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.
Symptoms of bacterial diseases can be easily confused with those of fungal diseases in field crops. This article, from the Proceedings of the 2018 Nebraska Extension Crop Production Clinics, reviews some of the common mistakes made in the major field crops and reviews research on the impact of fungicide use after hail events in corn and soybean.
An article from the Proceedings of the 2018 Nebraska Extension Crop Production Clinics: Early season stand loss from wind or frost can be severe enough to require replanting of a sugarbeet crop. Three years of field trials at the Panhandle Research and Extension Center were conducted to determine just how much stands need to be reduced to justify replanting.
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.
