Abstract:
A herbicidal aqueous solution consisting essentially offrom 30% by weight of said solution to saturation of water soluble glyphosate salt; from 8 to 20% by weight of said solution of surfactant, said surfactant comprising from 10 to 100% by weight based on the total weight of said surfactant of an amphoteric surfactant and from 10 to 90% by weight based on the total weight of surfactant of ether carboxylate, said solution has less than 0.035 % of sodium ion; and wherein said amphoteric surfactant is betaine of the formula RR12N+CH2COOâˆ’ wherein R is an alkyl, alkenyl or alkyl phenyl group having 6 to 20 aliphatic carbon atoms and each R1 is an alky or hydroxyalkyl group having from 1 to 4 carbon atoms; and optionally a sequestrant and optionally up to 20% by weight nonionic wetting agent.
