The Morphometrics Of Xiphinema Americanum Sensu Lato In California, John A. Griesbach, Armand R. Maggenti

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Ten populations of Xiphinema americanum sensu lato (S. l.)from California and two from the eastern United States were studied in a morphometric comparison. Morphometrics were generated by descriptive statistics and a stepwise discriminant analysis (SDA) from nine California field populations, and voucher specimens from a previous California vector study (Hoy, Mircetich & Lownsbery, 1984); identifed as X. californicum. AIso included were greenhouse populations of X. americanum Cobb, 1913 sensu stricto (s. s.) from New York (N.Y.) and X. rivesi Dalmasso, 1969 from Pennsylvania (Pa). SDA canonical plots of individual specimens showed the X. rivesi population …

Cuticular Ridge Pattern In Ostertagia Gruehneri And Ostertagia Arctica (Nematoda: Trichostrongyloidea) From Caribou, Rangifer Tarandus, J. Ralph Lichtenfels, P. A. Pilitt, M. Fruetel

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Two species of medium stomach worms are common parasites of the caribou, Rangifer tarandus. The two species, Ostertagia gruehneri Skrjabin, 1929, and O. arctica Mitzkewitzsch, 1929, differ so markedly in morphology of the spicules and genital cone that many nematode systematists place them in different genera. Recent studies of similar pairs of species parasitic in other ruminants have provided evidence that such pairs of species may be morphotypes of one species. The two species from caribou are redescribed with emphasis on the pattern of surface cuticular ridges and the structure of the esophagus, characters considered useful for distinguishing species …

G90-990 Explosion Venting And Suppression Of Bucket Elevator Legs, David D. Jones

University of Nebraska-Lincoln Extension: Historical Materials

Explosion vents and explosion suppression devices limit the danger and damage associated with grain dust explosions. This NebGuide discusses these devices and design guidelines for application on bucket elevator legs.

The bucket elevator leg has been identified as a major source of grain dust explosions. As a bucket elevator leg conveys grain, the elements necessary for a grain dust explosion are possible. Fuel (grain dust in suspension above the minimum explosive concentration), oxygen and confinement are inherent inside a functioning bucket elevator leg. Introduction of an ignition source will initiate a grain dust explosion.

G90-974 The Beaf Leaf Beetle In Soybeans (Revised September 1994), Thomas E. Hunt, J. F. Witkowski, Robert J. Wright, Keith J. Jarvi

University of Nebraska-Lincoln Extension: Historical Materials

The identification and life cycle of the bean leaf beetle are discussed along with scouting techniques, economic thresholds, and cultural control tactics.

The bean leaf beetle is a common insect found in Nebraska soybean fields. The insect also feeds on peas, snap beans, and dry beans. Although present in alfalfa and sweet clover in the early spring before soybean emerges, the insect is not known to damage either legume.

Use integrated pest management (IPM) when planning how to reduce bean leaf beetle damage. Integrated pest management is a sustainable approach to managing pests by combining biological, cultural, physical, and chemical …

G90-988 A Process For Building Coalitions, Georgia L. Stevens

University of Nebraska-Lincoln Extension: Historical Materials

What should you consider in building coalitions? This NebGuide offers guidelines.

What is a Coalition?

1. A coalition is a group of organizations and individuals working together for a common purpose. There are two types of coalitions:

2. "One issue" or event coalitions only have to agree on one particular issue. The coalition is dissolved when the issue has been solved or the event has been coordinated.

"Multi issues" coalitions have related issues, such as nutrition and health, child care needs, elderly health care, or the environment. This more permanent type of coalition recognizes the value of mobilizing together for …

G90-1002 Child Labor Laws For Agriculture, Raymond Massey

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide details special considerations for employing persons 16 years of age and younger.

The employment of minors became regulated by the Fair Labor Standards Act of 1938. Amendments to this Act and additional Nebraska laws have further regulated child labor use.

Agriculture is given special provisions regarding child labor. Specific regulations pertaining to age, working hours and hazardous jobs have been written to assure that minors are not employed nor endangered while working in agricultural jobs.

The child labor provisions mentioned in this NebGuide apply to the agricultural employment of all non-family minors, migrant as well as local resident …

G90-964 How Soil Holds Water, Norman L. Klocke, Gary W. Hergert

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes the physical characteristics that influence how soil holds water.

Dryland and irrigationd agriculture depend on the management of two basic natural resources, soil and water. Soil is the supporting structure of plant life and water is essential to sustain plant life. The wise use of these resources requires a basic understanding of soil and water as well as the crop.

The available water capacity and characteristics of soils are critical to water management planning for irrigationd and dryland crops. The management decisions of what crops to plant, plant populations, when to irrigation, how much to irrigation, when …

G90-1001 Spray Drift Of Pesticides, Larry D. Schulze, Robert Grisso, Robert Stougaard

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses conditions that cause particle drift, and methods private and commercial applicators may employ to reduce drift potential from pesticide spray applications.

Spray drift of pesticides away from the target is an important and costly problem facing both commercial and private applicators. Drift causes many problems including:

1. damage to susceptible off target sites,

2. a lower rate than intended which can reduce the effectiveness of the pesticide, wasting pesticide and money, and

3. environmental contamination, such as water pollution and illegal pesticide residues.

