Yes, Bonide Grass Beater Over-The-Top Grass Killer Concentrate is safe to apply over vinca minor. If a surfactant is used with this product, do not apply when temperatures are over 85 degrees to avoid injury. NOTE: This item has been discontinued by the manufacturer. Please see Bonide Grass Beater II Over-The-Top Grass Killer as a replacement. Per the Bonide Over the Top Grass Killer product label, adding an oil concentrate may help control weedy grasses however you will want to take the same precautions regarding applications with temperatures above 85 degrees. Please view page 6 off the product label for recommended rates and information.
