Crop farmers, livestock owners, and landowners often have questions about controlling weeds in forages. Because most forage weeds are perennials, they tend to slowly multiply over time and not be noticeable until they are difficult to control. Whether weeds are problems in pastures or hay production systems, you must consider certain factors in order to successfully manage them.

This asynchronous, self-paced course course discusses how cultural practices, such as grazing, mowing, and soil fertility can affect weed forages. Using short text and videos, this course teaches you the importance of integrated weed management, helps you identify weeds, and addresses chemical and physical management options. More specifically, learn about some common herbicides, what weeds they control, and the potential costs of these applications.

By successfully completing this course, including passing a final quiz, you can earn 1 Pennsylvania Department of Agriculture (PDA) Category 1 or Category 18 credit, as well as a certificate of completion.

(Note: it may take 2 to 4 week for recertification credits to be reported to and verified by PDA.)
