Best Weed Killer for Bermuda Grass (Tested Picks)
The herbicides that kill weeds in Bermuda without harming the turf — compared by ingredient, coverage, speed and value.
Bermuda is one of the most herbicide-tolerant lawns you can own — which means your options are wide, and the difference between products comes down to which weeds, how fast, and cost per thousand square feet. Here’s what actually works.
How We Picked
We compared active ingredients against the weeds Bermuda owners actually fight — crabgrass, dallisgrass, nutsedge, spurge and clover — and scored each product on selectivity (no Bermuda injury at labeled rates), speed of visible results, coverage cost, and ease of application for a homeowner without a commercial license.

Our verdict: For a typical quarter-acre lawn with seasonal weeds, Weed B Gon Plus Crabgrass is the practical winner. If you fight weeds all summer, treat a large lawn, or need to spray in Southern heat, Celsius pays for itself within two seasons.
When to Apply on Bermuda
Timing matters as much as product choice:
- Full green-up first — spraying half-dormant spring Bermuda causes injury and poor uptake. Wait until the lawn is uniformly green and growing.
- Under 90°F for 2,4-D-based products; Celsius is the exception for hot weather.
- Young weeds die easier — a 2-inch crabgrass seedling needs one pass; an August monster with tillers may shrug off three.
- No mowing 2 days before or after — the herbicide needs leaf surface to work.
Prevention Beats Spraying
The cheapest weed killer for Bermuda is Bermuda itself. Mowed low and often, fed a pound of nitrogen per thousand square feet per growing month, a Bermuda lawn forms a canopy so dense that weed seedlings never see daylight. Pair a spring pre-emergent with a healthy feeding schedule and most of the products above become a once-a-season spot treatment, not a monthly ritual.
Frequently Asked Questions
What weed killer is safe for Bermuda grass?
Bermuda tolerates most selective herbicides well: 3-way broadleaf mixes (2,4-D, dicamba, MCPP), quinclorac for crabgrass, and metsulfuron or Celsius for tough broadleaf and grassy weeds. Never use non-selective glyphosate on areas you want to keep.
When should I not spray Bermuda grass?
Skip herbicides during spring green-up (when the lawn is half-dormant and vulnerable) and during heat stress above 90°F. Both windows cause visible turf injury even from normally safe products.
Will Weed B Gon kill Bermuda grass?
No — Ortho Weed B Gon is a selective broadleaf herbicide and is labeled safe on established Bermuda at normal rates. The 'plus crabgrass' version with quinclorac is also Bermuda-safe.
What kills weeds and feeds Bermuda at the same time?
Weed-and-feed products combine fertilizer with broadleaf herbicide, but the timing compromise means both jobs are done at half quality. On Bermuda, you get better results applying herbicide when weeds are young and fertilizing after full green-up.
