1.1 Six named pests that could affect a nursery crop, and three beneficial organisms that could predate or parasitise them, are recognised at different stages of their life cycle.
1.2 Signs or symptoms of six diseases of nursery crops are recognised, and the disease named correctly at different stages of its life cycle.
Outcome 2
Monitor organism numbers.
Evidence requirements
2.1 Disease signs or symptoms are counted on random plants, and are reported when numbers reach a stated threshold level.
2.2 Traps are monitored and cleaned regularly, and when a threshold number of specific insects are caught, that fact is reported in accordance with workplace procedures.

Outcome 3
Select agrichemicals to rectify an imbalance in the pest-to-predator or -parasite ratio.
Evidence requirements
3.1 Agrichemicals injurious to named beneficial insects are recognised, and alternatives, non injurious to beneficial insects, are suggested.
3.2 Agrichemicals, application rates, and timing are suggested to redress the balance between pests and parasites or predators, or to reduce any potential disease problem.

Please note

Providers must be granted consent to assess against standards (accredited) by NZQA, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment.

Industry Training Organisations must be granted consent to assess against standards by NZQA before they can register credits from assessment against unit standards.
Providers and Industry Training Organisations, which have been granted consent and which are assessing against unit standards must engage with the moderation system that applies to those standards.
Requirements for consent to assess and an outline of the moderation system that applies to this standard are outlined in the Consent and Moderation Requirements (CMR). The CMR also includes useful information about special requirements for organisations wishing to develop education and training programmes, such as minimum qualifications for tutors and assessors, and special resource requirements.
