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.

L'invention concerne un procédé permettant d'améliorer la vitesse de germination de semences de plantes traitées par un pesticide. Ledit procédé consiste à former un enrobage polymère sans pesticide sur une semence avant de la traiter à l'aide d'un pesticide, le type de polymère et l'épaisseur de l'enrobage étant conçus afin de bloquer le contact phytotoxique du pesticide avec ladite semence tout en permettant un transfert d'oxygène suffisant pour maintenir sa viabilité et un transfert d'humidité suffisant dans des conditions environnementales normalement rencontrées par la semence une fois qu'elle a été plantée pour germer; et à traiter la semence enrobée à l'aide d'un pesticide. L'invention concerne également les semences traitées au moyen de ce procédé et les plantes qui ont poussé à partir des semences traitées.
