Filter by Series

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.

Series: Plant Pathology



Fungicide Efficacy for Control of Corn Diseases
9/28/2017 (new)

The Corn Disease Working Group (CDWG) developed ratings for how well fungicides control major corn diseases in the United States. The CDWG determined efficacy ratings for each fungicide listed in the table by field testing the materials over multiple years and locations. Ratings are based on the product's level of disease control and does not necessarily reflect yield increases obtained from product application. A product's efficacy depends upon proper application timing, rate, and application method as determined by the product label and overall disease level in the field at the time of application. | PPA-49

Fungicide Efficacy for Control of Wheat Diseases
9/28/2017 (new)

The North Central Regional Committee on Management of Small Grain Diseases (NCERA-184) has developed the following information about fungicide efficacy for the control of certain foliar diseases of wheat for use by the grain production industry in the United States. The efficacy ratings for each fungicide listed in this table were determined by field testing the materials over multiple years and locations by the members of the committee. | PPA-48

Genetically Engineered Crops: Emerging Opportunities
6/28/2017 (minor revision)

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. | PPA-47

Sampling for the Tall Fescue Endophyte in Pasture or Hay Stands
4/10/2017 (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. | PPA-30

Chemical Control of Turfgrass Diseases, 2017
4/4/2017 (major revision)

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. | PPA-1

Plant Diseases: Kentucky Master Gardener Manual Chapter 6
3/2/2016 (major revision)

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. | PPA-46

Fundamental Principles of Plant Pathology for Agricultural Producers
3/9/2015 (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. | PPA-41
