Expel Turf Herbicide is a highly effective solution against a wide range of tough undesired weeds, grasses, and sedges. Contains sulfentrazone as its active ingredient which is known for powerfully inhibiting the photosynthesis of plants, disrupting their growth. It controls even the most difficult weeds such as green kyllinga and yellow nutsedge. Expel Turf Herbicide is specially formulated to provide fast-acting control, offering visible results within 24 hours. It is a soil-applied selective post-emergent herbicide that is proven to target sedges and other weeds from above and below the surface. Ideal for use in both cool and warm-season grasses, residential and commercial areas, golf courses, athletic fields, and commercial sod farms. An excellent herbicide that kills and eliminates purple nutsedge, dandelion, clover, chickweed, beggarweed, ground ivy, carpetweed, buttercup, dock, black medic, and many more. Available in a 32-ounce bottle.
This pesticide is toxic to marine/estuarine invertebrates. Do not apply directly to water, to areas where surface water is present or to intertidal areas below the mean high water mark. Drift and runoff may be hazardous to terrestrial and aquatic plants in neighboring areas. Do not contaminate water when disposing of equipment washwaters or rinsate.
DIRECTIONS FOR USE
It is a violation of Federal law to use this product in a manner inconsistent with its labeling.
Do not apply this product in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be in the area during application. Applicators must not exceed labeled rates of this product. Refer to specific crop directions for use for maximum use rates. Calculate the 12-month period for the purpose of maximum use rates from when EXPEL is first applied.
For any requirements specific to your State or Tribe, consult the Agency responsible for pesticide regulation.
Apply EXPEL 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.
When EXPEL is tank mixed or applied alone, use water, as the carrier.
In order to assure appropriate amounts of moisture for activation of product, best results will be obtained if EXPEL 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.
Applications by helicopter can only be made to railroad rights of way.
Do not allow spray to drift onto adjacent plants as injury to other plants may occur.
When EXPEL has been activated, it will provide control of listed weed species. The level of control will depend on the size and type of weed species when EXPEL is activated. The control of listed germinating weed species will be reduced when rain or irrigation follows a period of dry weather.
Where there are prolonged periods when rainfall/irrigation is not available, alternative weed control methods should be considered.
Once a treatment with EXPEL has been made, seedlings and germinating seeds absorb sulfentrazone from the soil solution. The amount of available active ingredient contained in the soil solution, is determined by the following factors:
soil organic matter
CALIFORNIA ONLY SPECIFIC RESTRICTIONS ON APPLICATIONS OF EXPEL
Runoff Ground Water Protection Areas. Do not use in areas identified by the California Department of Pesticide Regulation as runoff ground water protection areas* unless one of the following management practices can be met:
a) Incorporation of the pesticide. Within 48 hours after the day this product is applied, the pesticide shall be incorporated on at least 90 percent of the area treated; using a disc, harrow, rotary tiller, or other mechanical method, or by sprinkler or low flow irrigation, including chemigation where allowed by the label, using a minimum of ¼ inch of irrigation water and a maximum of one inch as described under Application Instructions, at application rates that do not cause surface water runoff from the treated property or to wells on the treated property; or
b) Retention of runoff on field. For six months following the application, the field shall be designed, by berms, levees, or nondraining circulation systems, to retain all irrigation runoff and all precipitation on, and drainage through, the field. The retention area on the field shall not have a percolation rate of more than 0.2 inches per hour (5 inches per 24 hours); or
c) Retention of runoff in a holding area off the field. For six months following application, all runoff shall be channeled to a holding area off the application site, under the control of the property owner, that is designed to retain all irrigation runoff and all precipitation on, and drainage through, the treated field and all other areas draining onto that holding area. The holding area shall not have a percolation rate of more than 0.2 inches per hour (5 inches per 24 hours); or
d) Runoff onto a fallow field. For six months following application, runoff shall be managed so that it runs off onto an adjacent unenclosed fallow field at least 300 feet long that is not irrigated for six months after application with the exception of the addition of adequate moisture that is required for herbicidal activation following application as described under Application Instructions, with full consideration of any plant back restrictions.
Am a commercial applicator for context. I bought this to treat primarily Poa Annua w/ some nutsedge and winter broadleaf pressure in mostly Zoysia. Results in cool weather were so-so. I'm still not sure where I stand w/ Sulfentrazone. Too hot and it damages, too cool and it doesn't make financial sense. Reminds me of MSM in many ways
