Chinese privet is one of the most invasive shrubs in the southeastern United States - frequently growing in dense thickets along roadsides, on rights of way and in forests. Now the journal Invasive Plant Science and Management has good news for land managers battling the shrub. Researchers say you can achieve great control with much less herbicide than typically used.
A team of scientists investigated a popular "cut and treat" technique that involves removing Chinese privet's dense foliage and applying glyphosate or triclopyr to control new shoots emerging from the root collar. During a multiyear study at two forested sites in Alabama, varying rates of glyphosate and triclopyr were applied to Chinese privet root stumps in the spring and in the fall to evaluate their relative effectiveness.
