Nf97-328 A Guide To Grasshopper Control In Cropland (Revised May 2004), Gary L. Hein, John B. Campbell Jan 1997

Nf97-328 A Guide To Grasshopper Control In Cropland (Revised May 2004), Gary L. Hein, John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

Grasshoppers have been a major concern to farmers and ranchers since Nebraska was first settled. The potential for devastation, while still serious, is not as great as it was 100 years ago because many of the prime grasshopper breeding areas along the eastern slopes of the Rocky Mountains are now under tillage. Statewide, grasshopper populations fluctuate in cycles with large numbers occurring for two to four years, followed by moderate numbers for several years.

This NebFact discusses grasshopper damage to cropland, how to determine when control is required and methods of control.

G94-1220 Controlling Ticks, John B. Campbell, Gustave D. Thomas Jan 1994

G94-1220 Controlling Ticks, John B. Campbell, Gustave D. Thomas

University of Nebraska-Lincoln Extension: Historical Materials

Identification and control of ticks common to Nebraska.

Ticks are members of the same phylum (Arthropoda) of the animal kingdom as insects, but are in a different class (Arachnida). The main difference is the body of a tick is composed of only two sections while insect bodies have three sections.

There are over 800 species of ticks, 100 of which are important to man and animals because of economic losses or disease transmission. Fortunately in the United States, only about 12 species are economically important because they transmit disease organisms (viral, bacterial, protozoan, and rickettsial) or cause economic losses to …


Ec94-138 Pigweed Identification: A Pictorial Guide To The Common Pigweeds Of The Great Plains, M.J. Horak, D.E. Peterson, D.J. Chessman, L.M. Wax Jan 1994

Ec94-138 Pigweed Identification: A Pictorial Guide To The Common Pigweeds Of The Great Plains, M.J. Horak, D.E. Peterson, D.J. Chessman, L.M. Wax

University of Nebraska-Lincoln Extension: Historical Materials

Several pigweed species are found in the Great Plains. Pigweeds commonly reduce crop yields and interfere with harvest. One means of controlling these weeds is through the use of herbicides. Recent research indicates that some pigweed species respond differently to various herbicides; therefore, proper identification is needed for good control.

This extension contains a generalized distribution map; photographs of seeds, seedling, and mature plants; and text describing other identifying features for each pigweed species. The species are grouped with others that have similar shape and form. The pigweed species listed in this publication are: redroot pigweed, smooth pigweed, Powell amaranth, …


Ec91-1767 Windbreaks For Rural Living, James R. Brandle, Teresa K. Boes, Bruce Wight Jan 1991

Ec91-1767 Windbreaks For Rural Living, James R. Brandle, Teresa K. Boes, Bruce Wight

University of Nebraska-Lincoln Extension: Historical Materials

In many parts of the United States, the constant force of the wind exaggerates daily weather conditions and can make living in these areas seem unbearable. A well-designed windbreak around the home, ranch, or farmstead slows the wind and improves the overall environment. Farm and ranch windbreaks conserve energy, provide snow control, improve working and recreational environments, enhance wildlife populations, provide visual screening and dust control, and increase the production of various wood and food products.

Ranch and farmstead windbreaks provide the greatest benefits in areas with high winds, large amounts of snow, extreme temperature fluctuations, or minimal natural forest …


Ec91-1771 Windbreaks And Wildlife, Ron J. Johnson, James R. Brandle, Mary M. Beck Jan 1991

Ec91-1771 Windbreaks And Wildlife, Ron J. Johnson, James R. Brandle, Mary M. Beck

University of Nebraska-Lincoln Extension: Historical Materials

Windbreaks can support wildlife that add beauty and pleasure to our lives. They also sustain birds that eat insect pests, improve hunting opportunities, and provide a focal point for family outdoor activities. The world around us would be less appealing without the stimulation--the color, sounds, tracks, and mystery--of wild creatures; windbreaks help wildlife and in some areas are essential to survival of the wildlife we enjoy. You can add wildlife benefits to windbreak plantings whether your main goal is to shelter crops, livestock, roads, or a home or farmstead. This publication provides an overview of windbreaks and wildlife, and gives …


G91-1029 Preventing Fruiting In Woody Plants, Don Steinegger Jan 1991

G91-1029 Preventing Fruiting In Woody Plants, Don Steinegger

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide covers what to use to prevent fruiting or remove fruit from ornamental landscape trees and shrubs.

