Mich. Comp. Laws § 324.8309: Refusing, canceling, or suspending registration; circumstances.

Sec. 8309.

The director may refuse to register or may cancel or suspend registration of a pesticide if any of the following circumstances exist:

The pesticide does not meet its EPA registration and labeling claims.

The pesticide labeling and other material required to be submitted does not comply with this part or the rules promulgated under this part.

The pesticide is in violation of this part.

Based on substantial scientific evidence, the director determines that the use of the pesticide is likely to cause an unreasonable adverse effect on the environment, which cannot be controlled by designating the pesticide as a restricted use pesticide, by limiting the uses for which a pesticide may be used or registered, or by other changes to the registration or pesticide label.
