Outrider Herbicide
Outrider Herbicide is an easy-to-use systemic pre- and post-emergent herbicide that controls a wide range of weeds in pasture grasses, rangelands, and non-crop areas.
10/07/25
Outrider Herbicide, manufactured by Valent, is an effective water-dispersible granule (WDG) used for selective pre-emergent and post-emergent control of grassy and broadleaf weeds in non-crop lands and sites that might require bare ground vegetation management, such as fence rows.
As a systemic herbicide, it works by absorbing into the plants through the plants' roots and foliage. Once 2 hours have passed after application, this product becomes rainfast to prevent needless retreatments, making it economical.
Outrider Herbicide offers broad-spectrum control of annual and perennial broadleaf and grassy weeds like nutsedge without harming turfgrasses.
Tools Needed
For general weed and grass control, it is recommended to use either a pressurized pump or backpack sprayer, handheld spray guns, or similar spraying equipment. For large applications, use a professional spray rig.
How to Use
- Step 1: Determine how much Outrider Herbicide to use by measuring the square footage of the treatment area. To do this, measure the length and width of the treatment area in feet, then multiply them together (length X width = square footage). For acreage, divide the square footage by one acre (square footage / 43,560 sq. ft. = acre). The typical application rate for Outrider is 0.75 to 2.0 oz. per acre in at least 10 to 50 gallons of water. For small applications with a handheld sprayer, apply 1 oz. of product and a quart of nonionic surfactant at a rate of 2 gallons of spray solution per 1,000 sq. ft. Your application rate will vary on targeted plant, dilutions ratio, and application method. The combined total of all types of applications of this product must not exceed 2.66 oz. of product per acre per year.
- Step 2: Fill your spray tank about three-fourths full with water. Add the required amount of product per the label directions. Then, fill the rest of the tank with water to create proper agitation and a thorough mix. A surfactant must be mixed into the solution at a 25% by-volume dilution for post-emergent applications unless it is being used with Roundup Pro herbicides.
- Step 3: Spray the targeted grasses or weeds, ensuring you get even coverage. Use a coarse spray only, and do not spray to the point of runoff.
Where to Use
Outrider Herbicide can be used in non-crop areas, on dormant or established bermudagrass or bahiagrass, roadsides, pasture and rangeland sites in states west of the Mississippi River, non-crop tree sites, native grasses, and conservation reserve program (CRP) sites, winter wheat, and spring wheat.
Do not use on or around golf courses, residential turf sites, athletic fields, commercial turf sites, sod and turfgrass seed farms, bodies of water, and known habitats for threatened or endangered species.
When to Use
Apply as a pre-emergent preventative to stop labeled grasses and weeds from sprouting. This can also be used as a post-emergent - after weeds have sprouted - to care for and eliminate troublesome grasses and weeds.
In Texas, this product applied before September 30 will not delay the greening up of Bermudagrass the following spring; however, some temporary discoloration of desirable spring germinating wildflowers may occur.
Do not seed any crop, except wheat, any sooner than 3 months after the last application of this product. There are no crop rotation restrictions for wheat.
Safety Information
Outrider 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.
Keep people and pets off-treated areas until the spray solution has dried.
Wheat forage may be grazed immediately after application of this product. Do not harvest wheat for hay within 30 days of Outrider Herbicide application. Do not harvest wheat for grain within 55 days of application of this product.
Special Considerations
Unless being used alongside Roundup Pro, Outrider Herbicide requires that a non-ionic surfactant to be mixed into solution for post-emergent control. Tank mixtures that have amine formulated herbicides will decrease Outrider's effectiveness.
