Integrated pest management, prevention, scouting, sanitation, exclusion, thresholds, records, and biosecurity.
Published lessons
These pages are organized here by subject. The permanent THC-ENC IDs remain stable behind the scenes even when a clearer display title is used.
IPM Principles and the Prevention Hierarchy
Explain integrated pest management as a recurring evidence-based decision process that prioritizes prevention, monitoring, correct identification, context-specific action thresholds, lower-risk interventions, and verification rather than routine calendar pesticide use.
Facility Zoning and Clean-to-Dirty Workflow
Design plant-health work flow so people, tools, carts, plant material, and waste move in ways that reduce transfer from suspect, infested, or contaminated areas into cleaner propagation and production zones.
Plant Intake and Quarantine
Use receiving inspection, source records, physical separation, appropriate testing, and defined release criteria to reduce the chance that incoming Cannabis/hemp plants introduce pests or pathogens into established production.
Personnel Entry and Clothing Controls
Explain how hands, footwear, clothing, gloves, and work sequence can move pests, soil, sap, and plant pathogens, and how plant-health entry controls reduce transfer without implying that personnel movement alone proves an outbreak source.
Tool, Bench, and Container Sanitation
Distinguish physical cleaning from subsequent sanitation/disinfection and apply traceable surface-control practices to tools, benches, reusable containers, hose ends, and other crop-contact equipment without inventing universal chemical concentrations or contact times.
Cleaning Versus Disinfection
Separate physical removal of contamination from microbial inactivation so sanitation procedures are designed as validated sequences rather than treating a disinfectant application as a substitute for cleaning.
Disinfectant Contact Time and Surface Preparation
Explain why disinfectant performance depends on prepared surfaces, effective wet/contact time, product concentration/formulation, surface compatibility, and target-organism evidence rather than product name alone.
Water-System and Irrigation-Line Hygiene
Explain how irrigation sources, reservoirs, recirculating systems, hose ends, lines, emitters, and biofilm can become plant-health transfer pathways, and how source control, maintenance, targeted testing, and validated treatment reduce risk without equating microbial detection with disease.
Pest Exclusion and Structural Sealing
Explain how screening, door and vent management, structural sealing, receiving controls, and exterior maintenance reduce pest entry while preserving ventilation, access, and operational safety.
Environmental Management for Disease Prevention
Explain how temperature, humidity, condensation, air movement, plant density, irrigation, and root-zone moisture change disease pressure, while avoiding unsupported universal Cannabis setpoints.
Scouting Routes and Representative Sampling
Build repeatable scouting routes and representative sampling plans that detect pest and disease trends early, cover crop and risk zones systematically, and preserve enough denominator and location information for meaningful decisions.
Pest and Disease Identification Escalation
Use an evidence-based escalation path from field observation to magnification, reference comparison, representative sampling, and laboratory diagnostics so management actions are not built on symptom guessing or overconfident identification.
Thresholds, Tolerances, and Decision Records
Use thresholds and tolerances as explicit, evidence-bounded decision tools that combine monitoring data, crop stage, injury, vector/disease risk, crop value, beneficial organisms, and uncertainty rather than inventing universal Cannabis treatment numbers.
Cultural Controls
Use crop, irrigation, fertility, sanitation, host, spacing, timing, weed, and environmental practices to make pest establishment and disease development less favorable while preserving plant health and documenting tradeoffs.
Mechanical and Physical Controls
Apply barriers, exclusion, trapping, removal, pruning, isolation, environmental or process-based physical methods, and other nonchemical interventions according to target biology, scale, crop stage, and measurable effectiveness.
