Herbicidal compositions, methods of preparation and methods of use
First Claim
1. A composition of matter comprising glyphosate acid in admixture with a non-ionic surfactant, said surfactant comprising one or more polyglycolethers, each having a waxy consistency, and each polyglycolether comprising a linear saturated alcohol having from 10 to 15 carbon atoms, which is ethoxylated with from 30 to about 40 moles ethylene oxide per mole of alcohol.

Abstract
The present invention relates to a herbicidal composition that is in the form of solid water dispersible granules (WDG) containing the compound N-phosphonomethylglycine (glyphosate acid) in an admixture with a surfactant that is comprised of one or more polyglycolethers, each having a waxy consistency, and each polyglycolether having a linear saturated alcohol having from about 10 to about 15 carbon atoms, which is ethoxylated with from about 30 to about 40 moles of ethylene oxide per mole of alcohol. This composition provides a combination of manufacturing and weed killing (i.e., herbicidal) advantages that heretofore have been unattainable with the use of either glyphosate acid or glyphosate in salt form. The present invention also relates to methods of using this composition and a process for preparing the WDG composition that comprises mixing the glyphosate acid with the surfactant and then extruding the mixture.
