Polyvinylimidazoline flocculants are converted to an easily handled granular form by pelletizing with siliceous material and a lower alcohol, or mixture of lower alcohols with esters or ketones, and subsequently drying the pellets.

Granular flocculants and their manufacture

Fungicidal or algicidal agents are provided which consist of a copper salt of an acid which is an unsaturated dibasic acid of the formula ##STR1## wherein R is hydrogen or lower alkyl 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 a finely as possible and thereafter mixed. The compositions are of low toxicity, provide a lasting effect and do not give rise generally to secondary noxious products.

Fungicidal/algicidal composition for non-medical uses

Fungicidal or algicidal agents are provided which consist of a copper salt of an acid which is an unsaturated dibasic acid of the formula
