How To Use Halo 75 WDG Select Herbicide

When used as directed, Halo 75 WDG Select is safe for use around people and animals of all ages. When handling, mixing or spraying this product, it is imperative that you always use the proper PPE.

If you notice any nutsedge plants in your lawn, treat them when they have three to five leaves.

This product should be sprayed when the temperature is above 50 degrees and below 92 degrees Fahrenheit and there is no chance of precipitation for at least three days following application.

Drift can be prevented by using nozzles and pressures (40 PSI) that produce coarse particles rather than fine ones.

You should stay away from treated foliage for a week so the substance can penetrate the foliage and kill any weed seeds that may have germinated.


What Is the Halo 75 WDG Select?

The water-dispersible granule herbicide Halo 75 WDG Select, made by Prime Source LLC, is highly effective against nutsedge and broadleaf weeds like ragweed in their germination and early growth stages.

The same active component that is in Sedgehammer is included in Halo 75WDG.

The growth of the weeds is stifled, and the crop is then able to take over. After being exposed to UV rays, weed growth will wilt and die.

By blocking the production of acetolactate, an enzyme crucial to weed growth, this product can be used either after weeds have emerged or before they have germinated to provide rapid weed control.

Discoloration and eventual death of the weed’s leaves and growing point follow the disruption of the weed’s development system.

How To Use Halo 75 WDG Select

  • Determine the square footage by multiplying the feet of length by the feet of breadth. You may calculate the acreage by dividing the square footage by the number of acres. Acreage equals 43,560 square feet (square footage / 43,560).
    Use 0.03 (0.9 grams) of Halo 75 WDG for broad spot treatments. Choose between 1-2 gallons of water for every 1,000 square feet.
    A non-ionic surfactant such as Alligare 90 can be added at the rate of 2 teaspoons (1/3 oz.) per gallon of water. Spread treatments require 15-20 gallons of water per acre, and the recommended dosage ranges from 0.5 to 5.33 ounces of product.
    It is not recommended to use more than 5 1/3 ounces of this product (0.25 lb. active ingredient) per acre each use season on turf. For instructions on how much to use, read the product’s label.
  • Fill your pump or backpack sprayer halfway with water, then add the specified amount of Halo 75 WDG, and mix thoroughly. Choose your surfactant (if you’re using one) and add the remaining half of the water.
    Put the top back on, and give it a good shake to combine everything. Put the product and surfactant in the hose-end sprayer container and then screw it onto the end of your hose. To avoid adding water, just spray the hose.
  • Cover both the upper and lower surfaces of the desired foliage by spraying from directly above (no more than 4 feet above the ground), but not so much that the liquid runs off. Spraying above desirable foliage could cause damage to the plants.
    Wait two to three days before watering after spraying emergent weeds. Then, irrigate with a one-inch depth once the given time has gone. Once 6-10 weeks have gone since the initial application, a second one can be used.

Because Halo 75 WDG Select is toxic to non-target vascular plants, it may not be effective if the weeds or turf are already suffering from conditions like drought, stress, disease, or insect damage.
