When there's a conflict between state and federal regulations concerning pesticides, which regulation takes precedence?

In instances where there is a conflict between state and federal regulations regarding pesticides, the most restrictive regulation takes precedence. This means that if state laws impose stricter requirements or limitations than federal laws, those state regulations will apply. The logic behind this approach is to ensure a higher level of safety and protection for public health and the environment. State regulations often reflect the specific needs and circumstances of that state, and they may incorporate additional safeguards that are not present in federal standards. Conversely, if federal regulations are more stringent, then those would take precedent over the less restrictive state laws. This principle is vital for ensuring that all pesticide applications are aligned with the highest safety standards available.
