Customer Reviews for Prime Source Quinclorac 75 DF Select Herbicide

I use this later in the crabgrass growing season if I missed some with the pre-emergent. Takes care of it with no problem.

Does an amazing job for spot treatment of post emergent crab grass. Better to avoid this issue with pre-emergent treatment, but when all else fails Quinclorac takes care of the problem, with crab grass dying within 1-2 weeks of application.

Started out using this for crabgrass but have since been using it for spot treating weeds. It works great on both. I fought crabgrass for a long time until finding Quinclorac and now the rest of the weeds get the pleasure of meeting it too.

mixed and used as instructed. Killing the crabgrass and also the torpedo grass. First thing I found that actually works.

It’s very effective. It kills almost all weeds with a couple of days. Unfortunately the crabgrass for which I bought this weed killer I’m still waiting for the result after 2 weeks of application, although I noticed some welting and discoloration of many leaves ends. I’ll try, as per the herbicide instruction, to reapply after 3 weeks of the first application. I noticed as well that it affected and welted my bermuda lawn in some small places.
