Pesticide Product Registration
The Michigan Department of Agriculture and Rural Development registers pesticides that are sold in the state of Michigan. Michigan law requires that all products which make a pesticidal claim must be registered with the state. The state defines a pesticide as "a substance or mixture of substances intended for preventing, destroying, repelling or mitigating pests or intended as a plant regulator, defoliant, or desiccant." A pest is defined as "an insect, rodent, nematode, fungus, weed and other forms of terrestrial or aquatic plant or animal life or virus, bacteria, or other microorganism, except viruses, fungi, bacteria, nematodes or other microorganisms in or on living animals."
