## Abstract

Microbicide composition for plants, containing at least two active ingredient components in an amount producing synergistic activity, together with an appropriate filler, characterised in that component I is the compound 2-[α-{[(α-methyl-3-trifluoromethyl-benzyl)imino]-oxy}-o-tolyl]-yoxylic acid-methylester-O-methyloxime, and component II is a compound selected from the group IIA) 5,7-dichloro-4-(4-fluorophenoxy)quinoline (“Quinoxyfen”); IIB) 4-cyclopropyl-methyl-N-phenyl-2-pyrimidinamine (“Cyprodinil”); IIC) benzo(1,2,3)thiadiazole-7-carbothio-acid-S-methylester (“Acibenzolar-S-methyl”); IID) 3-anilino-5methyl-5(4-phenoxyphenyl)-1,3-oxazolidine-2,4-ione (“Famoxadone”); IIE) 8-(1,1-dimethylethyl)-N-ethyl-N-propyl-1,4-dioxaspiro[4.5]decane-2-methanamine (“Spiroxamin”); IIF) 4-(2,2-difluoro-1,3-benzodioxol-4-yl)pyrrole-3-carbonitrile (“Fludioxonil”); IIG) 4-(2,3-dichlorophenyl)pyrrole-3-carbonitrile (“Fenpiclonil”); IIH) 1-methyl-cyclohexanecarboxylic acid-(2,3-dichloro-4-hydroxy-phenyl)-amide (“Fenhexamid”); IIJ) 2-{2-[6-(2-cyano-phenoxy)-pyrimidin-4-yloxy]-phenyl}-3-methoxy-acrylic acid methyl ester (“Azoxystrobin”); IIK) Methoximino-(2-o-tolyloxymethyl-phenyl)-acetic acid methyl ester (“Kresoxim-methyl”); or repectively one of the salts or metal complexes of components I and II.

## Claims

### Claim 1

A microbicide composition for plants, containing at least two active ingredient components in an amount producing synergistic activity, together with an appropriate filler, characterised in that component I is the compound 2-[α-{[(α-methyl-3-trifluoromethyl-benzyl)imino]-oxy}-o-tolyl]-glyoxylic acid-methylester-O-methyloxime, and component 11 is a compound selected from the group 5,7-dichloro-4-(4-fluorophenoxy)quinoline (“Quinoxyfen”) and 4-cyclopropyl-6-methyl-N-phenyl-2-pyrimidinamine (“Cyprodinil”) or respectively one of the salts or metal complexes of components I and II, and wherein the weight ratio of component I to component II is from 20:1 to 1:20.

### Claim 2 (depends on 1)

The composition of claim 1, wherein component II is 5,7-dichloro-4-(4 fluorophenyoxy)quinoline.

### Claim 3 (depends on 1)

The composition of claim 1, wherein component II is 4-cyclopropyl-6-methyl-N-phenyl-2-pyrimidinamine.

### Claim 4 (depends on 1)

A method for the control and prevention of plant diseases, characterized in that a site which has been attacked by fungi or is in danger of being attacked by fungi is treated with a microbicidally effective amount of component I and component II according to claim 1 in any order or simultaneously.
