College publications are given 2-part "pub numbers" that are used to identify them. The first part (the prefix) is a set of letters that indicates which series the document belongs to. A series is a grouping of documents that share similar content. The second part of the pub number is just a sequential number.

Drone Fungicide Applications in Corn

3/5/2021 (new)
Authors: Ricky Arnett, Pat Hardesty, Nick Roy, Kiersten Wise

Drone technology has improved in recent years and has also become more accessible. In Kentucky, commercial drone fungicide application is now an option in several areas. Drones specifically designed to apply products can potentially be used to apply fungicide in fields that are not accessible to other aircraft. This publication describes experiments to determine if drone fungicide applications can reduce foliar diseases in corn and discusses factors to consider when using drone technology to apply fungicides.

Chemical Control of Turfgrass Diseases, 2020

11/19/2019 (major revision)
Authors: Gregg Munshaw, Paul Vincelli

Turgrasses under intensive management are often subject to outbreaks of infectious diseases. Good turf management practices often greatly reduce the impact of disease by promoting healthy plants that are better able to resist infections. Even under good management, however, diseases sometimes cause excessive damage to highly managed turfgrasses. The proper use of fungicides in these instances, in conjunction with good cultural practices that promote quality turf, can be an important part of an overall disease-management program.

Genetically Engineered Crops: Emerging Opportunities

6/28/2017 (minor revision)
Authors: Paul Vincelli

In certain biotech crops, their genetic material (DNA) has been purposefully manipulated in the laboratory. These genetically engineered crops are often called "GMOs," an acronym for "genetically modified organisms." These GMOs are the focus of this publication.

Sampling for the Tall Fescue Endophyte in Pasture or Hay Stands

4/10/2017 (minor revision)
Authors: Ray Smith, Tina Tillery, Paul Vincelli

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.

Plant Diseases: Kentucky Master Gardener Manual Chapter 6

3/2/2016 (major revision)
Authors: Kelly Jackson, Kimberly Leonberger, Robbie Smith, Nicole Ward Gauthier

Anyone who has ever planted a garden knows not only the rewards of beautiful flowers, fruit, and/or vegetables, but also the disappointment when plants become diseased or damaged. Many factors cause plants to exhibit poor vigor, changes in appearance, or even death. This chapter focuses on those living organisms that cause disease: fungi, water molds, bacteria, viruses, nematodes, phytoplasmas, and parasitic plants.

Fundamental Principles of Plant Pathology for Agricultural Producers

3/9/2015 (major revision)
Authors: Paul Vincelli

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.
