A plain-English walkthrough of getting certified in Louisiana — commercial versus private certification, the General Standards and category exams, what it costs, and how to study and pass. Pesticide certification in Louisiana is run by the Louisiana Department of Agriculture and Forestry (LDAF), with study manuals through the LSU AgCenter.
Commercial candidates pass the General Standards exam (free) plus category exams at $50 each — mail the completed exam application and payment to LDAF first, then schedule. Louisiana changed its testing system in late 2025: exams now run in person at the LDAF main office in Baton Rouge or remotely through Everblue (the online vendor adds its own access fee). The study text is the National Pesticide Applicator Certification Core Manual from the LSU AgCenter — the exact national foundation our practice bank drills.
The commercial certification card renews at $20 per year, and certification itself is maintained by attending an approved one-day recertification meeting (or retesting) every three years — the date on the back of your card. Private certification is $25 for three years with the same recert-meeting-or-retest cycle, plus restricted-use record keeping. Companies making recommendations for a fee need the separate Agricultural Consultant license. Confirm current fees with LDAF.
Louisiana runs two clocks that are easy to confuse. The applicator card on the front shows an annual expiration — LDAF mails renewal information each year to keep the card active at about $20. The date on the BACK of the card is the one that matters for certification: commercial certification lasts three years from when you were certified or last recertified, maintained by attending one approved one-day recertification meeting (you complete a form before leaving to get credit) or by retesting. Private certification runs three years on the same meeting-or-retest cycle. Confirm your back-of-card recertification date with LDAF before it lapses.
The General Standards exam is free; category exams are $50 each, with the application and payment mailed to LDAF before scheduling. Online testing through Everblue adds a vendor access fee. Confirm current fees with LDAF.
Since the late-2025 testing transition: in person at the LDAF main office in Baton Rouge, or online with remote proctoring through Everblue. District-office testing ended in October 2025.
Commercial certification is good for three years from certification or last recertification — attend an approved one-day recertification meeting (or retest) by the date on the back of your card, and renew the $20 annual card each year. Private applicators follow the same three-year meeting-or-retest cycle.
