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.
