    Middle distillates, such as kerosene or diesel, are often used as carriers and adjuvants in phenoxy herbicides for turf, right-of-way sprays, and other applications. In recent years, however, the use of middle distillates in these applications has come under pressure due to toxicity concerns. As an alternative to these middle distillates, it has been proposed that dearomatized fluids could be used in these applications, potentially giving better performance. The lower volatility and lower phytotoxicity of the dearomatized fluid may promote enhanced uptake of the herbicide, resulting in improved performance. To test this proposal, a study was conducted comparing the use of dearomatized hydrocarbon fluids (such as Exxsol® D110 fluid) as both solvent and adjuvant to the use of kerosene/diesel as the solvent/adjuvant combination in right-of-way sprays. The herbicide product 2,4-D Ester was applied to three vegetation types at two rates, the vegetation types including kochia, marestail, and horsetail. Results from the study showed that the 2,4-D Ester gave good control of marestail and equisetum, but only poor control of kochia. In all cases, the dearomatized fluid performed as well as kerosene/diesel, demonstrating that dearomatized fluids can be used as a safe replacement for middle distillates in these applications.
