Abstract

A fungicidal composition containing a fungicidally effective amount of the compound of Formula I:

5-fluoro-4-imino-3-methyl-1-tosyl-3,4-dihydropyrimidin-2(1H)-one, and at least one fungicide selected from the group consisting of fluxapyroxad, benzovindiflupyr, penthiopyrad, isopyrazam, boscalid, and fluopyram provides synergistic control of selected fungi.

First claim

What is claimed:

1. A synergistic fungicidal mixture, comprising:
a fungicidally effective amount of the compound of Formula I:

and at least one additional fungicide selected from the group consisting of fluxapyroxad, benzovindiflupyr, penthiopyrad, isopyrazam, bixafen, boscalid, penflufen and fluopyram.

2. The synergistic fungicidal mixture of claim 1 , wherein the at least one additional fungicide is selected from the group consisting of fluxapyroxad, benzovindiflupyr, penthiopyrad, isopyrazam, boscalid, and fluopyram.

3. The synergistic fungicidal mixture of claim 2 , wherein the concentration ratio of the compound of Formula I to fluxapyroxad is from 4.4:1 to 6.3:1.

4. The synergistic fungicidal mixture of claim 2 , wherein the concentration ratio of the compound of Formula I to benzovindiflupyr is from 1:3 to 7.9:1.

5. The synergistic fungicidal mixture of claim 2 , wherein the concentration ratio of the compound of Formula I to penthiopyrad is from 1:4.3 to 1:1.9.

6. The synergistic fungicidal mixture of claim 2 , wherein the concentration ratio of the compound of Formula I to isopyrazam is from 1:1.3 to 1:1.

7. The synergistic fungicidal mixture of claim 2 , wherein the concentration ratio of the compound of Formula I to boscalid is from 1:13.2 to 1:1.3.

8. The synergistic fungicidal mixture of claim 2 , wherein the concentration ratio of the compound of Formula I to fluopyram is from 1:27.6 to 1:3.6.

9. The synergistic fungicidal mixture of claim 1 , wherein the at least one additional fungicide is fluxapyroxad.

10. The synergistic fungicidal mixture of claim 1 , wherein the at least one additional fungicide is penthiopyrad.

11. The synergistic fungicidal mixture of claim 1 , wherein the at least one additional fungicide is benzovindiflupyr.

12. The synergistic fungicidal mixture of claim 1 , wherein the at least one additional fungicide is fluopyram.

13. The synergistic fungicidal mixture of claim 1 , wherein the at least one additional fungicide is isopyrazam.

14. The synergistic fungicidal mixture of claim 1 , wherein the at least one additional fungicide is boscalid.

15. A synergistic fungicidal composition comprising a fungicidally effective amount of the synergistic fungicidal mixture of claim 1 and an agriculturally acceptable adjuvant or carrier.

16. A method for the control of fungal pathogen attack on a plant, the method comprising: applying to a plant a synergistic fungicidal mixture, comprising a fungicidally effective amount of the compound of Formula I:

and at least one additional fungicide selected from the group consisting of fluxapyroxad, benzovindiflupyr, penthiopyrad, isopyrazam, bixafen, boscalid, penflufen and fluopyram.

17. The method of claim 16 , wherein the at least one additional fungicide is selected from the group consisting of fluzapyroxad, benzovindiflupyr, penthiopyrad, isopyrazam, boscalid, and fluopyram.

18. The method of claim 17 , wherein the concentration ratio of the compound of Formula I to fluxapyroxad is from 4.4:1 to 6.3:1.

19. The method of claim 17 , wherein the concentration ratio of the compound of Formula I to benzovindiflupyr is from 1:3 to 7.9:1.

20. The method of claim 17 , wherein the concentration ratio of the compound of Formula I to penthiopyrad is from 1:4.3 to 1:1.9.

21. The method of claim 17 , wherein the concentration ratio of the compound of Formula I to isopyrazam is from 1:1.3 to 1:1.

22. The method of claim 17 , wherein the concentration ratio of the compound of Formula I to boscalid is from 1:13.2 to 1:1.3.

23. The method of claim 17 , wherein the concentration ratio of the compound of Formula I to fluopyram is from 1:27.6 to 1:3.6.

24. The method of claim 16 , wherein the fungal pathogen is leaf blotch of wheat ( Mycosphaerella graminicola; anamorph: Septoria tritici ).

25. The method of claim 16 , wherein the fungal pathogen is selected from the group consisting of leaf blotch of wheat ( Mycosphaerella graminicola ; anamorph: Septoria tritici ), wheat brown rust ( Puccinia triticina), stripe rust ( Puccinia striiformis f. sp. tritici ), scab of apple ( Venturia inaequalis ), blister smut of maize ( Ustilago maydis ), powdery mildew of grapevine ( Uncinula necator ), barley scald ( Rhynchosporium secalis ), blast of rice ( Magnaporthe grisea ), rust of soybean ( Phakopsora pachyrhizi ), glume blotch of wheat ( Leptosphaeria nodorum ), powdery mildew of wheat ( Blumeria graminis f. sp. tritici ), powdery mildew of barley ( Blumeria graminis f. sp. hordei ), powdery mildew of cucurbits ( Erysiphe cichoracearum ), anthracnose of cucurbits ( Glomerella lagenarium ), leaf spot of beet ( Cercospora beticola ), early blight of tomato ( Alternaria solani ), and net blotch of barley ( Pyrenophora teres ).
