    ASSESSMENT CRITERION 2 
    The reasons why the registration data of a herbicide must be known, is explained with regard to the specific function that the chemical is designed to perform and its residual efficacy period. 

    ASSESSMENT CRITERION 3 
    The necessity of being familiar with the active ingredient in the herbicide is explained within the context of ensuring that this information can be relayed to a doctor in case of an accidental poisoning. 

    ASSESSMENT CRITERION 4 
    The importance of determining the wind's direction and the reasons why an operator should work into the wind are explained in terms of the possibility of poisoning. 

    SPECIFIC OUTCOME 2 
    Identify at least 20 alien invader plants that are problematic in the region and examples of indigenous plants that may be used to replace the aliens. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    At least 20 alien invader plants found in the region are identified for the purpose of replacing them with environmentally compatible indigenous plants. 

    ASSESSMENT CRITERION 2 
    The significant characteristics of these alien invader plants, are described in terms of those specific features that allow their rampant establishment in the environment. 

    ASSESSMENT CRITERION 3 
    At least 20 indigenous plants that have similar physical attributes to the identified alien plants, are selected to replace these invader plants. 

    SPECIFIC OUTCOME 3 
    Conduct the biological control of alien invader plants. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    The advantages of utilising biological control for combating pests are described within the context of establishing an ecological balance. 

    ASSESSMENT CRITERION 2 
    The importance of conducting thorough research prior to the introduction of biological control agents, is explained in terms of ensuring that only the targeted alien plants are affected. 

    ASSESSMENT CRITERION 3 
    Examples of biological control agents that make a positive contribution to combating alien invader plants are described in terms of the specific pests that they control. 

    ASSESSMENT CRITERION 4 
    The procedures for the introduction of biological control agents into the area where invader plants have become established are demonstrated in accordance with the company's procedures. 

    ASSESSMENT CRITERION 5 
    The processes for the monitoring the effectiveness of the control agents, are demonstrated in accordance with the company's procedures. 

    SPECIFIC OUTCOME 4 
    Describe the various types of herbicides that may be used to control alien invader plants. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    The processes by which contact herbicides can eradicate invader plants is explained with regard to the damage that these chemicals inflict on the plants foliage and stems. 

    ASSESSMENT CRITERION 2 
    The processes by which systemic herbicides eradicate invader plants is explained in terms of their absorption by the plant and translocation to the various tissues that they destroy. 

    ASSESSMENT CRITERION 3 
    The distinction between selective and broad spectrum herbicides, is explained in terms of the varying susceptibility that different plants have in absorbing and translocating the active ingredients of these agents. 

    ASSESSMENT CRITERION 4 
    The methods by which hormone herbicides eradicate invader plants is explained in terms of their absorption by the plant and translocation to the various tissues that they destroy. 

    ASSESSMENT CRITERION 5 
    The importance of noting the residual period of herbicides before these are applied, is explained within the context of the time in which no further planting may occur in the immediate area around the treated zone. 

    SPECIFIC OUTCOME 5 
    Prepare the herbicide solution and apply this to the selected alien invaders. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    The necessity of calculating the volume of the herbicide solution that is required, before any mixing takes place, is explained in terms of the wastage that may occur if too much solution is made and the possibility of environmental pollution, should the balance be thrown away. 

    ASSESSMENT CRITERION 2 
    The methods of mixing the solution to ensure that the correct concentration are demonstrated in accordance with the company's procedures. 

    ASSESSMENT CRITERION 3 
    The importance of completing the calibration calculations before the solution is applied, is explained with regards to the possible problems that may occur, if the incorrect application rate is used. 

    ASSESSMENT CRITERION 4 
    The methods of calculating the calibration data are demonstrated in accordance with the company's procedures. 

    ASSESSMENT CRITERION 5 
    The danger that "runoff" water from hard surfaces that have been treated with broad spectrum herbicides poses to the environment, is explained in terms of the damage that may be inflicted to neighbouring plants. 

    ASSESSMENT CRITERION 6 
    The safety precautions and operating procedures that must be followed when using a knapsack sprayer to apply the herbicide solution to the selected invaders, are demonstrated in accordance with the company's procedures. 

    ASSESSMENT CRITERION 7 
    The advantages of "painting" the applicable systemic herbicide solution onto the stump or cut out wedge of a large invader plant or tree, are listed and the procedures to conduct these procedures are demonstrated in accordance with the company's procedures. 

    ASSESSMENT CRITERION 8 
    The safety precautions and housekeeping practices for the cleaning, aeration and storage of the herbicide applicators and equipment are described in accordance with the company's procedures.
