STABLE SOLUTIONS OF HERBICIDAL N-ALKOXY-N'-ALKYL SUBSTITUTED N-PHENYLUREAS

摘要

Solutions of herbicidal N'-alkoxy-N'-alkyl-N-substituted phenyl-ureas which are stable over a wide temperature range including temperatures down to -10.degree.C are disclosed. The solvents are mixtures of (A) dimenthylformamide, dimethylacetamide or dimethylsulphoxide and (B) a solvent miscible with solvent A even though it is not per se a solvent for the N-phenylureas but excluding alcohols, aliphatic acids and aliphatic hydrocarbons.
