A curated collection of authoritative resources for agricultural chemical professionals, licensed pesticide applicators, crop consultants, and producers. This directory covers regulatory compliance, safety, pest management, and chemical application best practices.
Regulatory & Compliance Resources
EPA Office of Pesticide Programs — The U.S. Environmental Protection Agency's central hub for pesticide regulation, label databases, and tolerance information. Search registered products, read tolerance exemptions, and download official label documents for any federally registered pesticide.
Texas Department of Agriculture — Pesticide Programs — Texas TDA administers licensing for commercial pesticide applicators, regulates restricted-use pesticide (RUP) sales, and enforces label compliance. Find licensing requirements, continuing education (CEU) providers, and enforcement actions here.
California Department of Pesticide Regulation — CDPR maintains one of the most comprehensive pesticide use reporting databases in the world. Useful for understanding national regulatory trends, especially for operations selling into California markets.
National Pesticide Information Center (NPIC) — NPIC is a cooperative effort between Oregon State University and the EPA. Provides unbiased, science-based information on pesticide ingredients, toxicology, and exposure incidents. Call 1-800-858-7378 for live expert assistance.
Safety Data Sheets & Chemical Information
OSHA Hazard Communication Standard (HazCom 2012) — OSHA's HazCom standard requires SDS for all hazardous chemicals. This page explains the 16-section GHS format, employee right-to-know requirements, and employer obligations for maintaining accessible SDS binders at worksites.
CHEMTREC Emergency Response — CHEMTREC provides 24/7 emergency chemical incident response for transportation accidents and facility spills. All commercial pesticide distributors should register products with CHEMTREC. Emergency line: 1-800-424-9300.
PubChem (NIH/NLM) — PubChem is the world's largest free chemistry database, maintained by the National Institutes of Health. Look up active ingredient structures, toxicology data, LD50 values, and peer-reviewed safety studies for any pesticide active ingredient.
Integrated Pest Management & Extension Resources
Texas A&M AgriLife Extension — Pest Management — AgriLife Extension publishes free, peer-reviewed pest management guides for every major Texas crop, including cotton, corn, wheat, and sorghum. Guides cover economic thresholds, scouting methods, and recommended pesticide programs updated annually.
USDA IPM Centers Data — The USDA-funded Regional IPM Centers aggregate research-based IPM information from land-grant universities nationwide. Search by crop, pest, or state for locally relevant IPM recommendations and resistance management strategies.
USDA Agricultural Research Service — Crop Protection — ARS conducts cutting-edge research on pesticide efficacy, resistance mechanisms, and new pest control technologies. Publications are peer-reviewed and freely accessible through the ARS website.
Herbicide Resistance Action Committee (HRAC) — HRAC maintains the global database of confirmed herbicide-resistant weed biotypes. Search by species, active ingredient, or mode of action group to identify resistance issues in your region before they impact your operation.
Professional Organizations
National Pest Management Association (NPMA) — NPMA represents over 5,500 pest management companies. Offers training programs, certification pathways (QualityPro), regulatory advocacy resources, and industry news relevant to commercial pesticide applicators.
Weed Science Society of America (WSSA) — WSSA publishes the authoritative herbicide classification system used on all U.S. herbicide labels. Access the Herbicide Handbook, resistance management guidelines, and the journal Weed Science.
Entomological Society of America (ESA) — ESA is the world's largest organization serving the entomological sciences. Access peer-reviewed journals, insecticide resistance reports, and guidance on beneficial insect conservation as part of IPM programs.
