Lawn Weeds

Question

Hi there, What selective lawn weed killer can be used to eradicate (NOT control) Kikuyu grass (Pennisetum clandestinum) and Bermuda grass / wire grass please? Thank you Regards Jenny

Answer 1

Since you say "selective," I understand then that you cannot use a product like glyphosate or solarization because you aren't killing out an entire section. The article below says if your lawn is more than 40 percent kikuyugrass, you should just let kikuyugrass be your primary grass. Using a selective postemergent herbicide repeatedly plus spot selections with glyphosate are suggested.

Chemical warfare for Bermudagrass is also recommended.
