Pesticide Applicator Licensing

Licensing rules for pesticide applicators are set by states and tribes, within federal standards, and they vary a great deal. This guide gives the big picture and tells you who to ask.

What does applicator licensing mean?

Applicator licensing or certification is a way for states to make sure that people who apply certain pesticides understand safe handling, labels and laws. The exact word used, license, certificate or permit, differs by state.

Requirements may depend on the type of product, the type of work, whether you apply for hire and whether you are applying on your own land.

The system can feel confusing because different people use the same words for different things. When you call your state agency, describe what you do and what you apply, then ask which category covers you instead of asking only whether you need a license.

• Terms differ by state: license, certificate or permit.
• Category depends on the product and the work.
• Ask in writing if you need a clear answer.

How is it different on my own farm?

Many states treat private applicators, meaning people applying on their own or their employer's land to produce an agricultural commodity, differently from commercial applicators who apply for hire. Private certification is often tied to restricted-use products.

Do not assume that you are exempt from licensing rules. Ask your state agency to explain the category you belong to.

Family members who help with spraying are an important group. Ask your state how it treats helpers, and whether they must be certified or may work under supervision.

• Private applicators often work on their own or their employer's land.
• Commercial applicators work for hire.
• Rules for each differ by state.

What about commercial and custom applicators?

People who apply pesticides for hire usually need a commercial license and may need business registration, insurance or categories that match their work. Requirements vary, so confirm with the state.

If you hire someone, ask for evidence of their license and ask for records of what was applied on your land.

Ask each applicant you hire about experience with your crop, your buffers and sensitive neighbors. A license shows that a person met the state requirement, but conversation shows how they work.

• Ask for the applicator's license information.
• Confirm the license categories fit the work.
• Ask for application records after each job.
• Review the label together before the job.

How do I get started?

Contact your state lead agency, which is generally the department of agriculture. Ask what type of license applies, what training is needed and how exams are scheduled. Your cooperative extension office can often explain study options and run training sessions.

Plan ahead, since exams and sessions may be offered only at certain times of year.

Allow time for the process. Some states have waiting periods, limited exam sessions or paperwork that takes weeks. Starting in winter may mean you are ready by spring.

• Call the state lead agency.
• Ask which license applies.
• Ask about training and exam dates.

What are the typical steps?

The pattern in many states includes study, an exam, payment of any required fees and proof of any financial responsibility for commercial work. This site does not give fees or dates. Your state agency will give the current information.

Keep proof of your license accessible when you work, and know your renewal schedule.

Keep a file with your license, receipts, renewal notices and training records, so you can show them if an inspector asks.

What are my duties once licensed?

Licensed applicators must follow the label, keep records as required, use protective equipment and take care to avoid harm to people and the environment. They may also be responsible for supervising other people.

Training does not end with the exam. Continue to read labels and attend updates when offered.

Licensing can bring inspections. Keep records, labels and safety data sheets organized so that an inspector can see your practices clearly, and treat inspectors as a source of advice.

What if someone is applying without a license?

If you are concerned about unlicensed application on or near your land, contact your state agency. Do not confront anyone in a way that could create a dangerous situation. Keep notes of what you saw and when.

If someone is exposed, call 911 in an emergency.

People sometimes feel awkward raising these questions. Remember that agencies exist to help applicators comply, and extension educators are used to explaining the system without judgment.
