Quick Facts
- Controls your toughest, yield-robbing broadleaf weeds.
- Apply pre-plant or pre-emergence to control weeds early and gain extra yield.
- Group 14 mode of action for managing weed resistance.
- Soil applied.
- If there is a lack of adequate or normal soil moisture due to drought conditions, especially in June, July and August, following an application of Authority® 480 herbicide, the minimum rotational crop interval described below must be extended for one additional year and a representative bioassay of the field must be conducted with the potential rotational crop and adequate soil moisture to determine the crop sensitivity to Authority® 480 herbicide.

Product Overview
Authority® 480 herbicide is a powerful, flexible pre-emergent Group 14 herbicide that provides extended activity on challenging weeds like kochia, redroot pigweed, lamb’s-quarters, wild buckwheat and cleavers. Authority® 480 herbicide can be tank-mixed with glyphosate.
As a Group 14, Authority® 480 herbicide is active on the following resistant weeds: redroot pigweed (Groups 2 and 5), lamb’s-quarters (Group 2), cleavers (Groups 2 and 4), kochia (Groups 2, 4, 5 and 9) and wild buckwheat (Group 2).
One small case of Authority® 480 herbicide treats 128 acres to 172 acres, with a convenient liquid formulation, compared to 80 acres for one large tote of competitive granular herbicide.

Tech Specs
Chemical Group: Group 14 for herbicide resistance management.
Registered and Supported Tank Mixes:
- Aim® E + glyphosate
- Aim® EC + MCPA amine + glyphosate (flax only)
- Glyphosate
- Enlist herbicide
- Express® FX herbicide
- Express® SG herbicide

Timing: Authority® 480 herbicide alone, or in recommended tank-mixes, may be applied to the soil surface as a broadcast spray prior to or after planting of the crop (no later than 3 days after seeding), but prior to weed or crop emergence. Authority® 480 herbicide requires 1/2” of moisture, at once, for activation, whether the total amount of moisture is received by rainfall or irrigation. See label for specific directions in dormant, established alfalfa grown for seed production.
Application Information:
- Apply pre-plant or post-seed (up to 3 days after seeding)
- Early application (pre-plant) increases activation potential via spring showers. Post-seed application should be considered in higher disturbance situations.
- Clean out tank after using Authority® 480 herbicide. When spraying Authority® 480 herbicide for multiple days, at the end of each day, rinse tank with water and leave 1/3 full of water overnight. Use 50 mesh screens.
- Do not apply Authority® 480 herbicide to fields treated with products containing sulfentrazone in the previous year.
- Do not apply Authority® 480 herbicide (or any other product containing sulfentrazone) to spring wheat if an application of Focus® herbicide (or any other product containing pyroxasulfone) was applied in the previous fall.
- Do not apply to soils classified as coarse-textured soils.
- Do not apply in any type of soil with organic matter lower than 1.5% or greater than 6%.
- Do not use on soils with a pH of 7.8 or greater."
Rates & Packaging: 4x3.79 L jugs per case. Each 3.79 L jug treats 32 or 43 acres
Water Volume: 10 US gal/ac (100 L/ha) provides best uniform soil coverage with medium to coarse droplet sizes
