How Do I Get Rid of Green Kyllinga?

Cultural control is the best long term solution for weed control. Creating an environment where your grass thrives and out competes weeds makes for an easier life. Green kyllinga thrives in poorly drained soil. Proper drainage will greatly improve your lawn. Additionally, proper mowing heights will keep your grass in the best position to edge out weeds. 

We deal with a few grass types around Baton Rouge and New Orleans: St. Augustine, Centipedegrass, Zoysia, and Bermudagrass. Luckily, there are a lot of good options for chemical control in these grass types. Look for products containing any one of the following active ingredients: sulfosulfuron, imazaquin, sulfentrazone, halosulfuron, bentazon]. Read and follow the label for application instructions. Some herbicides take multiple applications. 

Ensuring proper drainage and following up with a control product will take care of your weed problem in no time.
