Fundamental Principles Of Plant Pathology For Agricultural Producers, Paul C. Vincelli

Agriculture and Natural Resources Publications

All crop plants produced in Kentucky have the potential to become diseased under certain conditions. Diseases of crops can affect yield and/or quality of the harvested commodity. This can impact profitability and increase the risks of farming.

A plant is diseased when it is affected by some agent that interferes with its normal development. Some disorders are caused by noninfectious factors, such as temperature extremes or nutrient deficiencies. However, this publication focuses on diseases caused by infectious microorganisms.

Diseased plants exhibit a variety of symptoms. These can include stunting, yellowing, wilting, twisting, reddening, browning, blighting, root rot, fruit rot, …

Harvesting Hay For High Yield And Quality — More On Bale Ventilators And Other Harvest Aids, Michael Collins

Kentucky Alfalfa and Stored Forage Conference

In some areas of the country, producers store a substantial portion of their forage for winter feeding as silage or haylage. However, hay remains the most popular storage method for forage. Hay stores well for long periods and is better suited to cash sale and transportation than silage. Mechanical conditioning, which gained acceptance during the 1950's is probably still the greatest single change in hay harvesting and storage technology during this century. However, a number of other noteworthy changes and innovations have occurred in recent years which have helped to reduce the extent of losses during hay harvesting and storage. …

Wetlands: Mechanisms For Treating Acid Mine Drainage, David C. Ditsch, Anastasios D. Karathanasis

Agronomy Notes

A great deal of attention has been given to wetlands in recent years. Research suggests that natural and/or constructed wetlands may play a valuable role in flood flow moderation, sediment retention and stabilization, and waste water treatment while providing habitat for game and nongame wildlife. Only within the last 10 years have wetlands received serious attention in the treatment of acid mine drainage (AMD).

Field Test Of "Farm For Profit®" Burley Tobacco Production Program, Kenneth L. Wells, Mark Reese

Soil Science News and Views

Considerable interest exists among local farmers in Scott County, Kentucky, about a "Farm For Profit^®" tobacco production program being advocated by the representative of a product supplier as a means of improving burley tobacco production. Because of this interest, we conducted a field test of this program in 1993. The objective was to compare yield results from this "program" with those from two, more conventional practices.

Water Quality And Fecal Indicator Bacteria, Mark S. Coyne

Soil Science News and Views

How can you tell if water is fit to drink? Color and taste aren't reliable guides for water safety. Clear water can be contaminated with chemicals or microorganisms the senses can't detect. One of the principle qualities of potable (drinkable) water is its freedom from microbial contaminants. This article will describe some criteria and methods that are used to determine the microbial quality of water.

The Fecal Coliform/Fecal Streptococci Ratio (Fc/Fs) And Water Quality In The Bluegrass Region Of Kentucky, Mark S. Coyne, J. M. Howell

Soil Science News and Views

In the mid 70' s, someone noticed that the ratio of two indicator bacteria in fecal wastes - fecal coliforms (FC) and fecal streptococci (FS) - was characteristic of particular animal wastes. In human wastes, the fecal coliform/fecal streptococci ratio (FC/FS ratio) was greater than 4. In domesticated animals, like cattle, the ratio was between 0.1 and 4.0. In wild animals, the ratio was less than 0.1. Since that time, many attempts have been made to use the ratio to determine the source of fecal bacteria in contaminated ground water.

Impact Of Riparian Grass Filter Strips On Surface-Water Quality, Alex W. Fogle, Daniel I. Carey, Billy J. Barfield, Robert L. Blevins, Vasilios P. Evangelou, Cora E. Madison, Shreeram P. Inamdar

Information Circular--KGS

The effectiveness of natural riparian grass filter strips in removing sediment and agricultural chemicals from surface runoff was studied using no-tillage and conventional-tillage erosion plots. Runoff from the tillage plots was directed onto 4.57, 9.14, and 13.72 m (15, 30, and 45 ft.) length filter strips, where the inflow and outflow concentrations and sediment size distributions were measured. Trapping efficiencies for sediment and agricultural chemicals typically ranged near or above 90 percent, mainly because of high infiltration rates. The filters also significantly reduced peak discharge concentrations, which reduced the impact of sediment and agricultural chemicals on receiving surface waters.

Frequency Of Mug Negative Escherichia Coli In Kentucky Groundwater Samples, Mark S. Coyne, J. C. Shuler

Plant and Soil Sciences Faculty Publications

MUG negative Escherichia coli are a small fraction (2.5%) of the total E. coli in Kentucky groundwater samples. It is unlikely that they alone will cause a significant potential to underestimate fecal contamination using MUG as the primary criterion for that assessment. An unresolved question is how effectively MUG-based, defined-substrate tests address false negative water samples containing MUG positive E. coli.

