Will the effectiveness of Quinclorac 75 DF Herbicide be reduced if I watered the application in after the initial treatment? I mixed 24 oz of Quinclorac 75 DF Herbicide with 4 gallons of water.


Per the product label, if soil is dry before a Quali-Pro Quinclorac 75 DF application, irrigation of the turfgrass may improve weed control. For best results, DO NOT water or irrigate for 24 hours following the application. Irrigate the treated turfgrass with atleast ½ inch of water 2 to 7 days after application if no rainfall is received within that period.  Depending on how many square feet the 4 gallons of mixed solution covered, you may need to do a repeat application for better weed control. Per the product label, the mix rate is 0.73 oz per 1000 sq ft or 1 tbsp per gallon of water.
