Rainfall in spring and early summer 2017 was plentiful throughout western Nebraska, allowing good soil moisture for emerging crops, but also contributing to the development of plant diseases in multiple crops. This is an article from the Proceedings of the 2018 Nebraska Extension Crop Production Clinics.
Soil testing and a disease index developed at the university's Panhandle Research and Extension Center can help growers identify rhizoctonia risk levels of fields before they're planted to sugar beets.
Minor levels of striped rust have been confirmed in winter wheat from a field in Sheridan County north of Rushville. The infections occurred on only a few leaves and pustules were very small and difficult to see. Growers are encouraged to continue scouting wheat for disease; a fungicide application is not recommended at this time.
Four post-harvest sugar beet fungicide treatments are being evaluated as part of a new research study underway at the University of Nebraska Panhandle Research and Extension Center in Scottsbluff. The study, which is looking at whether fungicide treatments can improve winter storability of beets, is being conducted with support from Syngenta and Western Sugar Cooperative.
Reports of stripe rust in wheat continued throughout the Panhandle this week, particularly in Kimball and Banner counties. With additional sightings from central and southwest Nebraska, the disease appears to be widespread statewide this fall.
