Crop Protection Technology Course

Lesson 1 • Crop-Pest Interaction Dynamics

Examines how host plant physiology, environment, and pest pressure interact to determine damage severity. Provides the ecological context needed for later integrated management chapters.

Lesson 2 • Major Pest Categories and Biology

Surveys insects, pathogens, weeds, nematodes, and vertebrate pests with emphasis on life cycles. Understanding biology is prerequisite to selecting appropriate control tactics.

Lesson 3 • Economic Injury Levels and Thresholds

Introduces economic injury level and action threshold concepts for rational intervention timing. Students calculate thresholds using crop value, control cost, and pest density data.

Lesson 1 • Pesticide Fate in the Environment

Analyses degradation pathways, soil adsorption, leaching potential, and volatilisation of pesticide residues. Environmental fate data inform application timing and site selection to minimise off-target impact.

Lesson 2 • Pesticide Toxicology and Safety

Covers acute and chronic toxicity endpoints, exposure routes, and signal word interpretation. Toxicological literacy is essential before students proceed to application and handling chapters.

Lesson 3 • Modes of Action by Pest Type

Explains biochemical target sites for insecticides, fungicides, herbicides, and nematicides. Linking mode of action to pest biology enables rational product selection and resistance management.

Lesson 4 • Formulation Types and Adjuvants

Describes emulsifiable concentrates, wettable powders, granules, suspension concentrates, and microencapsulated products. Adjuvant selection directly affects spray coverage, uptake, and efficacy.

Lesson 1 • Regulatory Frameworks for Pesticide Use

Surveys pesticide registration processes, maximum residue limits, and restricted-use classifications across regulatory systems. Compliance knowledge protects operators, consumers, and market access.

Lesson 2 • Safe Storage, Transport, and Disposal

Establishes protocols for pesticide storage segregation, container labelling, transport compliance, and triple-rinse disposal. Proper handling prevents accidental exposure and environmental contamination.

Lesson 3 • Personal Protective Equipment Selection

Matches PPE categories to pesticide hazard levels and application methods using label and SDS guidance. Correct PPE selection is a prerequisite for all hands-on application training.

Lesson 1 • Sprayer Calibration Methods

Teaches volume-per-area calibration using catch-jar, timed-run, and electronic methods for boom and knapsack sprayers. Calibration errors directly cause under- or over-dosing with agronomic and legal consequences.

Lesson 2 • Equipment Maintenance and Decontamination

Details cleaning protocols, component inspection schedules, and decontamination procedures between products and crops. Proper maintenance prevents cross-contamination, equipment failure, and phytotoxicity.

Lesson 3 • Nozzle Technology and Spray Quality

Explains nozzle types, droplet size spectra, and their effect on coverage, drift, and biological efficacy. Nozzle selection is the primary variable controlling spray quality in any application system.

Lesson 4 • Spray Drift Assessment and Mitigation

Quantifies drift risk factors including wind speed, temperature inversion, nozzle choice, and boom height. Drift mitigation protects non-target crops, water bodies, and neighbouring communities.

Lesson 1 • Pre-Emergence and Post-Emergence Programmes

Contrasts soil-applied residual programmes with foliar post-emergence applications and explains how each fits into a season-long strategy. Timing relative to weed and crop growth stage determines efficacy.

Lesson 2 • Herbicide Resistance Management

Explains resistance mechanisms, documents confirmed resistant biotypes, and prescribes rotation and diversification strategies. Resistance management is the most critical long-term challenge in chemical weed control.

Lesson 3 • Herbicide Classification and Selectivity

Categorises herbicides by site of action, chemical family, and selectivity mechanism including differential absorption and metabolism. Classification knowledge is foundational to resistance management planning.

Lesson 1 • Mite Biology and Acaricide Use

Distinguishes spider mite, rust mite, and predatory mite biology and explains acaricide selectivity and resistance. Preserving predatory mites through selective acaricide use reduces secondary pest outbreaks.

Lesson 2 • Biological Control Integration

Introduces parasitoids, predators, and entomopathogens as components of insect management programmes. Compatibility of biological agents with insecticides determines programme design and application timing.

Lesson 3 • Insecticide Groups and Resistance

Reviews major insecticide chemical classes, their target sites, and documented resistance cases in key pest species. Rotating insecticide groups is the primary tactic for preserving long-term efficacy.

Lesson 4 • Pollinator Protection Strategies

Identifies insecticide risk to managed and wild pollinators and prescribes label-compliant application timing and product choices. Pollinator protection is a regulatory and ecological obligation in modern crop protection.

Lesson 1 • Fungicide Chemistry and Modes of Action

Classifies fungicides by FRAC group, biochemical target, and spectrum of activity against oomycetes, ascomycetes, and basidiomycetes. Mode-of-action knowledge is essential for resistance management programme design.

Lesson 2 • Fungicide Resistance Management

Explains single-site vs. multi-site resistance risk, documents high-risk pathogen-fungicide combinations, and prescribes mixture and rotation strategies. Resistance management preserves the limited fungicide modes of action available.

Lesson 3 • Plant Disease Diagnosis and Epidemiology

Teaches symptom-based diagnosis of fungal, bacterial, viral, and abiotic disorders and explains disease triangle principles. Correct diagnosis prevents misapplication of fungicides and guides appropriate management tactics.

Lesson 4 • Seed Treatment and Soil Fungicide Use

Covers fungicide seed treatment formulations, application equipment, and soil drench programmes for soilborne pathogens. Seed treatments provide early-season protection with minimal environmental load compared to foliar programmes.

Lesson 1 • Communicating IPM to Stakeholders

Develops skills for presenting IPM recommendations to growers, agronomists, and supply chain partners using data-driven reports. Effective communication is essential for adoption of science-based pest management practices.

Lesson 2 • Cultural and Physical Control Tactics

Evaluates crop rotation, resistant varieties, sanitation, tillage, and physical barriers as foundational IPM components. Cultural tactics reduce pest pressure before chemical inputs are considered.

Lesson 3 • IPM Principles and Decision Framework

Defines IPM philosophy, the role of economic thresholds, and the hierarchy of control tactics from prevention to chemical intervention. This framework integrates all previous chapters into a unified decision-making system.

Lesson 4 • Designing a Season-Long IPM Programme

Guides students through building a crop-specific IPM calendar integrating scouting, thresholds, and tactic sequencing. Programme design requires synthesising pest biology, crop phenology, and economic data from all prior chapters.
