    • The present invention relates to an oil-in-water emulsion, comprising oily globules that include at least one agriculturally active ingredient, in which the oily globules of the emulsion and are coated with a polymeric adsorption layer. The polymeric adsorption layer coating the oily globules includes (1) at least one polymeric surface-active agent having an HLB values in the range of about 16 to about 18, and (2) at least one ionic surface-active agent. The oily globules of the emulsion have mean particle diameter of less than about 800 nanometers, are resistant to Ostwald ripening and are well suited for the treatment of plants. Agriculturally active ingredients that can be used with the emulsion include, pesticides, herbicides, fungicides, mitocides, bactericides and the like. The invention further includes methods of using the inventive oil-in-water emulsions to treat plants and on surfaces adjacent to plants, plant pests or other pests.
    • 本发明涉及一种水包油乳液,其包含含有至少一种农业活性成分的油性小球,其中乳液的油状球体涂覆有聚合物吸附层。 涂覆油性球的聚合物吸附层包括(1)至少一种HLB值在约16至约18范围内的聚合物表面活性剂,和(2)至少一种离子表面活性剂。 乳状液的油状球体的平均粒径小于约800纳米,对奥斯特瓦尔德熟化有抗性,非常适合于植物的处理。 可与乳液一起使用的农业活性成分包括杀虫剂,除草剂,杀真菌剂,杀线虫剂,杀菌剂等。 本发明还包括使用本发明的水包油乳液来处理植物和在植物,植物害虫或其它害虫附近的表面上的方法。
