41. U Of M Website Can Help Diagnose Plant Diseases
Early diagnosis of plant disease problems is the most critical step in managingplant pathogens and minimizing their impact, says Beckerman.

U of M website can help diagnose plant diseases
If you have pallid petunias or cankered cucumbers, a visit to a University of Minnesota website can help you figure out the cause of the problem. Two new additions to the Plant Disease Diagnostics website at are designed to help you diagnose vegetable and bedding plant diseases. The diagnostics website is a project of the plant pathology staff of the U of M Extension Service's Yard and Garden Clinic. The website guides users through the process of diagnosing plant diseases. Plant categories include bedding plants, fruit, roses, shrubs and vines, trees, turf and vegetables. After clicking on a category, you begin by identifying the affected host plant. Then you can narrow down the possible problems affecting the plant. What if you can't identify your host plant? "There are links to help with that process," says Janna Beckerman, U of M Extension plant pathologist. "With the recent addition of two new categories, bedding plants and vegetables, you can now access information to help diagnose problems with these plants. We will continue to add new host plants, so we encourage you the check back soon if you don't find what you're looking for on the first visit." Once you have clicked on the name of the host plant, the next step is to determine which part of the plant is affected-leaves, flowers, stems or roots. Links take you to a page with photographs of common disease problems and descriptions of symptoms. This page helps you match the problems you are seeing with a specific disease.

(1190 Borregas Ave., Sunnyvale, CA 94089-1302; Tel: 408/541-4191, Fax: 408/541-4192; Website: has entered into a Cooperative Research and Development Agreement (CRADA) with the U.S. Department of Agriculture (USDA) to develop DNA tests for rapid, field diagnosis of plant diseases threatening major cash crops. The tests will be developed and optimized for use on Cepheid's portable Smart Cycler TD and its GeneXpert systems. Scientists with the USDA's Agricultural Research Service (ARS) will design DNA primers and probes to detect organisms responsible for several diseases posing serious threats, including citrus canker, Karnal bunt of wheat, Pierce's disease in grape vines, and plum pox in stone fruits. Cepheid retains first rights to license resulting diagnostic tests for commercial use on its systems. The company expects to supply the first samples of lyophilized, high- stability, high-performance testing kits for evaluation by the USDA during the first half of 2002. Employing real-time polymerase chain reaction (PCR), Cepheid's portable systems are capable of detecting trace levels of DNA from disease-causing pathogens, including bacteria, viruses, and fungi, in 20 to 30 min. Until now, PCR tests have not been widely used for diagnosis of plant diseases, because they are typically performed on costly instruments available only in laboratories.

More people are getting sick from eating fresh fruits
St. Paul, MN (January 27, 2003) Salmonella, E. coli, shigellosis, hepatitis A, and Norwalk these food-borne diseases can produce symptoms that run from the mild to life-threatening. The young and old are particularly vulnerable and while consumption of beef and poultry have been the most common sources of such infections, fresh fruits and vegetables are being increasingly implicated in such outbreaks. So much so, that plant disease scientists are now taking a closer look at this issue. "Historically, human pathogens like E. coli and Salmonella have rarely been associated with plants, so plant disease scientists have not looked at them directly," says J.W. Buck, a plant pathologist at the University of Georgia. But that is changing, says Buck, as such incidences continue to increase. Buck says there is no single reason why the number of reported produce-related outbreaks in the U.S. per year doubled between 1973-1987 and 1988-1992 and why they continue to rise. Possible explanations include the simple fact that we are eating more fruits and vegetables than ever before. But experts agree that there is more to it than that and that our food production practices likely bear some responsibility. But identifying the exact point along the way, from field to grocery store, where a strawberry or head of lettuce, for example, might have become contaminated can be difficult, if not impossible. Unlike other commodities such as beef and chicken, which are rigorously inspected, methods to detect pathogens on fresh produce are less advanced and the sporadic nature of most contamination further limits the effectiveness of testing.

Real-time PCR and its application for rapid plant disease diagnostics
Norman W. Schaad and Reid D. Frederick
Pages 250-258
Abstract : Rapid-cycle real-time polymerase chain reaction (PCR) methods may revolutionize the manner in which plant pathogens are identified and diseases are diagnosed. As the genomics age progresses and more and more DNA sequence data become available, highly specific primers and fluorescent probe sequences can be designed to yield target amplicons to unique regions of a pathogen's genome. Portable real-time PCR instruments described here are now allowing for diagnostic assays to be run directly in the field or at remote locations other than the standard diagnostic laboratory. Rapid real-time PCR diagnosis can result in appropriate control measures and (or) eradication procedures more quickly and accurately than traditional methods of pathogen isolation. Disease losses are minimized and control costs reduced. Advantages and disadvantages of rapid real-time PCR for the detection of bacterial, fungal, and viral plant pathogens are described. Key words : DNA-based diagnostics, molecular identification, disease diagnosis, bacteria, fungi.

