Weeds are the bane of many farmers’ existence in eastern Washington. It seems we are in a constant battle to keep weeds under control. As part of that effort, WSU weed scientists, Drew Lyon and Ian Burke, manage numerous field studies to evaluate new herbicides, and new uses of older herbicides, to manage weeds of concern to dryland farmers in eastern Washington. These studies are summarized in the annual WSU Weed Control Report.
The latest of these reports, the 2017 WSU Weed Control Report, is now available on the Wheat and Small Grains website. The report summarizes 31 field studies conducted across eastern Washington in winter wheat (13 studies), spring wheat (3 studies), summer fallow (5 studies), chickpea (5 studies), canola (1 study), and grassland (3 studies).
Weeds investigated include:
Annual reports back to 2013 are also available.
Some of the pesticides discussed in the report were tested under an experimental use permit granted by WSDA. Application of a pesticide to a crop or site that is not on the label is a violation of pesticide law and may subject the applicator to civil penalties up to $7,500. In addition, such an application may also result in illegal residues that could subject the crop to seizure or embargo action by WSDA and/or the U.S. Food and Drug Administration. It is your responsibility to check the label before using the product to ensure lawful use and obtain all necessary permits in advance.
