Solitare Herbicide, manufactured by FMC Professional Solutions, is an effective water-dispersible granule-formulated herbicide designed for selective weed control of various grassy and broadleaf weeds that commonly infest commercial and residential landscapes.
This easy-to-use herbicide contains two great active ingredients, sulfentrazone 18.75% and quinclorac 56.25%. If applied properly, these ingredients are effective in controlling over 60 different weeds while not damaging desired grasses.
Solitare Herbicide is a selective post-emergent herbicide that provides broad-spectrum control over various weeds on warm and cool-seasoned turf.
Tools Needed
Solitare Herbicide can be used in residential applications using a hand-held or backpack sprayer.
How to Use
- Step 1: Determine how much Solitare Herbicide to use by measuring the square footage of the treatment area. To do this, measure (in feet) the treatment areas' length and width, then multiply the two values (length X width = square footage). Solitare Herbicide can be mixed at a rate of 0.367 to 0.478 oz. of product per gallon of water for 1,000 sq. ft. of cool season grasses and at a rate of 0.367 to 0.735 oz. of product per gallon of water in warm-seasoned grasses. So, for example, if you measured a 2,500 sq. ft. area for treatment on warm season grass, you would need to mix 0.917 to 1.195 oz. of Solitare in 2.5 gallons of water.
- Step 2: Fill your selected sprayer halfway with water, then add the required amount of Solitare Herbicide to the tank based on your calculations. Replace the cap and agitate by shaking the sprayer. Add the remaining water required, then repeat agitation until the herbicide solution is thoroughly mixed.
- Step 3: Spray the target weed with the Solitare Herbicide mixture, using a fan spray setting to ensure even coverage. Wait 7 to 10 days to check progress and reapply if necessary.
Where to Use
Solitare Herbicide can be used in turf, including residential, commercial, and institutional lawns, athletic fields, commercial sod farms, golf course fairways and roughs, and other non-crop sites.
Do not use on turfgrasses other than those listed on this label. Do not treat pastures, rangeland, or other areas grazed or harvested for livestock forage or hay.
This product cannot be applied to golf courses, putting greens, collars, or tees.
When to Use
Apply Solitare Herbicide during peak weed-growing times of the year. It is best to target weeds when they are young and actively growing. The best weed control results will be obtained when no rainfall or irrigation occurs within 24 hours after application.
Do not apply to turfgrasses under stress.
Safety Information
Solitare Herbicide is safe to use around children and pets when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when mixing and applying this product.
Do not allow people or pets to enter the treatment area until the spray has dried.
Special Considerations
Do not use a surfactant with Solitare Herbicide. Surfactants may temporarily discolor some turf types, so they are not recommended.
