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, boscalid and a neonicotinoid selected from the group consisting of acetamiprid, thiamethoxam, and clothianidin in a weight ratio of from 100:1 to 1:100.
2. The pesticidal mixture according to claim 1 , wherein the neonicotinoid is thiamethoxam.
3. A method of improving the health of plants, which comprises applying boscalid and a neonicotinoid selected from the group consisting of acetamiprid, thiamethoxam, and clothianidin in a weight ratio of from 100:1 to 1:100, simultaneously, jointly, separately, or in succession.
4. A method as claimed in claim 3 , wherein the mixture is applied in an amount of from 0.1 g/ha to 2000 g/ha.
5. A method of controlling or preventing fungal or insecticidal infestation in plants, parts of plants, seeds, or at their locus of growth, which comprises applying boscalid and a neonicotinoid selected from the group consisting of acetamiprid, thiamethoxam, and clothianidin in a weight ratio of from 100:1 to 1:100, simultaneously, jointly, separately, or in succession.
6. A method of protection of seeds comprising contacting the seeds before sowing and/or after pregermination with the mixture as defined in claim 1 in a synergistically effective amount.
7. A method as claimed in claim 6 wherein the mixture is applied in an amount of from 0.1 g to 5 kg per 100 kg of seeds.
8. A plant propagation material treated with the mixtures as defined in claim 1 .
9. The plant propagation material of claim 8 , wherein seeds are the propagation material.
10. A seed treated with the mixture as claimed in claim 1 in an amount of from 0.1 g to 5 kg per 100 kg of seeds.
