DIRECTIONS FOR USE:

ORNAMENTAL TURF AREAS

Lawns (Residential, Industrial and Institutional), Parks, Cemeteries, Athletic Fields and Golf Courses (Excluding Grasses Grown for Seed or Sod Farms).

Use 0.75 to 1.16 fl. oz. of product (0.022-0.034 lb ae) per 1,000 sq. ft. per application for control of annual broadleaf weeds. Use 1.16 fl. oz. of product (0.034 lb ae) per 1,000 sq. ft per application for control of biennial and perennial broadleaf weeds. Treat when weeds are young and actively growing. Perennial weeds should be near the bud stage, but not flowering at application. Use sufficient gallonage for thorough and uniform coverage.

SPOT TREATMENT IN ORNAMENTAL TURF AREAS (Parks, Cemeteries, Athletic Fields and Golf Courses, Turfgrass (excluding sod farms).

To control broadleaf weeds in small areas with a hand sprayer, use 1/4 pint of this product in 3 gallons of water and spray to thoroughly wet all foliage.

Do not exceed 4 pints of this product (2.0 lbs ae) per acre.

USE RESTRICTIONS FOR ORNAMENTAL TURF AREAS

(Golf courses, cemeteries, parks, sports fields, turfgrass, lawns and other grass areas)

Post-emergence:

  • Do not use on susceptible southern grasses such as St. Augustine.
  • Do not apply to newly seeded areas until grass is well established.
  • Bentgrass, clover, legumes and dichondra may be injured by this treatment.
  • Limited to 2 applications per year.
  • Maximum of 1.16 fl. oz. of product (0.034 lb ae) per 1,000 sq. ft. per application.
  • The maximum seasonal rate is 2.3 fl. oz. of product (0.068 lb ae) per 1,000 sq. ft., excluding spot treatments.

NON-SELECTIVE WEED CONTROL IN NON-CROPLAND AREAS

(Airfields, Roadsides, Vacant Lots, Drainage Ditchbanks, Fencerows, Industrial Sites, Rights-of-Way, Utility Power Lines, Railroads, and similar areas)

Use 1/2 gallon of product per acre. Use sufficient gallonage for thorough and uniform coverage. Apply when most annual broadleaf weeds are still young and growing vigorously. Apply when perennial and biennial weeds are actively growing and near the bud stage, but before flowering. Thoroughly wet weeds when applying this mixture. For best results on Tansy ragwort and Milk thistle, treat in rosette stage, before bolting. Treat Wild onion or garlic in early Spring and in Fall when they are young and growing actively.

The addition of a wetting agent (spray adjuvant) is suggested. Usually 4 pints per acre will give adequate control. Do not use on herbaceous ground covers or creeping grass such as Bent. Legumes will usually be damaged or killed. Deep-rooted perennials such as Bindweed, Whitetop, Perennial sowthistle, Blue lettuce, Nettle, Bur ragweed, Canada thistle and other noxious perennials somewhat resistant to 2,4-D may require repeat applications to kill. Do not use on freshly seeded turf until grass is well established. Delay reseeding for 30 days.

For chemical mowing applications on roadside and utility rights-of-way, using low volume spray equipment such as the “Lucas” 64 system use 1/2 gallon of this product in 1 to 5 gallons of water per acre.

Control of Southern Wild Rose: On roadsides and fencerows, use 1/2 gallon of this product plus the recommended rate of a high quality surfactant per 100 gallons of water and spray thoroughly as soon as foliage is well developed. Two or more treatments may be required.

USE RESTRICTIONS FOR NON-SELECTIVE WEED CONTROL IN NON- CROPLAND AREAS (airfields, roadsides, vacant lots, drainage ditchbanks, fencerows, industrial sites, rights-of-way, utility power lines, railroads, and similar areas)

Post-emergence (annual and perennial weeds):

  • Limited to 2 applications per year.
  • Maximum of 4.21 pints of product (2.0 lbs ae) per acre per application.

BRUSH CONTROL

(Including Rights-of-Way, Fence Rows, Roadsides and along Ditchbanks)

WOODY PLANT CONTROL: To control woody plants susceptible to 2,4-D such as Alder, Buckbrush, Elderberry, Sumac, Cherokee rose, Japanese honeysuckle, Virginia creeper, Wild grape and Willow on non-crop areas such as rights-of-way, fence rows, roadsides and along ditchbanks. Use 2 to 3 quarts of product per acre in 30 to 100 gallons of water. Lower volume of water can be used unless applying through such equipment as a DirectaSpra, Wobbler, or Spirometer. Spray brush 5 to 8 feet tall after Spring foliage is well developed. Wet all parts of the plants thoroughly, including stem and foliage, to the point of runoff. Higher volumes of up to 300 to 500 gallons of spray per acre may be necessary where the brush is very dense and over 6 to 8 feet high. Spraying can be effective at anytime up to 3 weeks before frost as long as soil moisture is sufficient for active growth of the brush.

Control will be less effective in mid-Summer during hot, dry weather when soil moisture is deficient and plants are not actively growing. A wetting agent may be added to the spray if needed for increased effectiveness. Hard-to-control species may require re-treatment next season. In general, it is better to cut tall woody plants and spray sucker growth when 2 to 4 feet tall.

SAND SHINNERY OAK AND SAND SAGEBRUSH: On the oak, use 2-1/4 pints of this product in 5 gallons of water per acre. Apply by aircraft between May 15 and June 15. On the sagebrush, use 2-1/4 pints in 3 gallons of water per acre and apply by aircraft when foliage is fully expanded and the brush is actively growing.

BIG SAGEBRUSH AND RABBITBRUSH: Use 2-1/4 to 6-3/4 pints of product per acre in 2 to 3 gallons of water. For rabbitbrush, the 6-3/4 pints rate is usually required. Brush should be leafed out and growing actively when treated. Retreatment may be needed.

CHAMISE, MANZANITA, BUCKBRUSH, COASTAL SAGE, COYOTEBRUSH AND CERTAIN OTHER CHAPARRAL SPECIES: Use 2-1/4 to 6-3/4 pints per acre in 5 to 10 gallons of water. Make applications by aircraft or ground equipment to obtain uniform spray coverage. For effective control, the brush must be fully leafed out and growing actively when sprayed. Retreatment may be needed. Consult State or local brush control specialists for most effective rate, volume and timing of spray application.

CATTAILS, TULE (BULRUSH), AND OTHER RUSHES: Mix 4 pints of this product and 100 gallons of water (1-1/2 to 2 quarts of this product in 400 to 800 gallons of spray per acre). Addition of a wetting agent may be advisable. Apply in the spring during flower head emergence. Spray to wet all foliage. Re-spray if needed when regrowth is 3 to 5 feet tall.

    Confused

    By Robin on 07/04/2020

    I ordered 2,4-D Amine NO.4 but I received 2,4-D Amine. Are these two products the same. Read booklet on container and they seem to be. Going to use close to pond so I hope I don’t get a fish kill.
