Abstract
Herbicidal compositions comprising high load aminophosphate or aminophosphonate salts, in particular high load glyphosate salts, wherein the compositions comprises a surfactant mixture of at least an C6-C22 amine oxide and a tertiary amine surfactants. The compositions have good low temperature stability (i.e., no crystal formulation or phase separation) among other beneficial properties.
