Fungicide compositions comprising fluopyram, at least one succinate dehydrogenase (SDH) inhibitor and optionally at least one triazole fungicide
View Patent ↗The present invention relates to novel fungicide compositions comprising (A) fluopyram, (B) at least one further succinate dehydrogenase (SDH) inhibitor and optionally further (C) at least one triazole fungicide, whereas the invention especially comprises such novel fungicide compositions of (A) fluopyram, (B) bixafen and (C) at least one triazole fungicide, which is preferably prothioconazole. The present invention also relates to the use of such novel fungicide compositions for improving growth in crops, comprising preventively and/or curatively controlling pathogenic fungi and/or nematodes, resistance management, and improving plant physiology effects by enhancing root growth, improving greening, improving water use efficiency, improving nitrogen-use efficacy, delaying senescence and enhancing yield.

2. Composition comprising active compound combination according to claim 1 and further comprising one or more of auxiliaries, solvents, carriers, surfactants and/or extenders.
3. Method for improving growth in one or more crops, comprising applying an active compound combination according to claim 1 to seed, a plant, to fruit of a plant and/or to soil on which the plant grows or is supposed to grow, each including seed of a transgenic plant and/or a transgenic plant.
4. Method according to claim 3 , wherein improved growth comprises at least one selected from the group consisting of preventively and/or curatively controlling pathogenic fungi and/or nematodes, resistance management, and improved plant physiology effects selected from enhanced root growth, improved greening, improved water use efficiency, improved nitrogen-use efficiency, delayed senescence and enhanced yield.
5. Method according to claim 3 , wherein improved growth comprises at least one selected from the group consisting of better growth, increased harvest yields, a better developed root system, a larger leaf area, greener leaves and stronger shoots.
6. Method for improving growth in one or more crops comprising preventively and/or curatively controlling pathogenic fungi and/or nematodes,
comprising applying an active compound combination comprising
(A) fluopyram and
(B) bixafen and
(C) at least one triazole fungicide
to seed, a plant, to fruit of a plant and/or to soil on which the plant grows or is supposed to grow, each including seed of a transgenic plant and/or a transgenic plan
wherein preventive control of pathogenic fungi and/or nematodes is still observed when the seed or the plant is infested with pathogenic fungi and/or nematodes up to four weeks after application of the active compound combination.
7. Method according to claim 3 , wherein in treatment of leaves, from 0.1 to 10 000 g active compound combination/ha and in treatment of seed, from 2 to 200 g active compound combination per 100 kg of seed are employed.
8. A fungicidal composition comprising
(A) fluopyram and
(B) at least one further succinate dehydrogenase (SDH) inhibitor comprising biaxafen and further
(C) at least one triazole fungicide comprising prothioconazole
wherein the composition improves growth in one or more crops, wherein improvement comprises at least one selected from the group consisting of preventively and/or curatively controlling pathogenic fungi and/or nematodes, resistance management, and improved plant physiology effects selected from enhanced root growth, improved greening, improved water use efficiency, improved nitrogen-use efficiency, delayed senescence and enhanced yield.
9. A method according to claim 4 , wherein resistance management is improved and is defined as prevention and/or delay of development of insensitivity of pathogenic fungi to the fungicidal composition.
10. A method according to claim 4 , wherein pathogenic fungi are controlled which are selected from the group consisting of Tapesia/Oculimacula /Pseudocercosporella species, Septoria tritici, Leptosphaeria nodorum, Puccinia triticiana, Puccinia striiformis, Pyrenophora/Drechslera tritici - repentis, Blumeria graminis/Erysiphe graminis, Fusarium spp., Rhynchosporium secalis, Pyrenophora/Drechslera teres, Puccinia hordei , and Ramularia collo - cygni.
11. A method according to claim 3 comprising treatment of cereals selected from the group consisting of wheat and barley.
12. A method according to claim 6 , wherein the at least one triazole fungicide comprises prothioconazole.
13. A combination according to claim 1 , wherein compounds (A), (B), and (C) are present in a synergistically effective amounts and are the sole active compounds in the combination.
14. A combination according to claim 1 , wherein the weight ratios of A:B and B:C and A:C are independently each 10:1 to 1:10.
15. A combination according to claim 1 , wherein the weight ratios of A:B and B:C and A:C are independently each 5:1 to 1:5.
