1. A composition comprising
(1) at least one compound of the formula (I)
wherein
R 1 represents a hydrogen atom or a methyl group and
R 2 represents a methyl group, a difluoromethyl group or a trifluoromethyl group; and
(2) at least one fungicide selected from (1.29) benzovindiflupyr,
(2.6) 3-(4,4-difluoro-3,3-dimethyl-3,4-dihydroisoquinolin-1-yl)quinolone according to formula (II-6)
and
(2.7) 2-{2-[(2,5-dimethylphenoxy)methyl]phenyl}-2-methoxy-N-methylacetamide.
2. A composition according to claim 1 , whereby the compound of formula (I) is represented by one of the compounds (I-1) to (I-5):
3. The composition according to claim 1 , whereby the compound of formula (I) is represented by formula (I-(R))
wherein
R 1 represents a hydrogen atom or a methyl group and
R 2 represents a methyl group, a difluoromethyl group or a trifluoromethyl group.
4. The composition according to claim 1 , whereby the compound of formula (I) is represented by formula (I-(S))
wherein
R 1 represents a hydrogen atom or a methyl group and
R 2 represents a methyl group, a difluoromethyl group or a trifluoromethyl group.
5. A method for controlling one or more harmful microorganisms, comprising contacting said one or more harmful microorganisms and/or a habitat thereof with a composition according to claim 1 .
6. A method for treating seeds, comprising contacting said seeds with a composition according to claim 1 .
7. A process for preparing a composition, comprising mixing a composition according to claim 1 with an extender, a surfactant or a combination thereof.
8. A process of claim 7 , wherein said composition comprises a synergistically effective mixture.
9. The composition according to claim 1 , wherein the compound of formula (I) is