The ideal shrub or tree for a home landscape is one that is aesthetically pleasing, architecturally suitable, and adapted to its site. Aesthetically, plants with season-long foliage and fall color are desirable. The landscape value of these plants increase if they also produce flowers and fruits.

Despite the increased value of a flowering plant, some people consider spent flowers and fruits undesirable litter, especially when they fall on driveways and sidewalks. Also, plants producing edible fruit and serving as landscape plants require …


G91-1016 Cool Season Turfgrass For Nebraska, Terrance P. Riordan, Garald L. Horse Jan 1991

G91-1016 Cool Season Turfgrass For Nebraska, Terrance P. Riordan, Garald L. Horse

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes 12 species of cool season turfgrasses and the recommended cultivars which are best adapted to Nebraska.

Cool season turfgrasses have an optimum soil temperature of 60-70°F. They grow most actively in the spring and fall, with growth slowing in summer. More than 20 cool season species are used for turf throughout the world.

Nebraska's climate is moderately conducive to cool season turfgrass species growth. The 12 species best adapted to Nebraska and some of the recommended cultivars are described.


G88-873 Growing Shrubs From Seed, Richard J. Lodes, Mike Kuhns Jan 1988

G88-873 Growing Shrubs From Seed, Richard J. Lodes, Mike Kuhns

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide is about gathering and growing seeds for shrubs.

Growing shrubs from seed is educational and fun. Many shrub species are not available commercially, so gathering seed and growing your own plants may be the only way to get them. Interesting or unusual shrubs from a neighbor's yard or from the wild can be propagated from seed. Shrubs started from seed also may be less expensive than commercially produced seedlings.


G86-807 Where Do Weeds Come From?, John Furrer, Robert G. Wilson Jan 1986

G86-807 Where Do Weeds Come From?, John Furrer, Robert G. Wilson

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses weed seed entry and loss from the soil, and provides examples of the density and diversity of the soil weed seed population. Weed Seed in the Soil Most weeds owe their beginning to seed in the soil. The soil acts as a seed storage reservoir and a growth medium for weedy plants. The kind or species and numbers of seed in the soil is closely linked to the cropping history of the land. Grasslands contain seed associated with grassland plants and cropland contains seed affiliated with weeds growing on cultivated land. Grasslands that have been cultivated and …


G84-702 Root And Soil Analayses For Nematodes In Corn, David S. Wysong, Eric D. Kerr Jan 1984

G84-702 Root And Soil Analayses For Nematodes In Corn, David S. Wysong, Eric D. Kerr

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes how to interpret laboratory results of samples submitted for nematode analysis and discusses ten species that are potentially damaging to corn.

Several kinds of plant parasitic nematodes (small, soil-inhabiting roundworms) are associated with root injury, poor plant color, stunted growth, and reduced grain yields in field corn. Symptoms caused by these pests are often confused with root rot diseases, nutritional deficiencies or climatic stresses. Special laboratory analyses are, therefore, necessary to determine if nematodes are the primary cause of reduced corn performance. Since corn growers may be unfamiliar with nematode diseases, the following discussion of laboratory reports …


G76-314 Native Wood Fence Posts (Revised February 1990), Thomas L. Schmidt, Michael R. Kuhns Jan 1976

G76-314 Native Wood Fence Posts (Revised February 1990), Thomas L. Schmidt, Michael R. Kuhns

University of Nebraska-Lincoln Extension: Historical Materials

This guide evaluates native Nebraska tree species for use as wooden fence posts.

Fencing is a major part of most farming and ranching operations. Fences are costly and require regular repair and maintenance. Wood fence posts cut from native Nebraska trees can be less expensive than steel posts or wood posts imported from other states. When deciding whether to use native wood fence posts, consider durability, availability and ease of handling.
