Pesticides must be stored in what conditions?

Pesticides must be stored in cool and dry conditions to maintain their effectiveness and stability. Storing them in a cool environment helps to prevent degradation of the active ingredients that can occur at higher temperatures, which may diminish their potency and increase the likelihood of ineffectiveness when applied. A dry environment is crucial as moisture can lead to clumping, degradation, or chemical reactions that could render the pesticides unsafe or less effective. Proper storage conditions also help to prevent the growth of mold and bacteria that can occur in humid environments, further preserving the integrity of the pesticides.

While a warm and dry condition may seem reasonable, warmth can compromise the stability of many pesticides. Hot and humid or cold and wet conditions are detrimental because they can promote degradation or physical changes in the product, leading to decreased efficacy and potential safety hazards.
