  • Seed treating suspension and method of seed treatment
    Patent number: 4192095
    Abstract: Heavy coated seeds for crops such as rice are produced by application of an oleaginous suspension of a solid, inert water-insoluble inorganic particulate material in a discontinuous oil phase dispersed in a continuous water phase. The suspension is mixed with the seeds and the coated seeds are permitted to cure during absorption of the suspension components. The suspension remaining on the seed surfaces inverts and adheres to the surfaces to increase the weight of the seeds. The suspension comprises a continuous water phase, a discontinous oil phase, and a finely ground inert inorganic particulate material.
