Kill new crabgrass
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.
