Welcome to the Division of Plant Health
The Ohio Department of Agriculture's Division of Plant Health houses the Grain Warehouse, Feed & Seed, Pesticide & Fertilizer Regulation, and Plant Pest Control sections, which are responsible for many consumer- and farmer-protections regulations. Staff members' duties include registering pesticides, licensing pesticide applicators, investigating pesticide use complaints, verifying label statements on feed and fertilizers, monitoring the financial stability of grain elevators, testing germination of packaged seeds, inspecting honey bee colonies, regulating plant nursery stock, and working with USDA-APHIS and the U.S. Forest Service to control invasive pest species. Our goal is to hold businesses which produce, process, and distribute plant-based agricultural products to high standards of integrity and safety.
