This invention is based on unexpected effect of at least one thickener to maintain suspension or dispersion of solid particles in an oil medium. Such effect of thickener enables significant higher weight ratio of solid particles in such suspension composition as compared to previously known compositions. As a consequence, the suspension compositions provided herein enable more active ingredient in the solid particle to be present in a fixed volume or weight of such composition as compared to previously known compositions. One advantage of the suspension composition provided herein can be for aerial spraying of active ingredient such as herbicides, insecticides, or other growth regulating compounds.
