University of Nebraska-Lincoln Extension: Historical Materials

Scouting, prevention and control of the iris borer.

This insect is the most serious insect pest of iris in Nebraska and is found virtually everywhere in the state. Damage is characterized by dark, streaked, or watery areas and ragged edges on the developing leaves of iris in May and June and extensive destruction of the insides of the rhizomes in July and early August. Examination late in summer will reveal a large white to pinkish caterpillar from 1 1/2 to 2 inches long in the rhizome, usually accompanied by a foul-smelling soft rot.

Rb56-178 Streak Mosaic Of Wheat In Nebraska And Its Control, R. Staples, W.B. Allington

University of Nebraska-Lincoln Extension: Historical Materials

A mosaic of wheat was first observed in Nebraska by Peltier in 1922. Peltier found diseased plants in a large number of winter and spring wheat varieties at Lincoln, and in some instances, he successfully inoculated wheat and corn from the juice of infected plants. The temperatures under which Peltier maintained his inoculated plants are unknown and other criteria now employed to characterize the viruses were not utilized. It is probable, however, that he was working with what is now known as wheat streak mosaic virus.

This bulletin reports the results of studies on the epidemiology of wheat streak mosaic …

University of Nebraska-Lincoln Extension: Historical Materials

False smut of buffalograss, Buchloe dactyloides (Nutt.) Engelm., caused by Cercospora seminalis Ell. & Ev. is a disease that destroys the unfertilized ovary. The disease was first reported by J. B.

The origin of the term "false smut" is unknown to the author, but it so descriptively fits the general appearances of the disease that one readily understands its usage. The following studies were conducted from 1950 to 1954.

University of Nebraska-Lincoln Extension: Historical Materials

Wheat is one of the most important crops of the world. In total world tonnage it ranks third, being surpassed only by corn and potatoes. In th United States the tonnage is second only to corn, but wheat is far more important than corn as a human food.

Wheat is more important as a human food than any other rain crop. It is in itself almost a balanced food, and from earliest times has played an important part in the development of civilization. With the development of modern machinery wheat can now be produced without almost no hand work. On …
