    Lantra Awards Level 2 Award in the Safe Application of Pesticide using Vehicle Mounted or Trailed Wick Type Applicators

    Topic Overview

    This qualification covers the safe and effective use of vehicle-mounted or trailed wick-type applicators for pesticide application. It is designed for operators in horticulture, agriculture, and land management who need to apply herbicides to control weeds in crops, grasslands, or non-crop areas. The course emphasises legal compliance, environmental protection, and personal safety, aligning with UK regulations such as the Control of Pesticides Regulations (COPR) and the Sustainable Use Directive.

    Wick applicators are a targeted method for applying non-selective herbicides, such as glyphosate, by wiping the chemical onto weeds without spraying. This reduces drift, minimises off-target damage, and is ideal for spot-treating tall weeds in standing crops or around obstacles. Students learn to calibrate equipment, select appropriate nozzles or wicks, and adjust application rates to ensure efficacy while minimising environmental impact.

    Mastering this topic is essential for anyone involved in vegetation management, as it combines practical skills with legal knowledge. The qualification is part of the Lantra Awards suite, recognised by industry bodies like the National Register of Sprayer Operators (NRoSO) and the Continuing Professional Development (CPD) scheme. Understanding this method can improve efficiency, reduce chemical usage, and enhance your employability in the land-based sector.

    Key Concepts

    Core ideas you must understand for this topic

    • →Wick applicator design: Understand the components (wick material, feed system, boom height) and how they affect herbicide transfer to target weeds.
    • →Calibration: Accurately calculate the volume of herbicide solution applied per unit area (e.g., litres per hectare) to ensure correct dose and avoid under/over-application.
    • →Selective application: Recognise that wick applicators are best for non-selective herbicides; they must only contact target weeds, not desirable plants.
    • →Environmental safeguards: Prevent herbicide drift and runoff by using appropriate wick types, adjusting boom height, and avoiding application in windy or wet conditions.
    • →Legal compliance: Follow COPR, the Food and Environment Protection Act (FEPA), and the Health and Safety at Work Act; maintain records and hold a valid certificate of competence.

    Learning Objectives

    What you need to know and understand

    • 1. Understand the legislative and safety regulations relating to the use of application equipment2. Be able to assess the environmental factors to be considered when mixing, handling and applying pesticides3. Be able to interpret product label information4. Be able to prepare the application equipment 5. Be able to calibrate the application equipment6. Be able to operate the application equipment7. Understand how to carry out post-operational procedures

    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for demonstrating accurate interpretation of product label instructions specific to wick-type application, including mixing ratios and targeted weed species.
    • Award credit for correctly calibrating the wick applicator to deliver the specified application rate, showing all calculations and using an accepted calibration method.
    • Award credit for performing a thorough post-operational clean-down and decontamination of the vehicle-mounted or trailed equipment, in line with legal and environmental requirements.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Always cross-reference the product label for any specific instructions on using wick-type applicators, as they often differ from spray application advice.
    • 💡During practical assessments, verbalise your environmental risk assessment and demonstrate checking weather conditions before starting the application.
    • 💡Memorise the calibration formula and common conversion factors for wick-type equipment to reduce errors and save time in timed assessments.
    • 💡Show your working in calibration calculations: Examiners award marks for clear steps, including converting units and showing formulas. Always state the final dose in L/ha.
    • 💡Link theory to practice: When describing safety measures, mention specific PPE (e.g., nitrile gloves, waterproof trousers) and why they are needed for wick applicators (e.g., contact with herbicide-soaked wicks).
    • 💡Use correct terminology: Phrases like 'target weed,' 'non-target vegetation,' and 'application rate' demonstrate understanding. Avoid vague terms like 'stuff' or 'things'.

    Common Mistakes

    Common errors to avoid in your coursework

    • Misinterpreting product label rates, confusing wick application guidelines with those for conventional spraying.
    • Failing to check wind speed and direction before application, risking drift onto non-target plants or sensitive areas.
    • Neglecting immediate cleaning of wick applicator components after use, leading to blockages, chemical residue buildup, and cross-contamination.
    • Misconception: 'Wick applicators can be used with any herbicide.' Correction: Only non-selective herbicides (e.g., glyphosate) are suitable; selective herbicides may damage crops if wiped onto them.
    • Misconception: 'Calibration is unnecessary because the wick always delivers the same amount.' Correction: Calibration is critical because wick wear, speed, and herbicide concentration affect dose; regular checks ensure accuracy.
    • Misconception: 'Drift is impossible with wick applicators.' Correction: While drift is reduced, it can still occur if the wick is too wet, the boom is too high, or in strong winds; proper setup and weather checks are essential.
