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.

Possible Causes of Yellowing Alfalfa

2/16/2018 (new)
Authors: Chris Teutsch, Paul Vincelli, Kiersten Wise

During spring, several leaf spotting diseases--including Leptosphaerulina (Lepto) leaf spot and spring black stem/leaf spot--are common in alfalfa. Leaf spotting diseases result in distinct round to elongated spots that sometimes have a dark margin. Very wet weather in spring and early summer favor activity of leaf spotting diseases in first and second cuttings. Wet and humid weather during summer favor other leaf spotting and blighting diseases. All leaf spots and blights weaken plants, but alfalfa often outgrows the damage in later cuttings. Maintain a regular cutting schedule, cutting at 30- to 35-day intervals.

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.

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.

Brown Patch Disease in Kentucky Lawns

12/1/2014 (new)
Authors: Gregg Munshaw, Paul Vincelli

Brown patch, also called Rhizoctonia blight, is a common infectious disease of turfgrass. All turfgrasses grown in Kentucky lawns can be affected by brown patch. However, this disease is usually destructive only in tall fescue and perennial ryegrass during warm, humid weather. While brown patch can temporarily harm a lawn's appearance, it usually does not cause permanent loss of turf except in plantings less than 1 year old.

Authors: Paul Vincelli

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

7/30/2014 (new)
Authors: Gregg Munshaw, Paul Vincelli

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.

Some Principles of Fungicide Resistance

1/1/2014 (new)
Authors: Paul Vincelli

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.

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.

Foliar Fungicide Use in Corn and Soybeans

10/1/2011 (new)
Authors: Don Hershman, Cheryl Kaiser, Paul Vincelli

Interest in the use of foliar fungicides for corn and soybean has expanded dramatically in the U.S. over the past few years, resulting in a major change in how these crops are being produced on many farms. Until recently, foliar fungicides for soybeans and corn were reserved for seed production fields to protect seed quality in very specific circumstances or for specialty crops. Applications for the purpose of protecting crop yield were rarely economical. However, the current trend in Kentucky, as well as many other corn/soybean producing states, is towards an increased use of foliar fungicides on these crops as a means of maximizing yields.

Authors: Tom Barnes, Ric Bessin, Jeffrey Bewley, Roy Burris, Tim Coolong, Lee Meyer, Joe Taraba, Paul Vincelli, George Wagner

Nearly all climate science experts agree that global warming is occurring and that it is caused primarily by human activity. Regardless of what you may read on blogs or in the media, there is no meaningful scientific controversy on these points. The future impacts of global warming are difficult to predict, but the changes caused by greenhouse gases are expected to increasingly affect Kentucky agriculture.

Real-time PCR Detection of Xylella fastidiosa is Independent of Sample Storage Time and Temperature

11/1/2010 (new)
Authors: Bernadette Amsden, John Hartman, Paul Vincelli

The xylem-limited bacterium Xylella fastidiosa, first associated with Pierce's disease of grapevines and alfalfa dwarf disease in 1973 (4) continues to be an economically important pathogen of several commercial crops. It also causes bacterial leaf scorch in urban shade trees such as sycamore, oaks, maples, mulberry, and elm (5). The usual course of action, in an effort to control the spread of this pathogen by insect vectors (9), is to prune out infected branches and vines or to rogue infected plants. Therefore, timely testing of suspect hosts is important.

Authors: Paul Vincelli

Anthracnose is primarily a disease of high maintenance turfgrass, such as annual bluegrass (Poa annua) and creeping bentgrass (Agrostis stolonifera) at golf courses. In Kentucky it can be a disfiguring disease of creeping bentgrass under putting green management conditions during summertime (June to September). The disease may make its appearance on intensely managed annual bluegrass somewhat earlier (April to September). The anthracnose pathogen can incite a foliar blight phase or the more destructive basal rot phase.

Crown Rots of Alfalfa

5/1/2009 (minor revision)
Authors: Paul Vincelli

Crown rots are chronic disease problems of alfalfa throughout the world. Crown rots cause loss of stand and forage yield in several ways. If the crowns are rotted severely enough, infected plants will die simply by being choked off. Carbohydrates for winter survival are stored in the crown and upper taproot. By rotting this area, crown rots also make alfalfa plants more sensitive to winter kill. Some crown rot fungi produce toxins, thus weakening or even killing the plant.

Risk Factors for Sclerotinia Crown and Stem Rot in Fall-Seeded Alfalfa

12/1/2008 (minor revision)
Authors: Paul Vincelli

Alfalfa seeded during late summer or fall is susceptible to the destructive disease Sclerotinia crown and stem rot. Fall-seeded stands are particularly vulnerable to this disease because the young seedlings have not had sufficient time to develop adequate resistance before infectious spores of the pathogen are produced in late October. In contrast, spring-seeded stands are able to develop larger, more resistant crowns prior to this infectious period. Thus, spring plantings are better able to withstand an attack, should these air-borne spores be present in the field.

Authors: Paul Vincelli

Rhizoctonia fungi, particularly Rhizoctonia solani, are found in most agricultural soils in Kentucky. These fungi are natural soil inhabitants that colonize and live on dead organic matter. Under the right environmental conditions, the Rhizoctonia organisms are often able to attack living plants, including alfalfa. When warm, wet conditions prevail, Rhizoctonia fungi can cause just about every conceivable type of alfalfa disease.

Diseases of Concern in Continuous Corn

10/1/2008 (minor revision)
Authors: Don Hershman, Paul Vincelli

Although most corn in Kentucky is planted following a rotation to other crops, individual producers are often interested in planting corn following corn. In these situations, one of the main concerns voiced by producers is increased pressure from diseases, and rightfully so. Crop rotation is one of the most fundamental disease control practices available. Rotating to other crops deprives pathogens (disease-causing microorganisms) of a food source and exposes them to "starvation." Furthermore, as infested crop residues decompose, pathogens are exposed to antagonism by native soil microbes. These mechanisms have the effect of naturally reducing the populations of many pathogens in the soil.

Authors: Paul Vincelli

Corn seeds and seedlings are susceptible to infection by a number of soilborne fungi. When planted into cool, wet soils, seeds may decay before or after germination. Affected plants that survive past the seedling stage may go on to produce an ear if nodal roots develop normally, although stunting and reduced ear size can occur as a result of seedling diseases. Severely affected plants may die during stressful weather as the result of an inadequate root system.

A Comprehensive Guide to Corn Management in Kentucky

9/30/2001 (new)
Authors: Ric Bessin, Morris Bitzer, J.D. Green, Jim Herbek, Greg Ibendahl, Jim Martin, Sam McNeill, Michael Montross, Lloyd Murdock, Paul Vincelli, Ken Wells

The corn grown in Kentucky is used mainly for livestock feed and as a cash crop. As a cash crop sold from the farm, corn ranks third behind tobacco and soybeans but is the number one row crop in terms of acreage. Because the cost of producing an acre of corn is high and the value per bushel has declined in recent years, producers must manage and market their corn crop more carefully for adequate profits. The goal of this publication is to serve as a guide for corn production strategies that focus on efficient use of resources and provide the principles and practices for obtaining maximum, profitable corn yields.