Enhanced Immunogenicity Of Protein-Dextran Conjugates: I. Rapid Stimulation Of Enhanced Antibody Responses To Poorly Immunogenic Molecules, Andrew Lees, Fred Finkelman, John K. Inman, Kim Witherspoon, Penny Johnson, Jasiri Kennedy, James J. Mond

Microbiology, Immunology, and Molecular Genetics Faculty Publications

In view of our observation that anti-immunoglobulin antibody conjugated to high-molecular-weight dextran stimulates high levels of B-cell activation (Brunswick et al. J. Immunol . 1989, 143, 1239), we coupled T cell-dependent antigens to dextran. When mice were immunized, in the absence of adjuvant, with a BSA-dextran conjugate (BSA-dex), a persistent, high-titre anti-BSA IgG1 response was induced. Titres were dose-dependent and seen with as little as 10 I~g of conjugated protein. Anti-BSA titres were detected as early as day 7, usually peaked at about day 14 and persisted for at least 4 weeks. Anti-hapten antibodies were also elicited in mice that …

Survey Of The Impacts Of Environmental Regulations On State Highway Operations, Theodore Hopwood Ii, Christopher M. Oberst

Kentucky Transportation Center Research Report

In recent years, the transportation industry in Kentucky as represented by Kentuckians for Better Transportation (KBT) and the Kentucky Transportation Cabinet (KyTC), have expressed concern over the growing impact of environmental regulations upon transportation activities in the state. The imposition of environmental regulations has resulted in higher costs for new construction and maintenance on roads, project delays, scheduling and financing difficulties, and the creation of additional transportation agency bureaucracy to address environmental regulation mandates. In Kentucky, the impacts of those regulations have not been thoroughly assessed nor have the attendant costs been measured. Coinciding with that lack of information is …

Generation And Legal Regulation Of Odors Form Animal Manures, J. L. Taraba, R. M. Williams

Agricultural Engineering Extension Updates

The present trend of animal and dairy product producers is toward total confinement facilities and larger animal herds. Generally the rewards to the producer for these practices are higher economic returns which result from higher feeding efficiencies and better quality products. However, total confinement is not without problems that were previously not present or were minimal in nature when animals were maintained in fields. Confinement facilities have a greater impact on environmental quality of both water and air. Presently, one of the major problems facing animal and dairy product producers is odor production. The greatest number of complaints concerning environmental …

Quality Of Private Ground-Water Supplies In Kentucky, Daniel I. Carey, James S. Dinger, O. Barton Davidson, Richard E. Sergeant, Joseph L. Taraba, Thomas W. Ilvento, Steve Coleman, Rayetta Boone, Laura M. Knoth

Information Circular--KGS

About 3.7 million people live in Kentucky, of which 1.9 million (52 percent) live in urban areas (roughly defined as any community with 2,500 or more people) and 1.8 million (48 percent) live in rural areas (University of Kentucky, 1993). Figure 1 summarizes sources of drinking water for Kentucky residents. About 70 percent of Kentuckians get their daily supply of water from surface-water sources - lakes and streams; about 25 percent get their water from ground-water wells; and about 5 percent get their water from other sources - springs, cisterns, ponds, or hauled water.

Federal Preemption Of State Products Liability Doctrines, Richard C. Ausness

Law Faculty Scholarly Articles

Federal agencies now regulate the manufacture, design, and labeling of hundreds of consumer products. For example, the Consumer Product Safety Commission promulgates "consumer product safety standards" for a number of consumer products. Likewise, the National Traffic and Motor Vehicle Safety Act of 1966 authorizes the National Highway Transportation Safety Administration to develop safety standards for automobiles and other motor vehicles. Additionally, the Food and Drug Administration (FDA) exercises extensive control over prescription drugs, biologics, medical devices, and over-the-counter drugs. The FDA also regulates food labeling.6 Finally, Congress has established statutory labeling requirements for cigarettes, smokeless tobacco products, and alcoholic beverages. …

Use Of High-Energy Radiation For Degradation Of Environmental Pollutants, Robert D. Guthrie, Manjiri Patwardhan

KWRRI Research Reports

The purpose of this project was to explore the advantages and/or limitations of high-energy radiation treatment as a method for degrading organic pollutants, particularly aryl halides, in an aqueous medium. We have done analyses of ⁶⁰Co-irradiated samples and kinetic studies using pulsed electron beams. For aryl halides containing no more than two fused rings, the main products detected are those of simple halogen replacement by hydrogen, although the amount of aryl halide destroyed was always greater than the total amount of products detected. To accomplish halogen replacement by H, the reaction solvent may not be pure water but must …

Field Calibration Of A Transient Model For Broiler Misting, Richard S. Gates, Douglas G. Overhults, Robert W. Bottcher, Shu Hui Zhang

Biosystems and Agricultural Engineering Faculty Publications

A transient model to predict temperature within a tunnel ventilated broiler house during misting is developed. The model is calibrated with field data to obtain steady-state constants; transient predictions are compared to measured temperatures during cyclic misting for two different size birds. Measured temperatures during cyclic misting are shown to swing between steady-state asymptotes predicted from the model. Transient response of the model was faster than measured temperature data, in part due to temperature sensor dynamic response. The model predicts the length-wise temperature profile within the building during misting, and can be used to investigate alternate misting strategies and designs. …

The Effects Of Sex And Sexual Orientation On Attractiveness Judgments: An Evolutionary Interpretation, William R. Jankowiak, Elizabeth M. Hill, James M. Donovan

Law Faculty Scholarly Articles

If attractiveness judgments reflect biologically important reproductive criteria, men should base judgments of potential partners on objective physical criteria more than do women; homosexuals and heterosexuals of the same sex should perceive attractiveness in the same terms, regardless of the sex-object choice. To test this theory, photographs of men and women (20 each) were presented to members of four subject groups, solicited on an opportunistic basis. Subjects were asked to rank the sets of photographs separately on the dimensions of physical attractiveness and general social attractiveness. We found some sex differences across sexual orientation. There was less variation among men …
