Fungicidal compositions
View Patent ↗A composition suitable for control of diseases caused by phytopathogens comprising (A) a compound of Formula (I) wherein R 1 is difluoromethyl or trifluoromethyl and X is chloro, fluoro or bromo; and (B) at least one compound selected from compounds known for their fungicidal activity; and a method of controlling diseases on useful plants, especially rust diseases on soybean plants.
1. A composition suitable for control of diseases caused by phytopathogens comprising a synergistically effective amount of
(A) a compound of formula I
wherein R 1 is difluoromethyl or trifluoromethyl and X is chloro, fluoro or bromo; and
(B1) a strobilurin fungicide.
2. A composition according to claim 1 , wherein component (B1) is a fungicide selected from the group consisting of azoxystrobin, fluoxastrobin, picoxystrobin, pyraclostrobin, and trifloxystrobin.
3. A composition according to claim 1 , wherein component (B1) is a fungicide selected from the group consisting of azoxystrobin, fluoxastrobin, picoxystrobin, and pyraclostrobin.
4. A composition according to claim 1 , wherein component (A) is 3-difluoromethyl-1-methyl-1H-pyrazole-4-carboxylic acid (9-dichloromethylidene-benzonorbornene-5-yl)amide and component (B1) is selected from the group consisting of azoxystrobin and picoxystrobin.
5. A composition according to claim 1 , wherein component (A) is 3-difluoromethyl-1-methyl-1H-pyrazole-4-carboxylic acid (9-difluoromethylidene-benzonorbornene-5-yl)amide and component (B1) is azoxystrobin.
6. A composition according to claim 1 , wherein the weight ratio of (A) to (B1) is from 2000:1 to 1:1000.
7. A composition according to claim 1 , wherein component (A) is 3-difluoromethyl-1-methyl-1H-pyrazole-4-carboxylic acid (9-dichloromethylidene-benzonorbornene-5-yl)amide.
8. A method of controlling diseases on useful plants or on propagation material thereof caused by phytopathogens, which comprises applying to the useful plants, the locus thereof or propagation material thereof a composition according to claim 1 .
9. A method of controlling diseases on soybean plants caused by phytopathogens, which comprises applying to the soybean plants or to the locus thereof a composition according to claim 1 .
10. A method according to claim 9 , wherein the phytopathogen is Phakopsora pachyrhizi.
11. A method according to claim 10 , wherein the soybean plants are glyphosate tolerant and wherein the composition further comprises glyphosate.
12. A method according to claim 10 , wherein the composition is applied to the soybean plants or the locus thereof.
