Ec79-1206 Roses, Donald H. Steinegger, Frederick P. Baxendale, John E. Watkins, Amy Greving

University of Nebraska-Lincoln Extension: Historical Materials

Roses are one of the most versatile and exciting plant groups to use in landscape compositions. There are rose cultivars (varieties) adapted for almost any garden site or landscape purpose, including formal beds and perennial borders, arbors, trellises, hedges, ground covers, steep banks, edging, accent, specimen plants, and as patio or tub plants.

The most common rose types are hybrid teas, floribundas, grandifloras, and climbers. More people are becoming familiar with the so-called "old fashioned" or shrub roses. Many of these are well-adapted to Nebraska and to water-conserving landscapes.

G79-445 Soybean Variety Selection, Leroy V. Svec

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide has information on soybean characteristics that should be considered before selecting a variety to plant.

Soybean characteristics that need to be considered in making the selection of a variety to plant include maturity, yield potential, plant type, height, seed size, emergence score, lodging, shattering, and disease and insect resistance. Many years are required to develop a new variety from the time an initial cross of soybeans is made until the time seed is available on a widespread basis. The advance of a potential variety through the early generations may be accomplished with only a few seeds of the …

G76-292 Home Fruit Spray Schedules (Revised May 1986), Frederick P. Baxendale, Don Steinegger, David Wysong

University of Nebraska-Lincoln Extension: Historical Materials

Insects and diseases of home fruit plantings must be controlled to produce quality fruit. Home orchards must be sprayed several times during the growing season. Spraying only a few times will not produce acceptable results for most fruits.

This NebGuide discusses the types of sprays, sprayers, insecticides, insecticides and fungicides used to control insects.

G76-322 How To Handle Insect And Plant Specimens For Identification (Revised March 1985), Luanne Coziahr, Stephen D. Danielson, John Furrer, Don Steinegger

University of Nebraska-Lincoln Extension: Historical Materials

The Nebraska Cooperative Extension Service offers the public a pest/plant identification service. Under this service, insects, weeds, plant diseases, and horticultural plants are identified and, if appropriate, methods for their prevention or control are recommended. Diagnoses of plant problems and control recommendations will be more precise if specimens are handled according to the suggestions offered in this NebGuide.

G76-301 How To Tell Corn, Sorghum Maturity, J.D. Eastin, J.T. Hultquist, C.Y. Sullivan

University of Nebraska-Lincoln Extension: Historical Materials

Researchers have discovered a way to tell when corn and grain sorghum have stopped filling — when they are physiologically mature. A layer of cells near the point where the kernel is attached to the plant turns dark brown as the kernel nears maturity and, finally, black when the kernel is mature.

This NebGuide discusses how to read maturity in the layers of corn and sorghum.

G74-108 Wilts Of Cucurbits (Revised October 1994), James R. Steadman, David L. Keith, Laurie Hodges

University of Nebraska-Lincoln Extension: Historical Materials

Discussion covers the symptoms, disease cycles, and control measures for bacterial and Fusarium wilts of cucurbits, including cucumbers, cantaloupe, watermelons, squash, and pumpkins. Wilt caused by squash vine borer also is covered.

G73-12 Iris Borer Control, David L. Keith, Frederick P. Baxendale

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.

Rb56-180 False Smut Of Buffalograss, John L. Weihing

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. Ellis and B. M. Everhart in 1888. They gave only a brief description of the disease and named the causal fungus Cercospora seminalis. 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.

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 …

Ec23-120 Wheat In Nebraska, W.W. Burr, P.H. Stewart

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 …
