Abstract

The invention relates to the use of diamines of the formula I ##STR1## in which R and R.sup.1 are, for example, identical and are alkyl, as active substances for the control of harmful organisms in water and other materials, especially industrial materials. Inter alia, bacteria, fungi, yeasts and algae are controlled. The control is effected in standing and running waters. In preservatives and disinfectants, the diamines are used for natural and synthetic materials, especially industrial materials.
