After filling a tank 1/5 to 1/2 full with carrier, what is the usual order for tank mixing the remaining products?

• A. add suspension products, add emulsion products, add solution products, add surfactants (if needed), add compatibility agent (if needed).
• B. Add compatibility agent (if needed), add suspension products, add solution products, add surfactants (if needed), add emulsion products.
• C. Add surfactants (if needed), add suspension products, add emulsion products, add solution products, add compatibility agent (if needed).
• D. Add water first, then add products in any order

Answer: (B)

The key idea is that the mixing sequence is chosen to prevent incompatibilities and ensure even dispersion as you build the final tank mix. Start with a compatibility agent (if the label says you should) so any potential chemical interactions are addressed before introducing other products. Then add suspension products, which contain solid particles that need thorough wetting and dispersion. Next come solution products, which are already dissolved and can mix with the dispersed solids, but you want them after the suspensions are underway to avoid issues with precipitation. If needed, add surfactants to improve wetting and stability once the core mix is formed. Finally, add emulsifiable concentrates last, because they are oily and can destabilize a mixture or form unwanted emulsions if added too early. This order helps keep the mixture uniform and stable throughout agitation. Always follow the product labels for any specific sequence or compatibility notes.
