Product Overview

GrazonNext HL Herbicide is a broadleaf weed control product that will kill more than 100 different types of weeds, including the more difficult to kill perennials, like nightshades and bull nettles. Quickly killing the existing weeds and keeping them from coming back, the product also works great with liquid fertilizers and can be safely used around grazing areas of livestock, Conservation Reserve Program land and wildlife management areas. GrazonNext HL Herbicide also comes with no restriction for any kind of livestock, including beef cattle, goats, horses, nursing dairy animals, and sheep and won't harm desirable grasses like bahiagrass, bermudagrass, fescue, orchard and other mixed native grasses. Just follow the directions on the bottom description on what rate of dilution is required to kill your problem weed and your property will be weed free in no time. The product works great with brush control herbicides, like Remedy Ultra, which can be mixed and applied at the same time, massively reducing the time it takes to undertake an integrated vegetation management program.

Only apply this product if the wind direction favors on-target deposition and there are not sensitive areas (including, but not limited to, residential areas, bodies of water, known habitat for nontarget species, nontarget crops) within 250 feet downwind.

This product replaces Forefront HL Herbicide.

    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.

    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.

What is the mix rate and application instructions to apply GrazonNext HL Herbicide to 5 acres using a 4 gallon boomsprayer?

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.
