    Lantra Awards Level 2 Award in The Safe Application of Pesticides Using Variable Geometry Boom or Broadcast Sprayers

    Topic Overview

    This qualification covers the safe and effective use of variable geometry boom or broadcast sprayers for applying pesticides in agricultural settings. It focuses on the practical skills and knowledge required to operate these sprayers, including calibration, maintenance, and adherence to legal and environmental regulations. Understanding this topic is essential for anyone involved in crop protection, as it ensures pesticides are applied accurately, minimising waste and environmental impact while maximising efficacy.

    The course is part of the Lantra Awards Level 2 suite, which is widely recognised in the UK agricultural industry. It builds on basic pesticide handling knowledge and emphasises the unique challenges of variable geometry booms, which adjust to different crop heights and widths, and broadcast sprayers used for large-area applications. Students will learn to select appropriate nozzles, calculate application rates, and conduct pre-operational checks to comply with UK legislation such as the Plant Protection Products (Sustainable Use) Regulations.

    Mastering this topic is crucial for reducing pesticide drift, protecting non-target organisms, and ensuring operator safety. It also contributes to sustainable farming practices by optimising chemical use. This qualification is often a prerequisite for commercial spraying operations and demonstrates competence to employers and regulatory bodies.

    Key Concepts

    Core ideas you must understand for this topic

    • →Calibration: Accurate calibration of sprayers to deliver the correct volume per hectare is critical. This involves measuring nozzle output, travel speed, and pressure to achieve the desired application rate.
    • →Variable Geometry Booms: These booms can adjust in width and height to match crop growth stages, reducing drift and improving coverage. Understanding how to set and maintain these adjustments is key.
    • →Nozzle Selection: Different nozzles produce different droplet sizes and spray patterns. Selecting the right nozzle for the target pest and crop reduces drift and ensures effective coverage.
    • →Environmental Protection: Operators must follow buffer zones, avoid water contamination, and consider weather conditions (wind speed, temperature) to prevent spray drift and protect wildlife.
    • →Legal Compliance: Adherence to the Code of Practice for Using Plant Protection Products, record-keeping, and holding a valid Certificate of Competence (e.g., NPTC PA1/PA2) is mandatory.

    Learning Objectives

    What you need to know and understand

    • 1. Understand the legislative and safety regulations relating to application equipment2. Be able to assess the environmental factors relating to mixing and application3. Be able to interpret product information4. Be able to prepare the application equipment5. Be able to calibrate the application equipment 6. Be able to operate the application equipment 7. Understand how to carry out post-operational procedures

    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Identifies legislative and safety regulations for sprayer operation.
    • Assesses environmental factors affecting application.
    • Interprets product information correctly.
    • Demonstrates correct calibration and operation of equipment.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Refer to specific regulations like COSHH and FEPA.
    • 💡Practice calibration calculations.
    • 💡Emphasise personal protective equipment (PPE).
    • 💡Tip 1: Always show your working in calibration calculations. Examiners award marks for correct methodology even if the final answer is slightly off. Use the formula: application rate (L/ha) = (nozzle output (L/min) × 600) / (speed (km/h) × nozzle spacing (m)).
    • 💡Tip 2: Emphasise safety and environmental considerations in your answers. Mentioning personal protective equipment (PPE), buffer zones, and wind speed limits (typically below 5 m/s) demonstrates a thorough understanding of responsible pesticide use.
    • 💡Tip 3: For variable geometry booms, explain how you would adjust the boom height and width for different crop stages. For example, lower booms reduce drift in early growth, while wider booms may be needed for mature crops.

    Common Mistakes

    Common errors to avoid in your coursework

    • Ignoring buffer zones or weather conditions.
    • Incorrect calibration leading to over- or under-application.
    • Failing to clean equipment after use.
    • Misconception: 'Higher pressure always gives better coverage.' Correction: Higher pressure can create finer droplets that are more prone to drift and may not penetrate dense canopies. Optimal pressure is determined by nozzle type and target.
    • Misconception: 'Calibration only needs to be done once a season.' Correction: Calibration should be performed regularly, especially after changing nozzles, pesticides, or when operating conditions change (e.g., different travel speeds).
    • Misconception: 'Broadcast sprayers are only for large fields.' Correction: While broadcast sprayers are efficient for large areas, they can also be used in smaller fields with careful adjustment of boom width and nozzle selection to avoid overapplication.
