MSO Concentrate is a surfactant for use with various herbicides to improve their performance. Surfactants help the herbicide to “stick” to the plant and thus it is more readily absorbed, leading to improved performance of the herbicide in killing targeted weeds. Surfactants are strongly encouraged when using some herbicides such as quinclorac.

Application Rate: 1-2 pints per acre

Minimum of 20 gallons of spray per acre.


Always read and follow label directions when using any herbicide product.
