Alabama pesticide license for lawn care and landscaping

Checked October 2026

To spray herbicide or insecticide on lawns for pay in Alabama, one person passes the Ornamental and Turf Pest Control Supervisor (OTPS) exam, then holds a $45 commercial applicator permit, and the business buys a $175 Horticulture Professional Services license that runs October 1 to September 30. The exam costs $75 on paper in Montgomery or $125 at a computer site. The department's insurance rule names $150,000 for structural work only, not lawn work.

Alabama's insurance rule for professional pest work lists three structural categories, then stops. Ornamental and turf is not one of them. A lawn company spraying under Ornamental and Turf Pest Control has no dollar minimum to meet in the rule text the Alabama Department of Agriculture and Industries (ADAI) posts, the reverse of what Ohio or Tennessee ask. We read the ADAI pages and forms on 2026-10-01, and the fees below are as those documents state them.

Rule 80-10-9-.28 never mentions lawn work

The Professional Services Rules require coverage of at least $150,000 before a permit issues for wood-destroying organisms, industrial, institutional and household pest control, and fumigation. Wood-destroying work adds $100,000 for errors and omissions. That is the whole list. The PDF ADAI links is a 2012 supplement, but the legislature's Administrative Code showed the same text on 2026-10-01, with no amendment after 2001.

State law leaves the door open. Section 2-28-10.1 lets the commissioner require indemnity or a surety bond for any professional permit. The horticulture license application asks for no insurance form, and the only insurance form on the professional services page is the structural certificate. A customer whose fescue browns after a bad mix will not care that the rule is silent, so read the pesticide applicator insurance guide before you buy a policy.

OTPS is the lawn category, and weed control sits inside it

The rules define Ornamental and Turf Pest Control as treating pests of ornamental plants, shade trees and turf, and they define "pest" to include weeds. Chapter 28 separately defines weed control work as spraying any plant that grows where it is not wanted for a fee. Herbicide on a customer's lawn belongs here.

Don't confuse it with OTPC, the custodial version for salaried staff at golf courses, apartment complexes, municipalities and similar employers. The Extension service republishing ADAI's instructions says those holders cannot charge the public. Landscape design, setting of plants and tree surgery are their own horticulture categories with separate exams.

A first year costs $295 to $345

ItemAmount
OTPS exam, paper in Montgomery$75
OTPS exam, computer site$125 ($75 state fee plus $50 administrative)
Commercial applicator permit$45 per category
Horticulture Professional Services license$175 a year

Add the license, the permit and the exam and a new company is out $295 by the paper route and $345 by computer, our sum from the amounts above.

Exam first, then the permit, then the business license

  1. Study. ADAI says it no longer prints study material. The commercial applicator page sends you to Alabama Extension, whose OTPS page lists the OTPS manual and a turfgrass pest guide and says the exam is 50 questions. The ADAI schedule lists OTPS as one $75 exam with no separate core exam.
  2. Write a qualification statement. The exam application wants your employer's name, dates and the type of work, with course copies if you cite schooling.
  3. Apply and sit the exam. Paper exams run on the third Tuesday of March, June, September and December, so the next one is December 15, 2026, then March 16, 2027. Bring a check or money order, because the schedule bars cash and cards. Computer exams are weekly at eight sites, with Extension listing Athens, Auburn, Birmingham, Hanceville, Headland, Millbrook, Mobile and Pelham.
  4. Apply for the commercial applicator permit within one year of passing, or the exam is void, per the Extension copy of ADAI's instructions.
  5. File the business license if you are starting a company. The license application says the certified operator is responsible for work performed by the licensee.

Three documents give three lead times for a paper exam application. The exam application says seven days, the rule says thirty days, and the Extension copy of ADAI's instructions says ten business days. Get a date in writing from 334-240-7243.

The license year turns over on October 1

Horticulture licenses run October 1 to September 30, and the new year began the day we read these pages. The license application says a company is delinquent as of October 1, with civil penalties of up to $3,000. Rule 80-10-9-.03 instead adds a $50 penalty when the fee is not paid by November 1 or within 31 days of its due date, and the Extension copy of ADAI's instructions says renew before November 1. Treat October 1 as the deadline until ADAI tells you otherwise. The permit renewal form linked from the commercial applicator page returned a not-found error when we tried it.

Under the same rules, every vehicle used for the work carries the permittee's name in letters at least three inches high on a contrasting background. Pesticide use records (product, amount, site, pest, date) are kept a year from the last treatment.

Thirty points keep the permit alive

Permits renew on a three-year cycle and need 30 continuing education points, per the Extension copy of ADAI's instructions. A $75 recertification exam, priced on ADAI's schedule, covers a shortfall. An Extension FAQ from 2022 adds that a permit expired more than a year means retraining and retesting. Points are searchable on ADAI's applicator search.

The same FAQ lists reciprocity with Florida, Georgia, Indiana, Louisiana, Mississippi, Ohio, South Carolina and Tennessee, and says the General Standards exam is not required for OTPS on that route. Holders of Georgia credentials should start there. The hub table shows how other states compare.

No ADAI page we read says whether fertilizer-only work needs a license.
