Which recommended practice will minimize pesticide storage problems?

Minimizing pesticide storage problems is critical for safety and compliance with regulation. The recommendation to store metal pesticide containers on higher shelves to prevent rusting reflects an understanding of preventing deterioration of pesticide containers. Metal containers can be susceptible to rust, particularly if they come into contact with moisture. By keeping them elevated, exposure to damp flooring or spills can be reduced, thus prolonging the lifespan of the containers and maintaining the integrity of the pesticides stored within them. This practice not only helps to safeguard the chemical stability of the pesticides but also minimizes potential risks associated with leaking or broken containers, contributing to a safer storage environment.

The other options would not effectively address storage challenges. For example, purchasing based on previous usage may lead to either excess inventory or shortages, depending on fluctuations in use. Buying more than needed might lead to overstocking and potential disposal issues if products expire. Lastly, storing all pesticides together without regard to type can create risks of contamination or improper access to chemicals, potentially resulting in dangerous combinations or exposure.
