Research window: 2019 baseline through September 2026. Include older foundational studies where they remain the best evidence. Record access dates for every source.

1. How to research this part

  • Treat every named product, company, active ingredient status, date, and rule in this brief as a lead to verify, not a fact. It was drafted without live research.

  • Targets for this part:
    • At least 175 input product records (biopesticides, biofungicides, mineral fungicides, beneficial organisms, pheromones, organic herbicides, adjuvants).
    • At least 40 equipment or material records for physical controls (netting, traps, flame weeders, tarps) that cross-reference Parts 03–05.
    • At least 60 study records, including efficacy trials and resistance reports.
    • At least 25 regulation records (EPA registrations and reviews, EU active substance approvals and non-renewals, copper rules, drift rules).
    • At least 20 enforcement, recall, drift, or litigation event records.
    • Crop–pest management profiles for at least 20 key pests, 15 diseases, and 10 weed situations.
