Primes Source Quinclorac 75 DF Logo
Quinclorac 75 DF Select™ is a selective, post-emergent herbicide that can be safely applied to many types of turf to control a variety of broadleaf and grassy weeds. Quinclorac 75 DF Select can be applied to both residential and non-residential turf. Quinclorac 75 DF Select can be applied from 7 days before seeding and up to 28 days after emergence on selected weeds. The use of a methylated seed oil, such as Duo Stick Select is recommended to greatly enhance the effectiveness of the product.

    Maximum Yearly Limits
     DO NOT apply more than 2 pounds of Quinclorac Select 75 DF Herbicide per acre (or 0.73 oz per 1000 sq ft) in one year (1.5 lbs ai per acre per year).
    Mowing Instructions
    Mowing Information. DO NOT mow 2 days before or after applying Quinclorac Select 75 DF Herbicide to maximize weed control and minimize potential turf injury. Clippings from the first three mowings should be left on the treated area.
    Water Instructions
     If soil moisture is not sufficient prior to Quinclorac Select 75 DF Herbicide application, irrigation may improve weed control. For best results, DO NOT water or irrigate for 24 hours after application. If rainfall does not occur in 2 to 7 days after application, irrigation of at least 1/2 inch is required.
    Before Seeding Instructions
    The use of Quinclorac Select 75 DF Herbicide before or after seeding or overseeding a turf area will not significantly interfere with the turfgrass seed germination and growth of those grass types identified as tolerant or moderately tolerant in Table 1 on the label. Consult Table 4 on the label for timing of applications concerning any seeding, overseeding or sprigging situation.
