Insect pathogens are often overlooked in the development of IPM but are important natural enemies of pest insects that can act in a density-dependent manner to reduce outbreak populations. They can often be cultured artificially and applied as biopesticides. This special session will examine the way microbial agents are incorporated into pest management systems through in situ management, classical biocontrol release, or inundative control. Specific examples of successful integration of microbes will be provided as case studies from specific countries/regions, including Brazil, China, and Australasia. An industry view of microbial biocontrol will be included and regulatory issues covering the use of pathogenic microbes will be discussed. 8:30 a.m. A bioprotection strategy for greater integration of beneficial microbes into IPM.

The family Closteroviridae comprises genera with monopartite genomes, Closterovirus and Ampelovirus, and with bipartite and tripartite genomes, Crinivirus. They are semipersistently transmitted by aphids (closteroviruses), whiteflies (criniviruses), or mealybugs/scale insects (ampeloviruses) and represent the most complex plant viruses infecting a broad range of agriculturally important crops. Closteroviruses in the genera Closterovirus and Crinivirus revealed exceptionally complex genome organization and expression strategies unique to the viruses in the family Closteroviridae. By contrast, much less is known about the molecular biology of closteroviruses in the genus Ampelovirus. The special session will provide a comprehensive overview of the current status of the biology and molecular biology of different members of the family Closteroviridae. 8:30 a.m. Current status of the molecular biology of closteroviruses.

Quality planting materials are essential for increasing agricultural productivity, meeting growing food demands and providing higher yields of healthy and nutritious crops. Quality seeds and planting materials provide plants an inherit mechanism for combating insect pests, plant diseases and weeds, thereby equipping them with the essentials needed to survive in less than optimum environments and climates. The availability of quality planting materials is a major constraint for food production in many developing countries. Speakers will share their perspectives on sustainable solutions for quality seed production, seed systems and distribution in developing nations.

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.

This 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 of trade, we need more stringent national and international regulations, but in others, current regulations 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. There will be presentations on introductions of insects and pathogens in woody packing material and flaws in international protocols for preventing entry and spread of pathogens via “plants for planting”. Efforts to develop better public policies to reduce risks will be discussed.

The emergence of new generation DNA sequencing technology has enabled comparative genomic analysis of numerous related fungal species and even different strains of the same fungal species. These studies have led to breakthroughs in predictions of gene structure and function, identification of species- and lineage-specific sequences, as well as discovery of the dynamics of pathogenic adaptation and whole-genome evolution. This special session will summarize recent findings from individual comparative genomics projects as well as attempt to find common themes of evolution for pathogenicity among the diverse pathosystems represented. In addition, the special session will explore an application of next generation DNA sequencing technology for analysis of genes from plant-pathogenic fungi expressed in planta.

Development of biological pest control agents and its harmonization with chemical pesticides becomes important in East Asia, where heavy pest pressures constantly exist due to severe weather conditions and therefore the IPM system has not accepted by many farmers for years. However, recently several unique and outstanding biological pesticides have been investigated in the area. In the special session, seven speakers, who are represented in each crop protection-related scientific society in East Asian countries will introduce the up-to-date information under the scope of the development of biological pest control agents as well as conventional chemical pesticides in this area. The information will surely give useful suggestions to the similar areas where the introduction of IPM system would be difficult.

The management of pests through integrated pest management (IPM) is critical to developing and maintaining sustainable agricultural production systems. To achieve this challenging pest management goal, IPM practitioners must possess specialized knowledge about the pests, the production system involved, and their interactions. This increased requirement for IPM expertise occurs at all levels of agriculture, from subsistence farming through high-input and technologically driven agricultural systems found in most developed countries. This special session will explore the educational requirements for effective IPM at these various production levels and describe the diverse types of IPM education and training opportunities that are available.

