The present invention relates to combinations of hydroxypyrion compounds, and silver compound which provide an improved biocidal effect. More particularly, the present invention relates to compositions comprising a combination of a hydroxypyrion compound selected from 1-hydroxy-2-pyridinone, ciclopirox, ciclopirox olamine, piroctone, piroctone olamine, rilopirox, or a salt thereof, together with one or more silver salts selected from silver acetate, silver alginate, silver azide, silver citrate, silver lactate, silver nitrate, silver perchlorate, silver sulfate, silver chloride, silver thiocyanate, silver-sodium-hydrogen-zirconium phosphate, silver sulfadiazine, silver cyclohexanediacetic acid and disilver 2,5-dichloro-3,6-dihydroxy-2,5-cyclohexadiene-1,4-dione in respective proportions to provide a synergistic biocidal effect. Compositions comprising these combinations are useful for the protection of any living or non-living material, such as crops, plants, fruits, seeds, objects made of wood, thatch or the like, engineering material, biodegradable material and textiles against deterioration due to the action of microorganisms such as bacteria, fungi, yeasts, algae, virusses, and the like.
