In the pesticide tank mixing order, which step comes immediately after starting agitation?

• A. Add compatibility agent (if needed)
• B. Add emulsion products
• C. Fill tank 1/5 to 1/2 full with carrier
• D. Add surfactants or other adjuvants

Answer: (A)

Starting agitation is the moment to introduce a compatibility agent if you’re using one. The goal is to get this additive dispersed evenly right from the start so it can help the rest of the tank mix stay uniform and prevent incompatibilities like precipitation or separation as other products are added. If you wait to add it later, it may not distribute as effectively, and you can end up with uneven mixing or clumping.

The other steps are typically handled at different points in the sequence. Filling the tank with carrier happens before agitation so there’s enough liquid to circulate, and emulsion products or surfactants/adjuvants are usually added after the system is already moving and the compatibility issues have been addressed, ensuring a stable, well-mixed solution.
