Abstract

The present invention relates to methods for controlling or preventing infestation of cereal plants by the phytopathogenic microorganism Fusarium pseudograminearum , comprising applying to a crop of plants, the locus thereof, or seed thereof, a compound according to formula (I) wherein R1, R2, R3, R4, R5, Y, A, B are as defined herein.

Claims (33)

1. A method for controlling or preventing infestation of cereal plants by Fusarium pseudograminearum comprising applying to a crop of plants, the locus thereof, or seed thereof, a compound according to formula (Ic)

wherein R11 is C1, R12 is C1 and A is 2-trifluoromethyl-pyrid-3-yl or a tautomer or stereoisomer thereof.

2. The method according to claim 1 , wherein the compound according to formula (Ic) is applied to a seed.

3. The method according to claim 2 , wherein the rate of application to the seed is in the range of 0.002 and 0.03 mg of the compound according to formula (Ic) per seed.

4. The method according to claim 2 , wherein the seed is wheat or barley.

5. The method according to claim 2 , wherein the seed is wheat.

6. The method according to claim 5 , wherein the rate of application to the seed is in the range of 0.002 and 0.03 mg of the compound according to formula (Ic) per seed.

7. The method according to claim 5 , wherein the rate of application to the seed is in the range of 0.002 and 0.015 of the compound according to formula (Ic) AI per seed.

8. The method according to claim 1 , wherein the compound is applied to the crop of plants.

9. The method according to claim 8 , wherein the crop is wheat or barley.

10. The method according to claim 8 , wherein the crop is wheat.

11. The method according to claim 1 , wherein the compound is applied to the locus thereof.

12. The method according to claim 11 , wherein the crop is wheat or barley.

13. The method according to claim 11 , wherein the crop is wheat.

14. The method according to claim 1 , further comprising identifying a field under disease pressure from Fusarium pseudograminearum.

15. The method according to claim 14 , wherein identifying comprises taking soil samples.

16. The method according to claim 14 , wherein identifying comprises reviewing historical data of the field.

17. The method according to claim 14 , wherein the Fusarium pseudograminearum is resistant to other fungicides.

18. The method according to claim 1 , wherein yield in the crop is increased by at least about 26% compared to untreated control.

19. The method according to claim 18 , wherein disease is reduced by at least about 34% compared to untreated control.

20. The method according to claim 1 , wherein disease is reduced by at least about 34% compared to untreated control.

21. A method of producing a crop of cereal plants under disease pressure from Fusarium pseudograminearum , comprising:

identifying a field under disease pressure from Fusarium pseudograminearum;

treating a cereal seed with a seed treatment comprising, a compound according to formula (Ic)

wherein R11 is C1, R12 is C1 and A is 2-trifluoromethyl-pyrid-3-yl; and

cultivating the treated cereal seed in the field.

22. The method according to claim 21 , wherein the cereal seed is wheat.

23. The method according to claim 22 , wherein the compound according to formula (Ic) is treated to the seed at a rate of between 0.002 and 0.03 mg per seed.

24. The method according to claim 23 , wherein yield in the crop is increased by at least about 26% compared to untreated control.

25. The method according to claim 24 , wherein disease is reduced by at least about 34% compared to untreated control.

26. The method according to claim 23 , wherein disease is reduced by at least about 34% compared to untreated control.

27. The method according to claim 1 , wherein the compound of formula (Ic) is present in a ratio of greater than 4:1 compared to the enantiomer thereof.

28. The method according to claim 21 , wherein the compound of formula (Ic) is present in a ratio of greater than 4:1 compared to the enantiomer thereof.
