Abstract: An encapsulated particle includes a core particle, a polyurethane layer, and a wax. The polyurethane layer is disposed about the core particle and the wax is disposed about the polyurethane layer. The polyurethane layer includes the reaction product of an isocyanate and a polyol component. The polyol component includes a catalytic polyol derived from an aromatic amine-based initiator and a polyether polyol that is different from the catalytic polyol in a weight ratio of from about 1:2 to about 10:1. A method of encapsulating the core particle includes the steps of providing the core particle, the isocyanate, the polyol component, and the wax. The method also includes the steps of mixing and reacting the isocyanate and the polyol component to form a polyurethane, encapsulating the core particle with the polyurethane layer which comprises the polyurethane, and encapsulating the polyurethane layer with the wax.

Abstract: An encapsulated particle comprises a core particle, a transferrable-pesticide disposed about the core particle, and a polyurethane layer disposed about the transferrable-pesticide. The core particle comprises a fertilizer, such as urea. The transferrable-pesticide can comprise a dinitroaniline, such as pendimethalin. The polyurethane layer is generally formed from a reaction mixture having a maximum temperature of no greater than about 30 °C. The polyurethane layer inhibits the transferrable-pesticide from transferring to a surface different from the core particle when the encapsulated particle physically contacts the surface. A method of forming the encapsulated particle comprises the steps of encapsulating the core particle with the transferrable-pesticide to form an intermediate-particle, combining an isocyanate and a polyol to form the reaction mixture, and encapsulating the intermediate- particle with the reaction mixture to form the polyurethane layer of the encapsulated particle. The polyurethane layer comprises the reaction product of the isocyanate and polyol.
