Stripe rust has significantly increased in all wheat-growing areas in Nebraska. It is recommended that wheat be treated with a fungicide to protect the flag leaf. If the incidence (percentage of flag leaves diseased) or severity (percentage of the flag leaf area diseased) is less than 50%, spraying a fungicide will significantly reduce yield loss due to stripe rust.
While native Americans had been eating dry beans for years, dry beans weren't commercially produced in the US until well into the 19th century. With a boost from Civil War military consumption in the 1860s, the industry grew and developed to become the global food supplier it is today. Nebraska ranks first in the nation in production of dry northern beans and fourth in overall dry bean production.
Based on the increase in dry pea acreage throughout western Nebraska, UNL conducted a comprehensive disease survey in 2015 to identify the most prevalent and important disease issues in Nebraska production. The primary problem consistently observed across the region was a bacterial blight complex caused by two distinct, but closely related pathogens: Pseudomonas syringae pv. pisi (Psp) and Pseudomonas syringae pv. syringae (Pss).
Does a reader need to be scientist — specifically, a plant pathologist — to appreciate a book about the history of discovering and treating plant diseases? Not if the reader appreciates history, science, and their broader lessons as conveyed through "The Bacterium of Many Colors" by Dr. Robert Harveson, UNL Plant Pathologist at the Panhandle Research and Extension Center.
Wheat disease surveys on April 8 and April 12-14 found stripe rust and leaf rust at trace to low levels in south central and southeast Nebraska and in the Panhandle. Given the locations of outbreaks in Banner County this spring are the same as when the disease was identified in seedlings last fall, the two rusts may have overwintered.
