After filling a tank one-fifth to one-half full with carrier, what is the usual order for tank mixing the remaining products?

The typical order of tank mixing is critical for ensuring the effectiveness and stability of the pesticide formulations. The correct sequence begins with adding a compatibility agent, which helps prevent any potential reactions that could occur between different formulations. Following that, suspension products are added next. This is because suspensions can settle and require thorough mixing to ensure the active ingredients are evenly distributed in the tank.

After the suspension products, solution products are introduced. Adding these next helps maintain the stability of the mixtures, as they dissolve easily in the carrier and can interact properly with the previously added products. Then, surfactants are included, which assist in enhancing the effectiveness of the application by improving the spread and adherence of the mixture onto the target surfaces. Lastly, emulsion products are introduced, as they require careful mixing and can be sensitive to the order of addition due to their composition.

This methodical approach helps ensure that all substances integrate properly without causing clumping, sedimentation, or separation, which can reduce the efficacy of pest control measures.
