Quinclorac 75 DF Herbicide - 1 lb by Bottle by Prime Source

used double dose (2 tbsp/gal) and was ineffective on average crabgrass. So retreated with triple dose 3tbsp/gal. Ineffective. Noticed the date of manufacture and lot number was smudged out. This seller apparently sells old or outdated lawn chemicals. Not to be trusted.

I was happy to find this stronger crabgrass killer online while it's still available. Most products you see labeled to kill crabgrass have only tiny percentages of quincllorac in them, so you have to buy the product over and over, when you really are paying for the fertilizer or other types of herbicides in their mix. This is the concentrated dry granules that I will carefully measure out to mix with a gallon of water and surfactant to help it stick to the crabgrass. I hope I can kill the crabgrass that gets past the preemergent and wants to grow crazy in the summer heat. If you decide to go with this, it should last you a long time. Of course, using gloves, goggles and keeping pets off the treated area for the recommended time are necessary precautions.

This is an absolute fabulous product for killing crab grass in your yard. I simply follow the instructions on the label.

Package received with no damage.

easy to mix, using on thick crabgrass, appears to be working very well.

Works well in killing off crabgrass in a few days

This is a spot kill crabgrass killer one oz. per gal. but mix with one oz. per gal. of baby shampoo. It works better, it sticks to the crabgrass. Give it about four days you should see something happing. I also mixed food coloring about one oz. per gal. to see were I was spraying. Blue or Black works the best. It does not kill other weeds that I see.
