Performance Evidence

The candidate must be assessed on their ability to integrate and apply the performance requirements of this unit in a workplace setting. Performance must be demonstrated consistently over time and in a suitable range of contexts.

The candidate must provide evidence that they can:

recognise plant pests, diseases and disorders

identify interrelationships between weedy plants, pests, diseases or disorders and weather or environmental conditions

recognise treatment or response methods, or opportunities

prepare and apply treatments or responses to threats

---

Knowledge Evidence

The candidate must demonstrate knowledge of:

permaculture principles and practices in regard to plant protection, such as:

creative solutions to common problems in a permaculture system

design for improved predator-pest balance

integrated plant and animal systems

guilds of planting for mutual support

mineral contribution of weeds to soil (bioaccumulation)

using pest-weed cycles to advantage (breaking the insect reproductive cycle for example)

common weedy plants, plant pests, diseases and disorders

common environmental impacts on permaculture systems

fire, flood, storm and tsunami behaviours and precautions relevant to permaculture design

different types of treatments or system modifications and their principles, such as:

non-chemical controls including sprays with organic or natural ingredients

cultural control methods

animal systems to control plants or plant residues (chicken or pig tractors)

shade used as a control

biodynamic treatments and control measures

sheet mulching

composting of residues

follow-up strategies including spot mulching, seedling disturbance, animals

environmental considerations when applying treatments
