The Role of Orchex 796 in Pesticide Applications


A renewed interest in improving the application of chemical pesticides has prompted additional application research on utilizing spray adjuvants for enhancing ground or aerial pesticide applications. This renewed interest is producing additional findings on the role of Orchex® 796 in pesticide applications, as well as research leads for improving pesticide formulations. This paper reviews these additional findings, primarily from published research.

While Orchex® 796 was initially developed for tree pests, its general surface chemistry and other lipid-like properties provide improved spreadability and coverage on biological surfaces. Further, both plant and insect surfaces are modified in a beneficial manner for the application of many pesticides. In addition to providing a temporary modification of the target surface, other properties improve rainfastness. These features provide a greater benefit in ultra low volume application including nonaqueous application, but still retain benefits when applied with even high rates of water, such as in chemigation. Specific crop and pest examples are presented from both temperate and tropical agriculture. These examples illustrate how Orchex 796 properties can provide a multiple role in the formulation or application of pesticides.
