    Abstract

    Oil dispersions (OD) of spray drift mitigation agents offer ease of incorporation of the agent into the tank mix. An oil dispersion of guar gum has been developed that not only achieves even dispersion of guar into the spray tank but also exhibits good physical stability. The influence of dispersing agents and emulsifiers on spray characteristics, rheology, and physical stability was examined.
