Biological Control in Agricultural IPM Systems covers the proceedings of the 1984 symposium on Biological Control in Agricultural IPM Systems, held in the Citrus Research and Education Center of the University of Florida at Lake Alfred. The symposium summarizes the status and practical use of biological control in agricultural integrated pest management (IPM) systems in the United States. The book is organized into seven parts encompassing 31 chapters that cover the biological control of arthropods, weeds, plant pathogens, and nematodes. After briefly discussing the status and issues of biological control in IPM, the book deals with the basic principles of IPM programs and their related costs, risks, and benefits in biological control. The text also describes the compatibility of plant resistance with biological control of arthropods and the chemical mediated host or prey selection behaviors of entomophagous insects attacking herbivorous insect pests. It explains the development of microbial insecticides; the genetic improvement of insect pathogens; the use of entomogenous nematodes in cryptic and soil habitats; and the techniques for integrating the influences of natural enemies into models of crop/pest systems. The fourth part of the book focuses on the biological control of weeds. The following part considers the general concepts relating to the unique characteristics of plant diseases affecting aerial plant parts. This part also examines the biological control of soil plant pathogens in IPM systems and the use of soilborne viruses, bacteriocins, and hypovirulent strains of fungi as biological control agents. The concluding parts describe the biological control of nematodes and the status and limits to biological control in selected commodity IPM systems, such as citrus, grapes, alfalfa, cotton, and soybean. Entomologists, plant pathologists, weed scientists, nematologists, toxicologists, and economists will find this book invaluable.

There is increasing interest in the use of fungi for the control of pests, weeds and diseases. This book brings together perspectives from pathology, ecology, genetics, physiology, production technology, to address the use of fungi as biological control agents.

The offered volume intends to review the biological control theme of phytonematodes from several prospects: ecological; applicative as well as commercial state of the art; understanding the mode-of-action of various biocontrol systems; interaction between the plant host, nematodes’ surface and microorganism’s; candidates for biocontrol; extrapolation of the wide knowledge existed in another systems for understanding biocontrol processes: C. elegans as a model and lessons from other natural systems; and exploiting advanced genomic tools to promote understanding biocontrol processes and thereafter improve specific biological control agents.

During the 20th century, agriculture underwent many unsustainable changes for the sake of greater food production. Today, the effects of climate change are becoming ever more apparent and the global population continues to grow, placing additional pressures on agricultural systems. For this reason, it is vital to turn international agriculture towards a sustainable future capable of providing healthy, bountiful foods by using methods that preserve and reconstruct the balance of natural ecosystems. Fungi are an underappreciated, underutilized group of organisms with massive potential to aid in the production of healthy food and other products while also increasing the sustainability of agricultural systems. Mycoagroecology: Integrating Fungi into Agroecosystems lays the foundations for integrated fungal-agricultural understanding and management, the proposed practice of “mycoagroecology”. Suitable for students and professionals of multiple disciplines, this text includes nine introductory chapters that create a firm foundation in ecosystem functioning, evolution and population dynamics, fungal biology, principles of crop breeding and pest management, basic economics of agriculture, and the history of agricultural development during the 20th century. The latter half of the text is application-oriented, integrating the knowledge from the introductory chapters to help readers understand more deeply the various roles of fungi in natural and agricultural systems: PARTNERS: This text explores known benefits of wild plant-fungal mutualisms, and how to foster and maintain these relationships in a productive agricultural setting. PESTS AND PEST CONTROL AGENTS: This text acknowledges the historical and continuing role of agriculturally significant fungal pathogens, surveying modern chemical, biotechnological, and cultural methods of controlling them and other pests. However, this book also emphasizes the strong potential of beneficial fungi to biologically control fungal, insect, and other pests. PRODUCTS: This text covers not just isolated production of mushrooms on specialized farms but also the potential for co-cropping mushrooms in existing plant-based farms, making farm systems more self-sustaining while adding valuable and nutritious new products. An extensive chapter is also devoted to the many historical and forward-facing uses of fungi in food preservation and processing.

This guide presents new and promising, alternative methods for controlling fungal, viral, and bacterial diseases of plants--methods which limit and, in some cases, eliminate the use of biocides. Considers three major concepts of disease control including biological control systems, biochemical and physiological manipulations in plants, and the use of molecular biology and the potential of genetic engineering. Presents updated findings together with authors' views and speculations on plant disease control.

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.

This book, prepared by participants of the European network COST ACTION 810 (1989-93) is the outcome of a meeting held in Switzerland (Einsiedeln, September 29 to October 2, 1993) on the "Impact of arbuscular mycorrhizas on sustainable agriculture and natural ecosystems". COST(Cooperation Scientifique et Technique) Networks were created in 1971 by the Commission of European Communities, and later enlarged to include non-European Member States, to promote pre-competitive scientific and technical research in fields of common interest. During the eighties, COST ACTIONS were launched in bio technological fields, including the network on arbuscular mycorrhizas. Arbuscular mycorrhizas are a universally found symbiosis between plants and certain soil fungi and essential components of soil-plant systems. They act as a major inter face by influencing or regulating resource allocation between abiotic and biotic components of the soil-plant system. Arbuscular mycorrhizas are involved in many key ecosystem processes including nutrient cycling and conservation of soil struc ture, and have been shown to improve plant health through increased protection against abiotic and biotic stresses. Sustainability can be defined as the successful management of resources to satisfy changing human needs while maintaining or enhancing the quality of the environ ment and conserving resources. Increasing environmental degradation and instability, due to anthropogenic activities and in particular the increasing fragility of the soil resource, has led to an increased awareness of the need to develop practices resulting in more sustainable natural and agroecosystems.
