Missouri Guidelines for Pesticide Recertification Programs

  2. Section 281.100 and 2 CSR 70-25.050 (2) of the Missouri Pesticide Use Act and regulations authorizes the Missouri Department of Agricultures Bureau of Pesticide Control, to establish minimum criteria for recertifying Missouri certified Commercial and Noncommercial Pesticide Applicators and Public Operators.

    Each recertification training course must be approved in advance by the Bureau of Pesticide Control. No course will be given post approval. Individuals attending courses prior to approval will NOT be recertified.

    The Bureau cannot approve a course for a period of time when staff are not available to monitor the program. Please submit programs as early as possible. Programs will be reviewed in order received.

    For a course to be considered for recertification credit in Missouri, the program must comply with the following:

    • The course must be open to the public without discrimination.
    • A final, written course agenda must be received by the Bureau of Pesticide Control at least 45 days (90 preferred) in advance of the proposed program. The agenda must include:
    1. Program curriculum with a detailed description of each topic.
    2. Times allotted for each section.
    3. List of proposed speakers and qualifications.
    4. Location, date, and time of the program.
    5. Applicator participation method.
    6. Estimated number of Missouri applicators expected to attend the program.
    7. Attendance verification procedure.

    Failure to supply the required information, will be grounds for rejection.

    • Copies of the training materials (audio, visual, and printed) should be available for Bureau review upon request.

    The Bureau will attempt to work with any group to improve courses which do not qualify for recertification credit. It is the program sponsor’s responsibility to acquire the needed materials and/or speakers for the program.

    Bureau of Pesticide Control personnel will monitor all in-state recertification programs. Time and space must be approved for Bureau personnel to distribute and collect recertification forms at the end of the program. All fees charged for the recertification program shall be waived for Bureau of Pesticide Control personnel monitoring the program. Bureau personnel shall be provided copies of all materials distributed to the program attendees.

    The program sponsor shall provide a sign-in sheet for attendees desiring Missouri recertification credit. This is in addition to the program registration procedure. The sign-in sheet must contain: the applicator’s name, business name, business address, and Missouri pesticide license number. The sign-in sheets will be presented to the Bureau personnel at the close of registration or when requested by the Bureau personnel.

    Final approval of a recertification program depends upon actual program content. If, in the opinion of the personnel monitoring the program, the approved curriculum was not followed, the course content was altered so that it no longer met the minimum standards, or if the coverage of the topics was inadequate, they may leave the program and recertification would not be granted to those attending the program.

    These guidelines may change without notice. However, once a program is approved using a particular set of guidelines, the sponsor will not be required to change the content of the program.

  4. The following topics are considered to be a MINIMUM needed for approval of a program for recertification credit in Missouri.

    These topics are based on requirements found in 40 CFR 171.4 and the National Training Priorities required by the U.S. Environmental Protection Agency. This material must be easily recognizable in both the written agenda and the actual program.

    The suggested times set for each topic are designed for the entire program to be covered in a single day allowing for adequate breaks. For ease of monitoring and verifying attendance, it is recommended the entire recertification program be offered in a single day.

  6. The information provided should be directed toward reviewing basic information in each topic area and updating each area by including new information that has been developed in the last three to five years.
