Core Responsibilities

Primary Functions

Conduct systematic, detailed inspections of all plant material, including plugs, liners, and finished products, to detect the presence of insects, mites, diseases, and physiological disorders.
Perform routine scouting and monitoring of crops throughout the greenhouse facility, following established protocols to ensure comprehensive coverage and early detection of potential issues.
Accurately identify common and uncommon horticultural pests, plant pathogens, and nutritional deficiencies using visual inspection, magnifying tools, and basic diagnostic kits.
Collect and prepare plant tissue, soil, and water samples for submission to internal or external laboratories for detailed analysis and definitive diagnosis.
Maintain meticulous, organized, and timely records of all scouting activities, inspection findings, and pest/disease population counts using digital software or physical logs.
Grade and sort plants according to established company quality standards, considering factors like size, color, uniformity, foliage density, and overall plant vigor.
Monitor and document environmental conditions within the greenhouse—including temperature, humidity, and light levels—to identify factors that may contribute to plant stress or disease outbreaks.
Implement and enforce strict sanitation and biosecurity protocols to prevent the introduction and spread of pests and pathogens between greenhouse sections and from outside sources.
Issue internal non-conformance or "hold" reports for plant material that does not meet quality specifications and collaborate with growing teams to determine the root cause and corrective actions.
Verify that all outgoing plant shipments comply with relevant state, federal, and international phytosanitary regulations, including proper documentation and certification requirements.
Oversee the strategic placement and routine monitoring of yellow/blue sticky cards and other trapping tools to track insect pest populations and inform treatment decisions.
Evaluate the efficacy of applied pest control measures—whether chemical, biological, or cultural—and provide objective feedback to the pest management and growing teams.
Ensure all pesticide application records are accurately maintained in compliance with Environmental Protection Agency (EPA) and state-level regulations, such as the Worker Protection Standard (WPS).
Conduct final, thorough pre-shipment inspections to guarantee that products meet or exceed customer quality expectations and align perfectly with order specifications.
Isolate and clearly tag infested or diseased plant material for treatment or culling, effectively communicating the necessary actions to the relevant greenhouse staff to prevent cross-contamination.

Secondary Functions

Assist in the development, implementation, and continuous refinement of the facility's Integrated Pest Management (IPM) program and overall plant health strategy.
Collaborate closely with growers and section managers to communicate inspection findings, discuss trends, and recommend data-driven adjustments to cultural practices.
Provide hands-on training and guidance to greenhouse technicians and staff on the proper identification of common pests, diseases, and key quality issues.
Stay current on emerging pest and disease threats to the horticultural industry and new advancements in diagnostic techniques and sustainable control technologies.
Contribute to the creation and updating of Standard Operating Procedures (SOPs) related to quality control, scouting protocols, and facility sanitation.
Manage and maintain a working inventory of all inspection tools, diagnostic equipment, personal protective equipment (PPE), and scouting supplies.
Participate in internal and external quality audits, providing necessary documentation and expert insights into the greenhouse's quality assurance processes.
Analyze scouting data to identify trends, persistent hotspots, and seasonal pest/disease patterns, generating summary reports for management to inform strategic decisions.

Required Skills & Competencies

Hard Skills (Technical)

Pest & Disease Identification: Expert ability to visually identify a wide range of horticultural insects, mites, bacteria, fungi, and viruses at various life stages.
Integrated Pest Management (IPM): Strong practical and theoretical knowledge of IPM principles, including biological, cultural, mechanical, and chemical control methods.
Horticultural Knowledge: A solid understanding of plant physiology, nutrition, and the specific environmental needs of various ornamental or vegetable crops.
Data Collection & Reporting: Proficiency in using mobile applications, spreadsheets (e.g., Excel), and specialized scouting software for accurate data entry, basic analysis, and clear report generation.
Regulatory Compliance: Familiarity with key state and federal agricultural regulations, including the Worker Protection Standard (WPS) and phytosanitary shipping requirements.
Diagnostic Sampling: Skill in properly collecting and handling plant, soil, and water samples without contamination to ensure accurate laboratory analysis.

Soft Skills

Meticulous Attention to Detail: The critical ability to spot minute imperfections, early-stage symptoms, or tiny pests that are easily overlooked by an untrained eye.
Exceptional Observational Skills: A keen and patient eye for noticing subtle changes in plant health, growth patterns, or the surrounding greenhouse environment.
