Pesticide Applicator: Pesticide Formulations, Equipment, and Calibration - The One With All the Math

Due to demand, we are opening registration for this program soon! If you fill out the request form, we can alert you when it's available.
One of the most challenging aspects of application is the math involved. We’ve got you covered with this course! 

Math Made Easy

In this online course, you'll learn about:

  • pesticide formulations
  • how to calibrate application equipment
  • the importance of examining the label for application rate restrictions.

Remember, safely applying pesticides requires understanding of how much product is being used. The amount of pesticide to 'add to the tank' depends on the output of the equipment, the size of the application area, and the label-listed rate.

Course Overview

In this course, we review the basic math principles involved in converting between units and calculating. Been a while since you reviewed fractions and geometry? That's ok! With this course, we start at the beginning, and offer plenty of opportunity to practice.

By the end of this course you will be able to:

  • Distinguish between active and inert ingredients.
  • State the meaning of abbreviations used for common types of formulations (e.g., WP).
  • List the factors to consider when choosing a formulation for a specific site or situation.
  • Name several different application procedures and types of equipment
  • Identify the factors (eg nozzles, volumes, pressures and speeds) that affect calibration explain the importance of calibrating equipment
  • Calculate the size of an application area
  • Understand how the amount of product used relates to rate and spray area
  • Determine the amount of pesticide concentrate and diluent to use
