Unfortunately, privet is going to be difficult to kill and can take repeat applications to new growth for some time. Glyphosate and triclopyr are the two most effective chemicals to prevent the re-growth of privet hedges. For young Privet, foliar applications with Eraser 41% Weed Killer Herbicide can be applied at the rate of 2.5 fl oz (5 Tbs) per gallon of water spraying the foliage to wet but not to the point of run off. Good spray coverage over the entire plant is very important as privet shrubs sprayed only on the sides will not be completely killed. The optimal timing for glyphosate treatment is late fall to early winter (November through early January) when day temperatures are mild. For established privet, we would recommend cut stump treatments where you would cut the stump down just above the ground and then immediately apply a brush killer such as Fertilome Brush Killer with a paintbrush (or full strength) onto the stump. If the privet has an open, tree-like form, cut off the side limbs first and then cut the main truck as close as possible to the ground. If it is growing as a compact shrub, cut it at the base and then drag the whole plant away as one piece If the privet is taller than 6 to 8 feet, consider using other methods such as brush mulching, basal bark, or cut stump treatment with a 41% Glyphosate + Surfactant or Triclopyr herbcide is suggested. Please review this article by Alabama A&M & Auburn University Extension Office that has some great information on alternative methods for treating Privet.
