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 mancozeb, chlorothalonil, pyraclostrobin, fluoxastrobin, azoxystrobin, trifloxystrobin, picoxystrobin, and kresoxim-methyl provides synergistic control of selected fungi.

First claim

What is claimed:

a fungicidally effective amount of the compound of Formula I:

and at least one additional fungicide selected from the group consisting of chlorothalonil, mancozeb, folpet, and captan.

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

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

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

5. The synergistic fungicidal mixture of claim 4 , wherein the concentration ratio of the compound of Formula I to folpet is from 1:272 to 1:219.

6. The synergistic fungicidal mixture of claim 1 , wherein the concentration ratio of the compound of Formula I to chlorothalonil is 1:219.

7. The synergistic fungicidal mixture of claim 1 , wherein the concentration ratio of the compound of Formula I to mancozeb is 1:272.

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

9. 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 chlorothalonil, mancozeb, folpet, and captan.

10. The method of claim 9 , wherein the at least one additional fungicide is folpet.

11. The method of claim 10 , wherein the concentration ratio of the compound of Formula I to folpet is from 1:272 to 1:219.

12. The method of claim 9 , wherein the concentration ratio of the compound of Formula I to chlorothalonil is 1:219.

13. The method of claim 9 , wherein the concentration ratio of the compound of Formula I to mancozeb is 1:272.

14. The method of claim 9 , wherein the fungal pathogen is leaf blotch of wheat ( Mycosphaerella graminicola; anamorph: Septoria tritici ).

15. The method of claim 9 , 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. 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 ).

16. 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 pyraclostrobin, fluoxastrobin, azoxystrobin, trifloxystrobin, picoxystrobin, and kresoxim-methyl.

17. The synergistic fungicidal mixture of claim 16 , wherein the at least one additional fungicide is pyraclostrobin.

18. The synergistic fungicidal mixture of claim 16 , wherein the at least one additional fungicide is azoxystrobin.

19. The synergistic fungicidal mixture of claim 16 , wherein the concentration ratio of the compound of Formula I to picoxystrobin is from 1:30 to 1:2.6.

20. The synergistic fungicidal mixture of claim 16 , wherein the concentration ratio of the compound of Formula I to trifloxystrobin is from 1:9.7 to 4:1.

21. The synergistic fungicidal mixture of claim 16 , wherein the concentration ratio of the compound of Formula I to azoxystrobin is from 1:4.6 to 2:1.
