When are adjuvants added to pesticide mixtures?

• A. Adjuvants are added afterwards by applicators.
• B. Adjuvants are added during formulation by manufacturers.
• C. Adjuvants are added before mixing by the operator.
• D. Adjuvants are always added at packaging.

Answer: (A)

Adjuvants are added in the field when preparing the spray mixture, by the applicator during the tank-mixing stage. This timing lets the operator choose and adjust the adjuvant based on the site, surface, water quality, and target pest, and ensures the adjuvant is present in the final spray solution. Some products may include adjuvants in their formulation, but the typical practice is for the applicator to add adjuvants at mixing time, not during manufacturing, packaging, or before mixing.
