Weed management handbook

Asked February 17, 2019, 8:04 PM EST

The handbook is primarily about herbicide use on weeds, correct? Is there a resource describing non-chemical methodology? Thanks

Thank you for your question. Are you referring to the OSU PNW Weed Management Handbook? It typically has cultural, mechanical and biological controls (if any) in lieu of chemicals. This is called Integrated Pest Management. If available, the list of chemical treatments also indicates which are organic [O] and which are available to homeowners [H], as opposed to being available only to licensed chemical applicators. Unlike insects, pathogens (fungi, bacteria, etc.) and wildlife, there are typically no ‘easy’ solutions short of chemicals to eradicate weeds. They will inherit the earth. But you can search for ‘solutions’ in addition to chemicals by doing a web search such as ‘“weed” IPM site:edu’, substituting ‘your’ weed at the beginning. That will get you to research-based information on the integrated management strategies currently known. Hope this is helpful. Good luck!
