As noted during our May 11th Field Day presentation in Davis, during the 2016-17 season darkening/purpling glumes (as depicted in Image 1) were widely observed in common spring wheat both within the UC Regional testing program and by growers and crop consultants around the San Joaquin and Sacramento Valleys. In addition, these symptoms appeared to have a genetic link because particular wheat varieties consistently displayed symptoms in multiple locations, while others displayed none.
There are multiple potential causes for darkened glumes, some pathogenic and some physiological. Cassandra Swett, the UC Cooperative...

With the wet weather that has already marked this growing season and more rain in the forecast for parts of California, we have been keeping a close eye on disease symptoms. While we do not yet have definite conclusions to all of the symptomology we've observed, we believe it may be of interest and utility to share some of the disease notes and photos we've collected to date. We are grateful to the new UCCE Specialist in Plant Pathology, Dr. Cassandra Swett, who has been helping us to make sense of some of what we're been seeing in the field. Included below are some general notes followed by some more specific notes from Agronomy Advisors Nicholas Clark (San Joaquin...
