What is one reason why diluted pesticides can be problematic during storage?

Diluted pesticides can be problematic during storage primarily because they can freeze and damage containers. When pesticides are mixed with water or other solvents, the resulting solution may have a lower freezing point than the pure pesticide formulation. In cold temperatures, this can lead to the dilution freezing within the container, which can create pressure and eventually cause the container to crack or burst. This not only results in the loss of the product but also poses safety hazards from potential spills or leaks.

While other factors, such as evaporation, attraction of pests, and chemical reactions, could relate to pesticide storage, they do not specifically highlight the unique risks associated with diluted formulations. Evaporation might occur with concentrated pesticides more so than with diluted ones, and attracting pests is less of a concern when pesticides are stored properly. Chemical reactions are typically more problematic within the concentrated products, rather than the diluted forms during storage. Thus, the risk of freezing and damaging containers is a key concern that highlights the importance of considering storage conditions for diluted pesticides.
