Average germination rates of new crop soybean being tested by the Nebraska Crop Improvement Association are lower than in recent years. Growers are urged to check the germination rate for their soybean seed and adjust planting rate and use of fungicide treatments accordingly.
Though relatively small, UNL's Department of Plant Pathology has played a significant role in the discovery of many economically important plant diseases, including most recently, a new fungal pathogen causing Fusarium head blight of wheat. This article is from the 2019 Nebraska Crop Management Conference Proceedings.
In 2018 an array of weather conditions led to the development of several soybean diseases. Excessive early season moisture and heavy rains during the season resulted in many fields being impacted by Phytophthora root and stem rot. Frogeye leaf spot developed early in some areas and continues to build in the state with more fields being affected.
The 2018 crop season got off to a slow start with cold, wet conditions delaying planting in much of the state. Some seedling diseases developed in early planted corn, but with ample heat units the corn caught up quickly and most of the crop finished ahead of schedule. High relative humidity and rainfall drove the development of several leaf diseases mid-season.
This article, from the Proceedings of the 2019 Crop Production Clinics, addresses new and updated product labels for disease management, a report from the Plant and Pest Diagnostic Clinic, changes in the Department of Plant Pathology, and the initial US finding of Fusarium boothii on wheat in Nebraska.
Knowing the risk factors for stalk rot can help you evaluate those fields first and prioritize your harvest schedule accordingly. Submitting plant samples and determining which stalk rot is present can help you better prevent or manage it in future years.
