NRBB 1032 - Management of Invasive and Noxious Weeds

  • NonCredit
View available sections

Weeds affect us all, they steal moisture and nutrients from desirable plants, shade out older plants, decrease nutritional value of forage, and some are toxic to livestock or humans. Weed infestations can decrease forage yields and lower the value of pastures. In this course you will learn to identify, prevent, and the manage weeds on your property. Proper weed management is very dependent upon several factors including weed life cycles and timing of treatments. You will learn integrated pest management (IPM) principles in which mechanical, biological, and chemical controls are discussed. Not all weeds are managed the same way. Utilizing the appropriate control method will ensure reduced costs and weed impacts over time. This course explores organic control options, as well as chemical controls and highlights real-life examples of how specific weed infestations were successfully managed.
