Four herbicides and combinations of these herbicides with MCPA were evaluated for the control of Littleseed canarygrass in durum wheat. The currently registered herbicides, Achieve and Puma (not registered in Arizona) produced control levels of 80 to 95 percent with good crop safety. The new herbicides being developed, Osprey and Olympus produced higher and more consistent levels of control of 95 to 99 percent but caused slight to moderate crop injury. Combinations of Achieve and Puma with MCPA, a broadleaf herbicide, resulted in decreased control. When Osprey was tank mixed with MCPA, crop injury was increased.
