This Small Business Innovation Research Phase I project examines the feasibility of novel controlled release methods of herbicide delivery that will significantly limit pollution due to agricultural runoff. The research utilizes natural layered minerals that are able to sequester and later release herbicides gradually into soils or foliage; and will examine the feasibility of developing time-delayed release agents that will prevent dissolution and runoff of herbicides during critical heavy rainfall events. Further, the research effort will examine the feasibility to utilize an intensified process to prepare the proposed composites, a process which is carried out at room temperature, involves only a single step, produces no by-products, and renders the proposed product highly cost-effective for its end customers. The broader impacts of this research will be development of cost-effective products that mitigate the environmental impact of agricultural runoff (one of our nations most significant sources of pollution), and will mitigate the concomitant collateral damage (both environmental and economic) to our nations fisheries. Customers, such as nurseries, greenhouse growers and farmers, will derive several benefits from products resulting from this research: a time-delayed, controlled-release product may potentially eliminate the need for multiple applications of herbicides, will minimize exposure of workers to harmful herbicides, may potentially limit or eliminate herbicidal runoff to adjacent watersheds, and may provide significant cost-savings.

该小企业创新研究第一阶段项目研究了新型除草剂控释方法的可行性，该方法将显着限制农业径流造成的污染。 该研究利用天然层状矿物质，能够将除草剂隔离并随后逐渐释放到土壤或树叶中；并将研究开发延时释放剂的可行性，以防止除草剂在关键的强降雨事件期间溶解和流失。 此外，研究工作将检验利用强化工艺来制备所提出的复合材料的可行性，该工艺在室温下进行，仅涉及一个步骤，不产生副产物，并使所提出​​的产品成本高昂。对最终客户有效。 这项研究的更广泛影响将是开发具有成本效益的产品，减轻农业径流（我们国家最重要的污染源之一）对环境的影响，并将减轻随之而来的对我们国家的附带损害（环境和经济）渔业。苗圃、温室种植者和农民等客户将从这项研究的产品中获得多种好处：延时、控释产品可能会消除多次使用除草剂的需要，并最大限度地减少工人接触有害除草剂的机会，可能会限制或消除邻近流域的除草剂径流，并可能显着节省成本。
