An important aspect of temperature control during pesticide mixing is that pesticides should be kept dry. Maintaining the proper moisture level helps ensure that the pesticides maintain their effectiveness and stability. When pesticides are wet or mixed with excessive moisture, they can degrade or lose their potency, leading to reduced efficacy when applied. Furthermore, certain pesticides may have specific requirements for mixing, including the need to avoid water, as it can cause chemical reactions that produce harmful or ineffective mixtures. Keeping pesticides dry prevents these issues and ensures safe handling, as wet products may also be more hazardous during the mixing process.

The other options focus on conditions that could negatively impact pesticide effectiveness or safety. For instance, exposing pesticides to sunlight can lead to photodegradation, reducing their effectiveness. Mixing above 100 degrees F may also be detrimental as high temperatures can alter the chemical composition of pesticides, affecting their performance and increasing safety risks. Using plastic containers is typically a matter of compatibility and safety rather than temperature control itself; some materials can react with pesticides if not chosen appropriately.
