  A granular agrochemical composition is disclosed including a granular core material having a water soluble portion with a first coating layer applied on the surface of the core material and a second coating layer applied on the surface of the first coating layer. The first coating layer includes a wax composition having a biologically active ingredient incorporated therein and the second coating layer includes a polymeric composition.; The granular agrochemical composition exhibits a controlled rate of release of the biologically active ingredient therefrom over a period greater than about 30 days from the date of initial exposure of the granular composition to moisture whereby essentially all of the biologically active ingredient incorporated in the wax material of the first coating layer is released from the granular composition before the water soluble portion of the granular core material is released from the granular composition.

  本发明公开了一种颗粒状农用化学品组合物，包括一种颗粒状芯材，芯材具有水溶性部分，芯材表面涂有第一涂布层，第一涂布层表面涂有第二涂布层。颗粒状农用化学品组合物显示出生物活性成分从颗粒状组合物中释放的可控速率，从颗粒状组合物最初暴露于湿气之日起超过约 30 天的时间内，颗粒状组合物中的生物活性成分基本上全部从第一涂布层的蜡材料中释放出来，然后颗粒状芯材的水溶性部分才从颗粒状组合物中释放出来。

  A controlled release product is provided having a suppressed initial release period and a predetermined longevity. The product includes a particulate water soluble core material and a semi-permeable coating layer applied on the core material for controlling the release rate of the core material. The semi-permeable coating layer is formulated in accordance with the following equation to provide a release rate wherein initial release of core material from the product is suppressed so that less than about 15 weight percent of core material is released from the product within a 24 hour period after application of the product and wherein longevity of release, at ambient temperature, between the time of application and the time at which at least about 75 weight percent of the core material is released from the product is 60 days or less: 1 WVTR = φ · δ π ⁢ ⁢ d 2 wherein: (i) WVTR is the water vapor transmission rate of the semi-permeable coating expressed in grams·&mgr;m/meters 2 ·day; (ii) &phgr; is the water diffusion rate (water flux) through the semi-permeable coating expressed in grams/day; (iii) &dgr; is the thickness of the coating layer expressed in &mgr;m; and (iv) d is the average diameter of the particulate core material expressed in meters.

  一种控释产品具有被抑制的初始释放期和预定的持久性。该产品包括颗粒状水溶性芯材和涂在芯材上用于控制芯材释放率的半透涂层。半透性涂层层按下式配制，以提供一种释放率，其中芯材从产品中的初始释放被抑制，从而在施用产品后的 24 小时内从产品中释放的芯材少于约 15 重量百分比，并且在环境温度下，从施用时间到至少约 75 重量百分比的芯材从产品中释放的时间之间的释放寿命为 60 天或更短： 1 WVTR = φ &CenterDot； δ π &it； &it； d 2 其中 (i) WVTR 是半透涂料的水蒸气透过率，以克-&mgr;米/米表示 2 -天； (ii) &phgr；是通过半透涂层的水扩散率（水通量），单位为克/天； (iii) &dgr；是涂层的厚度，单位为米 (iv) d 是颗粒核心材料的平均直径，以米为单位。
