Abstract

The present invention relates to the use of novel oxadiazoles of the formula I or an N-oxide and/or their agriculturally useful salts for controlling phytopathogenic fungi, or to a method for combating phytopathogenic harmful fungi, which process comprises treating the fungi or the materials, plants, the soil or seeds to be protected against fungal attack, with an effective amount of at least one compound of formula I or an N-oxide or an agriculturally acceptable salt thereof; and to agrochemical compositions comprising at least one such compound and to agrochemical compositions further comprising seeds.

Claims

1-10. -10. (canceled)

11. An agrochemical composition comprising an auxiliary and a compound of formula I

12. The composition of claim 11, wherein A is phenyl.

13. The composition of claim 11, wherein W is NR¹R².

14. The composition of claim 11, wherein Y is O.

15. The composition of claim 11, wherein W is NR¹R² and R¹ is hydrogen, C₁-C₆-alkyl, C₂-C₆-alkenyl or C₂-C₆-alkynyl and R² is phenyl-C₁-C₄-alkyl, heteroaryl-C₁-C₄-alkyl, phenyl or heteroaryl;

and wherein the heteroaryl group is a 5- or 6-membered aromatic heterocycle, wherein the ring includes besides carbon atoms 1, 2, 3 or 4 heteroatoms selected from N, O and S as ring member atoms; and

wherein any of the above-mentioned aliphatic or cyclic groups are unsubstituted or substituted by 1, 2, 3 or up to the maximum possible number of identical or different groups R^1a.

16. The composition of claim 11, wherein W is NR¹R² and wherein R¹ and R² independently of each other are hydrogen, C₁-C₆-alkyl, C₂-C₆-alkenyl, C₂-C₆-alkynyl, C₃-C₆-cycloalkyl, C₃-C₆-cycloalkenyl;

and wherein the alicyclic and the cyclic groups are unsubstituted or substituted by 1, 2, 3 or up to the maximum possible number of identical or different groups R^1a.

17. The agrochemical composition according to claim 11 further comprising at least one further pesticidally active substance.

18. The agrochemical composition according to claim 11 further comprising seed, wherein the amount of the compound of the formula I, or an N-oxide, or an agriculturally acceptable salt thereof, is from 0.1 g to 10 kg per 100 kg of seed.

19. A method for combating phytopathogenic harmful fungi comprising treating fungi or materials, plants, soil or seeds to be protected against fungal attack, with an effective amount of the composition of claim 11.

20. The method of claim 19, wherein A is phenyl.

21. The method of claim 19, wherein W is NR¹R².

22. The method of claim 19, wherein Y is O.

23. The method of claim 19, wherein W is NR¹R² and R¹ is hydrogen, C₁-C₆-alkyl, C₂-C₆-alkenyl or C₂-C₆-alkynyl and R² is phenyl-C₁-C₄-alkyl, heteroaryl-C₁-C₄-alkyl, phenyl or heteroaryl;

and wherein the heteroaryl group is a 5- or 6-membered aromatic heterocycle, wherein the ring includes besides carbon atoms 1, 2, 3 or 4 heteroatoms selected from N, O and S as ring member atoms; and

wherein any of the above-mentioned aliphatic or cyclic groups are unsubstituted or substituted by 1, 2, 3 or up to the maximum possible number of identical or different groups R^1a.

24. The method of claim 19, wherein W is NR¹R² and wherein R¹ and R² independently of each other are hydrogen, C₁-C₆-alkyl, C₂-C₆-alkenyl, C₂-C₆-alkynyl, C₃-C₆-cycloalkyl, C₃-C₆-cycloalkenyl;

and wherein the alicyclic and the cyclic groups are unsubstituted or substituted by 1, 2, 3 or up to the maximum possible number of identical or different groups R^1a.
