GrazonNext HL Herbicide, produced by DOW/CORTEVA, is a reliable broadleaf herbicide that controls over 100 weed species for 2 to 4 weeks after application.
With two active ingredients, it effectively targets a wide range of annual, biennial, and perennial broadleaf weeds, including nightshades, Canada thistle, horsenettle, and clover. One application provides lasting control, reducing the need for repeated treatments.
This herbicide is practical for ranchers because of its season-long effectiveness and forage safety. It offers dependable weed management without harming forage quality or livestock health.
Tools Needed
Use with a backpack sprayer or spray rig.
How to Use
- Step 1: Calculate the treatment area by measuring length and width in feet and multiplying to find square footage. Convert to acres by dividing square footage by 43,560. Typically, apply 0.44 fl. oz. of GrazonNext HL per gallon of water per 1,000 sq. ft. Follow the product label for exact rates.
- Step 2: Fill the sprayer tank halfway with water, add the measured amount of herbicide, then fill with the remaining water. Close the tank and mix well.
- Step 3: Spray evenly across the area. Limit applications to two per year. If a second treatment is needed, wait 30 days after the first.
Where to Use
Suitable for rangelands, permanent grass pastures (including hay grasses*), Conservation Reserve Program (CRP) lands, and wildlife management areas like dry flood plains, deltas, marshes, prairie potholes, or vernal pools in those sites.
When to Use
Apply when weeds are less than 2 inches tall and no rain is expected for at least 24 hours after treatment.
Safety Information
When used as directed, GrazonNext HL is safe around children and pets. Always wear appropriate personal protective equipment (PPE) when handling and applying. Keep people and pets out of treated areas for at least 2 days.
Special Considerations
Avoid runoff or soil movement containing GrazonNext HL onto crop land. Exposure may damage or kill sensitive crops like grapes, soybeans, tobacco, and certain ornamentals.
