Pesticide Application Procedures

Task Description

Standards

In this activity, students will

  • create a presentation explaining the process to determine the amount of and application process to apply a pesticide.

Greenhouse Management, Standard 23: Identify the types of pesticides and their applications for greenhouse production. Research the safety hazards associated with pesticide use for multiple greenhouse pesticides. Calculate proper formulations of pesticides based upon label directions for specific pests by creating systems of equations that describe numerical relationships.

 Content Understandings

Extending Understandings

Upon successful completion of these tasks, students will demonstrate the ability to:

    • explain how to calibrate of pesticide application equipment,
    • determine the application rate, and
    • demonstrate how to determine the amount of pesticide concentrate and diluent to use.

To move students towards deeper understanding, they should be given opportunities to:

  • research methods to reduce pesticide spray drift, and
  • explain why it isimportant to regularly calibrate equipment before applying any chemical.

Support Strategies

If students are struggling to access this task, additional supports and strategies could be employed as students are engaging with the task.

Task Activity Steps

  1. Students will create a presentation explaining the pesticide application process and how to determine the amount of pesticide to apply.
  2. The presentation should explain how a person can safely:
    1. calibrate the application equipment being used to apply the pesticide,
    2. determine the application rate of the chosen pesticide, and
    3. show how to determine the amount of pesticide concentrate and diluent needed to mix the pesticide.
  3. To assist with the presentation, teachers can recommend/modify the following:
    1. Students can use a flower bed or landscaped area located near their residence to determine the square footage and plants to be treated.
    2. Depending on the time of the year for this activity, the teacher may need to provide the student with a list of pest and plants to be treated with either herbicides or insecticides common for the area.
  4. The teacher will provide grading expectations and submission directions to the students.
