본 발명은 비수성 용매계; 10 wt% 이하 양의 적어도 하나의 설포닐우레아 제초제; 및 2 이상의 계면활성제를 포함하는 제초액 조성물에 관한 것으로; 액체 조성물내 계면활성제의 총량의 80 wt% 내지 100 wt%는 클래스 1-14에서 선택된 계면활성제로 구성되고; 2종 이상의 상이한 클래스 1-14는 각각 액체 조성물내 계면활성제 총량의 10wt% 이상을 차지한다. 본 발명자들은 상이한 클래스로부터의 2개 이상의 계면활성제의 조합이 사용되고, 액체 조성물내 계면활성제 총량의 상당량이 확인된 클래스의 계면활성제로 만들어진다면, 안정화제가 없는 경우에도 설포닐우레아의 열화를 크게 줄이거나 없앨 수 있음을 발견했다. 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.
