SPORTS TURF WEEDS AND PESTS
Design weed control programmes for
sports turf surfaces
level:
6
credit:
15
planned review date:
March 2010
sub-field:
Sports Turf
replacement information:
This unit standard replaced unit standard 4275.
purpose:
This unit standard is for people who are required to design
weed control programmes for sports turf surfaces. People
credited with this unit standard are able to: use
information on the biology of weed species to identify
factors influencing the effectiveness of their control;
identify and determine the characteristics of a range of
weeds; evaluate herbicide mechanisms and effectiveness
to identify herbicides for control of given weed situations
without causing turf damage; and design and present a
weed control programme for a sports turf organisation.
entry information:
Open.
accreditation option:
Evaluation of documentation and visit by NZQA and industry.
moderation option:
A centrally established and directed national moderation
system has been set up by the Primary Industry Training
Organisation.
special notes:
1
For element 4 evidence submitted for assessment must
include the assessment of weed control needs of an
operational sports turf organisation. The evidence must
contain documented permission from that organisation
for the assessment to be undertaken.
Evidence submitted for assessment must be accurate,
written in a style and language which meets the client
organisation’s needs, requirements of current industry
practice, and the presentation standards generally
accepted for sports turf technical documentation.

principles and control programmes, soil seed bank, competitive
ability, allelopathy, flowering and seed setting, seed numbers,
dispersal, dormancy, weed seed germination, sexual and
vegetative reproduction, perennial versus annual growth habit.
Documented findings describe strategies which may be used in the
management of turf weeds.

strategies may include but are not limited to – soil shading,
germination periodicity, use of artificial media, selection and timing
of cultivation methods, dormancy management, stale seedbed
technique, artificial reduction of weed and seed population,
integrated weed control.

SPORTS TURF WEEDS AND PESTS
Design weed control programmes for
sports turf surfaces
element 2
Identify and determine the characteristics of weeds.
performance criteria
2.1

collection which meets the collection criteria established for this work.
Range:
2.2
collection criteria for this work includes but is not limited to – forty
weeds cited in the identified references, weeds selected are
relevant to the application of the work, mounting and labelling
conforms with accepted collection practice.
Procedures followed in collection of samples ensures correct identification and
detailing of characteristics of weeds.
Range:
procedures may include but are not limited to – selection of
flowering samples where possible, selection of samples with
sound leaf structure and condition, selection of samples with
distinguishable root structure, notes identifying date, location,
appearance and habitat of the sample when found.
element 3
Evaluate herbicide mechanisms and effectiveness to identify herbicides for control of
given weed situations without causing turf damage.
performance criteria
3.1
Documented findings identify significant details of herbicide toxicity and related
legislation.
Range:
significant details may include but are not limited to – historical
information, safety testing of herbicides, relative toxicity, relevant
New Zealand legislation and agrichemical law, GROWSAFE
scheme, herbicide residues, user safety.

Accredited providers and Industry Training Organisations assessing against unit standards
must engage with the moderation system that applies to those standards.
Accreditation requirements and an outline of the moderation system that applies to this
standard are outlined in the Accreditation and Moderation Action Plan (AMAP). The
AMAP also includes useful information about special requirements for providers wishing to
