Which of the following is NOT a responsibility of the DPR?

The responsibility of training county program administrators typically falls under the purview of the counties themselves rather than the Department of Pesticide Regulation (DPR). The DPR focuses on overseeing and ensuring the proper implementation of pesticide regulations at the state level. While they may provide resources and support for effective program administration, the actual training and professional development of county program staff are generally implemented locally by the respective county programs.

Options involving assistance in planning or developing county programs, reporting to the Legislature, and developing county priorities imply that the DPR plays a significant role in shaping regulations, providing oversight, and collaboratively setting agricultural priorities, which aligns with their main goals of regulatory compliance and safe pesticide use.
