PLANT GROWTH REGULATORS - A01C: PLANTING; SOWING; FERTILISING (parts, details or accessories of agricultural machines or implements, in general A01B51/00 - A01B75/00) ## Abstract A coated seed obtained by coating a seed with a coating material containing an inorganic mineral powder and a thermosetting resin powder having an average particle diameter of 10 to 200 μm, wherein the thermosetting resin powder is a thermosetting resin powder obtained by aggregating a powdery pesticide with a thermosetting resin has an excellent quality. ## Claims ### Claim 1 A coated seed comprising a seed and a coating material comprising an inorganic mineral powder and a thermosetting resin powder, wherein the amount of the coating material is 3 to 200 kg based on 1 kg of the seed, the thermosetting resin powder has an average particle diameter of 10 to 200 μm and is obtained by aggregating a powdery pesticide with a thermosetting resin, and the powdery pesticide comprises an amount of pesticidally active component that is effective to protect a crop germinated from the seed against a disease or pest without causing significant chemical injury to the crop. ### Claim 2 (depends on 1) The coated seed according to claim 1, having an average particle diameter of 1 to 20 mm. ### Claim 3 (depends on 1) The coated seed according to claim 1, wherein the coating material comprises 10 to 99.5 wt % of the inorganic mineral powder and 0.5 to 90 wt % of the thermosetting resin powder. ### Claim 4 (depends on 3) The coated seed according to claim 3, wherein the coating material further comprises 5 to 30 wt % of a water repellent agent. ### Claim 5 (depends on 1) The coated seed according to claim 1, wherein the thermosetting resin powder comprises 10 to 90 wt % of the pesticidally active component. ### Claim 6 (depends on 5) The coated seed according to claim 5, wherein the thermosetting resin is a urethane resin. ### Claim 7 (depends on 1) The coated seed according to claim 1, wherein the amount of the pesticidally active component in 1 kg of the coating seed is 5 to 200 g. ### Claim 8 (depends on 1) The coated seed according to claim 1, wherein the powdery pesticide comprises clothianidin. ### Claim 9 (depends on 1) The coated seed according to claim 1, wherein the seed is a seed of genus Brassica crops, genus Lactuca crops or Solanaceous crops. ### Claim 10 (depends on 1) The coated seed according to claim 1, wherein the seed is a long-shaped seed. ### Claim 11 (depends on 1) The coated seed according to claim 1, wherein the seed is a seed having a particle diameter of 1.0 to 4.0 mm. ### Claim 12 (depends on 2) The coated seed according to claim 2, wherein the coating material comprises 10 to 99.5 wt % of an inorganic mineral powder and 0.5 to 90 wt % of a thermosetting resin powder. ### Claim 13 (depends on 12) The coated seed according to claim 12, wherein the coating material further comprises 5 to 30 wt % of a water repellent agent. ### Claim 14 (depends on 1) The coated seed according to claim 1, wherein the thermosetting resin powder is obtained by a procedure comprising: (a) mixing the powdery pesticide with a first liquid component to obtain a mixture, wherein the first liquid component comprises a first raw material of the thermosetting resin; (b) adding a second liquid component to the mixture, wherein the second liquid component comprises a second raw material of the thermosetting resin; (c) allowing the first liquid component to react with the second liquid component to generate the thermosetting resin, thereby obtaining a powdery pesticide thermosetting resin solidified material; and (d) further adding the first liquid component and the second liquid component to the powdery pesticide thermosetting resin solidified material to coat the material with the thermosetting resin, thereby obtaining the thermosetting resin powder. ### Claim 15 (depends on 1) The coated seed according to claim 1, wherein the coating material further comprises calcium stearate. ### Claim 16 (depends on 1) The coated seed of claim 1, wherein the thermosetting resin is selected from the group consisting of a urethane resin, a urea resin, a urethane-urea resin, and an epoxy resin.
