Combinations of fludioxonil with dipyrithione, 2-Pyridinol-1-oxide / 1-hydroxy-2-pyridone and their derivatives

摘要

Disclosed is a composition comprising a combination of the phenylpyrrole fludioxonil as component (I) and as component (II) a pyrion compound selected from 1-hydroxy-2-pyridinone (also known as 2-pyridinol-1-oxide or 1-hydroxy-2-pyridone), ciclopirox, ciclopirox olamine, piroctone, piroctone olamine, rilopirox, pyrion disulfide (also known as dipyrithione or omadine disulfide), sodium pyrithione or zinc pyrithione; wherein the ratio by weight of component (I) to component (II) ranges from 10: 1 to 1: 10 to provide a synergistic biocidal effect. Further disclosed is a method of controlling microbial growth on wood, wood products and biodegrable materials, which comprises applying an antimicrobially effective amount of a composition as defined above to the wood, wood products and biodegrable materials to be treated.
