In a tank mix, what should be added immediately after Flowables?

• A. ECs
• B. Water Solubles (WS)
• C. WPs
• D. Water

Answer: (B)

Tank-mix order matters because different product types behave differently in water. Flowables are suspensions of fine solid particles; they need careful stirring to stay evenly dispersed. Once those solids are in, adding water-soluble products next lets them dissolve quickly and uniformly in the already-agitated mixture. Water-soluble formulations are designed to dissolve readily, so introducing them after the Flowables helps prevent incomplete dissolution or precipitation and keeps the overall mix consistent for application. Following this sequence promotes compatibility and a smoother, more uniform spray. Always check the label for the exact mixing order, but in many mixes the water-soluble products are added immediately after the Flowables.
