How To Use Q4 Plus Herbicide

Extreme heat might cause harm or discoloration, therefore using Q4 Plus Herbicide in the late evening or afternoon is not recommended.

Do not use a sweeping or swinging action when spraying with a flat fan nozzle tip. Do not move it; rather, keep it at the right height in a fixed position. Uneven coverage is achieved when spraying in a side-to-side motion.

When used as directed, Q4 Plus Herbicide is harmless to humans, animals, and the environment. When handling, mixing or applying this product, it is imperative that you always use the necessary PPE.


What Is the Q4 Plus Herbicide?

Its concentrate’s four effective ingredients—Quincolarac (8.43%), Sulfentrazone (0.69%), 2,4-D (11.81%), and Dicamba (1.49%)—pack a hefty punch against weeds in residential and commercial grass. This unique synergy between systemic and contact-active chemicals completely controls weeds without harming desirable foliage.

Only use on fine fescue if you have a mixture of cool-season grasses and blends. Listed tolerant turf types may experience short-term turf injury. Conditions favorable to turfgrass promote the highest level of tolerance.

With visible results in only 7 days and a reseeding interval of just 4 weeks, Q4 Plus Herbicide makes emerging weed control quick and easy. The herbicide is cost-effective since it continues to kill weeds even after it rains, which can happen as soon as 6 hours after application.

  • Square footage is calculated by multiplying the linear feet of length by the linear feet of breadth. Simply divide the total square feet by 43,560 to get the acres.
    For applying a spot treatment of Q4 Plus Herbicide to cool-season grass, the rate per 1,000 square feet of turf is 2.6 to 3.0 fluid ounces of herbicide per gallon of water.
    The recommended ratio for broadcast applications on cool-season turf is 7 to 8 pints of product to 20 gallons of water per acre. Use 1.84–2.57 fluid ounces of product to 1 gallon of water per 1,000 square feet of turf for spot treatments on warm-season grass.
    Use 5–7 pints of product per 20 gallons of water per acre for broadcast applications on warm-season turf. A minimum of 30 days must pass between broadcast applications on ornamental grass and non-crop areas, and the annual maximum is 2.
  • Start by filling your chosen sprayer halfway with water, then add the specified amount of Q4 Plus Herbicide, and finally fill the spray tank to its final capacity with the remaining water. Put the top back on and give the solution a good shake to get it all mixed up.
  • Apply to spray on all sides of weed leaves until they are damp, but not dripping wet. Don’t water-treated areas for at least 24 hours following treatment.
    For warm-season grasses, such as Bermudagrass and Zoysiagrass, you can ignore this guideline and water a half an inch before and after application instead (as directed on the product label). If it doesn’t rain between 2-7 days of application, you should water with at least half an inch.
    If reapplication is necessary, at least 30 days should have passed since the previous treatment was performed on ornamental turf and non-crop areas, and at least 21 days on sod farms.
  • Using Q4 Plus Turf effectively requires calibration and application. It is important that the spray is equal and covers everything.
    Injury to turfgrass may come from excessive applications.
  • In order to treat 1,000 square feet of cool-season grass, mix 2.6 to 3.0 fluid ounces with 1 gallon of water. Should be used on weeds while they are actively growing.
  • Use 1.84 to 2.57 fl oz per 1 gallon of water to treat 1,000 square feet of warm-season grass. Spread on weeds when they’re still young and growing.
