Mike Flowers, Oregon State University Cereal Specialist, is offering the following observations at our CBARC and Ruggs OWEYT trials.
It appears that HTAP is finally kicking in. On many varieties it was very difficult to find active rust. Of course there were exceptions like Tubbs 06, Xerpha, and AP Legacy.
Also several varieties are showing hypersensitive reactions like OR2040726 (little to no active rust, but lots of yellow).
Growers in the area seem to have stayed on top of the rust and kept it under control (there are exceptions). Hopefully this will keep the rust load down for the remainder of the year and next fall.
The crop is late. Neither site was headed yet, which means we are 10-14 days behind.
There will be plenty of moisture for early seeding as we continue to get rain. This sets us up for fall stripe rust infections and may mean we will see another bad rust year. So variety selection this fall will be very important.
Be sure to attend one of the OSU Station Field Days near you next week to get more information on this topic and other research farming cereals in the Pacific Northwest.
