TP Version




Initial release


This unit of competency describes the skills and knowledge required to prepare and apply chemicals for the control of pests across a range of industry sectors.

This unit covers the use of general application equipment used across a variety of industries including; boom sprays, orchard air-blast sprayers, handheld spray equipment, wipers, dry chemical applicators, dips, pour-on, spot-on, vaccination and drenching equipment.

All work must be carried out to comply with workplace procedures, work hand safety and pesticide legislation and codes.

All work must be carried out to comply with chemical label instructions, Safety Data Sheets (SDS’s), the organisation’s application plan and relevant legislation.

This unit applies to individuals who work under broad direction and take responsibility for their own work and use discretion and judgement in the selection and use of available resources.

Licensing, legislative, regulatory or certification requirements may apply to this unit. Candidates should confirm the regulatory requirements that apply in their relevant State or Territory before undertaking this unit.

This unit may be deemed to have a time limit when used as part of an accreditation or licence process.

Elements and Performance Criteria


Performance criteria

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

1. Determine the need for chemical use and prepare a application plan

1.2 Assess the requirement for chemical use as an option within an integrated pest management strategy

1.3 Undertake a hazard and risk analysis of different chemical options

1.4 Confirm requirement for chemical application

1.5 Assess the spray drift risk of various application options

1.6 Assess the risk to sensitive areas and environmentally sensitive organisms

1.7 Prepare application/spray plan where required

2. Prepare chemical mixes

2.1 Access the workplace application or spray plan to determine chemical and target, application rate or dose, type of application equipment, set-up requirements and amount to be applied as per the label instructions

2.2 Identify potential hazards, assess risks and implement control measures

2.3 Interpret and apply requirements from chemical labels

2.4 Select appropriate personal protective equipment (PPE) for each stage of work and ensure correct fit

2.6 Mix chemicals in accordance with registered use and clean equipment when finished task

2.7 Follow label instructions in the event of a spill

2.8 Confirm that neighbours have been notified of chemical application as appropriate

3. Calibrate application equipment

3.1 Select application equipment to be used to minimise spray drift risk and maximise efficacy

3.2 Carry out pre-operational checks of application equipment

3.3 Calibrate equipment in accordance with manufacturers’ specifications and application/spray plan.

3.4 Safely load chemical mix wearing appropriate Personal Protective Equipment (PPE) and controlling risks to human health and the environment

4. Apply chemicals

4.1 Monitor meteorological conditions and forecasts prior to and during application to minimise spray drift and other off target movement of chemicals

4.2 Select and use appropriate PPE in accordance with chemical label and SDS’s

4.3 Apply chemical in accordance with the label and application/spray plan

4.4 Assess and minimise risks to others, product integrity and the environment

4.5 Follow chemical spill or accident procedures in the event of a spill

  • use appropriate personal protective equipment
  • follow emergency procedures during an accident or spillage

Knowledge Evidence

The candidate must demonstrate knowledge of:

  • options for pest control based on the Integrated Pest and Resistance Management Plan
  • pest and/or disease resistance management
  • various chemical labels and SDS formats
  • impact of meteorological factors on the safe and effective application of chemicals
  • factors that determine spray drift risk including droplet size, wind speed, temperature and temperature inversions and approaches to controlling spray drift risk
  • risk factors including human and animal health, weather prior to, during and after application, spillage, residues in plants and animals consumed as food and environmental
  • how to mix chemicals including mixing order, adjuvants and water quality
  • requirements for disposal of excess chemicals, clearing spillages and equipment clean up
