Abstract
The present invention is directed to novel suspension concentrate compositions comprising finely milled crystalline sulfentrazone suspended in an aqueous glyphosate salt phase containing a surfactant component that chemically and physically stabilizes the composition.
Claims10
A suspension concentrate composition containing no volatile organic compounds comprising:
- i) crystalline sulfentrazone;
- ii) an aqueous glyphosate salt phase;
- and
- iii) a surfactant component comprising:
- an amine salt of alkylbenzenesulfonic acid,
- a methyl oleoyl taurate salt, and
- an alkyl polyglycoside.

A suspension concentrate composition containing no volatile organic compounds comprising:
- i) crystalline sulfentrazone present in an amount of from 5% to 7% by weight of all the components in the total composition;
- ii) an aqueous glyphosate salt phase, comprising a 62% aqueous solution of the isopropylamine salt of glyphosate, present in an amount of 40% to 50% by weight of all the components in the total composition;
- and
- iii) a surfactant component comprising:
- an amine salt of alkylbenzenesulfonic acid present in an amount of from 0.7% to 1% by weight of all the components in the total composition,
- a methyl oleoyl taurate salt present in amount of from 2.7% to 3.0% by weight of all the components in the total composition, and
- an alkyl polyglycoside present in an amount of from 0.8% to 1% by weight of all of the components in the total composition.
