Which entity regulates the control of turf and ornamental pests in Illinois?

The Illinois Department of Agriculture is the entity responsible for regulating turf and ornamental pests in Illinois. This department oversees the management and control of agricultural pests, which includes a wide range of issues relating to plant health in both agricultural and urban environments. It provides guidelines for pest management, including the use of pesticides, and ensures that these practices are safe and environmentally sound.

The Illinois Department of Natural Resources primarily focuses on wildlife and natural resource management, while the Illinois Environmental Protection Agency deals with environmental issues, including water quality and pollution control. The Illinois Department of Commerce is more focused on economic development and business support rather than pest control or agricultural issues. Therefore, the role of regulation concerning turf and ornamental pests falls squarely within the purview of the Illinois Department of Agriculture.
