Sulfentrazone 4SC Select is selective herbicide that provides effective pre- and post-emergent control of broadleaf, grass, and sedge weeds. It contains 39.6% of Sulfentrazone as its active ingredient, the same as the popular Dismiss Turf Herbicide. This weed killer provides visible results in as little as 24 to 48 hours after application.
Sulfentrazone 4SC is a soil-applied flowable herbicide that can be used in both warm and cool season turfgrasses such as bahiagrass, buffalograss, carpetgrass, centipedegrass, kikuyugrass, zoysiagrass, bermudagrass, bentrgrass, fescue, ryegrass, bluegrass. It provides fast control of hard to kill weeds like black medic, pigweed, spurge, barnyardgrass, crabgrass, foxtail, goosegrass, chickweed, groundsel, carpetweed, clover, dandelion, dollarweed, ground ivy, henbit, plantain, kyllinga, nutsedge, but is gentle on established grass.
On grassy weeds, Sulfentrazone provides the best control when applied to grass that is small and actively growing. Broadleaf weeds are best controlled when applications are made shortly after the weed emerges.
*Please note: The 2.2 oz and 64 oz containers do not have a measuring device.

Apply Sulfentrazone 4SC Select as a broadcast treatment at rates indicated, in enough water to obtain good coverage and to make at least 10 gallons finished spray per acre. In order to assure appropriate amounts of moisture for activation, best results will be obtained if Sulfentrazone 4SC Select is applied in early spring, late summer or fall. Make application with a boom and nozzle sprayer or boomless application system. Make application at spray pressure of 25 psi or below, unless the manufacturer specifies otherwise. Achieve best possible spray delivery and coverage, with minimum amounts of fine spray droplets by utilizing properly chosen and adjusted nozzles, spray tips, and screens.
Best control is achieved with grassy weeds when applied with grasses are actively growing and small (pre tiller stage). Application rates lower than 12 fl. oz./ acre will control grasses for 60 days.
Optimum control of broadleaf weeds will occur if application is made shortly after weed emergence.
Applications to sprigged, overseeded or reseeded areas: turfgrasses can be sprigged, overseeded or reseeded after Sulfentrazone 4SC Select applications. Best results are obtained from waiting at least 1 month after Sulfentrazone 4SC Select application before sprigging, overseeding or reseeding. If slight plant response can be tolerated, overseeding of Bermudagrass with perennial ryegrass can be done between 2 to 4 weeks after Sulfentrazone 4SC Select application.
Observing proper fertilization, irrigation and soil cultivating practices, and using mechanical or power seeding equipment will give optimum overseeding or reseeding results.
Optimum weed control is obtained with thorough spray coverage.
Application Rates:
Apply 8 - 12 oz. per acre
Works well on Kyllinga
By Jp on 06/02/2018
I had a pretty serious invasion of Kyllinga in a section of my northern grass lawn (Ky bluegrass, fine & tall fescues, and perennial rye mix). In early May (typical daytime temps 80*F), I applied Sulfentrazone 4SC at a 6 oz./acre rate with a 2gal pump sprayer with a fan tip. At this rate, it killed broadleaf weeds in 48 hours or less. The Kyllinga took 3-4 weeks to die, as did a few spots of nutsedge, but control was very effective. It did no notable damage to the lawn grasses. Note that at this rate, the amount of product to use is very small. In 2 gallons of water I used 0.135 fl. oz. (3/4 tsp or 4mL) of product sprayed over +/- 1000 square feet. I have not yet used it with the intent of broadleaf weed control, but it seems that it would be very effective for this. I do plan to use it for late summer/early autumn pre-emergent weed control, but that will have to be a separate review.

I'm done with spot spraying for weeds
By Tom on 06/03/2020
Verified Purchase
Sulfentrazone 4SC Select is destroying my nutsedge, crabgrass, goosegrass, and some miscellaneous broadleaf weeds in my Bermuda lawn with no adverse impact to my Bermuda. I applied it yesterday using a towable sprayer and could not be more satisfied. Visible results were seen in hours, not days. I wish I could post a picture. There is nothing else I have used that kills goosegrass this dead without killing areas of my lawn. Many goosegrass plants turned from green to light brown overnight.

KILLS NUT GRASS IN THREE DAYS
By Matt on 09/17/2018
Excellent for Nutgrass
By Steve on 08/16/2019
One heaping teaspoon per gallon of water with Sticker eradicated my nutgrass in Tall Fescue. You have to be diligent about catching all small thin new eruptions or go back a Tim or two to catch all new growth. Excellent product!
