Composition and method for improving plant health
The present invention relates to plant-protecting active ingredient mixtures comprising, as active components, a neonicotinoid and one or two fungicides selected from pyraclostrobin and boscalid, in synergistically effective amounts and to a method of improving the health of plants by to the plants or the locus thereof by applying said mixtures.
1. A pesticidal mixture comprising, as active components, a neonicotinoid, pyraclostrobin and metalaxyl, in synergistically effective amounts.
2. The pesticidal mixture according to claim 1 , in which each combination of two ingredients in the mixture of three ingredients ranges from 100:1 to 1:100.
3. The pesticidal mixture according to claim 1 , wherein the neonicotinoid is thiamethoxam.
4. The pesticidal mixture according to claim 1 , wherein the neonicotinoid is clothianidin.
5. The pesticidal mixture according to claim 1 , wherein the neonicotinoid is imidacloprid.
6. The pesticidal mixture according to claim 1 , wherein the neonicotinoid is acetamiprid.
7. A method of improving the health of plants, which comprises applying in any desired sequence, including simultaneously, separately, in succession, or as a mixture, a synergistically effective amount of a neonicotinoid, pyraclostrobin and metalaxyl.
8. The method as claimed in claim 7 , wherein the amount of the neonicotinoid, pyraclostrobin and metalaxyl or the mixture thereof applied is from 0.1 g/ha to 2000 g/ha.
9. The method of claim 7 , in which each combination of two ingredients in the mixture of three ingredients ranges from 100:1 to 1:100.
10. The method of claim 8 , wherein the neonicotinoid is thiamethoxam, clothianidin, imidacloprid, or acetamiprid.
11. A method of controlling or preventing fungal infestation in plants, parts of plants, seeds, or at their locus of growth, which comprises applying in any desired sequence, including simultaneously, separately, succession, or as a mixture, a synergistically effective amount of a neonicotinoid, pyraclostrobin and metalaxyl.
12. The method as claimed in claim 1 , wherein the amount of the neonicotinoid, pyraclostrobin and metalaxyl or the mixture thereof applied is from 0.1 g/ha to 2000 g/ha.
13. The method of claim 12 , in which each combination of two ingredients in the mixture of three ingredients ranges from 100:1 to 1:100.
14. The method of claim 12 , wherein the neonicotinoid is thiamethoxam, clothianidin, imidacloprid, or acetamiprid.
15. A method of protection of seeds comprising contacting the seeds before sowing and/or after pregermination with a mixture as defined in claim 1 in synergistically effective amounts.
16. The method of claim 15 , wherein the mixture is applied in an amount from 0.1 g/ha to 2000 g/ha.
17. The method of claim 16 , in which each combination of two ingredients in the mixture of three ingredients ranges from 100:1 to 1:100.
18. The method of claim 16 , wherein the neonicotinoid is thiamethoxam, clothianidin, imidacloprid, or acetamiprid.
19. A plant propagation material treated with the mixtures of claim 1 in an amount of from 0.1 g to 5 kg per 100 kg of seeds.
20. The plant propagation material of claim 19 , wherein the propagation material is seeds.
21. The propagation material of claim 19 , in which each combination of two ingredients in the mixture of three ingredients ranges from 100:1 to 1:100.
22. The propagation material of claim 20 , wherein the neonicotinoid is thiamethoxam, clothianidin, imidacloprid, or acetamiprid.
