Chaparral Herbicide, manufactured by DOW/CORTEVA, is a broad-spectrum herbicide that is made for controlling broadleaf weeds and woody species in pastures and rangelands.

The active ingredients in Chaparral is Aminopyralid and metsulfuron which means it has a more than one mode of action, helping it to control many different weeds that other herbicides fail to control. Applying Chaparral is also helpful for cattle, keeping them grazing longer by providing more foraging land and promoting the growth of desired vegetation.

Tools Needed:

To use Chaparral, you can apply this product with a hand pump sprayer, a backpack sprayer, or a hose end sprayer for small to medium applications. For large volume application, Chaparral can be applied with a pesticide spray rig, a boom sprayer or even aerial application.

How to Use:

• Step 1: Determine how much Chaparral 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, take the square footage and divide it by one acre (square footage / 43,560 sq. ft. = acre). This is to help determine how much product should be mixed and used, and at what dilution rate. Spot treatments of Chaparral may be applied at a rate of up to 2.5 oz per acre for weeds and 3.3 oz. for brush per 100 gallons of water.
• Step 2: Fill your sprayer halfway with water, then measure and add the required amount of product. Thoroughly agitate the sprayer to dissolve the granules, then add the rest of the water. Agitate your sprayer again, and you're ready to apply.
• Step 3:  Apply the product evenly over the desired area, making sure not to overlap and reduce drift as much as possible.
• Step 4: Reapply as recommended by the label, and be sure not to over-apply as this could damage the plants. The max rate per year is no more than 3.3 oz./acre of Chaparral per year

Where to Use:

Chaparral is intended for use on rangeland, permanent grass pastures (including grasses grown for hay*), Conservation Reserve Program (CRP) acres, natural areas (such as wildlife management areas, wildlife openings, wildlife habitats, recreation areas, campgrounds, trailheads and trails), and grazed areas in and around these sites.

Do not apply this product on lawns, turf, ornamental plantings, urban walkways, driveways, tennis courts, golf courses, athletic fields, commercial sod operations, or other high-maintenance, fine turfgrass areas, or similar areas.

When to Use:

Chaparral Herbicide is best applied on actively growing weeds from spring to early summer.

Do not apply Chaparral Herbicide to an entire farm or ranch in one year.

Do not rotate to any crop from rangeland, permanent pasture, or CRP acres within one year following treatment with this product. Cereals and corn can be planted one year after treatment. Most broadleaf crops are more sensitive and can require at least 2 years depending on the crop and environmental conditions.

Safety Information:

Chaparral 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.

Pets and children should not be present during treatment and should remain out of the treated areas until they have completely dried.

Special Considerations:

Read the label carefully before applying Chaparral on your property. When a rate range is given, use the higher rate to control weeds at advanced growth stages, or under less than favorable growing conditions, or for longer residual control. For best results in the product having a good uptake and systemic movement avoid mowing, haying, shredding, burning or soil disturbance in treated areas for at least 14 days following application.
