PrimesourceMeso 4 SC Select with Yield Titan's Vector Blue Concentrated Spray Pattern Indicator 8 Ounces and Surfactant

It’s so frustrating to read the reviews saying the product doesn’t work. This is a professional grade chemical and it seems people are just trying to spray it on a weed and hope it dies. Mesotrione is most beneficial when seeding new grass as it is one of the only herbicides that can provide pre emergence of select weeds while you are germinating grass. Although it does have post emergent properties, it has to be sprayed at the correct rate, with the correct amount of non-ionic surfactant and most of the time requires split applications at the recommended intervals. It annoys me that people are buying strong stuff like this and not even reading the label on the bottle before applying it to their yards. Please, please do your full research and read the label before applying any herbicide. Your lawn, the environment, your children and your pets will thank you.Also if you mix Mesotrione with other broadleaf herbicides like Speedzone, you greatly increase its post emergent capacity. This ensures that the weeds die and don’t develop Mesotrione resistance.

I read reviews about the blue dye being hard to see. First batch I mixed per instructions. Couldn’t see any blue. Second batch I used more dye. Still couldn’t blue on grass. Later batches I skipped the blue dye.The weed killer works great though.

The product arrived a day earlier than expected in a completely sealed package that also included a syringe to measure the necessary dose of herbicide with a scale of teaspoons at the top and gallons at the bottom. This makes it very easy to know the necessary amount of herbicide for your sprayer. The Vector dye works very well as long as you pour the suggested amount per gallon of the product (6 teaspoons/gal) which is quite a lot. I found that the usage instructions for both the Vector dye and the Surfactant are practically illegible due to the small font size. A few days after applying the herbicide in my yard, I am already seeing the weeds turning white without affecting how my Bermuda grass looks. I hope this can help everyone

I purchased this generic form of Tenacity as I know many people really like using tenacity for its pre- and post emergent effects. Tenacity will start turning the weed white as it kills the crabgrass or other weeds in the lawn. However, I mixed this up in my sprayer and even added a little extra the second time I used this. So far, this hasn't killed any of the weeds in my back yard. They are still growing and thriving. I may have received a bad bottle or possibly this generic brand just doesn't work. Who knows. I am leary to try it again.Also, I added the dye marker to the mix as well. It was almost near impossible to see the dye on my lawn and was pretty much useless.

(3 stars for Customer service) was good and prompt! Told them that my syringe that came with the package tip was broken so they immediately sent out a new one for me. However, I didn't like how the big syringe only could fit in one of the 3 containers. Even though I like how it says how many teaspoons easy to read. Used it 2-3 times on my yard and has shown no improvements on the yard. Instead MORE weeds!!! Followed the directions and everything right. May work for others but not for our yard.

Very effective herbicide for crabgrass. What you see on the pictures is day five, but I started to see the discoloration on the third day. Some of my lawn grass (4th photo) seems to have a little bit of bleaching as well, but I read that it’s expected, and should go away after two or three mows. I’m excited to see the end result (meaning thick, lush lawn with no weeds). I’ll try to update in a month or so.

This is good value for getting the three solutions necessary for spraying the clover that has taken hold in my lawn. It's convenient to have them all together and I hope to only need this a few times, so the amounts should be sufficient.The directions are very small on the bottles, but the process is fairly simple to mix the three liquids in your sprayer using the included syringe. There are several YouTube videos that will demonstrate the process.I'm several weeks out from application, and the clover is turning white and dying out, as expected I am hoping one more application in the spring to remove the last of it.

I guess I should have checked the fluid ounces of each bottle, they look like the bigger versions I have bought before. The products are good, just the quatity is an issue.
