Review: Works as described. - Works as described.
Review: Good price on good product. - If you spray certain herbicides, you need MSO, not generic NIS. MSO is a bit pricey, but this one makes the cost per ounce reasonable. And let's be real... Shelf life is very long, and if you spray much, you'll use it eventually. Don't get this if you have 1500 square feet, it'd last a couple generations!

## Features

- Works as a surfactant to help herbicides stick to the plant leaves.
- If using Quinclorac, MSO is recommended instead of a non ionic surfactant
