Crossbow Herbicide, manufactured by Helena Chemicals, is an easy to mix selective post-emergent herbicide. This herbicide provides unsurpassed control of annual and perennial broadleaf weeds, brush, trees, and woody plants in pastures, rangelands, non-crop areas, industrial sites.

As a water-soluble solution, Crossbow Herbicide allows the product to easily be mixed with various types of sprayer equipment for small or large volume applications.

Crossbow Herbicide is an effective liquid solution that works well in rainfall after 2 hours and will begin to work immediately once it makes contact with undesired leaves foliage. Results can be seen within a matter of days after application.

Tools Needed

To use Crossbow Herbicide, you will need a pump sprayer or backpack sprayer for smaller applications. For larger applications, use a spray rig.

How to Use

• Step 1: Determine how much Crossbow Herbicide you will need by calculating the square footage of the treatment area. To do this, you will need to measure and multiply length times width (length x width = square footage). For acreage, divide the square footage by 43,560 (square footage / 43,560 = Acreage). For small volume applications the rate is 1.33 to 5.33 fl. oz. of Crossbow Herbicide per gallon of water to cover 1,000 sq. ft. For large volume applications 1 to 4 gallons of Crossbow should be mixed per 100 gallons of water per acre.
• Step 2: Fill the spray tank with half of the amount of water required then add in the appropriate amount of Crossbow. Add in the appropriate amount of selected surfactant as suggested by the label and agitate the sprayer to make sure the solutions is mixed well.
• Step 3: Spray the application to targeted areas where weeds are growing, preferably on a fan spray setting for uniform coverage. If trying to control an invasive tree, you will need an oil-based carrier and will need to perform a cut-stump treatment. Apply enough spray to wet the lower 12 to 15 inches of the trunk, including the root collar.

Where to Use

Crossbow Herbicide can be used on rangeland, permanent grass pastures, and conservation reserve program (CRP) acres (including fence rows and non-irrigation ditch banks within these areas). 

When to Use

For best results, apply when plants are actively growing, which typically occurs early in the summer. Apply at least 10 days prior to leaf color change in late summer. Application in late summer or in periods of dry weather when plants are not actively growing may result in unsatisfactory control.

Safety Information

Crossbow is safe to use around children, pets, and livestock when applied according to the product label. Always wear the proper personal protective equipment (PPE) when mixing and when making applications. Do not enter treated areas for at least 12 hours.

Special Considerations

Low-volume basal and cut-stump applications require an oil-based carrier. Be sure pumps and hoses are resistant to oil-based carriers. Wands and spray tips also should be chemical-resistant. Adjustable tips give you more control when making individual plant treatments and there should be a cut-off at the tip to avoid wasting product (such as a strainer and check ball valve or low volume wand).

Though effective on its own, Crossbow Herbicide may be mixed with other products containing 2,4-D or Triclopyr as its active ingredient. This combined product must be labeled to be used on the same treatment site as Crossbow Herbicide and in accordance with the other product label instructions and treatment area.
