Abstract
Abstract Fungicidal or algicidal agents are provided which consist of a copper salt of an acid which is an unsaturated dibasic acid of the formula ∥ H--C--COOH wherein R is hydrogen or lower alkyl or is terephthalic acid or isophthalic acid together with an inorganic copper compound which is sparingly soluble or insoluble in water for example basic copper chloride, basic copper sulfate, basic copper carbonate, copper silicate, cuprous oxide, basic copper phosphate and copper hydroxide. The copper salt and the inorganic copper compound are preferably divided as finely as possible and thereafter mixed.
