Abstract
Phytotherapeutic compositions comprising diethylene glycol ether solutions of 2-(2-ethoxy)ethoxyethyl benzimidazolecarbamate are prepared by: (a) heating and agitating an opaque, fluid suspension of methyl 1-(butylcarbamoyl)-2-benzimidazolecarbamate and dimethylsulfoxide until the fluid clarifies whereby the butylcarbamoyl group is removed from the carbamate; (b) adding methanol to the clarified fluid to precipitate a paste containing methyl 2-benzimidazolecarbamate and methanol; (c) separating the supernatant fluid from the paste; and (d) admixing diethyleneglycol monoethyl ether with the paste to form a fluid slurry and heating the slurry, with agitation, until it clarifies to thereby obtain a diethylene glycol monoethyl ether solution of 2-(2-ethoxy)ethoxyethyl benzimidazolecarbamate, and thereafter diluting the solution with diethylene glycol monoethyl ether to obtain suitable use concentrations of the carbamate. The phytotherapeutic compositions are useful as an aid in the control of plant fungus disease.
