Abstract
A method of improving germination rate in pesticide-treated plant seeds involves forming a pesticide-free polymer coating on a plant seed before treating the seed with a pesticide, where the type of polymer and the coating thickness are designed to block phytotoxic contact of the pesticide with the seed while allowing sufficient transfer of oxygen to maintain the seed's viability and sufficient transfer of moisture under environmental conditions normally encountered by the seed after planting to enable its germination; and then treating the coated plant seed with a pesticide. Seeds that have been treated by this method, and plants that are grown from the treated seeds are also described.
