Adjuvants

Adjuvants are used to support or modify an agrochemical’s actions or characteristics. In pesticides, they are often used for wetting, spreading, emulsifying, deflocculating, deposit-building or water-modifying.

For maximum effectiveness, adjuvants must be matched with the herbicide, the crop species, the weed species and the prevailing environment.

Dow’s ECOSURF™ and TRITON™ Surfactants offer versatile wetting properties and exceptional wetting performance, even at low concentrations. They also provide excellent surface-tension reduction and rapid reaction to enable desired suspendibility, bloom and resuspendibility in dry, flowable formulations.
