We had a great turn out for our plot tour on Thursday. Many of our customers braved the chance of rain to come check out our plots at the research farm on Hwy 34. We also had Chris Mundt, OSU Plant Pathologist, and Andy Hulting, OSU Extension Weed Specialist, as well as Dave Lockwood from Corvallis Feed and Seed.

The warmer-than-usual weather in January and February and the cooler-than-usual weather in March, April, and May coupled with the early infection of a new race of stripe rust has created the perfect storm for disease advancement. Chris Mundt gave further evidence of this by saying that this is the first time in 22 years that he has observed any significant stripe rust on the Stephens variety of winter wheat. Stripe rust in winter wheat and the wet weather that is prolonging the problem even made a featured story on Fox12 Portland news last night.
OSU still has confidence that Goetze is a good variety for us. With stripe rust being driven by weather it's a tough year to make any serious conclusions other than the fact that it's a tough year. We can't give up on Goetze yet. On a drier year we want the high yield potential Goetze has to offer.
There have been several of these plot tours over the last week or so, including the Hyslop Farm tour and a couple North Valley tours. The take home message on the stripe rust has been that the need for fungicides is now. In other words, if you are going to retreat any fields you need to get it done now or forget about it. We have to protect the flag leaf to get seed fill and prevent shriveled kernels and low bushel weights. Once we lose green leaf surface area to disease the best we can do is stop it, we can't make it green again. Most of the fungicide labels have a cutoff at flowering which is very quickly approaching. As long as the plants continue to stay wet, both stripe rust and septoria will be able to advance at will. Talk with your CPS fieldman about your options.
