Quinclorac 75 DF Selective Herbicide 1lb

Why did you pick this product vs others?:Excellent mid season crabgrass killer

I used this for a couple of years on a yard war with wild violets. If you're infested with wild violets and you just have to get rid of them, this is what you need. Be aware of a couple of things.1. This will kill every wild violet it touches, if applied at the right time of year - late fall as the violets are prepping for winter.2. There is probably nothing under the violets, as they are very aggressive. So you may be left with bald areas in your lawn.3. Oh, here's a third. It works GREAT on gravel driveways to keep them clear of weeds, grasses, etc.

Quality herbicide, but you do need to get a methylated seed oil to mix with it to have it work per instructions. I wasn't aware of that until I was ready to mix it up and spray it. They should clearly add that to the listing. If you plan on using this, make sure to add some MSO to your purchase as well.

I was a little hesitant due to the cost to try this. After the first use I can say that I'm impressed at how quickly this kills crab grass. In 24 hours it was already dried up and brown. No damage to my Bermuda grass. I will definitely buy this again. Shipping was very fast too.

Within 2 days, all the crabgrass that was treated was noticeably dying and did not harm my lawn. It is easy to use and dissolves quickly. I recommend applying Quinclorac 75 DF before 12 noon, and to make sure that it adheres and remains on the crabgrass, use a Surfactant. After putting the two products and the correct amount of water in your pump sprayer, be sure to shake a little for everything to mix.

A distant second best compared to MSMA for crabgrass and invasive Saint Augustine control in a Bermuda lawn. With MSMA, full sun, no rain for a few days and with temps of ~80+ deg, I usually saw yellowing in about 2 days and after about a week, full results.With this product, it took almost a week before I saw some yellowing and after about two weeks, the crab grass and Saint Augustine is mostly still there. Based on appearance they seem to be in a mildly weakened state but far from gone and clawing their way back to health. I sprayed again, hope to see full results soon.Given that MSMA is no longer available outside of specific-use commercial applications, Quinclorac seems to be the only direct replacement for MSMA.I used the recommended mix rate of 1TBS of Quinclorac 75 DF, 2TBS of methylated seed oil as a surfactant mixed into 1GAL of water. It's recommended to fill the sprayer about half way, add the Quinclorac and methylated seed oil then fill the sprayer completely. Shake vigorously and then use - immediately.Once mixed and in a sprayer, it breaks down quickly after mixing. 24 hours seems to be the consensus. Best to mix only what you'll use right away. I'd suggest estimating how much you need, mix only half that much, mix more if needed. Anything left over will be wasted.I've read that this has a shelf life in the original container of 1-3 years IF it's stored in a cool, dry location and protected from direct sunlight. I'd suggest using a heavy duty, air tight plastic bag to place the container in, seal and store in your house if a climate controlled shed or garage isn't an option.Given that MSMA is no longer available outside of specific-use commercial applications, Quinclorac seems to be the only direct replacement for MSMA.This is my first experience with Quinclorac so my experience is limited. As time goes on, perhaps there are other ways of using this that might produce better results. I've read that it can be mixed with certain other herbicides and that there may be a synergistic effect. Definitely spend some time researching this product before purchase.

Tennessee yard guy here. Let me first say, I'm no lawn care expert at all. I've always been into yards though. A passion I inherited from my dad. When I got my first house, I knew I wanted to have a nice yard and I worked hard at maintaining that with fertilizer, weed control and mowing 2-3 times a week. It wasn't until after I found Youtube channels like Connor Ward and Ryan Knorr that I decided to truly get hardcore into it.I have a mixture of common Bermuda, Tifway Bermuda and some patches of Tall Fescue. Like everybody, weeds was always a constant battle. I've had mild success with your normal big box store weed killers, but I have always battled my dreaded nemesis, crabgrass. Seems like no matter what I used, hardly anything would really get rid of it. I used Fertilome, 2-4-d (one time, before I realized it wasn't for crabgrass), SedgeEnder to even MSMA. No matter what I did, crabgrass always reared its ugly face - until this past week.Quinclorac 75 DF is my godsend. I know there are some others out there like Tenacity. This was my first time dealing with a granular type herbicide that you mix with water so I was definitely a bit nervous because this stuff is not cheap. While I can not speak to why some maybe didn't have any success with this stuff, but for me it worked wonders. I literally received my order of Quinclorac this past Friday, got home from work and sprayed the yard that afternoon. I was scared that it wasn't going to work because the following morning on Saturday about 10-11am, it started raining all day. So it had less than 24 hours to sit on the turf as the instructions gave. By Sunday afternoon as I'm typing this up, just about all that I sprayed with Quinclorac is dead. I mean dead. Not turning purple, or yellow or red. Black. Dead. I have never seen anything work as fast as Quinclorac. I'm literally floored.I mostly did spot spraying, especially in my side and backyard. But my front yard was especially rough. I kind of had to spot spray and then also spray and pray because there was so much in certain places. I didn't kill it all, but I knew going in I was probably going to have to do a second round anyway for those that I may have missed as well as those that popped up after I sprayed. Quinclorac is not a pre-emergent.For those needing mixing instructions. It's 1 tablespoon per gallon of water (for 1000 sqft). Also you MUST use a surfactant. If not, I'm afraid you're going to be wasting your time. Quinclorac recommends MSO surfactant because its supposedly better at breaking into the weed and causing it to die. All I had was NIS. I put in 2 tablespoons according to Quinclorac's instructions for MSO. My NIS said 1 teaspoon per gallon, so I know I greatly overdid it. I also used some blue Turfmark so I could highlight what I had already sprayed. Fill half full of water, put your Quinclorac/Surfactant/Turfmark in, close it up and shake thoroughly for a good 15 seconds. Put your remaining water in. Close it up, shake it again and go spray. Do periodically shake it while you're out spraying to keep it circulating in your water.I'm not sure how long Quinclorac will last, but based on what I used, I feel like this stuff will last me a few years. If you have a crabgrass problem, I cannot more highly recommend Quinclorac. If it doesn't work for you, I would encourage you to check what surfactant you used. If it's NIS, give MSO a shot.
