1. A method to improve germination of seeds and vitality of seedlings of an agricultural, vegetable or flower crop, comprising (i) hydrating, (ii) drying, and (iii) treating said seeds of the crop with a seed treatment containing at least one insecticidal, acaricidal or nematicidal compound, wherein the seedlings are selected from the group consisting of:
seedlings of Agricultural crops selected from the group consisting of: Beta, Brassica, Gossypium, and Zea; seedlings of Vegetable crops selected from the group consisting of: Allium, Brassica, Capsicum, Cucumis, Daucus, Lactuca, and Solanum; and seedlings of Flower crops selected from the group consisting of: Dianthus, Impatiens, Pelargonium, Petunia, Tageta, and Verbena, wherein the seeds are hydrated by hydropriming for 1 to 24 hours, at temperatures from 10° C. to 30° C., or drumprimed for 5 to 17 days, at temperatures from 10° C. to 30° C., or osmoprimed for 3 to 15 days, at temperatures from 10° C. to 30° C., with an osmotic potential of −0.5 to −2.6 MPa, or solid matrix primed for 3 to 15 days, at temperatures from 10° C. to 30° C., with an osmotic potential of −0.5 to −2.6 MPa, dried to a moisture content of 3 to 15% on a fresh weight basis, wherein said at least one compound is selected from the group consisting of: (1.1.1) clothianidin, (1.1.2) imidacloprid, (1.1.4) thiamethoxam, (5.2.1) fipronil and wherein the negative effect of the seed treatment on germination of seeds and vitality of seedlings is smaller or absent than a treating without (ii) drying prior to the treating. |
