In what order should you fill the tank when mixing pesticides?

The correct method for filling the tank when mixing pesticides involves filling the tank 1/5 to 1/2 full with the carrier (usually water) before adding the other products. This approach is important for several reasons.

First, starting with a partially filled tank ensures that there is adequate volume to properly dissolve and distribute the pesticides. When the carrier is added first, it helps to create a uniform solution that can effectively mix with the pesticides added afterward, minimizing the risk of clumping or ineffective mixing.

Secondly, many pesticide formulations, particularly those that are suspensions, require a certain amount of carrier to be present in order to dissolve adequately and act correctly when applied. If dry products or suspensions are added to an empty tank or to water that is too low, they may not disperse well, leading to inconsistent application and potential crop damage.

Moreover, following a specific order can also prevent adverse chemical reactions between various products that may occur if they are mixed incorrectly. By carefully managing the order and the amount of carrier used initially, the tank mix becomes more stable and effective for application.

This thorough understanding of best practices is essential for any pesticide supervisor, as it directly affects both application efficacy and regulatory compliance.
