Abstract
A herbicidal solution contains from 30% by weight to saturation of a water soluble glyphosate salt and from 8 to 20% by weight of surfactant comprising from 10 to 100% by weight based on the total weight of surfactant of an amphoteric surfactant and from 0 to 90% by weight based on the total weight of surfactant of ether carobxylate, said solution containing less than 0.035% by weight of sodium ion. A pre-blended surfactant concentrate contains from 10 to 70% by weight ether carboxylate, from 20 to 80% by weight of low salt amphoteric surfactant and from 10 to 50% by weight of solvent.
