This course provides a solid foundation for managing weeds.
Wherever you might live and work, there are many thousands of plants that could be a weed, and that fact limits just how deep we can take you with specific weeds. By looking at a good variety of common weeds and better understanding the range of weed control measures that are available; you can build a knowledge to underpin any weed problem you might encounter though. With what you learn here you should be able to make better informed decisions about how to tackle the control of weeds; no matter where, or what the context might be.
