What is the usual order for tank mixing pesticides?

The correct order for tank mixing pesticides emphasizes the importance of maintaining compatibility and achieving a homogeneous mixture. By filling the tank one-fifth to one-half full with the carrier first, you ensure that there is enough liquid to dissolve and suspend the various products. Adding a compatibility agent, if needed, at this early stage helps prevent issues that can arise from incompatible products mixing together.

Following this, adding suspension products before emulsion products is critical. Suspension products are typically solid particles that need to be adequately dispersed in the liquid carrier, so they should be added next. Emulsion products usually contain oil and water phases that require proper mixing to be effective, so they follow suspension products in the order. Then, solution products, which are already dissolved in the carrier, can be added last to avoid any potential reactions or settling that might occur with earlier additions.

The inclusion of surfactants at the end is also strategic because they aid in enhancing the efficacy of the spray mix, improving wetting and adherence to surfaces. This sequence helps ensure each product is properly integrated, leading to the best performance of the pesticide mix.
