IUPAC International Congresses of Pesticide Chemistry have served as the premier forum for international exchange of scientific information among pesticide chemists since 1967. They are held every four years, and IUPAC (Interna-tional Union of Pure and Applied Chemistry) sponsorship is arranged by Division of Chemistry and Environment’s Advi-sory Committee on Crop Protection Chemistry. Congress sites are based on proposals received from national chemistry organizations, which, when selected, take the lead in meeting organization.

Co-organizers for this Congress, Kenneth Racke, Dow Agrosciences, and Laura McConnell, Bayer CropScience, provided excellent leadership for a multitude of volunteers to bring together the various factors that made for a successful meeting. The 13th Congress merged the traditional strengths (oral and award symposia) of the Agrochemicals Division (AGRO) with the historic design of IUPAC Congresses (inter-active poster sessions, discussions, workshops and plenary lectures). Sponsored lunchtime and dinner seminars, a program innovation that began at the Kobe IUPAC Congress in 2006, provided a wide range of innovative topics that promoted discussions. The 13th Congress had 1216 partic-ipants representing 53 countries (52% were from the U.S.) Over 1000 abstracts (for poster and oral presentations) were included in the final program, which was comprised of 46 technical symposia of invited lecturers, poster sessions and interactive panel discussions.

Main topics

The core of the meeting was comprised of nine major topics, each organized into symposia with oral and poster presen-tations and an interactive session. Each topic was organized by an international team led by a U.S. coordinator, and the focus of individual symposia include within the main topics are summarized below:

Emerging Issues and Challenges, Cheryl Cleveland, BASF

Sustainability: A Greener Revolution: This symposium focused on developing definitions of what is meant by sustain-able agriculture and how this fits in the context of produc-ing food, fiber and fuel. Methods were emphasized that allow growers to evaluate production decisions in order to compare sustainability performance.Agriculture’s Response to Climate Change and Population Growth: Presentations covered a broad scope of topics rang-ing from adaptive strategies to detailed technical aspects in developing novel chemicals, improving agricultural resilience and improving efficacy of nitrogen fertilizer use. Pollinator Health: Risk Assessment and Sustainable Manage-ment: This symposium took a holistic perspective on polli-nator risk, encompassing not only pesticides but pathogenic viruses, bacteria, fungi and parasitic mites, along with nutri-tional deficiency and colony management practices.Global Food Production and Food Security: Food security was discussed related to production, access and stability. Although nature is not readily controlled, attention can be given to such aspects as modern biotechnology to address pest/disease resistance, water efficiency, draught tolerance, improved nitrogen uptake and utilization, growth in agricul-turally poor soils, resistance to heat, cold, flooding and other abiotic stresses.

Agricultural Biotechnology, Jennifer Anderson, DuPont Pioneer

Communication and harmonization needs were also discussed.Advances in the Risk Assessment of RNAi-based Technolo-gies: RNA interference (RNAi) is an emerging tool in the field of agricultural biotechnology. This session highlighted techni-cal advances in the field and provided an overview of regula-tory considerations for RNAi-based traits. Advances in Development, Characterization and Regulation of Genetically Modified Crops: Development of new traits, merits of global harmonization, data transportability and analytical methodologies to support detection, characteriza-tion, and risk assessment were highlighted.Analytical Challenges and Considerations for Protein and RNAi-based Technologies: Focus was on analytical methods and screening tools that are currently under development to assist the characterization of protein and RNAi-based traits with discussions on challenges associated with optimization and validation.

Challenges Associated with Global Adoption: This sympo-sium included presentations and discussion on many issues facing acceptance and adoption such as public perception, regulatory requirements, lack of experience with regulation and governance of GM crops and lack of familiarity with regulatory requirements for related research. Contributions to Sustainable Agriculture and Food Security: Presenters emphasized that genetically modified crops offer great potential for promoting and improving sustainable agriculture. Methodology to assess these contributions was discussed.

Discovery and Synthesis, Thomas Stevenson, DuPont Crop Protection

New Approaches to the Discovery of Crop Protection Prod-ucts: This session included presentations on novel approaches to development of pest management tools such as natural products and how chemistry from the pharmaceutical indus-try can be leveraged to discover new crop protection lead structures.New Chemistries Targeting Insect Control: New insecticides, value of high-throughput screening, new screening methods and determination of potential targets contributed to this session.New Chemistries Targeting Plant Disease Control: This session highlighted discovery of new fungicidal products and lead compounds to combat resistance and fulfill unmet grower needs. New Chemistries Targeting Weed Control: Presentations focused on the fact that weed resistance to known modes of herbicidal action has created an unprecedented need for new herbicide products.

