Crop Health Management for Food Safety and Agroecosystem Health in Developing Countries Organizer: Irmgard Hoeschle-Zeledon, SP-IPM, c/o International Institute of Tropical Agriculture, Ibadan, Nigeria Section: IPM-Biocontrol-Plant Disease Management Sponsoring Committee: IPM-Biocontrol In efforts to reduce hunger and poverty, food production often comes first; food quality and environmental as well as human health second. To treat healthy food as a luxury means ignoring human and livestock health, economic development, and trade opportunities. The special session presents new IPM technologies to assist farmers in developing countries to manage mycotoxins and keep pesticide residues below levels set by trade regulations based on health concerns. Pesticide residues are a result of pesticide overuse or misuse, leading to the loss of the self-regulating forces in the agroecosystem. A shift from research addressing crop production, plant breeding, or soil fertility as separate entities to crop health management as an integrated approach, combining the contributions of IPM, plant breeding, and soil fertility research to improve crop and human health and agroecosystem resilience is needed. • Disseminate good agricultural practices in vegetable production for better human and agroecosystem health.

The Developing Crisis, International Movement of Insects and Pathogens in Commercial Trade Organizers: Thomas Harrington, Iowa State University, Ames, IA, U.S.A.; James Steadman, University of Nebraska, Lincoln, NE, U.S.A. Section: Emerging Pests/Invasive Species Sponsoring Committees: APS Forest Pathology; APS Public Policy Board; APS Regulations; APS Office of International Programs; IAPPS Financial Sponsors: The Nature Conservancy; American Seed Trade Association; Pioneer Hybrid International; Monsanto This special session brings attention to the growing crisis in the movement of insects and pathogens around the world through commercial trade. As trade grows, so grows the introductions of pests that threaten agriculture and natural resources. In some areas, we lack sufficient national and international regulations, but for others, current regulations may not be science-based or may pose serious impediments to trade. We begin with a case study of Hawaiian problems with alien species. Potential for unwanted introductions in commercial seed trade will be contrasted with the need for better international standards. Pitfalls in developing regulations to lessen the risk of introductions of insects and pathogens in woody material will be presented. Finally, we present the flaws in international protocols for preventing entry and spread of pathogens via “plants for planting”. • You think you have problems? The crisis in Hawaii. C. MARTIN, Pacific Cooperative Studies Unit, Coordinating Group on Alien Pest Species, Honolulu, HI, U.S.A. • Real and imagined problems in movement of plant pathogens in international seed trade. R.

Disease Complex Between Nematodes and Other Plant Pathogens Organizer: Koon-Hui Wang, University of Hawaii, Honolulu, HI, U.S.A. Section: Plant Pathology-Diseases of Plants Sponsoring Committees: Nematology; Soil Microbiology and Root Diseases Plant-parasitic nematodes are often treated as hidden pests, but in reality their damaging impact could be catastrophic. Some examples of devastating nematode damages are plant disease complexes that involve plant-parasitic nematodes as a vector or having nematodes that intensify the damage. In other cases, nematodes are transmitted by an insect vector that could result in a wide-scale epidemic disease. This special session will showcase close collaboration between nematologists, plant patholgists, and entomologists to “implement change for plant protection”. 9

Invasions of new insect vector species and biotypes, shifting agricultural practices, and globalization of agricultural and horticultural products are contributing to the emergence and/or reemergence of numerous viral diseases. Vector-borne viruses are major constraints to food production and security in tropical countries. A broad knowledge of virus and vector biology and epidemiology and of interactions of viruses with their vectors and ecosystems are needed to design and implement successful management strategies. Vectors and viruses transcend geographic and national boundaries, necessitating multidisciplinary, system-wide, and holistic approaches to eco-friendly, sustainable management strategies for plant virus diseases. Invited speakers will 15


present overviews of vector and virus disease management strategies. Case studies with different perspectives and experiences in designing and implementing management strategies will give insight into IPM for management of insect-transmitted virus diseases globally. • The role of epidemiology in the management of insect-transmitted viruses—A tropical perspective.

