Agrisel QuinKill Crabgrass and Weed Killer

QuinKill Max is a selective herbicide, meaning it is formulated to target specific weeds like crabgrass while leaving most established turf grasses unharmed. However, it is always wise to test a small, inconspicuous area first if you have a sensitive or non-standard grass variety.

The standard application rate is 3 tablespoons of concentrate per 1 gallon of water. This mixture covers approximately 1,000 square feet when applied as a spot treatment.

Yes, this is a post-emergent herbicide. It is specifically designed to eliminate crabgrass and other grassy weeds that have already emerged and are actively growing in your lawn.

QuinKill Max is formulated primarily for spot treatment. While it can be used for broader areas, its concentrated nature and specific active ingredient are most efficient and cost-effective when applied directly to the patches of weeds you want to remove.

While results can vary based on weather conditions and the maturity of the weeds, you will typically begin to see signs of yellowing or wilting on the targeted weeds within a week or two of application.
