Choosing Spray Adjuvants

Choosing the most suitable adjuvant for each chemical application can be a confusing process, given the vast array of wetters, oils, combinations and other adjuvants available on the market.  Consideration must be given to the type of chemical, the spray target, the crop, pasture or fallow situation, plus the environmental conditions at the time.

GRDC has published a reference manual titled “Adjuvants – oils, surfactants & other additives for farm chemicals” which provides extensive information on the different types of adjuvants and where to use them.

The table below shows some of the most common adjuvants available, plus their uses. The complete manual can be accessed via the link below:
