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 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.

2. The composition as claimed in claim 1 wherein the ratio by weight of component (I) to component (II) ranges from 10:1 to 1:10.

3. The composition as claimed in claim 2 wherein the ratio by weight of component (I) to component (II) ranges from 4:1 to 1:4.

4. The composition according claim 1 wherein the amount of component (I) is present in a range from 10 to 50.000 mg/I and the amount of component (II) is present in a range from 10 to 50.000 mg/I.

5. A product containing
(a) a composition comprising pyrimethanil as a component (I); and
(b) a composition comprising as a component (II) a monoterpene compound is thymol, as a combination for simultaneous or sequential use, wherein said compositions (a) and (b) are in respective proportions to provide a synergistic biocidal effect.
