Abstract
The present invention relates to stable glyphosate formulations with improved efficacy by a highly effective alkoxylated alkylamine quaternary surfactant at a very low used level. The alkoxylated alkylamine quaternary surfactant is compatible in all salts of glyphosate formulations (including potassium and ammonium) even at very high concentration (470-600 g a.e./l).
