Ec99-1877 Damping Off, Root Rots, And Vascular Disorders Of Soybean, Loren J. Giesler

University of Nebraska-Lincoln Extension: Historical Materials

Soybeans are grown on nearly 4 million acres in Nebraska and are threatened by several diseases, soil-borne fungal diseases being the most common (for growers in the Midwest). Early season damping off and root rots often are followed by premature death, which in many instances is attributed to fungal infections earlier in the growing season causing root and cortical rots and vascular disorders.

This extension circular discusses these diseases, their symptoms and control.

Nf99-397 Gray Leaf Spot Of Perennial Ryegrass In Nebraska, John E. Watkins

University of Nebraska-Lincoln Extension: Historical Materials

Gray leaf spot, caused by the fungus Pyricularia grisea, was reported in the early 1970s to be a damaging disease of annual ryegrass grown for forage in the southeastern United States. Forage yield losses were so severe that the disease was named ryegrass blast.

This NebFact discusses the diagnosis, future occurrences, and management of gray leaf spot in Nebraska and surrounding states.
