Annual Registration and Renewal

Mandatory Registration

Every pesticide distributed, sold, or transported within Montana must be registered with the state's Department of Agriculture. This requirement extends to intrastate commerce and transportation. All pesticide registrations expire on December 31 of the year they are issued, necessitating annual renewals.

Application Details

The registration process requires detailed information:

Imported Pesticides

Pesticides registered under federal law must also be registered in Montana. The state may impose additional restrictions on their sale, use, and application.

Fees and Financial Requirements

Annual Registration Fee

Each pesticide registration incurs an annual fee ranging from $138 to $233, adjustable by the department to ensure sufficient funding for regulatory activities. This fee applies to:

Special Needs Fee

An additional fee of $8 to $11 is assessed per registration to fund the Montana State University Extension Service's pesticide education program. This program focuses on the certification and training of farm applicators.

Compliance and Enforcement

Formula and Standards Submission

The department may require submission of the complete pesticide formula and certified analytical standards. Pesticides must meet specific composition and labeling standards to be registered.

Corrective Actions

If a pesticide or its labeling does not comply with regulations, the department will notify the applicant to make necessary corrections. Failure to comply may result in registration denial, suspension, or cancellation. Registrants have the right to pursue administrative remedies under the Montana Administrative Procedure Act.

Exemptions and Special Cases

Registration is not required for pesticides shipped between plants within the state by the same entity.

Review and Approval Process

Interagency Collaboration

The departments of agriculture, public health and human services, and fish, wildlife, and parks jointly review applications for experimental-use permits or special local needs registrations. They follow federal standards and must approve or disapprove applications within 10 days.

Conflict Resolution

Disagreements between departments on registration are resolved through interagency conferences or joint administrative hearings. If unresolved, an advisory council may be appointed to make final recommendations.

Federal Cancellations

Federal Cancellation Compliance

Pesticides canceled under federal law are similarly canceled in Montana. The state adheres to federal guidelines for the final date of sale or use and may provide assistance for proper disposal or relabeling of remaining stocks. Extensions for use may be granted under specific conditions, not exceeding six years from the termination date.
