Office of Indiana State Chemist (OISC) — Pesticide Section is the lead agency. Its site, oisc.purdue.edu, carries the current applications, category list and exam scheduling.
Purdue Pesticide Programs (Purdue Extension) publishes the study materials: ag.purdue.edu. The extension-manual method, core first, then categories, then whole-label practice, is the study approach that matches how these exams are written.
The framework underneath
Every state plan implements the same federal standards: private vs commercial certification, written competency demonstration, minimum age 18, the category system for commercial work, and the five-year federal expiration with renewal by exam or approved continuing education. The full verified reference covers it, and the category pages walk every federal category. The step-by-step path is inhow to get a pesticide applicator license, and renewal is covered in applicator recertification.
The label is the law
Nothing here is use guidance. The product label is the controlling legal document for any application decision, everywhere, in every state.
