Maneb, zineb, mancozeb, and arbitrarily selected mixtures of those can be differentiated by a simple method. Compounds are differentiated on the basis of colors produced after treatment of saturated solutions of the fungicides in n-propanol-acetone mixture (1 + 1 v/v), first with dithizone and then with monosodium dihydrogen phosphate solution in the same solvent. The color depends on the type and concentration of metal present in the sample.
代森锰、代森锌、代森锰锌以及这些药剂的任意选定混合物可以通过一种简单方法加以区分。这些化合物是根据杀菌剂在正丙醇 - 丙酮混合物（1 + 1 v/v）中的饱和溶液，先用双硫腙处理，然后再用同一溶剂中的磷酸二氢钠溶液处理后所产生的颜色来区分的。颜色取决于样品中存在的金属类型和浓度。
