GrazonNext HL Herbicide is a selective post-emergent herbicide designed to control tough broadleaf weeds and woody brush in pastures, rangelands, and permanent grass areas. It is commonly used to treat thistle species, blackberry, and other hard-to-control weeds while preserving desirable grasses when applied according to the product label.
GrazonNext HL Herbicide should be applied when weeds are actively growing for the best results. Avoid applications when rain is expected within 2 hours after treatment. After rainfall, the product can generally be applied once foliage is dry and weeds are no longer dripping wet.
GrazonNext HL Herbicide is designed for broadleaf weed control in pastures, rangeland, and other non-crop grass areas. This selective herbicide provides fast burndown and season-long control of more than 100 tough weeds, including Canada thistle, horsenettle, Texas bull nettle, cocklebur, curly dock, ragweed, and other hard-to-kill perennial and annual broadleaf weeds. GrazonNext HL also helps suppress encroaching brush while remaining safe for desirable pasture grasses such as bermudagrass, bahiagrass, fescue, orchardgrass, and mixed native grasses when used as directed.
Do not apply GrazonNext HL Herbicide to residential lawns, ornamental turf, golf courses, athletic fields, commercial sod farms, driveways, walkways, tennis courts, or other high-maintenance turfgrass areas.

GrazonNext HL Herbicide offers both pre-emergent and post-emergent activity on many broadleaf weeds and works well as a tank mix partner with liquid fertilizers and brush control herbicides such as PastureGard HL and Remedy Ultra.
This herbicide has no grazing restrictions for livestock, including beef cattle, dairy animals, sheep, goats, and horses, when used according to the product label. GrazonNext HL is also not classified as a federally Restricted Use Pesticide. Do not apply more than 2.1 pints (34 fl oz) per acre per season. Treated areas should not be rotated to cropland for at least one year following application
The amount of GrazonNext HL Herbicide per gallon depends on the size of the treatment area and the target weeds. For spot treatments, most applications use the labeled rate per 1,000 square feet mixed into 1 gallon of water.
For broadcast applications, the water volume can vary based on spray equipment and coverage needs. In most cases, applicators use enough water to evenly cover the treatment area, typically around 1 to 3 gallons of water per 1,000 sq ft.
To properly mix GrazonNext HL Herbicide:
GrazonNext HL Herbicide does not need to be premixed separately before adding it to the sprayer tank.
The amount of product needed depends on the weed being treated and how much area your sprayer covers.
For example, if treating blackberry or tougher thistle species at the higher labeled rate of 1.5 to 2.1 pints per acre, calibrate your sprayer first to determine how many gallons of water are needed to cover 1 acre (43,560 sq ft).
A common broadcast application uses approximately 3 gallons of water per 1,000 sq ft, which equals about 130 gallons of spray solution per acre. If using a 40-gallon boom sprayer, you may need about 3 tank refills per acre, depending on your calibration and walking or driving speed.
You may begin seeing visible results from GrazonNext HL Herbicide within a few days after application. Complete control can take several weeks, depending on the weed species, the maturity of the weeds, and the overall growing conditions.
Actively growing younger weeds typically respond faster than mature or stressed plants.
The recommended GrazonNext HL Herbicide mix rate depends on the specific thistle species being treated.
For yellow starthistle, bull thistle, musk thistle, and plumeless thistle, apply:
For Canada thistle, scotch thistle, sowthistle, and prickly sowthistle, apply:
When spot treating with a hand pump or backpack sprayer, use the recommended rate per 1,000 sq ft in 1 gallon of water.
Be careful if using for hay or manure from treated fields
By Gail on 08/05/2019
Be very careful using Aminopyralid. if the cows or horse eat the grass treated or hay treated it passes thru intact. Lost a large part of my tomatoes and potatoes to composted cow manure that contained was contaminated by this. Minute concentrations of picloram, clopyralid and aminopyralid, as low as 1 ppb (parts per billion), can be lethal to sensitive garden plants such as peas, beans, lettuce, spinach, tomatoes and potatoes. Takes years and years to get cleared from soil. Only good plant to put in affected garden soil is corn.

THE PASTURE WEED KILLER
By Bob on 08/24/2017
Test results used on Bahia grass hay.
By Edward on 06/03/2018
I am testing this product on three types of weeds that are affecting the quality of my hay fields. Our LSU AgCenter agent listed GrazonNext HL as one of the Herbicides used in their test to control "Horsenettle, Johnson Grass, and Pigweed". So far my test are showing control of all three. I plan to treat all fields next year. Thanks for a great product.

Texas Bull Nettle Killer
By Bryon on 07/29/2017
GrazonNext HL Herbicide is best applied when rain is not expected within 24 hours after application. As long as the weeds being controlled are not drenched/dripping water prior to application it can be applied after rain within a few hours.

There are no grazing restrictions using GrazonNext HL Herbicide. We would suggest they not be in the area during the application and while the surfaces are wet, once the treated surfaces are completely dry then they can return.

I've read the label on my grazon HL and I simply don't understand the mixing ratio or technique. Can I pour the grazon into the tank or do I premix it in 3 gl of water. Please give me direction on how to apply
Without knowing the specific weeds you are targeting, we are unable to give an exact mix rate. GrazonNext HL Herbicide is applied at 19-34 fl oz per acre (43,560 sq ft). The amount of water will depend on how much water it takes to cover 1,000 sq ft thoroughly. Typically 1-2 gallons of water every 1,000 sq ft is sufficent, the label is recommending to use 3 gallons of water every 1000 sq ft to ensure the active ingredient in GrazonNext gets into the soil. Please see the break down below.
To treat each of the 5 acres, you would need 130 gallons of water for each acre. ** 1 acre = 130 gallons of water (3 gal of water x 43,560 sq ft (sq ft in acre)
You would need to refill your sprayer approx 3 times to thoroughly treat 1 acre.
Depending on what weeds you are targeting, you will divide the 19 fl oz, 24 fl oz or 34 fl oz mix rate per acre and divide by 3 (the # of times you will fill the 40 gal sprayer) .
Low Rate 19 fl oz / 3 tank fills = 6.3 fl oz per tank
Mid Rate 24 fl oz / 3 tank fills = 8 fl oz per tank
High Rate 34 fl oz / 3 tank fills + 11.3 fl oz per tank
You can mix the GrazonNext directly into the tank. To prepare the spray, add about half the required amount of water in the spray tank. Then, with agitation, add the specified amount of GrazonNext HL and other registered tank mix herbicides. Finally, with continued agitation, add the rest of the water and additives such as surfactants or drift control and deposition aids.
GrazonNext HL Herbicide is a post-emergent herbicide so it can be used any time the weeds are in an actively growing state. If the weeds are apparent now, then you can use the product now to try and eliminate them. The rate range for GrazonNext HL Herbicide is 1.2 to 1.5 pints (19 to 24 fluid oz) product per acre. Please provide details on your application for specific information.
