Atticus Torocity Herbicide (8oz) - (Compare to Tenacity) - Mesotrione Concentrate - Selective Weed Killer for Lawns and Turf Grasses - Pre and Post Emergent Control
- TRUSTED PERFORMER: Torocity contains 40.0% mesotrione; the same active ingredient as the leading brand, Tenacity. For more than 20 years, mesotrione has been the trusted choice for effective weed control in newly seeded areas as well as established turf.
- FLEXIBLE APPLICATION TIMING: This double-hitter herbicide allows timing forgiveness with both pre- and post-emerge activity. Compared to pre-emerge only herbicides, Torocity widens the application window so you can stop new weeds before they start and take down the weeds you already have.
- BROAD-SPECTRUM WEED CONTROL: Torocity delivers powerful control of many broadleaf and grassy weeds, including crabgrass, ground ivy, clover, oxalis, and dandelion.
- IDEAL TURF RENOVATION PARTNER: Torocity is one of the few herbicides labeled for just-seeded Kentucky bluegrass, tall fescue, perennial ryegrass, and centipedegrass. Apply before seed germination to prevent weed competition and encourage new grass growth. Torocity may be used on new seedings, grass grown for sod, and established turf. Do NOT apply to Bentgrass, Zoysiagrass, and actively growing Bermudagrass. See label for complete list of tolerant turfgrass species.
- EASY-MEASURE TOOL INLCUDED: We took out the guesswork so you get the right rate – easily. Our pre-marked syringe highlights the exact amount of product needed per gallon of water. Torocity is activated by water, if rainfall doesn’t occur within 10 days of application, water the area with 0.15 inches of water.
Rank No. #3
Liquid Harvest Mesotrione - 8oz - Mesotrione Concentrate (Compare to Tenacity) - Pre and Post-Emergent Weed Killer for Lawn and Turf Grasses
