    • The present invention provides seed coating systems and methods for their use, where a seed coating system comprises encapsulated active ingredient particles that comprise an active ingredient and an encapsulation layer with a preselected release profile, and a polymeric seed coating, wherein the polymeric seed coating releasably affixes the encapsulated active ingredient particle in proximity to a surface of a seed. In embodiments, the seed coating system comprises a plurality of active ingredient layers, wherein a first active ingredient layer comprises a first encapsulated active ingredient, wherein the first encapsulated active ingredient is encapsulated in a first polymer, and wherein the polymer comprises a first binding site that binds the active ingredient and a second binding site for binding to a delivery area, and a binder to releasably affix the encapsulated active ingredient to at least one of a seed surface or a second active ingredient layer, and wherein a second active ingredient layer comprises a second encapsulated active ingredient, wherein the second encapsulated active ingredient is encapsulated in a second polymer which may be the same as or different from the first polymer, and a binder to releasably affix the encapsulated active ingredient to at least one of the first active ingredient layer and a subsequent active ingredient layer.
    • 本发明提供种子包衣系统及其使用方法,其中种子包衣系统包含包含活性成分的包封的活性成分颗粒和具有预选释放特征的包封层和聚合种子包衣,其中可释放的聚合种子包衣 将包封的活性成分颗粒粘附在种子表面附近。 在实施方案中,种子包衣系统包含多个活性成分层,其中第一活性成分层包含第一包封的活性成分,其中所述第一包封的活性成分包封在第一聚合物中,并且其中所述聚合物包含第一结合位点 其结合活性成分和用于结合至递送区域的第二结合位点,以及将包封的活性成分可释放地粘贴到种子表面或第二活性成分层中的至少一种的粘合剂,并且其中第二活性成分层包含 第二包封的活性成分,其中所述第二包封的活性成分包封在可与所述第一聚合物相同或不同的第二聚合物中,以及粘合剂,以将所述包封的活性成分可释放地贴附至所述第一活性成分中的至少一种 层和随后的活性成分层。
