Abstract
This invention relates to bacteriostatic, fungistatic and algicidal compositions. Said compositions comprise a metal derivative of N-hydroxypyridinethione of the formula: ##STR1## in which R represents a hydrogen atom, a lower alkyl radical, a lower alkoxy radical or a halogenated lower alkyl radical, together with a compound selected from the haloborates and the halosilicates.
