    • Water-dispersible, extruded granules for delivering agricultural chemicals, such as pesticides or non-pesticidal materials, to a crop. The granules are extrusion-formed from a blended composition including at least one active chemical ingredient, a solid carrier, and a binder. The active chemical ingredient may or may not be micro-encapsulated. The binder may be added directly to the composition or applied as a coating to the granules after the extrusion process. The binder reduces attrition, chemical volatility, and phytotoxicity. The granules are applied to a crop field by aerial means. The dense granules display good vertical drop characteristics, with little drift. If the crop field has standing water, the water-dispersible granules sink and break up, effecting dispersion of the chemical ingredient. When applied to a dry field, the subsequent exposure to water to the granules effects the same dispersal of chemical ingredient.
    • 用于将农药(例如农药或非农药)递送到作物的水分散性挤出颗粒。 颗粒由包含至少一种活性化学成分,固体载体和粘合剂的共混组合物挤出形成。 活性化学成分可以是或不是微胶囊化的。 粘合剂可以直接加入到组合物中,或者在挤出过程之后作为涂层涂覆到颗粒上。 粘合剂减少了磨损,化学挥发性和植物毒性。 颗粒通过天线方式施加到作物田地。 致密颗粒显示出良好的垂直下落特性,几乎没有漂移。 如果农作物田间存在水分,则水分散性颗粒会沉淀并分解,从而影响化学成分的分散。 当应用于干燥田地时,随后将水暴露于颗粒物会产生相同的化学成分分散。

    • Controlled release of one or more agricultural chemicals is provided by microcapsules adapted to rupture in a magnetic field. The microcapsules, which may be applied to soil, seeds and/or plants, each have a shell that encapsulates an agricultural chemical, such as a fertilizer, herbicide or insecticide. One or more organosilane-coated magnetic nanoparticles is/are covalently bound into the shell of each microcapsule. For example, (3-aminopropyl)trimethylsilane-coated magnetite nanoparticles may be incorporated into the shell of a urea-formaldehyde (UF) microcapsule during in situ polymerization. In one embodiment, microcapsules encapsulating a fertilizer are applied during seed planting. Controlled release is subsequently triggered after an appropriate period of dormancy by positioning a magnetic field generating device proximate the microcapsules to generate a magnetic field sufficient to rupture the microcapsule shells through magnetic stimulation of the organosilane-coated magnetic nanoparticles. The ruptured microcapsule shells release the fertilizer.
    • 一种或多种农药的控制释放由适于在磁场中破裂的微​​胶囊提供。 可以施用于土壤,种子和/或植物的微胶囊各自具有包封农业化学品如肥料,除草剂或杀虫剂的壳。 一个或多个有机硅烷涂覆的磁性纳米颗粒共价结合到每个微胶囊的壳中。 例如,(3-氨基丙基)三甲基硅烷涂覆的磁铁矿纳米颗粒可以在原位聚合期间引入脲 - 甲醛(UF)微胶囊的壳中。 在一个实施方案中,在种植期间施用包封肥料的微胶囊。 随后通过将磁场产生装置定位在微胶囊附近以产生足以通过有机硅烷涂覆的磁性纳米颗粒的磁刺激来破坏微胶囊壳的磁场,在适当的休眠期之后触发受控释放。 破裂的微胶囊壳释放肥料。