Phytopathological Phreakonomics

Organizer: Janna Beckerman, Purdue University, West Lafayette, IN, U.S.A. Section: Plant Pathology-Diseases of Plants The book, Freakonomics: A Rogue Economist Explores the Hidden Side of Everything, written by Steven Levitt, a University of Chicago economist, and Stephen J. Dubner, a New York Times journalist, applies economic theory to a diversity of cultural phenomena. It is often described as pop culture meets and is decon-structed by economics. What would happen at the intersection of pop culture, economics, and plant pathology? The objective of this special session is to apply three cornerstones of the book to plant pathology. These cornerstones are i) the conventional wisdom is often wrong; ii) experts use their information to their own advantage; and iii) dramatic effects often have distant even subtle causes. • Phytopathological phreakonomics and organic agriculture—An introduction to economics and the deconstruction of phytopathology.

Plant Protection and Food Security in a Changing World Organizers: Jenifer Huang McBeath, University of Alaska Fairbanks, Agricultural and Forestry Experiment Station, Fairbanks, AK, U.S.A.; Lewis Ziska, USDA-ARS, Crop Systems and Global Change, Beltsville, MD, U.S.A. Section: Weed Science Sponsoring Committee: IAPPS Organization Committee Both plant protection and food security are strongly influenced by changes in the global environment. The effects of climate change are greater in polar regions than elsewhere and are particularly noticeable in the far north. Decadal increases in temperature and ocean warming have resulted in rapid glacial melt and increased storm surges on the coast; melting sea ice increasingly opens the arctic to marine transportation. Other changes caused by warming include fluctuating precipitation and wind patterns and rising ground temperatures, which in turn affect crop diversity as well as transmission, survival, and dominance of invasive pathogens, arthropods, and weeds in the environment. In addition, technology advancement often alters the environment surrounding host plants. The many dimensions of climate change will have significant impacts on plant protection and food security, which are explored in this special session. • New challenges for plant protection under conditions of climate change.

What Else is There? New Genes, Metabolites, and Regulatory Pathways Involved in Biocontrol by Bacteria Organizer: Brian McSpadden Gardener, The Ohio State University-OARDC, Wooster, OH, U.S.A. Section: Plant Pathology-Molecular/Cellular/Plant-Microbe Interactions Sponsoring Committees: APS Biological Control; APS Bacteriology The rapid adoption of high-throughput sequencing has resulted in a large number of genome sequencing efforts of diverse biocontrol bacteria. Functional analysis follows with site-directed mutation of interesting candidates and either metabolomic and/or bioassays to characterize how such genes affect interactions with plant hosts and targeted pathogens. Recently, work in several laboratories has lead to the discovery of new genes, metabolites, and regulatory pathways that will transform our understanding of how single strains affect plant health. This special session will provide an opportunity for those most recent discoveries to be presented and discussed in the context of our rapidly changing paradigm of biocontrol. • Revelations from multiway comparisons of genomes from multiple pseudomonad biocontrol agents.

Wheat Blast—A Potential Threat to Global Wheat Production Organizer: Gary Peterson, USDA ARS Foreign Disease-Weed Science Research Unit, Fort Detrick, MD, U.S.A. Section: Emerging Pests/Invasive Species Sponsoring Committees: APS Regulatory Plant Pathology; APS Emerging Diseases and Pathogens Financial Sponsor: British Society for Plant Pathology Wheat blast, caused by a pathotype of the pathogen Magnaporthe grisea is an emerging disease in temperate regions in South America. Originally identified in Parana, Brazil, in 1985, it has since established in 90% of Brazil’s wheat production areas with field losses of 5 to 100% reported. In 2009, Brazil reported disease losses of 30% nationally. Bolivia removed 60% of its fields from production and Paraguay reported losses of 30 to 40%. In 2010, wheat blast was observed in production fields in Argentina. Rain at flowering and high temperatures favor severe disease loss. No wheat cultivars have been identified as resistant to all isolates of wheat blast. Foliar symptoms are absent in commercial fields and the source of seasonal inoculum has not been clearly identified. Foliar applications of fungicides have proven to be ineffective during favorable disease years. The aim of this special session is to provide information on the history of the disease, a summary of current research and management approaches, and the possible implications of international spread. • Mechanisms of resistance and chemical control of wheat blast.
