Bacterial Diseases on Geranium January 2004 Bacterial diseases on geraniums that growers should be on the lookout for are Xanthomonas campestris pv. pelargonii , the agent of bacterial blight disease of geraniums and Ralstonia solanacearum the causal agent of southern bacterial wilt. Southern bacterial wilt is caused by two specific races of R. solanacearum , Race 1 and Race 3. Race 1 is found in the southern United States whereas Race 3 is considered an exotic pathogen and is therefore regulated under federal quarantine. R. solanacearum Race 3, biovar 2 is also one of 10 pathogens on the list of "Select Agents and Toxins" as part of the Agricultural Bioterrorism Act of 2002. The concern is that Race 3, biovar 2 has the potential to carryover to potato and other solanaceous crops or weeds. (Geranium Bacterial Disease pictures) Bacterial blight of geraniums, caused by Xanthomonas campestri s pv. pelargonii can infect Zonal geraniums ( Pelargonium x hortorum ), ivy geraniums ( Pelargonium peltatum ), Regal or Martha Washington geraniums (

Related Categories Description Over the last fifty years, there has been an increasing recognition that eucalypts are vulnerable to a wide range of diseases. They have suffered destructive epidemics, particularly of dieback caused by the cinnamon fungus in native forests, of foliar diseases and cankers in plantations, and of dieback of remnant trees on agricultural and grazing land. This has stimulated intensive research into the causes and management of diseases of the eucalypts. This work represents a comprehensive review of our current knowledge of the health and diseases of eucalypts.

Slusarenko R.S.S. Fraser Society for General Microbiology, Reading, UK L.C. van Loon Faculty of Biology, Utrecht University, The Netherlands The chapters are organised and written to make an advanced textbook rather than simply a collection of reviews or something resembling conference proceedings. Thus, authors have largely concentrated on a didactic approach and the book should remain useable for several years in spite of the rapid progress in research. The text is aimed at advanced students in the field of plant pathology as well as researchers requiring an integrated picture of plant resistance to pathogens. Contents and Contributors Review(s) The work is an excellent and advanced textbook on resistance mechanisms to plant diseases and host-pathogen interactions. In addition to the scientific value of individual chapters, the highly didactic approach taken is of benefit. The book can therefore, be used not only by researchers but also advanced students of biology and agriculture focused on plant pathology. Authors, editors and publishers are to be recommended for an excellent piece of work. Plant Protection Science, 37:4 (2001)

Agricultural Disease Prevention in Home Vegetable Gardens Patricia Donald, Department of Plant Microbiology and Pathology Lewis Jett, Department of Horticulture Vegetable gardening is the number one hobby in the United States. Keeping a garden healthy and attractive requires attention not only to its size and location but also to the soil, water availability, sunlight and air circulation in the garden. These environmental conditions can determine susceptibility to plant diseases. Diseased plants are unsightly and also detract from the enjoyment and fruits of the hobby. Diseases affect home garden vegetable plants every year. Plant pathogens become established when environmental conditions are favorable. Losses due to disease can be reduced through a combination of proven disease-prevention methods: Select adapted, disease-resistant varieties. Use transplants that are free from disease. Plant closely related vegetables in separate areas of the garden (see Table 1). Rotate garden areas to prevent planting closely related vegetables in the same area year after year. Control weeds that compete with vegetables or harbor plant pathogens.

Forest and Shade Tree Pathology Concepts of Disease and Names About this site Outline of this page: Disease Names of diseases Types of diseases Pathogens ... Signs and symptoms Disease Forest pathology is the study of tree diseases. What do you think a disease is? One textbook says: "Any deviation in the normal functioning of a plant caused by some type of persistent agent." What is normal? What if all the trees in a population have a particular fungus causing leafspots? Is that then normal, and thus not a disease? What is "persistent?" What is the difference between injury and disease? You should know that insects are traditionally excluded from the concept of disease, though some are persistent and their interaction with plants fits most definitions of disease. Nematodes are traditionally included. Do genetic defects and nutrient deficiencies fit the definition? For these cases, you may want to add to the definition the phrase, "or condition." Although some consider that traditional definitions of disease imply that the pathogen is all-important and leave the impression that the pathogen and disease are the same thing, the traditional disease triangle seems to cover this problem for all sorts of diseases. It is a useful, time-tested model of disease taught in most introductory courses and commonly used conceptually by pathologists. It is a useful model of disease because it emphasizes the interaction of the environment, a

Careers Email this page Biological Control Of Plant Diseases Genetic Diversity in Cacao Plant Responses To Rising Atmospheric Carbon Dioxide Major Research Projects: Biological and Chemical Disease Control Plant Responses to Rising Atmospheric Carbon Dioxide Crop Simulation Models for On-Farm Decision Support Narcotic Crop Control Strategies Objective: Approach: Classical and molecular techniques will be used to study the ecology and genetics of the interactions and evaluate the genetic diversity among beneficial and pathogenic microorganisms to understand their role in the disease environment. Similar techniques will be used to dissect the response of pathogens, biocontrol agents and host plants to biotic and abiotic stresses including each other. Traditional and innovative methods will be developed to screen biocontrol agents, fungicides, and their formulation additives for their abilities to enhance control of major diseases of tropical crops. In controlled conditions research will be carried out to evaluate the abiotic stress (soil acidity/alkalinity, soil nutrient/moisture levels, elevated CO and temperature) on inter-intra specific differences for production and plant health of alternate crops. In collaboration with government, non government and international research organizations and universities of tropical and North America and Caribbean countries, carry out field studies to assess the impact of integrated pest management strategies, soil fertility and crop management on productivity and health of diversified high value alternate crops in order to optimize production potentials, tolerance to abiotic stresses, ecological adaptability, and disease control strategies in order to ensure sustainability.
