Review: Works well - Works great will buy again
Review: Excellent selective herbicide! - I bought this to eliminate weeds without harming our Buffalograss lawn. It’s very concentrated, so you have to mix it yourself in a sprayer- but that makes it an incredible value. I finally ran out of my first bottle, after about 5 years of use! The concentrate keeps fine, but once mixed you should use it quickly. I recommend adding a surfactant and dye, which will help it stick to the plants and show you where you’ve sprayed, which helps you save energy and supplies. It really feels like magic- it won’t harm the grass, but in a few days the weeds begin to lighten and eventually turn white and die!

## Questions & Answers

**Q: Why can it not be sold to those of us in the restricted states mentioned above?**
A: Pretty sure because they haven't applied for it to be registered. If it is the exact formula as Tenacity, then Tenacity is only restricted in AK and PR. There is another generic 40% mesotrione product restricted in less states than this Meso 4SC,  AK, AZ, CA, HI, and this one is ok for CA.

### ⭐⭐⭐⭐ On St Augustine vs oxalis: yes
*by C***F on March 31, 2022*

Okay, I've had a very tough lawn problem which, because I live in So. California, has been almost impossible to solve. The oxalis (kind of clover with little yellow flowers) has been coming in every winter and it has gotten so bad that you really can't see the St Augustine anymore. It all dies back by about April or May, but blocking the sunlight all winter is really done a terrible number on the grass. Anyway I finally decided I would try to get rid of it by whatever means necessary, except that most herbicides you can apply to St Augustine aren't available in California, and most of the things that are available in California you can't apply to St Augustine or don't kill oxalis. You see the catch 22 there? So this product says you really shouldn't apply it to St Augustine either, unless it's being grown "at a sod farm". Well that's puzzling to me I don't really get it, so I decided to take the risk cause I didn't have much to lose. I think the risk is it may turn your grass white. But that seems to be a temporary thing and the grass can come back. At any rate I sprayed it on at a point in Feb. at which you could really only see all the oxalis anyway. I hadn't mowed the lawn and at least 8 weeks to let the oxalis grow up above the grass. I tried not to get too much on the grass itself. About 3 weeks after the first application the oxalis had withered and turned kind of a yellow color but it was still there. So as directed I put on a second application. About 3 weeks after that and the oxalis is pretty well gone. So even though on the second application I got probably more of the product on the grass, the grass really wasn't harmed too much. It kind of is a bit on the pale side but not white, and even that is now starting to disappear and a deeper green is forming. It's been probably five weeks after the second application and the lawn is really looking great and there's very very few weeds of any kind in it. Pretty thrilled. So my basic message is, if you have St Augustine and you're at your wit's end you might as well try this even though the label says it's not a great idea. I really looked all over the Internet and couldn't find a good answer to this question.
