Abstract
The present invention relates to an aqueous suspended agricultural chemical composition wherein component (a) is ethyl(R)-2-[4-(6-chloroquinoxalin-2-yloxy)phenoxy]propionate of which the ratio of β-type crystal is 80% by weight or more, component (b) is surfactant and component (c) is water. An aqueous suspended agricultural chemical composition of the invention has good flowability and the growth of quizalofop-p-ethyl particle is small, resulting in high preservation stability under severe preservation condition.
Claims14
A method for improving preservation stability of an aqueous suspended agricultural chemical composition, comprising:
- adding ethyl(R)-2-[4-(6-chloroquinoxalin-2-yloxy)phenoxy]propionate, wherein at least 80%, by weight, of the ethyl(R)-2-[4-(6-chloroquinoxalin-2-yloxy)phenoxy]propionate is present in a β-type crystal form;
- adding surfactant;
- and
- adding water.
