Field card 01, start here

Which pesticide license do you actually need?

If you're running a lawn or landscape crew and about to start spraying, fertilizing, or treating turf for pay, here is the short version: you need a commercial applicator license and the Ornamental and Turf category, not the private track. Everyone else, pick your side of the fork below and we will name your category, your exams, and your state's steps in plain language, then walk you through calibrating your equipment correctly the first time.

Question 1 of 1, who are you spraying for

Track A

I spray my own or my employer's farmland

You are on the private applicator track. Restricted use pesticides on agricultural land you or your employer own or operate, no work for hire.

Core exam, in most states
No category exam in many states
Renewal by continuing education or retest

Show my private track Track B

I spray for customers who pay me

You are on the commercial applicator track. Lawn care, landscaping, structural pest control, aerial, right of way, anything applied for compensation on property you do not own or farm.

Core exam, always
Plus a category exam that matches the work
Company license and insurance rules may also apply

Show my commercial track

Quotable answer

Do I need a pesticide license to spray lawns for money?

Yes. Applying any pesticide for compensation on property you do not own or farm makes you a commercial applicator. That means passing the Core exam plus the Ornamental and Turf category exam through your state's certifying agency, then keeping the license current with continuing education or a retest.

Sec. 01

The 14 federal categories, on one card

40 CFR Part 171

Commercial applicators certify in one or more categories that match the work. States rename and split these, but every state list maps back to the federal set below. Two of them are endorsements you add on top of a category rather than stand-alone certifications.

Cat 01 Agricultural Plant Row crops, orchards, pasture, greenhouse food crops.

Cat 02 Agricultural Animal Livestock, poultry houses, animal-premises pests.

Cat 03 Forest Timber stands, site prep, forest nursery work.

Cat 04 Ornamental and Turf Lawn care, landscape beds, nurseries, sports turf. The lawn-crew category.

Cat 05 Seed Treatment Treating seed before planting or sale.

Cat 06 Aquatic Standing and flowing water, ponds, canals, irrigation.

Cat 07 Right of Way Roadsides, rail, utility corridors, industrial vegetation.

Cat 08 Structural and Industrial Buildings and their contents, general pest control.

Cat 09 Public Health Government vector control, mosquitoes, disease vectors.

Cat 10 Regulatory Government pest eradication and quarantine programs.

Cat 11 Demonstration and Research Instruction, field trials, extension demonstration.

Cat 12 Wood Destroying Organisms Termites and wood decay, often its own state license.

Cat 13 Aerial Endorsement, applications from aircraft.

Cat 14 Fumigation Endorsement, soil, structural, and commodity fumigants.

Not sure which line is yours? The Category and License Path Finder walks work type, for hire or not, and state, then names the category and the exams.

Sec. 02

Calibration and mix rate, worked out in front of you

Flagship tool

The math that fails people on the exam is the same math that burns a customer's lawn. Three steps, the formula shown, the arithmetic shown, and a coach that catches the four mistakes applicators actually make.

Step 1

Pick your equipment

Backpack or handheld sprayer, boom or broadcast sprayer, airblast or orchard sprayer, granular spreader, ULV or fogger. The rest of the workflow changes to match.

Step 2

Calibrate for real output

Measured area method or timed catch test. Output comes back as gallons per acre, gallons per 1,000 square feet, or pounds per acre for granular, with the formula and the numbers filled in.

Step 3

Do the label and mix math

Percent solution, parts per million, ounces of product per gallon, pounds of active ingredient per acre. Tank size in, product amount out.

Unit and decimal error coach, always running

Percent versus parts per million. A 0.5 percent mix is 5,000 ppm, not 500. We flag the swap.
Gallons per acre versus gallons per minute. Nozzle output is not application rate. We catch a rate typed into a flow field.
Active ingredient rate versus product rate. One pound of active ingredient is rarely one pound of product. We ask for the label percentage.
Misplaced decimal. Any result off by a factor of 10 from a normal range for that equipment gets held up before you mix.

Open the calibration workflow

The pesticide label is the legal controlling document. This tool is a study and planning aid, never a substitute for label directions.

Sec. 03

Your state's card

50 states plus DC

Certification is a state job, not a federal one. Each state card names the certifying agency, the exams, the license and exam fees, the renewal cycle, and how recertification works, with the date we last checked it.

We publish a state card only once every figure on it has a source and a date. Empty is better than wrong when the wrong number costs you a testing appointment: open the state matrix to see which states are live today.

Sec. 04

What the Core exam covers, and what renewal asks later

Core, part 1

Laws and labels

Federal and state pesticide law, restricted-use rules, recordkeeping, and reading a label well enough to answer questions written straight off one.

Core, part 2

Safety, PPE, environment

Personal protective equipment, exposure routes, first aid, spill response, drift, groundwater, pollinators, and endangered species buffers.

Core, part 3

Pest management and math

Integrated pest management principles, pest identification, resistance, plus the calibration and mix-rate arithmetic from Sec. 02.

Renewal is either continuing education hours or an exam retake, depending on your state and sometimes on your category. Miss the cycle and some states put you back through the exams. Your state card carries the cycle length and the hour count once it is verified.
