PPA-30: Sampling for the Tall Fescue Endophyte in Pasture or Hay Stands
Ray Smith, Tina Tillery, Paul Vincelli | Apr. 10, 2017 (Minor Revision)
Most of the tall fescue growing in Kentucky is colonized by the tall fescue endophyte, a fungus which causes disorders in livestock that feed on the infected grass. The animal disease syndrome is called fescue toxicosis, which some researchers estimate may cost Kentucky producers over $200 million yearly. This problem can be greatly reduced by identifying the infected fields and replacing them with endophyte-free or novel endophyte tall fescue varieties or by managing them in a way to minimize the impact of the endophyte on herd productivity. One of the simplest ways to reduce toxicity symptoms in cattle is add red and white clover to existing tall fescue stands.
PPFS-MISC-7: Genetically Engineered Crops: A Review of Concerns and Benefits
Paul Vincelli | Oct. 1, 2016 (New)
Genetically engineered crops are plants that have had their genetic material (DNA) purposefully manipulated in the laboratory to produce a particular beneficial outcome. These types of crops are often called genetically modified organisms, or GMOs. Commercial genetically engineered crops are designed to have limited and precise genetic changes that provide one or more benefits to humans or the environment.
PPA-41: Fundamental Principles of Plant Pathology for Agricultural Producers
Paul Vincelli | Mar. 9, 2015 (Major Revision)
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, which 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.
PPFS-AG-F-9: Managing Diseases of Alfalfa
Ray Smith, Paul Vincelli | Dec. 1, 2014 (New)
Alfalfa can be a vigorous and productive forage crop for Kentucky farmers. Like all farm crops, however, alfalfa is subject to infectious diseases that can limit forage production. Managing these diseases is an important part of economical alfalfa production.
PPFS-OR-T-11: Disease Management in the Home Lawn
Gregg Munshaw, Paul Vincelli | Nov. 1, 2014 (New)
This publication describes lawn management practices that can help control diseases of turfgrasses commonly used in home lawns--Kentucky bluegrass, tall fescue, and perennial ryegrass. You can control diseases of turfgrasses most effectively by using as many of the following lawn management practices as feasible.
PPFS-AG-F-8: Kentucky Plant Disease Management Guide for Forage Legumes
Paul Vincelli | Oct. 1, 2014 (New)
Disease management in forage legumes relies heavily on using disease-resistant varieties and employing sound agronomic practices. It is important to integrate both of these strategies into a comprehensive disease management program. Failure to consider one or the other will compromise the success of your efforts. The appropriate use of pesticides sometimes plays a significant role in managing certain diseases, but it is secondary to sound cultural practices and proper variety selection.
ID-222: Considering the Environment in the Maintenance of Your Kentucky Lawn: A Season by Season Approach
Gregg Munshaw, Paul Vincelli | Jul. 30, 2014 (New)
Most people do not realize the environmental benefits of lawns. Lawns are known to cool the air, reduce soil erosion, remove dust and pollutants (including CO2) from the air, reduce run-off of water and pollutants, create oxygen for humans, and improve soils over time by supplying organic matter. Lawns are also important aesthetically and have been shown to improve human well-being. However, to be 100 percent environmentally friendly, we could never fertilize or water our lawns and only mow with a self-propelled reel mower. Or, we could get rid of our lawn altogether. Neither of these options is particularly appealing for most people. We can, however, have a high quality lawn and reduce our impact on the environment by doing some very simple things at the right times of the year. The following guide will walk you through a series of steps that are important for keeping your lawn looking thick and healthy and at the same time reducing pests and the need for chemicals and other inputs.
PPFS-MISC-2: Some Principles of Fungicide Resistance
Paul Vincelli | Jan. 1, 2014 (New)
Fungicides are important tools in modern crop production. Unfortunately, one of the risks of using these products is that fungi sometimes develop resistance to them. Resistance development is a concern because the products may become less effective--or even useless--for controlling resistant pathogens and pests. This is a concern for all pesticides, including fungicides, insecticides, and herbicides. This fact sheet is intended to help pesticide applicators better understand this process.
PPFS-AG-F-7: Rating Scale for Brown Stripe of Orchardgrass
Leah Saylor, Ray Smith, Paul Vincelli | Jul. 1, 2013 (New)
As of right now, there is little published on how to assess foliar disease severity in forage grasses in order to determine the percentage which may be diseased. This publication provides a tool for visually determining the percentage of diseased foliar tissue in orchardgrass. It is based on the observation of individual leaves; however, it is hoped that eventually a rating system will be devised that provides disease percentages for entire plots.
PPFS-MISC-6: Assessing Foliar Diseases of Corn, Soybeans, and Wheat: Principles and Practices
Don Hershman, Paul Vincelli | Nov. 1, 2011 (New)
This publication provides basic information on how to conduct disease assessments in on-farm trials. The focus is on foliar diseases, since root diseases are much more difficult to assess properly. The publication begins with fundamentals of proper design of field trials.
