What is the recommended practice for adding components to a tank mix in the correct order?

• A. Add all components at once without sequence.
• B. Add water last.
• C. Add adjuvants first.
• D. Follow label order; typically water first, then flowables, then emulsifiable concentrates, then soluble liquids, then adjuvants; ensure compatibility with a jar test.

Answer: (D)

The main idea is that tank mixes must be built in a specific order to ensure all components dissolve, disperse, and mix evenly without causing incompatibilities. Follow the product label for the order, which typically starts with water to create a uniform base, then adds flowables, then emulsifiable concentrates, then soluble liquids, and finally adjuvants. This sequence helps prevent solids from clumping or settling, promotes proper wetting and dispersion, and reduces the chance of premature emulsions or other interactions that can cause separation or poor coverage. After assembling the mix in that order, run a jar test to check compatibility before using the spray tank—look for precipitation, separation, gel formation, or excessive foaming. If the jar test shows issues, do not proceed with the mix as-is; adjust the order or omit incompatible components per label instructions.
