Killing weeds in Buffalo grass has always been a major concern for homeowners but there are several quality herbicides available to help combat infestation.
Which Herbicides Kill Weeds in Buffalo Lawn?
Today there are more herbicide choices that are readily available to effectively kill weeds in Buffalo grasses. We just must be aware that we need to purchase a product that is clearly labeled as Safe for Use on Buffalo Grass.
If the product is not clearly labeled as safe for Buffalo grass, then a simple check on the label for the active ingredient in the herbicide can be done:
- MCPAand Bromoxynil-based herbicides are generally safe for use on Buffalo grass.
- Dicamba-based herbicides are never safe for use on Buffalo grass.
Buffalo-friendly Herbicides
The biggest family of weeds is called Broadleaf weeds.
The term ‘Broadleaf Weeds’ refers to characteristics which many weed types have in common. Many different weeds can fall into this category such as Bindii, Clover, Catsear, Dandelion and various others.
Because so many weed types fall into the category of Broadleaf weeds, these are the weeds we will first target with a Broadleaf Weed Killer designed for safe use on Buffalo grass.
An ideal Broadleaf Weed Killer is Indigo Duke 100WG 100gm , a post-emergent liquid herbicide for the control of certain broadleaf weeds (such as Bindii, Black Thistle, Catsear, Cotula, Cudweed, Guildford Grass, Medic, Mouse Ear Chickweed, Oxalis, White Clover and False Onion Weeds). Duke is safe for use on Buffalo grasses as well as Kikuyu and Couch. It can not be used on Zoysia grasses.
Indigo Duke can be applied using a spray kit, but be sure to read the label prior to application.

Repeat Applications of Lawn Herbicide
Some weeds can be quite robust, and therefore difficult to eradicate in a single spray. Other weed types will have masses of seeds already in the soil, and therefore will continue to produce more weeds, even though the last lot were killed.
If weeds re-emerge after spraying, or some weeds still remain alive, repeat the weed spraying program, outlined above, again in another 2 weeks.
Don’t spray weeds after mowing
As with all weed killers, never spray any herbicide on a lawn within a week of its last lawn mowing.
The open wounds created from mowing will quickly absorb any herbicide and will damage or kill any lawn type, not just Buffalo.
It’s also a great idea to never mow the lawn until one week after applying herbicides, this allows ample time for the weeds to absorb the herbicide before it is removed with lawn mowing.
