Abstract

The present invention relates to combinations of pyrimethanil, or a salt thereof, and a monoterpene, or a salt thereof, which provide an improved biocidal effect. More particularly, the present invention relates to compositions comprising a combination of pyrimethanil, or a salt thereof, together with a monoterpene selected from thymol and β-thujaplicin 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, viruses, and the like.

First claim

The invention claimed is:

1. A method of controlling microbial growth on wood, wood products and biodegrable materials, which comprises applying an antimicrobially effective amount of a composition comprising a combination of pyrimethanil as a component (I) and thymol as a component (II);
whereby component (I) and component (II) are in respective proportions to provide a synergistic biocidal effect, to the wood, wood products and biodegrable materials to be treated.

2. Method of controlling microbial growth on engineering materials, which comprises applying an antimicrobially effective amount of a composition comprising a combination of pyrimethanil as a component (I) and thymol as a component (II);
whereby component (I) and component (II) are in respective proportions to provide a synergistic biocidal effect, to the engineering materials to be treated.

3. Method of controlling microbial growth on plants, parts of plants, fruit and seeds, which comprises applying an antimicrobially effective amount of a composition comprising a combination of pyrimethanil as a component (I) and thymol as a component (II);
whereby component (I) and component (II) are in respective proportions to provide a synergistic biocidal effect, to the plants, parts of plants, fruit and seeds to be treated.
