts and roots of ornamental trees and other types of woody plants.
