Solid compositions of a liquid surfactant and a pyrazolium herbicide

摘要

There are provided solid herbicidal compositions comprising a molecular dispersion of a liquid non-ionic surfactant in herbicidal 1,2-dimethyl-3,5-diphenylpyrazolium salts, and wherein said compositions may optionally contain inert water-soluble bulking/absorbing agents. There is also provided a method for preparing said compositions by: (a) admixing same at room temperature and then melting said mixture at elevated temperatures; or (b) melting together all components of said compositions at elevated temperatures; and then following either of the above procedures, rapidly cooling said melt to obtain the aforementioned compositions.
