For example, searching for possum fertility will return documents containing either "possum" or "fertility" or both. If you're looking for more than one word in a document, place the word "AND" between the words. For example, if you're looking for documents which contain both possum and fertility, search for possum and fertility. To find a document with the exact phrase possum fertility enclose the query in quotes. ie: " possum fertility ".

Reprints A mysterious foe Eric Liskey Editor www.grounds-mag.com Mar 1, 2001 12:00 PM E-mail this article Plant pathogens often are more difficult for grounds managers to deal with than other types of pests. This may be due to the fact that you often can't actually see the pathogen itself. You may only see the symptoms, which can be difficult to define and also may closely resemble several different diseases. (How many possible causes can you think of for a dead patch of grass? Or dieback in a tree?) In other words, you may have to work a little harder to diagnose the problem correctly. Perhaps this relates to the human tendency to fear the mysterious. Diseases often seem to come out of nowhere or occur randomly. In fact, pathologists know better. If a disease shows up one year but not the next, there's usually a reason. Probably certain environmental conditions required by the pathogen occurred one year but not another. To give you a better grasp on new as well as ongoing disease problems, we're focusing this issue of

FEATURE ARTICLE Biological Control Of Plant Pathogens A Note From the Project Director: In the May 1995 issue of MBCN we acknowledged that while weed and plant disease biological control are very important, our grant specifies a newsletter devoted to insect biological control. The feature article of that issue was an introduction to the biological control of weeds . In this issue, we are pleased to have an article by Dr. Jennifer Parke of the University of Wisconsin, Department of Plant Pathology, introducing the subject of biological control of plant diseases. Plant diseases are caused mainly by fungi, bacteria, viruses and nematodes. Biocontrol of plant disease involves the use of an organism or organisms to reduce disease. In this article, I will emphasize biocontrol of diseases caused by fungi and bacteria. Biocontrol includes management of resident populations of organisms (the 'black box' approach) and introductions of specific organisms (the 'silver bullet' approach) to reduce disease. The 'Black Box' Approach.

News and Reviews Slide Set on Biological Control of Plant Pathogens A Pictorial Guide to Biological Control of Plant Diseases , compiled by J. E. Loper and L. J. Stowell and originally produced in 1992 by The American Phytopathological Society, is currently available for purchase. This slide set is an excellent resource for anyone who needs to describe principles of biological control or show specific examples of plant disease biocontrol. The slide set consists of 70 full-color slides organized by disease along with the biocontrol strategy for each. Introductory slides provide a definition of biological control and a summary of tactics, and list different mechanisms of biocontrol. Title slides inserted at the beginning of each of the 13 examples list the name of the disease, the pathogen, and the biocontrol. Examples were carefully selected to represent the different biocontrol mechanisms and to include diseases caused by fungi, bacteria, and viruses on a variety of crops and forest tree species. Modification of cultural practices to control disease is illustrated by the use of green manures to reduce Verticillium wilt of potato , incorporation of organic amendments to avocado orchards to maintain soil suppressiveness to Phytophthora root rot , soil packing to cure Valsa canker disease of apple , and monoculture of wheat to develop soils suppressive to take-all of wheat. Examples of biocontrol through the use of antibiotic-producing antagonists include application of bacteria to wheat seed to control take-all, inoculation of woody plants with

College of Food, Agricultural and Environmental Sciences Madden, Laurence Vincent Professor Areas of Special Interest: Epidemiology of plant diseases, disease modeling and prediction, and crop biosecurity. Who am I? Teaching Interests I teach a graduate level course in Plant Disease Epidemiology, where we use the textbook I co-wrote with the late Lee Campbell. I also give lectures in other courses, especially on biosecurity issues. I am very active advising graduate students and post-doctoral researchers. Research Area My research is focused on understanding and describing plant diseases at the population level and relating disease intensity to crop losses. I use mathematics and statistics to characterize disease epidemics in time and space with the goal of determining which biological and physical factors best predict: disease invasion, persistence, outbreaks, and the magnitude of disease spread. Recently, I have been using models to develop approaches for assessing the threat of plant pathogens as bioterrorism weapons against U.S. crops. For the last 15 years I have worked heavily on determining how rainfall affects splash dispersal of fungal spores. This basic work has increased our understanding of how fungal spores move within fields and between fields, and has shown how to better control some economically important diseases.

19. PLANT PATHOLOGY DEFINITION OF plant PATHOLOGY. The study of plant diseases is known as plant pathology.Infectious diseases are caused by living organisms called pathogens. http://www.hcs.ohio-state.edu/mg/manual/path.htm

PLANT PATHOLOGY T hroughout history, loss of crop yields from disease have had severe effects on the human race. The Irish potato famine in the 1800's killed 1.5 million people, one fourth of Ireland's total population. The crop was lost to late blight of potato, a fungal disease. In the mid 19th century downy mildew grape disease was accidentally introduced in Europe. Downy mildew of grape almost destroyed the vineyards in France, Germany and Italy. Ergot of rye grain causes hallucinations and sometimes deadly illness. Massive European epidemics caused by ergot of rye occurred frequently during medieval times. In the early 20th century the American Chestnut tree was wiped out by an Asian blight disease. The chestnut was a major source of lumber at the time. There are at least 50,000 diseases of crop plants. New diseases are discovered every year. About 15% of the total U.S. crop production is lost annually to infectious diseases despite improved cultivars and disease control techniques. Damage from disease has not been eliminated. Disease-causing organisms (pathogens) multiply and mutate rapidly. They develop genetic resistance to chemical controls and have the ability to infect new hybrids. Good gardening practices and an understanding of plant pathology are the first line of defense against disease.
