Applicator licenses and operators
You need a pesticide applicator's license to apply pesticides for others, and you are responsible for what your operators and employees apply. Operators are licensed, work under direct supervision within 100 miles of the applicator, and use only the pesticides the applicator is qualified for.
What every application record holds
Record the certified applicator's name and certification number and any operator who applied it, the date with start and end times, the owner's or lessee's name and address and the specific site, the equipment, each product's company name, trade name and EPA number, the rate, the area treated or type of structural treatment, the pests, and the weather if applicable. Each product in a tank mix gets its own full entry.
Within 24 hours, kept two years
Write the record within 24 hours. Keep records two years and open to the Department during business hours; on a written request, send them within 14 calendar days, and document any period with no applications. Records held by the Department can be public.
Restricted use pesticides
Before applying a restricted use pesticide, tell the owner, lessee or manager about all precautions and restrictions, and give them a copy of the label if they ask.
From field notes to a finished Montana record
Note when you started and finished, the equipment, each product with its maker, EPA number and rate, and the area treated. ReportDraft puts the times, equipment, certification number and any operator in the header and lays out each product with the company and trade name the rule asks for.
Common mistakes
- No end time, only a start time.
- A trade name without the company name.
- No equipment listed.
- One line for a tank mix instead of one entry per product.
- Writing the record days later instead of within 24 hours.
