Atticus

Atticus Sertay Herbicide (1.25 oz) - Sulfosulfuron Weed Killer for Southern Lawns – Post Emergent Weed Control - Sedge, Nutsedge, Kyllinga

Free Shipping

Main Highlights

WEED CONTROL FORMULATED FOR SOUTHERN LAWNS: Sertay contains 75% sulfosulfuron; the same active ingredient as the Leading Brand, the top herbicide for grass, broadleaf, and sedge control in warm-season turf.
YOUR ANSWER TO SUMMER SEDGE: When you need weed control plus sedge takedown, turn to Sertay. This proven herbicide works on grassy and broadleaf weeds as well as on sedge, nutsedge, and kyllinga. Apply spring, summer, or fall to young, actively growing weeds. See the product label for application timing and directions.
GET TOUGH ON POA. Sertay delivers proven power to take on difficult Poa annua with visible results in 3-4 weeks. For improved effectiveness, apply Sertay in warm, moist conditions and apply to young, actively growing Poa (annual bluegrass) prior to tillering. Do not apply if rainfall or irrigation is expected within two hours after application.
TAKE WEED CONTROL TO THE LANDSCAPE LEVEL: Sertay power isnt limited to the lawn. Application around woody ornamentals, perennial groundcovers, and warm-season ornamental grasses keep landscaped areas weed-free. Sertay may be used in residential and business sites as well as on athletic fields and golf course fairways, roughs, and tees. See the product label for complete use site information.
IDEAL OVERSEEDING PARTNER: Use Sertay ahead of planting perennial ryegrass in the fall and during green-up in the spring for a clean start to each season. Follow the product label for overseeding application timing, rates, and directions.
HOLD BACK UNWANTED GRASS SPECIES IN WARM-SEASON TURF: Formulated specifically for southern lawns, Sertay suppresses invading cool-season species such as Poa annua (annual bluegrass), tall fescue, and perennial ryegrass. Sertay is labeled to safely use on the following warm-season grasses; bahiagrass, Bermudagrass, buffalograss, centipedegrass, kikuyugrass, St. Augustinegrass, seashore paspalum, and zoysiagrass. Refer to the product label for complete application directions.

Atticus

Atticus Torocity Herbicide (8oz) - (Compare to Tenacity) - Mesotrione Concentrate - Selective Weed Killer for Lawns and Turf Grasses - Pre and Post Emergent Control

Free Shipping

Main Highlights

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 doesnt occur within 10 days of application, water the area with 0.15 inches of water.
NOT AVAILABLE FOR SALE IN ALASKA, HAWAII, PUERTO RICO, OR VERMONT. Always read and follow label instructions.
