Specific dearomatized hydrocarbon fractions with boiling ranges between 220 and 310°C can significantly increase the performance of active ingredients in certain herbicides, fungicides and insecticides when they are incorporated, in combination with surfactants, in the formulations (co-adjuvants) or used as adjuvants in tank mixes.

With the help of these tailor-made fluids, the biological activity of the active ingredients can be improved or modified. Efficacy is significantly increased and other important physico-chemical characteristics; such as, application properties, volatility versus penetration and mode of action, can be modified. The adjustment of these parameters adds formulation flexibility, increases activity which results in cost savings (less pesticide is required per hectare) and environmental benefits (reduction of undesirable residues).

To demonstrate these benefits, two specific pesticides were selected: an insecticide (new generation of pyrethroid) and an herbicide (diphenyl ether family). These active ingredients were then formulated using these tailor-made dearomatized hydrocarbon fluids, other coformulants and specific surfactants and their performance assessed in green house and field trials. Comparisons with other established adjuvants are included where available.
