New Video on Integrated Weed Management

A new video titled, “Integrated Weed Management with Ian C. Burke” is now available on the Wheat and Small Grains website.

Integrated weed management (IWM) strategies are required for effective long-term management of weeds in the agroecosystem. Knowledge of weed biology is critical for successful long-term IWM, as is integration of multiple methods of weed management. Methods of weed management include preventative, mechanical, cultural, and chemical inputs. Weed managers should develop a management plan that incorporates knowledge of weed biology, consideration of inputs, and effective method evaluation. A good competitive crop will always be the best weed management practice, and a sequence of successful crops in rotation is critical for managing weeds in the inland Pacific Northwest (PNW).

Chapter 9 (pdf) of the Regional Approaches to Climate Change:

  • An integrated weed management approach depends on knowledge and application of ecological principles, an understanding of plant interference and weed-crop competition, and the appropriate use of preventative, cultural, mechanical, and chemical weed management strategies.
  • Herbicides are an effective tool for managing weeds in inland PNW grain production, but they should be used judiciously and in combination with other strategies in order to implement a weed management program that is effective, economical, and prevents the development or spread of herbicide-resistant weed biotypes.

Produced as part of the Regional Approaches to Climate Change project, the IWM video above and the corresponding Advances in Dryland Farming in the Inland Pacific Northwest chapter give a general framework for farmers to follow when analyzing or developing an integrated weed management system, including important principles.
