Adjuvants can modify a broad range of properties in a tank mix solution, such as droplet size, pH of the solution, increased plant uptake, and many others. In many ways, it comes down to assisting the active ingredient to move to, on, or into the plant to do its job. Spray adjuvants enhance the effectiveness of herbicides, insecticides, fungicides, and other agents used in agricultural, turf, and professional vegetation management. Without the addition of the right adjuvant, those active ingredients would not reach their full potential in many situations.
Spray additives can be grouped into two broad categories: activator and special purpose modifiers. Activator adjuvants include surfactants, wetting agents, stickers-spreaders, and penetrants; special purpose or utility modifiers such as emulsifiers, dispersants, stabilizing agents, coupling agents, co-solvents, compatibility agents, buffering agents, antifoam agents, drift control agents, and nutritional additives.