Ecosystem and Human Exposure and Risk Assessment, Aldos Barefoot, DuPont Crop Protection

Agroecosystems: Sustaining Biodiversity and Key Ecosystem Services: Through a series of case studies, this session exam-ined how chemistry may benefit both agriculture and nature with respect to the interaction of agricultural ecosystems and biodiversity, and how the potential for negative effects on the services provided by agricultural practices can be mitigated.Use of Ecological Models in Regulatory Risk Assessment: Recent activity in development of ecological models for use in regulatory risk assessments of pesticides and other chemicals was highlighted.Trophic Transfer, Metabolism, and Risks in the Food Web: This session focused on the science behind classifications related to chemical persistence in various phases of the envi-ronment, bioavailability of these chemicals and how the envi-ronmental chemistry of pesticides can be used to understand risks better. Advances in Exposure Assessment for Characterizing Human and Ecological Risks: Various advances in risk assessment were emphasized including research on metabolic pathways, metabolite residues, environmental fate and availability and exposure assessment tools.Advancing Surface and Ground Water Exposure and Risk Assessments by Optimized Monitoring and Modeling: This session explored the latest improvements in monitoring


O u t l o o k s o n Pe s t M a n age m e n t – O c t o b e r 2 0 1 4 3


programs and in techniques for validating and extending the use of monitoring results with predictive modeling.Implementing a Risk Paradigm for Pesticide Use Decisions in the Real World: Presenters illustrated the manner in which decisions on protection goals, effects testing and exposure assessments affect risk assessments and pesticide regulatory evaluations around the world.Global Approaches to Assessment of Bystander and Agricul-tural Worker Exposure and Risk: Presenters covered topics that ranged from how the risk assessment process is develop-ing in Brazil, Peru, Colombia, India and South Korea to the challenges faced in Australia in accessing the best available exposure data in an agricultural market whose size does not justify the costs of conducting costly exposure studies domes-tically.

Environmental Fate and Metabolism, Amy Ritter, Waterborne Environmental

Agrochemicals in Urban Environments: Presentations included studies to determine presence and behavior of pesticides in urban/suburban environments, modeling of movement, regu-latory assessments, effects of these chemicals in the environ-ment, effective mitigation measures and residues entering and leaving publically owned treatment works-sewage treatment systems.Metabolism and Mitigation of Agricultural Chemicals and Pollutants: Focus in this session was on environmental buff-ers, bioremediation the efficiency and usefulness of mitigation and remediation (soil and abiotic) in reduction of pollutants.Sampling Methods and Analysis of Agricultural Chemicals and Pollutants: Limitations in methodology, appropriate extraction methodology, standardization of extraction meth-ods, questions of bioavailability of non-extractable residues and how samplers can work with analytical labs were topics included in this session.Pesticide Efficacy, Translocation and Metabolism in Plants and Animals: This was an interactive poster discussion session addressing such topics as relevance of bound residue char-acterization, unextractable residues in plant metabolism, and roles of high resolution mass spectrometry and of 1D and 2D proton NMR spectroscopy.Measuring and Modeling Pesticide Fate and Transport: A focus was on the relationship of results from modeling and measurement of pesticide residues in the environment with toxicity data in risk assessment. Data from of various models and monitoring data were presented as were evaluation systems for specific cropping and geological sites.Sediment Partition and Bioavailability: This symposium included methods for estimating pore water concentrations and other assessment related topics, variability in partitioning due to organic matter characteristics, bioavailability of chemi-cals and the relationship of hydrophobic chemicals with fine particles in depositional areas.Atmospheric Emissions and Mitigation: Presentations high-lighted measuring and predicting the fate and transport of pesticides in soil as well as developing methods to measure and control atmospheric emissions. This symposium included the AGRO Innovation Award, won by Dr. Scott Yates (please see under AWARDS).

New Insights in Pesticide-Soil Processes Leading to More Realistic Exposure Assessment: Experiences with existing guidance regarding experimental setups, derivation of param-eters as well as implementation of higher tier processes in the exposure assessment of pesticides was presented.Fate, Effects and Risks of Nanopesticides: A number of ques-tions relevant to the topic were addressed. These included definitions and regulatory needs/considerations of nanopes-ticides, possible differences between nano- and conventional pesticides and guiding principles for an ecological risk frame-work for nanopesticides. Scientific and Regulatory Aspects of Chirality in Agro-chemicals: This session concluded that overall differences in degradation behavior and toxicological profiles of isomers can occur, but researchers need to consider what degree of difference is important and whether that difference is gener-ally covered by currently available pesticide safety data on mixtures.Improved and Novel Methods of Estimating Pesticide Degra-dation Patterns and Rates: Presentations examined improve-ments in methods for data development and modeling of pesticide degradation pathways, patterns and rates in soil and aquatic environments and how these can be incorporated into models.Handling of Mixtures in the Environment and Ecologi-cal Implications: Various factors of concern were presented including possible alteration of residues in the environment, whether the risk assessment process should be altered for mixtures, and how potential effects of mixtures should be measured.

