Synergistic fungicidal active substance combinations
View Patent ↗Novel active compound combinations comprising a carboxamide of the general formula (I) (group 1) in which A, R 1 , R 2 and R 3 are as defined in the description, and the active compound groups (2) to (23) listed in the description have very good fungicidal properties.
1. A composition comprising the carboxamide (1-1) N-(3′,4′-dichloro-5-fluoro-1,1′-biphenyl-2-yl)-3-(difluoromethyl)-1-methyl-1H-pyrazole-4-carboxamide and at least one triazole selected from the group consisting of
(3-3) propiconazole,
(3-12) epoxiconazole,
(3-17) tebuconazole, and
(3-21) bitertanol,
in a ratio of 20:1 to 1:20 of carboxamide to triazole.
2. A composition according to claim 1 , wherein the carboxamide and triazole are present in a synergistic ratio.
3. A composition according to claim 1 , wherein the carboxamide and triazole are present in a 1:1 ratio.
4. A composition comprising the carboxamide (1-1) N-(3′,4′-dichloro-5-fluoro-1,1′-biphenyl-2-yl)-3-(difluoromethyl)-1-methyl-1H-pyrazole-4-carboxamide and (3-15) prothioconazole in a ratio of 10:1 to 1:20 of carboxamide (1-1) to (3-15) prothioconazole.
5. The composition according to claim 4 , wherein the carboxamide (1-1) and (3-15) prothioconazole are present in a synergistic ratio.
6. The composition according to claim 4 , wherein the carboxamide (1-1) and (3-15) prothioconazole are present in a 1:1 ratio.
7. A method for controlling unwanted phytopathogenic fungi, comprising applying the composition according to claim 1 to the unwanted phytopathogenic fungi and/or their habitat.
8. A process for preparing fungicidal compositions, comprising mixing the composition according to claim 1 with extenders and/or surfactants.
9. A method for controlling unwanted phytopathogenic fungi, comprising applying the composition according to claim 4 to the unwanted phytopathogenic fungi and/or their habitat.
10. A process for preparing fungicidal compositions, comprising mixing the composition according to claim 4 with extenders and/or surfactants.
