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 synergistically effective amounts of:
(A) (1-1) N-(3′,4′-dichloro-5-fluoro-1,1′-biphenyl-2-yl)-3-(difluoromethyl)-1-methyl-1H-pyrazole-4-carboxamide and
(B) at least one active compound selected from the group consisting of:
(2-1) azoxystrobin,
(2-2) fluoxastrobin,
(2-4) trifloxystrobin,
(2-11) picoxystrobin, and
(2-12) pyraclostrobin,
wherein the weight ratio of (A) to the at least one active compound of (B) is from 10:1 to 1:20.
2. The composition of claim 1 , wherein the at least one active compound of (B) is (2-1) azoxystrobin.
3. The composition of claim 1 , wherein the at least one active compound of (B) is (2-2) fluoxastrobin.
4. The composition of claim 1 , wherein the at least one active compound of (B) is (2-4) trifloxystrobin.
5. The composition of claim 1 , wherein the at least one active compound of (B) is (2-11) picoxystrobin.
6. The composition of claim 1 , wherein the at least one active compound of (B) is (2-12) pyraclostrobin.
7. The composition of claim 1 , wherein (A) and the at least one active compound of (B) are the only active agents in the composition.
8. The composition of claim 1 , wherein (A) and the at least one active compound of (B) are the only anti-fungal agents in the composition.
9. A method for controlling unwanted phytopathogenic fungi, comprising applying the composition of claim 1 to the unwanted phytopathogenic fungi, their habitat, or combinations thereof.
10. A process for preparing a fungicidal composition, comprising mixing the composition of claim 1 with an extender, a surfactant, or combinations thereof.
