Top 5 dandelion killer

TZone SE Broadleaf Herbicide

According to my research, TZone may be the best dandelion killer on the market. As active ingredients here we have 2,4-D, Dicamba, and Triclopyr plus in addition to these ingredients, TZone contains sulfentrazone for a powerful 4-way weed killer. Sulfentrazone combos provide speedy and effective results in killing weeds and control against many tough broadleaf weeds, including dandelion, clover, nutsedge, and spurge.

Pros and cons


Works without a different non-ionic surfactant

Kills dandelions and other stubborn broadleaf weeds

Rainfast within 3 hours after application


Not available in all states

Restricted to licensed applicators

Mix rates and application tips

  • Cool-season grasses: Mix 1.2 – 1.5 oz. per gallon of water for around 1,000 sq. ft. coverage.
  • Warm-season grasses: Mix 0.73 – 0.83 oz. per gallon of water for around 1,000 sq. ft. coverage.
  • Avoid mowing two days before or two days after application.
  • You can repeat the application after 20-30 days after the initial application.

Speedzone EW Broadleaf Herbicide for Turf

Speedzone EW broadleaf is a well-known dandelion killer and is on this list with good reason. It is an excellent four-way selective herbicide that works on leaf tissue and roots. In addition to 2,4-D, Mecoprop-p, and Dicamba, Speedzone also contains carfentrazone for quickly visible results on ~100 grassy and broadleaf weeds, making it one of the best dandelion killers. A commonly used all-around broadleaf weed killer for lawns.

Pros and cons


Results within a few hours of application

Complete weed control in 7 days


Not safe for all warm-season grasses

Speedzone EW mixing rates

  • Mix 1.1 – 1.8 oz. in up to 5 gallons of water.

Tenacity Herbicide

Tenacity Herbicide can be used as a selective post-emergent weed killer and pre-emergent herbicide as well. The main active ingredient here is Mesotrione which kills weeds by inhibiting photosynthesis in the targeted plants by stopping dandelion growth and leaving the plant looking bleached white as they die off.

If you mix Tenacity Herbicide with the above-mentioned Speedzone you will get an extremely effective killer for all the existing weeds like dandelion, clover, and crabgrass that ruin your lawn.

Pros and cons


Controls over 40 grassy and broadleaf weeds besides dandelions

1/2 teaspoon is enough for a gallon of water

At the time of seeding or overseeding can be used as a pre-emergent


For best results requires mixing with a non-ionic surfactant (NIS)

Tenacity Herbicide mixing rates

  • 1/2 teaspoon per gallon
  • 1 1/2 teaspoon of NIS

Drive XLR8 Herbicide

Extremely powerful weed and dandelion killer. XLR8 is another good option for eradicating dandelions because quinclorac, an active ingredient, is probably the best dandelion and broadleaf weed killer.

Combined with TZone (number one on our list) you will get an ultimate herbicide combo for killing a number of weeds including dandelions.

Pros and cons


It is faster and more effective than a generic quinclorac

Is rainfast within an hour after the application has dried


Need to be mixed with (MSO) methylated seed oil for best results

Cannot be used on: St. Augustine, Centipede, Bahiagrass, Bentgrass or Dichondra

Drive XLR8 mixing rates

  • 1.45 fl oz per gallon of water (per 1,000 sq. ft.)
  • Mix 0.55 oz. of MSO for better effectiveness

Ortho Weed B Gon

The Ortho Weed B Gon is a ready-to-use (RTU) dandelion killer and comes with a hose-end sprayer. Just attach a garden hose to the bottle, turn the water on and spray. It is often found at local hardware and big box stores.

Pros and cons


Big coverage. 32 oz. treats 8,000 to 16,000 total sq. ft.
