Q4 Plus Turf Herbicide - With Four Active Ingredients - 32 fl oz Bottle by PBI-Gordon

I'm using this to kill all the weeds and grass in our yard so we can start fresh with grass seed. This can also be used to spot kill any weeds or kill your entire lawn, you do need to be careful and follow the instructions closely. This is a concentrate and a little goes a long way, we used a pump sprayer so did not need to use a hose attachment. We did get some on the concrete but it did not seem to harm it. The shipper sealed the container to prevent leakage and added stamp on the bag that the bag contained a liquid. The instructions are clear, precise and easy to follow.

Absolutely the best of all the post-emergent herbicides i have tried You can see it working on the crabgrass in a day or two. As for some of the other stuff like clover and spurge it might take a little longer or another application in 30 days

This product I had emailed about to kill the wild onions. This was suggested and has killed all of them within a week. I highly recommend.

Works great! Fair price. Delivered in two days. Great experience.

Worked solid. Need more

This stuff works great. My neighbor told me about it. I am using on my many clumps of crabgrass and wild violets.

Works great to kill weeds

did great on broad leaf type weeds, however it did not even wilt the nutsedge

Never heard back from them when I wanted to return this!!

Dont waste your money! After years of using another popular name brand (Hi-Yield 2 4-D), we were urged to try this new, more expensive herbicide on our half acre. Followed instructions and applied in early Spring with no rain in forecast. Killed existing weeds, but they seemed to come back even more after old ones died off! We've now applied this 3 times since May and have had terrible results!! New and more abundant weeds seem to be populating!! In years past we only had to use our herbicides once and were weed free until the following Spring! So disappointed and alot of money wasted on a product with zero results. Just goes to show some times the cheaper products work best!
