The best broadleaf weed killers for lawns in 2026, ranked by active ingredient effectiveness. Covers dandelion, clover, creeping charlie, plantain, and wild violet treatment.

Our Top Pick

Trimec Classic (three-way: 2,4-D + dicamba + MCPP) is the best all-around broadleaf herbicide for most lawn weeds. For tough weeds like creeping charlie and wild violet, Crossbow or triclopyr-based products are necessary.

Triclopyr 4EC (Triclopyr Ester)

How We Ranked These Products

We evaluated broadleaf herbicides based on active ingredient spectrum (how many weed species they kill), safety on cool-season lawn grasses, difficulty of application, speed of results, and cost per 1,000 square feet. Products are split into two tiers: general-purpose (kills common broadleaf weeds) and tough-weed formulas (for creeping charlie, wild violet, and other resistant species).

Every product listed here is selective, meaning it kills broadleaf weeds without harming bluegrass, fescue, or ryegrass when applied according to label directions. Always check the label for your specific grass type, especially if you have bermuda, zoysia, or St. Augustine.

How We Tested

Ranked by weed spectrum coverage, cool-season turf safety, application convenience, speed of visible results, and cost efficiency. Based on university extension research and 30+ years of field use. Prices verified April 2026.

Frequently Asked Questions

What is the best weed killer that won't kill grass?

Trimec Classic or any three-way herbicide (2,4-D + dicamba + MCPP) kills most broadleaf weeds without harming cool-season lawn grasses. For tough weeds like creeping charlie and wild violet, triclopyr is necessary. Always check the label for your specific grass species.

When should I spray broadleaf weeds?

Fall (October to November) is the most effective window. Perennial weeds are pulling nutrients to their roots for winter storage, carrying herbicide deep into the root system. Spring and summer applications work but require more follow-up. Avoid spraying during drought stress or above 90 degrees.

What's the difference between 2,4-D and triclopyr?

Both are broadleaf herbicides but triclopyr is stronger on tough, waxy-leaved weeds like creeping charlie and wild violet. 2,4-D is effective on most common weeds (dandelion, plantain, clover). Triclopyr costs more but penetrates waxy leaf coatings that shed 2,4-D.

Do I need a surfactant?

For standard weeds (dandelion, clover, plantain), a surfactant is helpful but not essential. For waxy-leaved weeds (wild violet, creeping charlie), a surfactant is necessary. It breaks the surface tension so herbicide sticks to and absorbs through the leaf coating instead of beading off.