The dramatic increase in the infestation of weeds that invade from other countries is alarming. The “new comers” cross borders, affect biodiversity, and infest millions of hectares all over the world. Some of the invasive weeds are allergenic and may cause significant losses of working days. It was estimated the 35% of the European and U.S. population are sensitive to Ambrosia pollen. This special session will discuss the processes involved in plant material movement across borders, their establishment, and propose options for harmonized and sustainable management.

Resistance of plant pathogens to fungicides is one of the most important issues for plant disease management in North America. Resistance negatively impacts our ability to control diseases and has significant economic consequences. To successfully manage resistance, reliable and accurate methods for detection and characterization of resistance are essential. Topics will include an analysis of critical mistakes made in resistance assessment, statistical considerations for studies, and a review of in vitro, in vivo, and molecular methods for detecting and characterizing fungicide resistance with emphasis on the most economically important pathogens and fungicide groups.

Viruses causing economically important plant diseases are often transmitted by specific insect vectors that may also be pests of the crop. 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 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.

This special session will focus on -omics approaches for comparing strategies with which phytobacteria and also human enteric pathogens (like Salmonella, E. coli, or Serratia) colonize and persist within plant tissues. Given all the recent outbreaks of vegetable-borne gastroenteritis, there is a real interest in understanding how human pathogens interact with plants and also in learning how to deal with human pathogens from the perspective of a plant pathologist.

Parasitic weeds such as witchweed (Striga spp.), broomrape (Orobanche spp.), and dodder (Cuscuta spp.) are the main parasitic weeds that infest all major crops, monocots and dicots, all over the world. Witchweed infestation in maize, sorghum, and millet causes hunger in more than 100 million people in Africa. Broomrape parasitizes legume crops all over the Mediterranean region and sunflowers all over Eastern Europe and the Mideast. Field dodder is a cosmopolitan pest in alfalfa, cucurbits, and vegetable crops such as carrots.

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 deconstructed 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.

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.

Sizeable portions of the continents of Africa, Asia, Australia and South America lie within the geographically defined tropics. Wild land or natural forests and managed or plantation forests are highly valued for timber production, watershed protection, wildlife habitat, global warming mitigation, and cultural connections. Diseases of trees in these settings threaten the health and survival of Acacia, Casaurina and Eucalytptus species, in particular. The biology, epidemiology and development of disease resistance for management will be discussed for major pathogens of these and other taxa.

The use of biotechnology in crop improvement has the potential to dramatically impact the sustainability of agriculture production worldwide. However, there has been reluctance to accept many crops with biotech traits—especially disease resistance traits. This special session will focus on the current status of GMO technology and the “translational” aspect of this technology. This special session will provide a retrospective look at the way genetic modification has benefitted plant protection and lessons that have been learned from previous attempts to use biotechnology to advance breeding for resistance to disease. In addition, the special session will provide an ethical view of the use of biotechnology in agriculture from a nonscientist’s perspective as well as a scientist’s view of how to best communicate the benefits of using biotechnology to provide a sustainable supply of food.

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.

Wheat blast, caused by Magnaporthe grisea, is an emerging disease in temperate regions of South America. Identified in Parana, Brazil, in 1985, it has since established in 90% of Brazil’s production areas with losses of 5 to 100% reported. Similar losses were reported in Bolivia and Paraguay. The disease has recently spread to Argentina. Rain at flowering and high temperatures favor sever disease loss. No wheat cultivators have been identified as resistant to all isolates of wheat blast. Foliar symptoms are absent and the source of seasonal inoculum has not been clearly identified. Foliar applications of fungicides have been 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.

Crop loss is the raison d’être of plant pathology and plant protection. We quote crop loss estimates and assessments with little forethought every time we seek to justify our positions, careers, grant proposals, and daily activities. Yet few of us really understand the complexity and diversity of crop loss assessments or possess the skills to either evaluate the estimates quoted by others or generate sophisticated hierarchical estimates for special purposes. A multidimensional approach to crop loss assessment and its impact on local, national, and global levels will be discussed.
