One of the most important things that can be done when using herbicides is making sure you are spraying the right plant and you are using the right amount of herbicide. Learning how to use the right amount of herbicide is called calibration.
There are many ways a person can learn about calibration.
- Contact your local weed coordinator or extension agent.
- Attend a Private Applicator’s Class in your area.
- Use a combination of print and video materials available.
The following are some of the print materials available. We have provided links or you may contact your extension agent.
- Calibrating Ground Sprayers Using Shortcut Methods - a MSU Extension Publication
- Calibrating Pesticide Application Equipment – a MSU Extension Publication
- Calibrating Boom & Broadjet Sprayers – a MSU Extension Publication
- Calibrating Hand Sprayers – a MSU Extension Publication
