Popis: An improved procedure is described for the estimation of benomyl (methyl 1-(butylcarbamoyl)-2-benzimidazole carbamate), folcidin (methyl [l-([(5-cyanopentyl) amino] carbonyl)-1H-benzimidazole-2-yI] carbamate), and thiabendazole ( 2-(4’-thiazolyl)-benzimidazole) in the concentration range of 0.1–1.0 mg/ml. Representative samples of the fungicides in aqueous suspension are shaken with a chloroform solution of cupric acetate and l-dimethylamino- 2-propanol (sodium hydroxide is added in the case of thiabendazole) to produce a green color in the chloroform phase. The analysis may be completed by spectrophotometric measurement or by comparison with described artificial standards.
