Contains 24 contributions and an additional six abstracts focusing on the use of biocontrol agents in agriculture. Sections address the need for enhanced biocontrol agents and strategies for enhancement; technologies for enhancing biocontrol agents; risks from enhanced biocontrol agents and their mitigation; and genetics and molecular biology of enhancing biocontrol agents. The abstracts address emerging biocontrols including valine excreting isolate of Pseudomonas syringae cv. tagetis exhibiting enhanced virulence against hounds tongue (Cynoglossum officinale); application of fungal polysaccharides in plant protection; and the predisposing of forest weeds by chemical and manual cutting treatments to enhance the efficacy of selected biocontrol agents.

The increased relevance given to life and food quality, and environment preservation must be balanced with the needs to produce enough food to sustain humanity. Food production without pest (weed, disease and insect) control is impossible. The environmental considerations as well as the evolution of pesticide resistances requires that chemical pest control be augmented and significantly supplanted by other procedures. Despite many promising results obtained using biological control agents, their utility is still quite limited, replacing only a small part of the market of chemical products. This is due to many reasons, such as difficulties to find new and suitable agents, technological limits in application, storage and formulation of organisms, environmental restrictions of application, costs of registering, producing and delivering biopesticides. The major reason though is that very few agents have the efficacy of traditional chemicals, yet typically costing more than chemical pesticides The advent of biotechnologies and molecular biology has opened new perspectives in using microrganisms in biocontrol, by allowing improvements in the properties of biocontrol agents and their delivery. The potential new risks associated with the introduction of new genes and organisms must be adequately accessed, which is a recurring motif throughout the proposed program. It is only if these issues are fully and transparently addressed can the necessary lines of communication be opened to the public. The book preserves, as the NATO workshop which generated it, a subject-oriented structure that could attract the interest of the scientific community working with different biological agents (fungi, bacteria, virus, nematodes, insects), on different targets (pathogens, insects, weeds). This multi-disciplinary approach (molecular biology, formulation, genetics, risk assessment, new technology, biochemistry, physiology) is necessary to design biocontrol agents with improved efficacy. It is hoped that by investing in this type of multi-disciplinary area that research will lead to new and improved agents that will be ready for use at about the time when the food supply becomes limiting, or when resistance to the few remaining conventional pesticides becomes a major limitation.
