Abstract

Compounds of formula (I) are as defined in the claims, and their use in compositions and methods for the control and/or prevention of microbial infection, particularly fungal infection, in plants and to processes for the preparation of these compounds.

First claim

The invention claimed is:

1. A compound of Formula I-a

wherein
R a is H;
R b is fluorine, chlorine, methyl or ethyl; and
R c is H, fluorine, chlorine, bromine; and
R is H, C 1-5 -alkyl, C 1-5 -alkylacyl, acetyl, formyl,

 or an agronomically acceptable salt, stereoisomer, diastereoisomer, enantiomer, tautomer, atriopisomer or N-oxide thereof.

2. A composition for controlling and protecting against phytopathogenic microorganisms, comprising a compound of formula I-a as defined in claim 1 and at least one auxiliary.

3. A composition comprising a fungicidally effective amount of a compound of formula I-a as defined in claim 1 , optionally comprising at least one additional active ingredient.

4. A compound of formula (I)

wherein
R a is H;
R b is fluorine, chlorine;
R c =H, fluorine, chlorine, C 1 -C 2 alkoxy or C 1 -C 2 haloalkoxy; and
R is ethyl, methyl, propargyl, C(O)R′; wherein R′ is C 2 -C 6 alkyl; and wherein R does not form a ring with either R b or R c ;
or an agronomically acceptable salt, stereoisomer, diastereoisomer, enantiomer, tautomer, atriopisomer or N-oxide thereof.

5. A compound of formula (I) according to claim 4 , wherein
R a is H;
R b is chlorine or fluorine;
R c =H, fluorine or chlorine; and
R is ethyl, methyl or propargyl.

6. A compound of formula (I) according to claim 4 , wherein the compound of formula (I) has the formula I-b

wherein
R a is H;
R b is fluorine, chlorine;
R c =H, fluorine, chlorine; and
R is H, C 2 -C 6 alkyl.

7. A method of controlling or preventing infestation of useful plants by phytopathogenic microorganisms, wherein a compound of formula I-a as defined in claim 1 as active ingredient, is applied to the plants, to parts thereof or the locus thereof.

8. A method of controlling phytopathogenic diseases on useful plants or plant propagation material thereof, which comprises applying to said plant propagation material a fungicidally effective amount of a plant propagation material protecting composition comprising a compound of formula I-a as defined in claim 1 together with a suitable carrier therefor.
