Will Quinclorac 75 DF Herbicide injure or kill centipede turfgrass? Will turfgrass recover after an application?
I sprayed my centipede lawn with Quinclorac. It has turned yellow. Will it recover?

When using Quinclorac 75 DF, optimal control may not be achieved when treating crabgrass at the 2-4 tiller stage. Sequential applications may be necessary when treating during that stage. For best results, you should use a methylated seed oil with the Quinclorac 75 DF either before the 2nd tiller stage, or on mature crabgrass. The amount of time you will need to wait to reseed after applying Quinclorac 75 DF will depend on the type of seed you are using. Please refer to the seeding chart on p. 11 of the product label for specific timing.

The product label for Quinclorac 75 DF does not restrict applications during transition. However, since Quinclorac 75 DF may yellow hybrid Bermudagrass, and Bermuda in general is more sensitive during transition, we recommend that you wait until the Bermuda is fully green before applying this herbicide. Quinclorac will be most effective when air temperatures are around 60-85 degrees and there is good soil moisture, so those conditions may not exist until the Bermuda is fully green. You can add some chelated iron or liquid nitrogen fertilizer when using Quinclorac 75 DF on hybrid Bermuda to help reduce risk of discoloration, per the product label.

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.
