Application
This unit of competency describes the skills and knowledge required to test annual ryegrass seed for nematode gall (Anguina spp.).
It applies to senior seed analysts who analyse information and exercise judgement to complete a range of advanced skilled activities and demonstrate deep knowledge in a specific technical area. They have accountability for the work of others and analyse, design and communicate solutions to a range of complex problems. All work is carried out to comply with workplace procedures.
No occupational licensing, legislative or certification requirements are known to apply to this unit at the time of publication.
Elements and Performance Criteria
Element | Performance criteria |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Prepare for Anguina testing | 1.1 Review test request to identify samples to be tested, required test methods, equipment and staff to be involved in the test 1.2 Clean and calibrate equipment and working space 1.3 Prepare the working sample or sub-samples using mixing and dividing processes 1.4 Record sample details on worksheets and sample packets |
2. Inspect seed samples | 2.1 Inspect a prescribed sample weight of ryegrass seed on a diaphanoscope for the presence of galls 2.2 Separate any galls present into yellow and black galls, count and report separately |
3. Examine galls | 3.1 Soak galls in water for prescribed period 3.2 Dissect galls and examine under a microscope for the presence of nematodes 3.3 Record the presence of nematodes |
4. Report results | 4.1 Review testing procedures carried out by analysts 4.2 Issue a report of ‘no galls found’ where no galls are found on the prescribed weight of seed 4.3 Report as ‘number of galls per sample weight’ where galls containing nematodes have been detected |

basic nematode identification
enterprise standard operating procedures (SOPs)
recording and reporting protocols
relevant health, safety and environment requirements
seed biology
Assessment Conditions
Assessors must satisfy current standards for RTOs.