Drift occurs by two methods; vapor drift and particle drift. This NebGuide focuses mainly …

Evaluation Of Seeding Rates Of Au Triumph And Endophyte-Infected Kentucky 31 Tall Fescue, Jeffrey F. Pedersen, D. M. Ball

Department of Agronomy and Horticulture: Faculty Publications

Increased difficulty in stand establishment of tall fescue (Festuca arundinacea Schreb.) has been reported by producers since the introduction of endophyte (Acremonium coenophialum Morgan Jones and Gams)-free tall fescue seed into the market place. This has encouraged the use of higher seeding rates for endophyte-free tall fescue without scientific basis. The objective of this study was to determine whether ‘AU Triumph’, and endophyte-free cultivar, and endophyte-infected ‘Kentucky 31’ differ in minimum seeding rates for successful establishment. Experiments were established at two locations in each of two years, using a randomized complete block with four replications. Soils at the two locations …

Heritability Of Root Characteristics Affecting Mineral Uptake In Tall Fescue, J. H. Edwards, Jeffrey F. Pedersen, R. C. Kingery

Department of Agronomy and Horticulture: Faculty Publications

Modification of plant roots can potentially increase the area. of adaptation of tall fescue (Festuca arundinacea Schreb.). Limited information is available on the heritability of root diameter and root volume in tall fescue. A greenhouse experiment was conducted with'50 random 'Kentucky 31' (Ky-31) tall fescue parents and their progeny grown in aerated nutrient solution during four separate time intervals. Measurements of root volume, root diameter, shoot Mg concentration, and shoot K/(Mg + Ca) ratio were made six weeks after clonal material was transplanted in nutrient solution. Heritability estimates for root volume, root diameter, shoot Mg concentration, and shoot K/(Mg …

A Review Of The Agronomic Characteristics Of Endophyte-Free And Endophyte-Infected Tall Fescue, Jeffrey F. Pedersen, G. D. Lacefield, D. M. Ball

Department of Agronomy and Horticulture: Faculty Publications

Agronomic differences between endophyte- (Acremonium coenophialum Morgan Jones and Gams) free and endophyte-infected tall fescue (Festuca arundinacea Schreb.) exist, and should be considered when implementing a management strategy. Although dry matter yield of tall fescue does not generally appear to be influenced by endophyte infection status, endophyte infection has been shown to improve seedling performance and survival, is associated with insect and nematode resistance, drought resistance, improved nitrogen assimilation, and higher seed set. Considering all biologically valuable characters of the endophyte-tall fescue relationship, survival of endophyte-infected tall fescue is probably better than that of endophyte-free tall fescue, especially in drought- …

Adsorption Of The Herbicides Diuron, Terbacil, And Simazine To Blueberry Mulches, Laurie Hodges, Ronald E. Talbert

Department of Agronomy and Horticulture: Faculty Publications

Samples of soil, mulch, and the soil/mulch interface zone were collected from commercial highbush blueberry (Vaccinium corymbosum L.) fields typical in their use of mulch under Arkansas conditions. Mulches included 1-year-old hardwood sawdust, 5-year-old hardwood sawdust, and 1-year-old pine needle mulch. Herbicide adsorption (Kd values) of the samples was determined for diuron, terbacil, and simazine. The soils, mulches, and interfaces adsorbed nearly 10 times as much diuron and more than twice as much simazine as terbacil. Adsorption of the herbicides was three to five times greater to the mulches than to the soils. Adsorption was significantly correlated with the …

Stability Of Iaa And Iba In Nutrient Medium To Several Tissue Culture Procedures, Scott Nissen, Ellen Sutter

Department of Agronomy and Horticulture: Faculty Publications

The relative stabilities of IAA and IBA under various tissue culture procedures were determined. IBA was significantly more stable than IAA to autoclaving. IBA was also found to be more stable than IAA in liquid Murashige and Skoog medium (MS) under growth chamber conditions. The stabilities of IBA and IAA were similar in agar-solidified MS. Light provided by cool-white fluorescent bulbs promoted degradation of IAA and IBA in both liquid and agar media. Activated charcoal in concentrations as high as 5% was found to adsorb more than 97% of IAA and IBA in liquid MS. These results have important implications …

Efficacy Of A Cell Extract From Actinobacillus (Haemophilus) Pleuropneumoniae Serotype 1 Against Disease In Swine, P. J. Fedorka-Cray, M.J. Huether, D.L. Stine, G. A. Anderson

School of Veterinary and Biomedical Sciences: Faculty Publications

We partially characterized a cell extract (CE) from Actinobacillus pleuropneumoniae serotype 1 and used the CE to test the efficacy of secreted proteins against disease. Secreted products from 4-h culture supernatants were precipitated with 20% polyethylene glycol. Analysis of the CE indicated the presence of protein, endotoxin, and carbohydrate. Hemolytic activity to bovine erythrocytes and cytotoxic activity to porcine mononuclear leukocytes was also demonstrated. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis of the CE from a 4-h culture showed a major band at 110 kilodaltons (kDa), while a CE of a 26-h culture indicated the presence of a number of additional …

Construction Of An Opal Suppressor By Oligonucleotide-Directed Mutagenesis Of A Saccharomyces Cerevisiae Trna Gene, Audrey L. Atkin, K. L. Roy, J. B. Bell

School of Biological Sciences: Faculty Publications

In vitro mutagenesis was used to create putative opal suppressor alleles of a tRNA^Trp gene of Saccharomyces cerevisiae. The construct with the requisite anticodon change did not result in an active suppressor, whereas when a second change was introduced into the portion of the gene encoding the intron, an active and specific opal suppressor was produced. We propose that the secondary structure of transcripts from the first mutant may prevent efficient pre-tRNA processing, whereas normal processing occurs with the double mutant.
