Prevent agricultural loss with natural disease controls that don’t harm the environment—or the people who live in it Despite the worldwide use of chemicals and pesticides to control the devastating effects of plant disease, the international agribusiness market still suffers extensive economic losses each year. Biological Control of Plant Diseases offers natural alternatives to the synthetic fungicides, pesticides, herbicides, and insecticides that have not only failed to stop pests and pathogens, but have raised serious safety and environmental concerns. The world’s leading plant pathologists examine the use of antagonistic microorganisms, inherent resistance, and natural fungicides for plant protection that’s safe, economical, and effective. Biological Control of Plant Diseases presents up-to-date research findings on disease management to provide you with a single-source reference text for developing a sustainable ecosystem that doesn’t depend on harmful and unhealthy agrochemicals. This unique book acts as a catalyst for change, presenting fresh ideas and innovative strategies for finding meaningful solutions to the problems of disease control. Contributors working in the areas of plant protection, microbiology, plant pathology, biotechnology, ecology, and food safety examine topics that include the application of plant tissue culture, competitive root colonization, mycorrhiza in biocontrol, microbial siderophores, antagonism, and genetic regulation. Topics addressed in Biological Control of Plant Diseases include: soil-borne pathogens rhizobacteria organic acids white rot Trichoderma and Agrobacterium phyllosphere manure-based microbes gray mold disease major fungal diseases mycoparasitism microbial chitinases and much more Biological Control of Plant Diseases is an invaluable reference resource for extension scientists and academics working in botany, biology, entomology, ecology, agriculture, horticulture, plant pathology, and the environmental sciences.

The papers contained in this book were presented at a NATO Advanced Research Workshop (ARW) held at Cape Sounion, Athens, Greece, 19-24 May, 1991. The twenty-eight more comprehensive papers represent the key subjects of the ARW covered by invited speakers. The thirty-four short papers pre sented in a research format are contributions of those invited to participate in the ARW. There was a total of 70 participants from 21 countries. The objectives of the ARW were as follows: to review current knowledge of biological control of plant diseases and plant parasitic nematodes, with emphasis on mechanisms at the molecular, cellular, organismal, and ecosystem level; to examine and expand on current concepts and synthesize new concepts; to identify and prioritize limitations in the use of biological control for plant diseases and nematodes and the scientific research needed to overcome these limitations; and to develop strategies for biological control through management of resident agents or introduction of natural or modified agents.

Biological management of diseases of crops is influenced by the nature of interactions between the pathogens and other organisms and the plants. Due to development of resistance in pathogens to fungicides and bactericides, determination of compatibility of biotic biocontrol agents with chemicals is essential for selecting strains of biocontrol agents (BCAs) showing resistance to chemicals to effectively restrict use of the chemicals. Microbial plant pathogens and the antagonists present in the soil and on the plant surfaces are influenced by various cultural practices. It is possible to reduce disease incidence and intensity by crop sanitation and using appropriate rotational crops. Application of physical techniques involving the use of heat, solarization and irradiation has potential to reduce the pathogen population or weaken the potential of pathogens present in the seed, planting materials and soil.

Plant diseases and changes in existing pathogens remain a constant threat to our forests, food, and fiber crops as well as landscape plants. However, many economically important pathosystems are largely unexplored and biologically relevant life stages of familiar systems remain poorly understood. In a multifaceted approach to plant pathogenic behavioral control, Sustainable Approaches to Controlling Plant Pathogenic Bacteria discusses the impact of plant pathogenic bacterial pathogenesis on scientific and economic levels. It introduces mechanisms, measuring tools, and controlling strategies you can use to meet the challenge of developing new and innovative ways to control plant diseases. The book covers many aspects of the activities of pathogenic bacteria that interact with plants. With chapters contributed by experts, the book focuses on: Pathogenesis Epidemiology Forecasting systems Control measures including diagnosis, quarantine, and eradication Adoption of agro-traditional practices Tools for the control of antibacterial polypeptides Nutrient supplements Metabolic substances from other organisms Mechanisms of siderophores Host resistances Quorum sensing and quenching Seed and foliar applications Impact of plant pathogens on scientific and economic levels The editors’ approach provides a broad perspective, including modern trends in ecology that consider plant pathogenic bacterial control from all angles. The discussions and reviews in the book cover a wide range of aspects of plant pathogenic bacterial pathogenicity, epidemiology, and impact on the food chain as well as strategies for control, which will help you develop sustainable methods for controlling plant diseases.

Biological disease management tactics have emerged as potential alternative to chemical application for containing crop diseases. Biotic and abiotic biological control agents (BCAs) have been demonstrated to be effective against diseases caused by microbial plant pathogens. Combination of biotic and abiotic agents leads to synergism and consequent improvement in the effectiveness of disease control. It is essential to assay the biocontrol potential of all isolates/species of fungal, bacterial and viral biocontrol agents by different techniques in vitro and under greenhouse and field conditions and to precisely identify and differentiate the most effective isolates from less effective ones by employing biological, immunological and nucleic acid-based assays.

Septoria leaf blotch has been the major disease of wheat in Britain and much of the rest of Europe. It has been reported that the disease causes serious yield losses to range from 31 to 53%. Mycosphaerella graminicola (anamorph: Septoria tritici) is the pathogen which causes Septoria leaf blotch. The disease can be controlled by various methods such as cultural practices, chemical control, using resistant varieties and biological control. In plant pathology, the term biological control leads to the introduction of microbial antagonists or host specific pathogens to suppress diseases and populations of one or more plant pathogens. This study investigated the microbial community on and within wheat leaves which can suppress Septoria leaf blotch by reducing the inoculum level of the causative pathogen M. graminicola. Plate count and DGGE analysis techniques were used to assess the microbial community. The changes in the microbial populations of healthy, senescent and M. graminicola infected i.e. diseased wheat leaves were investigated in vitro on agar plates using plate colony count method. It was found that method was successful in assessing both bacterial and fungal population sizes showing distinct colonies. DGGE is a rapid method which can analyze large number of samples simultaneously. The bands appearing in DGGE profile represent different species present in the microbial population. The DGGE technique was successfully used in this study to assess bacterial community. Bioinformatics tools have also played a vital role in this study for identifying bacterial and fungal species. A total of five bacterial species and five fungal species were identified by bioinformatics tools. The antagonistic abilities of identified bacterial and fungal species were tested against a Septoria isolate in vitro on dual culture PDA plates. Four microorganisms (Fusarium sp., Verticillium sp., Penicillium sp., Sporobolomyces sp. and Microbotryum sp.) in the dual cultures vary in their colony length, width, ratio of length and width and distance bwtween them. But after statistical analysis all the values are insignificant observations of dual culture plates indicated that the microorganisms might inhibit Septoria by competing for space. These microorganisms after testing might be good candidates for further in vivo testing of Septoria inhibition. A thorough knowledge of wheat leaf microbial communities is required for further use of biocontrol in the future.
