A number of new viruses/diseases have been recently reported from various economic crops. This session will address the emergence of new viruses in these crops and will discuss their possible origins (either by emergence from native vegetation or their introduction with imported planting material). The ultimate goal is to get a better understanding of where these new viruses are coming from in order to design and impose appropriate control and selection measures to maintain healthy crops.

Legislation restricting pesticide use on turfgrass has emerged on a limited scale in the United States. However, pesticide bans on turfgrass have been enacted throughout Canada. This session will focus on issues inspiring legislation and on challenges of managing turfgrass disease without the judicious use of pesticides. Canadian and U.S. industry leaders and scientists will share current management approaches and discuss future potential strategies for controlling turf disease without pesticides.

Destructive tree diseases associated with ambrosia and bark beetles have appeared recently in the United States. They threaten native and commercial tree species and typically involve non-coevolved encounters between host trees, the beetles, and their associated phytopathogens. We refer to these developments as Black Swan events in that they are unpredictable and have extreme impacts on the landscape. The proposed speakers will address the significant threats that are posed by these diseases.

In 1996, Congress passed legislation for EPA to screen pesticides and drinking water contaminate chemicals for their potential to interact with the endocrine systems of humans and wildlife. This session will address the status of the EPA Endocrine Disruptor Screening Program and its relationship for plant disease control. Presenters will address the legislative history, background and status of the program, experience from industry, and future for plant disease control.

Some of the most important bacterial diseases are especially difficult to study, detect, and control. Insect transmission, long latency periods, and lack of chemical controls and natural genetic resistance can thwart efforts toward plant protection against diseases such as citrus greening, zebra chip, and Pierce’s disease. This session aims to highlight some of the innovative methods being developed toward the genetic and biological control of these pathogens.

Biopesticide use in plant disease management has grown steadily over the past 20 years. Still, many growers, crop consultants, and extension pathologists are reluctant to include registered biopesticides in integrated disease management programs. The goal of this session is to provide practical insights into the evolution of the U.S. biopesticide industry and the strengths, limitations, and real-world applications of registered biopesticides from academic, industry, and grower perspectives.

The family Potyviridae comprises ~30% of all known plant viruses and affects economically important food crops worldwide. In recent years, rapid progress has been made in defining potyviral gene functions, identifying potyviral determinants responsible for overcoming host resistance, and understanding mechanisms of resistance to potyviruses. These studies will potentially aid in identifying key steps in pathosystems for the development of new disease prevention and mitigation strategies.

The multiple dimensions of food security imply that interdisciplinary, multisectoral approaches are required to address it. Each dimension may be weakened or strengthened by a number of factors and may act in a transient or chronic manner. This session will address the effects of plant diseases and pathogens on the four dimensions of food security—food supply, physical access to food, economic access to food, and food utilization—and will elaborate on the challenges we face as well as possible solutions.

Dothideomycete fungal pathogens infect many crops, but genetic regulation of virulence remains poorly understood. Recent advances in genetic analysis and functional genomics, combined with an elucidation of the biological parameters underlying host-pathogen interactions, have uncovered novel mechanisms of pathogenesis. This session will address key questions in fungal biology and genetics that provide fresh perspectives on fundamental processes governing the host recognition and pathogen virulence.

The phytobiome is defined as the entire microbial community in, on and adjacent to plants. The capacity to study the phytobiome as a system will reveal how the associated microbial community influences, or is influenced by, the plant. These fundamental discoveries can be applied to improve crop productivity, address environmental challenges, and assure food safety. APS PPB has launched the Phytobiomes Initiative to gain a comprehensive understanding of phytobiomes and the capacity for their optimization by 2025. The goal of this symposium is to illustrate why funding investments in phytobiome approaches are critical by highlighting what we have not been able to learn by looking at individual organisms and by revealing what can be learned when microbiomes are studied as a system.
