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.
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.
