Abstract
Viscoelastic fluid compositions are provided that have improved properties for suspending particulate active ingredients. Methods for forming the compositions are also provided. The compositions preferably have a non-Newtonian behavior, so that the viscosity of the composition at low shear rates is suitable for keeping solid particles in the form of a stable suspension while also providing a reduced viscosity at higher shear rates (such as a substantially reduced or minimized viscosity) to allow for pumping, tank mixing, and/or distribution of the composition, for instance by spraying.
