Record keeping in Michigan
Retention: 1–3 years. Michigan commercial applicators must keep application records — at least one year for general applications and three years for some categories under MDARD's pesticide regulations, with the federal two-year baseline applying to restricted-use products. Recording every application the same way, and keeping it three years, satisfies all of them at once.
Licensing: Commercial Applicator Certification, administered by Michigan Department of Agriculture & Rural Development (MDARD).
Notification & posting rules
Michigan maintains a registry-based advance notification program for sensitive individuals, and commercial ornamental/turf applications carry posting requirements at the time of application.
