In this Extension bulletin, we describe the ecology of jointed goatgrass at various stages of its life cycle, and then relate these characteristics to the effectiveness of cultural practices used for managing jointed goatgrass.
Jointed goatgrass and wheat have a close genetic relationship and share many traits. Understanding the genetic relationship between wheat
and jointed goatgrass will help with the development of management strategies. Current herbicide-resistant wheat technology will provide
producers with a tool to control jointed goatgrass in the crop.
In the Pacific Northwest (PNW), wild oat has become a notable weed pest of small grain and rotational crops, including pulse crops, potato, sugar beet, and oilseed crops. It has infested more than 3 million acres of cropland in Idaho, costing small grain growers in the state alone more than 9 million dollars annually in control costs. Feeding its spread is the fact that it has developed resistance to several herbicides. This PNW provides all the basics you need to mount a defense against the stubborn grass, including its identification, crop impacts, and management strategies. A handy table also lists the brand-name herbicides to which the wild oat has developed resistance, upping the odds on your control efforts.
