  • Stable, dry compositions for use as herbicides
    Patent number: 6071858
    Abstract: 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-thiadia zol-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-thiadia zol-2-yl]oxy]acetamide in the composition is from about 1:1 to about 1:6.
