From BioCycle Magazine June 1999, Page 61 COMPOST USERS FORUM Using Compost To Control Plant Diseases Researchers at Ohio State University evaluate the prospects for composts and biocontrol agents to replace methyl bromide to protect plants. Tom J.J. De Ceuster and Harry A.J. Hoitink MB fumigation is most important in intensive horticultural systems where continuous crop monoculture is practiced and losses caused by soilborne plant pathogens are most severe. As a result, profitability of these crops relies strongly on the availability of MB. Strawberries in California and fresh market tomatoes in Florida are classic examples. Tomatoes, strawberries, lettuce, cucumbers, roses and chrysanthemums are examples for the West European growing region. Phytophthora cinnamomi because it was often reintroduced after soil fumigation with infected plants or in irrigation water. Heavy Phytophthora root rot losses occurred on a regular basis on rhododendron, azalea and other crops highly susceptible to this disease. Emphasis On Biological Alternatives To MB Several alternatives to both MB fumigation and the pathogen recontamination problem are now under development. One approach is to substitute MB with another less problematic but effective fumigant. A second is to inoculate sterilized soil with beneficial microorganisms after treatment. A third represents a return to an old and all but forgotten practice, which is to replace sterilization procedures with soil organic matter management that provides control. Examples are applications of animal manures, green manures, composts or biocontrol-agent-fortified composts, which as described below can provide effective control of diseases, as well as insects and weeds if combined with herbicides and specific cultural practices.

Agrios This course will prepare the student to understand the role of plant pathogens in crop production. Diseases are often a major limiting factor in crop production, and understanding the biology of the pathogen(s) will enable the grower to effectively manage disease problems. In addition, this course offers insight into the relationships between plants and microbes. Laboratories will consist of field observations of plant disease, microscopic observations of diseases and pathogens, and methods for the culture and isolation of plant pathogens.

Research is conducted on a diverse range of crops (arable and vegetable crops, fruit and nut trees, grapevines) and across a number of science disciplines (molecular biology, mycology, microbiology, biochemistry). Research projects conducted in the group covers aspects of disease diagnosis, pathogen biology, plant disease epidemiology, molecular biology of pathogens, disease control methods, in particular, biological control and the development of integrated disease management systems. Current Research Focus Biological control of soil-borne plant diseases using naturally occurring beneficial fungi and bacteria. Trichoderma Gliocladium Coniothyrium species and spore forming bacteria have been identified with activity against a number of key fruit and vegetable pathogens. Current research projects cover screening methods to identify potential biocontrol agents, mechanism of action studies (eg mycoparasitism, antibiosis), ecology of biological control agents, glasshouse, field evaluation and commercial development of biocontrol products. This work is conducted in close liaison with industry and business partners (contact person - Professor Alison Stewart).

HOME INTRODUCTION Plant Pathology Division v Fungal Disease Laboratory Major achievements on fungal disease research in recent years include: (1). Diagnosis of plant diseases, identification of fungal pathogens, and preservation of important fungi. More than 70 species of new recorded fungal pathogens and diseases have been identified , including Pythiogeton Trichoderma species were obtained and various techniques for mass production of bio-pesticides of these microbes have been developed. These microorganisms could enhance plant growth and reduce several diseases of many agricultural crops. Symptoms (left) of water oat stem rot caused by Pythiogeton zizaniae .

Phytopathology From Wikipedia, the free encyclopedia. Phytopathology or Plant Pathology is the science of diagnosing and managing plant diseases . Its covers all infectious agents that attack plants and abiotic disorders, but does not include herbivory by insects mammals , etc. Common plant pathogens (in rough order of importance) include species from these groups: Fungi - the most common pathogens (root rot fungi, moulds, rusts, and mildews). Water moulds (Oomycetes) - such as Phytophthora infestans potato blight Bacteria prokaryotic organsisms which include as many as 18 genera. Viruses - more than 700 are plant pathogens, comprised of only protein and DNA Roundworms (Nematoda) - both as pathogens and vectors , the only animals normally regarded as plant pathogens. Viroids - small, single-stranded RNA pathogens causing a dozen plus diseases. Parasitic angiosperms - plants that parasitize other plants, mistletoe and witchweed are common examples. Slime moulds (Myxomycetes) - usually not actual pathogens but may be aesthetically unpleasant. Phytomyxea - true pathogens represented by the genera Polymyxa and Plasmodiophora Significant abiotic disorders can be caused by: Natural Drought Frost damage, and breakage by

Edited by Thomas A. Evans, Gail L. Schumann, and Frank H. Tainter SCROLL DOWN TO ORDER THIS TITLE. This resource is composed of three parts: a videodisc, a database, and a set of student lessons. The videodisc contains nearly 10,000 full-color plant disease images - compiled from Plant Disease journal, APS PRESS Compendia, APS PRESS slide sets, and private slide collections. The database contains records describing each image, together with retrieval software to find specific images. The student lessons combine text and images on-screen, allowing the student to study major pathogens at his or her own pace. ISBN 0-89054-142-6 For basic research, education, or extension You don't need an interactive computer system to conduct basic image research and viewing. With your personal computer, you can use the database to obtain a list of all slide images involving a given pathogen, disease, host, etc. Open any record within this list and you will see the description of the image, as well as a number indicating its location on the videodisc. By entering this number on your videodisc player, you can display the image on screen. For interactive educational use Now students can study plant pathogens and disease symptoms on their own-all at the touch of a computer key!
