                               modes of action of agrichemicals agrichemical formulations; the
                               uses of spray additives; resistance to agrichemicals; and

        Environmental fate – a generic term describing the interaction of the product, or
        substance concerned, with the environment, including descriptions of:
        a    the various pathways by which a substance may enter and transferred within
             the environment;
        b    the possible interactions with the environment;
        c    the consequences of these interactions, especially where there is potential for
             adverse environmental effect;

      flora and fauna. It is a subset of agricultural compounds and includes pesticides,
      spray additives, fertilisers, vertebrate pest control products, and oral nutrition
      products.

      amenity turf, sports turf.
      Specified primary sector industry may be any subsector of a specified primary sector,
      for example, agriculture – dairy, sheep; equine – sport horse, racing; forestry –

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.
