The dilution rates for GrazonNext HL Herbicide? will vary depending on the weeds you are targeting and the application site. Please refer to the product label for the appropriate rate for your needs.
GrazonNext HL Herbicide is not labeled to treat for milkweed but for woolly croton the rate range per the label is 1.2 to 1.5 pints (19 to 24 oz) per acre. Best weed control results are obtained when spray volume is sufficient to provide uniform coverage of treated plants. The amount of water is not set and is however much water it takes for you to cover the acre. It could be at least 20 gallons of water up to 100 gallons.
For milkweed it appears that glyphosate is the best product for it but it could also kill anything desirable that it is sprayed to so care should be taken if used.
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.
Yes, GrazonNext HL Herbicide is applied at 19-34 fl oz per acre (43,560 sq ft) for horse nettle/bull nettle. The amount of water will depend on how much will cover a 1,000 sq ft uniformly, usually 1-2 gallons of water per 1,000 sq ft. Be sure to review the full product label before use since there are many restrictions regarding the use of this herbicide.
The dilution rates for GrazonNext HL Herbicide will vary depending on the weeds you are targeting and the application site. Please refer to the product label for the appropriate rate for your needs.
GrazonNext HL Herbicide is not labeled to treat leafy spurge or whitetop. The labeled rate for knapweed and gumweed is 24-34 ounces of GrazonNext HL Herbicide per acre.
GrazonNext should not be used around desirable crops. Per the GrazonNext HL Herbicide label, you should avoid application under conditions that may allow spray drift because very small quantities of spray, which may not be visible, may seriously injure crops. Susceptible crops include, but are not limited to, cotton, okra, flowers, fruit trees, grapes (in growing stage), fruit trees (foliage), soybeans (vegetative stage), ornamentals, sunflowers, tomatoes, beans, and other vegetables, or tobacco. GrazonNext HL provides preemergence control of germinating seeds or emerging seedlings of susceptible weeds and re-growth of certain perennial weeds following application. When to apply depends on your application type, either as a pre-emergent (before seeds germinate) or post emergent application (anytime weeds are actively growing).
Per the product label for GrazonNext HL Herbicide
Preemergence: Grasses may be reseeded in the fall following an application of GrazonNext HL applied in the spring or early summer.
Postemergence: During the season of establishment, GrazonNext HL should be applied only after perennial grasses are well established (have developed a good secondary root system and show good vigor). Most perennial grasses are tolerant to GrazonNext HL at this stage of development. GrazonNext HL may suppress certain established grasses, such as smooth bromegrass (Bromus inermis), especially when plants are stressed by adverse environmental conditions. Plants should recover from this transient suppression with the onset of environmental conditions favorable to grass growth and upon release from weed competition
GrazonNext HL Herbicide is not labeled for prickly pear. Prickly pear is very hard to control and we could recommend E-2 Herbicide as a way to treat it.
Per the GrazonNext Product Label: Spot Application: Spot treatments may be applied at rates equivalent to broadcast-applied rate of up to a maximum of 4.2 pints (68 fl oz) on 50% of the treated field. Spray volume should be sufficient to thoroughly and uniformly wet weed foliage. Repeat treatments may be made, but the total amount of GrazonNext HL applied must not exceed 2.1 pints (34 fl oz) per acre per year (see comments in the Use Precautions and Restrictions section above on Maximum Application Rate).
