Abstract

A combination comprising a multi-site contact fungicide, a first systemic fungicide and optionally a second systemic fungicide and a method using the same.

First claim

The invention claimed is:

1. A method for treating soybean rust in a host leguminous plant, wherein the method comprises treating the plant at the locus of the infection with mancozeb; and concurrently, prior, or subsequently with at least one quinone outside inhibitor and at least one demethylation inhibitor.

2. The method of claim 1 , wherein:
the quinone outside inhibitor is selected from fenamidone, famoxadone, and a strobilurin fungicide selected from the group consisting of azoxystrobin, mandestrobin, coumoxystrobin, enoxastrobin, flufenoxystrobin, pyraoxystrobin, dimoxystrobin, enestrobin, fluoxastrobin, kresoxim-methyl, metominostrobin, orysastrobin, picoxystrobin, pyrametostrobin, triclopyricarb, fenaminstrobin, pyraclostrobin and trifloxystrobin; and
the demethylation inhibitor is selected from triflumizole, triforine, pyridinitrile, pyrifenox, fenarimol, nuarimol, triarimol and a conazole fungicide selected from the group consisting of climbazole, clotrimazole, imazalil, oxpoconazole, prochloraz, prochloraz-manganese, triflumizole, azaconazole, bitertanol, bromuconazole, cyproconazole, diclobutrazol, difenoconazole, diniconazole, diniconazole-M, epoxiconazole, etaconazole, fenbuconazole, fluotrimazole, fluquinconazole, flusilazole, flutriafol, furconazole, furconazole-cis, hexaconazole, imibenconazole, ipconazole, metconazole, myclobutanil, pencoconazole, propiconazole, prothioconazole, quinconazole, simeconazole, tebuconazole, tetraconazole, triadimefon, triadimenol, triticonazole, uniconazole, perfurazoate, and uniconazole-P.

3. The method of claim 1 , wherein:
the quinone outside inhibitor is a strobilurin fungicide selected from trifloxystrobin, picoxystrobin, azoxystrobin, or pyraclostrobin; and
the demethylation inhibitor is a conazole fungicide selected from prothioconazole, cyproconazole, epoxiconazole, metconazole, and tebuconazole.

4. The method of claim 3 , wherein:
the strobilurin fungicide is trifloxystrobin and the conazole fungicide is prothioconazole;
the strobilurin fungicide is picoxystrobin and the conazole fungicide is tebuconazole;
the strobilurin fungicide is picoxystrobin and the conazole fungicide is cyproconazole;
the strobilurin fungicide is azoxystrobin and the conazole fungicide is cyproconazole;
the strobilurin fungicide is pyraclostrobin and the conazole fungicide is epoxiconazole;
the strobilurin fungicide is pyraclostrobin and the conazole fungicide is tebuconazole;
the strobilurin fungicide is pyraclostrobin and the conazole fungicide is metconazole;
the strobilurin fungicide is trifloxystrobin and the conazole fungicide is cyproconazole, propiconazole, or tebuconazole.

5. A fungicidal combination consisting of mancozeb, at least one quinone outside inhibitor, and at least one demethylation inhibitor.

6. The fungicidal combination of claim 5 , wherein the
the quinone outside inhibitor is selected from fenamidone, famoxadone, and a strobilurin fungicide selected from the group consisting of azoxystrobin, mandestrobin, coumoxystrobin, enoxastrobin, flufenoxystrobin, pyraoxystrobin, dimoxystrobin, enestrobin, fluoxastrobin, kresoxim-methyl, metominostrobin, orysastrobin, picoxystrobin, pyrametostrobin, triclopyricarb, fenaminstrobin, pyraclostrobin and trifloxystrobin; and
the demethylation inhibitor is selected from triflumizole, triforine, pyridinitrile, pyrifenox, fenarimol, nuarimol, triarimol and aconazole fungicide selected from the group consisting of climbazole, clotrimazole, imazalil, oxpoconazole, prochloraz, prochloraz-manganese, triflumizole, azaconazole, bitertanol, bromuconazole, cyproconazole, diclobutrazol, difenoconazole, diniconazole, diniconazole-M, epoxiconazole, etaconazole, fenbuconazole, fluotrimazole, fluquinconazole, flusilazole, flutriafol, furconazole, imibenconazole, ipconazole, furconazole-cis, metconazole, hexaconazole, myclobutanil, pencoconazole, propiconazole, prothioconazole, quinconazole, simeconazole, tebuconazole, tetraconazole, triadimefon, triadimenol, triticonazole, uniconazole, perfurazoate, and uniconazole-P.

7. The fungicidal combination of claim 5 , consisting of:
mancozeb;
a strobilurin fungicide selected from trifloxystrobin, picoxystrobin, azoxystrobin, or pyraclostrobin; and
a conazole fungicide selected from prothioconazole, cyproconazole, epoxiconazole, metconazole, and tebuconazole.

8. The fungicidal combination of claim 5 , wherein:
the strobilurin fungicide is trifloxystrobin and the conazole fungicide is prothioconazole;
the strobilurin fungicide is picoxystrobin and the conazole fungicide is tebuconazole;
the strobilurin fungicide is picoxystrobin and the conazole fungicide is cyproconazole;
the strobilurin fungicide is azoxystrobin and the conazole fungicide is cyproconazole;
the strobilurin fungicide is pyraclostrobin and the conazole fungicide is epoxiconazole;
the strobilurin fungicide is pyraclostrobin and the conazole fungicide is tebuconazole;
the strobilurin fungicide is pyraclostrobin and the conazole fungicide is metconazole; or
the strobilurin fungicide is trifloxystrobin and the conazole fungicide is cyproconazole, propiconazole, or tebuconazole.
