Abstract: The present invention relates to a liquid herbicidal composition comprising: a non-aqueous solvent system; at least one sulfonylurea herbicide in an amount of 10 wt. % or less; and two or more surfactants; and characterized in that: 80 wt. % to 100 wt. % of the total amount of surfactant in the liquid composition is made up of surfactants selected from the surfactant classes 1-14 as described herein; and at least two different surfactant classes 1-14 each account for at least 10 wt. % of the total amount of surfactant in the liquid composition. The inventors have found that, if a combination of two or more surfactants from the different surfactant classes are employed, and if a significant portion of the total amount of surfactant in the liquid composition is made of surfactants from the identified surfactant classes, then degradation of the sulfonylurea can be greatly reduced or eliminated, even in the absence of a stabilising agent.
