Abstract From the Canadian patent

By the present invention, a surfactant system containing glyphosate has been created which can be used to yield formulations containing an ultra-high load of glyphosate, in which the glyphosate concentration is higher than previously possible in any agriculturally-acceptable formulation. Higher loadings are desirable to reduce shipping and container costs as well as reduce wastes. , The higher loading reduces storage requirements and allows the farmer to handle less volume of pesticide. The main advantage is that maximizing the loading minimizes the cost to deliver the active ingredient which in turn , maximizes economy in use of glyphosate.
