Description

 

Tenacity Herbicide works by inhibiting an enzyme that is essential to chlorophyll production and photosynthesis, allowing light energy to break down the chlorophyll and, as a result, turning weeds white within five to seven days after  application. This is normal and the white color is a sign that the product is working.

 

Occasionally, you may see white tips on desirable turf grass, but this is a temporary symptom and these white tips will eventually be mowed off. Tenacity Herbicide by Syngenta offers pre- and post-emergent control of more than 46 broadleaf weed and grass species, including crabgrass, ground ivy, yellow foxtail, yellow nutsedge and unwanted bentgrass.

 

Tenacity can be used at seeding to reduce weed competition so new turf can establish faster. Tenacity is the only residential-approved herbicide that selectively removes both nimblewill and bentgrass. Plus, it controls Crabgrass, Windmill grass, Clover, Ground ivy, Goosegrass, Yellow foxtail, Yellow nutsedge, Oxalis and more.

 

Key Features:

 

  • Weeds controlled include crabgrass, ground ivy, yellow foxtail, yellow nutsedge and nimblewill. It also controls unwanted bentgrass.
  • Provides post-emergent control of tough-to-control weeds.
  • Controls weeds at seeding reducing weed competition.
  • Prevents and controls crabgrass pre or post up to four tillers
  • Eliminates weeds at seeding so new grass can flourish.
  • We recommend mixing with Daisy J&M's 90/10 Surfactant for best results! (Follow the label's instructions).

Question asked: Will it kill quackgrass?
19-07-2026

No, Tenacity Herbicide is not labeled to control quackgrass. While it may cause temporary whitening or suppression, it is not considered an effective treatment for established quackgrass.If the quackgrass is growing in landscape beds, fence lines, driveways, or other areas where you do not want any vegetation, Home & Garden Supply carries Roundup ProMax Herbicide, which is labeled for quackgrass control. Because quackgrass spreads by underground rhizomes, repeat applications may be necessary for complete control.If the quackgrass is growing in a desirable lawn, there is no selective herbicide that will reliably kill quackgrass without also injuring or killing the turf. In those situations, carefully spot-treating with a glyphosate product such as Roundup ProMax is the most effective option. Read and follow the product label before use.

Question asked: Can I spray it on my Bermuda grass now in the middle of July to Control nut sage, and not kill my Bermuda?
17-07-2026

Home & Garden Supply carries products such as SedgeHammer that are labeled for yellow nutsedge control and are designed for use on established bermudagrass. Read and follow the product label before use.

10-07-2026

For established hybrid Bermuda lawns with severe Poa infestations, herbicides specifically labeled for use on bermudagrass are often a better choice.For Poa annua control in bermudagrass, Home & Garden Supply offers Celsius WG Postemergence Herbicide, which is labeled for use on established bermudagrass and provides excellent control of many broadleaf and grassy weeds while being safe for warm-season turf when used as directed.
