Tolerance of winter wheat to Pursuit and Osprey
Farm and Ranch July 2, 2009 Some farmers says they can see an impact on their winter wheat planted into pea ground to which Pursuit was applied. But are winter wheat yields being impacted? Research on that question is being conducted in Moscow, Idaho, Pullman, Washington and Pendleton, Oregon. The study is evaluating the response of winter wheat varieties seeded into fall applied Pursuit followed by spring applied Osprey under adverse environmental conditions such as freezing nights and large temperature fluctuations. Wheat varieties in the project are Brundage 96, ORCF 102 and Tubbs 06. Tracy Rauch, a research support scientist at the University of Idaho, describes what‘s being seen in Moscow plots. Rauch: “We are in the second year of this study and so far what we have seen even at a 1X rate, in other words, the three ounce rate that would be put on the legumes, it hasn‘t caused any injury the next year to the winter wheat crops.” Rauch says that doesn’t mean there won’t be some visual injury. Rauch: “Yeah, we might see some visual injury but when it comes down to actual yields, the varieties yield differently among themselves, but there is no effect of the Pursuit.” Another study looked at Osprey applied under adverse environmental conditions alone or in combination with Bronate Advanced and compared to Bronate Advanced alone and a check. Wheat grain yield did not differ among treatments. Varieties tested were Boundary, Brundage 96, Chukar, Eddy, Madsen and ORCF 102.