Course Goals:
The primary goal is to study those interactions between higher plants, plant pathogens, and the environment which are important in the occurrence and development of plant disease. Emphasis is placed on the population dynamics and ecology of plant pathogens in the aerial and soil environments. Entry Level:
The course is designed primarily for graduate students in plant pathology and related fields. Plant pathology 120 or an equivalent course is a prerequisite. Any exposure the student has had to microbiology, mycology, ecology, population dynamics, soils, and atmospheric sciences will be helpful. However, no formal background in these areas is required. Course Format:
Three hours of lecture and one hour of discussion are scheduled each week. Some of the discussion is prepared and led by students. Grades are based on one mid-term exam, a final exam and one paper. The paper is written on the epidemiology of a disease of the student's choosing. The paper takes the form of a research proposal and the goal of the proposed research is to gather all the information needed to model and/or forecast epidemics at a given location.

PLANT DISEASE DIAGNOSTICS Biotechnology Information Series (Bio-5) North Central Extension Publication
Iowas State University - University Extension August, 1993 Plant Disease Diagnosis: Moving Out of the Lab and Into the Field ^^^^^ ^^^^^^^ ^^^^^^^^^^ ^^^^^^ ^^^ ^^ ^^^ ^^^ ^^^ ^^^^ ^^^ ^^^^^ The first and most important step in managing a plant disease is to correctly identify it. Although some diseases can be diagnosed quickly by visual examination, others require laboratory testing for diagnosis. These laboratory procedures may take days or even weeks to complete and are, in some cases, relatively insensitive. Delays are frustrating when a quick diagnosis is needed so that appropriate disease control measures may be taken to prevent plant injury, especially when high value cash crops, turf grass, or ornamentals are at stake. Fortunately, as the result of advances in biotechnology, new products and techniques are becoming available that will complement or replace time-consuming laboratory procedures. Many products already are available for use, while others are still in developmental stages. Some procedures require laboratory equipment and training, while other procedures can be performed on site by a person with no specialized training. ELISA Diagnostic Kits
A number of disease detection kits have been developed for use at the site where a disease is suspected. These kits, which in most cases do not require laboratory equipment, are especially useful to growers. Some tests only take five minutes to perform.

blight disease (right).
Curiosity compels some people to research their family tree. But to ARS scientists like microbiologist Kerry O'Donnell and molecular geneticist Corby Kistler, reconstructing the genealogy of plant pathogenic fungi goes beyond curiosity. O'Donnell, at Peoria, Illinois, and Kistler, at St. Paul, Minnesota, along with colleagues at North Dakota State University (NDSU), Fargo, are doing research that may help keep grains from becoming contaminated with toxins that threaten food safety and plant health. Kistler and O'Donnell are among scientists researching toxin-producing Fusarium fungi. These fungi are notorious for causing a disease called scab, or Fusarium head blight, in grains such as wheat and barley, as well as ear and stalk rot of corn. One of their goals is to develop technology for identifying which species cause disease. They also hope to determine each species' range of hosts, geographic distribution, and potential for producing mycotoxins. This information is urgently needed by plant breeders and disease control specialists worldwide to develop effective control measures to minimize the threat of scab.

Pathogens and Antagonists of Plant Disease and Post-Harvest Decay
Pathogens Insects and mites, like plants, humans, and other animals, can be infected by disease-causing organisms such as bacteria, viruses, and fungi. Under some conditions, such as high humidity or high pest abundance, these naturally occurring organisms may multiply to cause disease outbreaks or epizootics that can decimate an insect population. Diseases can be important natural controls of some insect pests. Some pathogens have been mass produced and are available in commercial formulations for use in standard spray equipment. These products are frequently referred to as microbial insecticides, biorational, or bio-insecticides. Some of these microbial insecticides are still experimental, others have been available for many years. Formulations of the bacterium, Bacillus thuringiensis or Bt, for example, are widely used by gardeners and commercial growers. Most insect pathogens are relatively specific to certain groups of insects and certain life stages. The microbial products do not directly affect beneficial insects and none are toxic to wildlife or humans. Specificity, ironically, can be a disadvantage to the commercialization of these products because their small market may limit profitability.
