    摘要: The present invention relates to a dry composition that can be used as a herbicide. The composition contains N-(4-fluorophenyl)-N-(1-methylethyl)-2-[[5-(trifluoromethyl)-1,3,4-thiadiazol-2-yl]oxy]acetamide, 4-amino-6-(1,1-dimethylethyl)-3-(methylthio)-1,2,4-triazin-5-(4H)-one, and a pH adjusting agent. The pH adjusting agent is present in an amount such that it constitutes from about 0.1% to about 10% of the composition, and the resulting pH is from about 2.8 to about 5.4. The molar ratio of 4-amino-6-(1,1-dimethylethyl)-3-(methylthio)-1,2,4-triazin-5-(4H)-one to N-(4-fluorophenyl)-N-(1-methylethyl)-2-[[5-(trifluoromethyl)-1,3,4-thiadiazol-2-yl]oxy]acetamide in the composition is from about 1:1 to about 1:6.

    摘要: The present invention relates to an improved process for the preparation of an acyl derivative of O,S-dialkyl phosphoroamidothioate by reacting an O,S-dialkyl phosphoroamidothioate with an acylating agent in the presence of an acid, wherein the improvement resides in adding a C.sub.4 to C.sub.8 aliphatic alcohol, following completion of the acylation reaction, to the mixture of the N-acyl-O,S-dialkyl phosphoroamidothioate, the acylating agent and the acid. In an embodiment of the present invention, the acylation reaction is conducted in the absence of a solvent. The aliphatic alcohol is easily recovered and can be reused in a subsequent acylation reaction.
