The number of herbicide-resistant weeds continues to increase in the United States. This is a huge concern for farmers, since weeds compete with crops for nutrients in the soil, potentially reducing crop yields. As a result, it’s important to know the best management practices to prevent or delay the development of more resistant biotypes. This handy trifold brochure will help Idaho producers navigate this challenging situation by providing some of the basics, including identifying the herbicide(s) to which nine common Idaho weeds are resistant.