Formulation and Application, Erdal Ozkan, Ohio State University

Technologies for Sustainable Crop Protection: An important aspect of this session was to get together those involved in formulation of agrochemicals with those involved and inter-ested in application of agrochemicals. Significant time was set aside for networking and for meaningful discussion on the topics.

Mode of Action and Resistance Management, Stephen Duke, USDA-ARS

ACS International Award for Research in Agrochemicals: A full day symposium honored Dr. Ralf Nauen (please see under AWARDS), recognizing the important and sustained contributions he has made to understanding insecticide modes of action and the role they play in resistance. Presentations covered not only new studies on the molecular mechanisms by which insecticides and acaricides control insects as well as mites and how genetic changes can lead to resistance, but also extended this knowledge to development of resistance management strategies for both insecticides and genetically modified crops with insect resistance traits. Herbicides: This symposium emphasized the major crisis in weed management in glyphosate-resistant crops. A strong point was made that reduction of selection pressure through diversity in weed management is necessary to prolong the util-ity of valuable herbicides and herbicide-resistant crops.




Insecticides: A variety of topics included novel insecticide target sites, control/management of specific insects, use of molecular modeling to identify insecticide binding sites, RNAi techniques to validate the role of over-expressed genes in resistance, novel high-throughput techniques to evaluate target sites and various resistance mechanisms in a variety of insect pests.Fungicides: Focus was on new modes of action, new prod-ucts, molecular mechanisms of resistance, new approaches to induce resistance to diseases in plants, use of biologicals as tools in resistance management and development/implemen-tation of resistance management strategies.

Residues in Food and Feed, Mike Krolski, Bayer CropScience

Taking Advantage of Advanced Analytical Tools: This sympo-sium presented examples of how state-of-the-art analytical tools provide advantageous new techniques for analysis of pesticide residues and similar application. Perspectives were given from industry, academia and federal as well as state governments.Progress in Global Harmonization of MRLs and Workshop: Presentations from international organizations as well as different regions emphasized the importance of harmoniza-tion of MRLs, which will allow free trade, a key element ensuring safe and affordable food around the globe. A work-shop reflecting viewpoints of different stakeholders involved in global MRL harmonization was summarized and discussed. Going from Macro to Micro: the Future of Sample Process-ing in Residue Analytical Methods: Focus was on the critical, but often overlooked, topic of sample processing for residue analysis. Micro-technologies provide innovative tools, but proper sample processing to obtain representative subsamples is a key to success in pesticide residue analysis. A main conclu-sion was that micro-technology in residue analysis should be evaluated for a given application to demonstrate acceptable performance before applying the protocol in practice. Monitoring Results and Dietary Risk Assessment Implica-tions: Developments in scientific and regulatory arenas were discussed with elaborations on benefits to all involved that result from approaches to reporting, interpretation and use of the data.

Stewardship, Regulation, and Outreach, Jeffrey Jenkins, Oregon State University

International Trade, Food Safety and GAP (good agricultural practices): This symposium focused on human health risk related to pesticides ranging from the farm gate to the table with the goal of establishing a common understanding of how pesticide use practices are related to international trade, national food safety and food security objectives.Common Global Goals in Pesticide Stewardship: Presenta-tions were made on practices and policies that have been successfully used around the world to improve pesticide stewardship.

Pre-congress symposiaPrior to the official Congress Opening Ceremony two special programs were held.

Fifty Years of Research and Mentoring: Symposium in Honor of the Life and Career of Fumio Matsumura

This symposium, sponsored by Mrs. Teruko Matsumura & family, honored the life and career of Professor Fumio Matsumura, Distinguished Professor of Environmental Toxicology and Ento-mology, UC Davis, who passed away unexpectedly in December 2012. For some 50 years he was at the cutting edge of both pesticide and environ-mental toxicology, and his pioneer-ing research has helped define both

fields. The symposium consisted of two main topics: Mode of Action of Insecticides and Environmental Pollutants and Genomics, Molecular Biology and Bioinformatics of Insec-ticide Resistance. Twenty-one internationally recognized speakers gave presentations that will be published in a Special Issue of Pesticide Biochemistry & Physiology, a journal that Matsumura edited from 1991-2010.

Developing Global Leaders for Research, Regulation, and Stewardship of Crop Protection Chemistry in the 21st Century

The purpose of this workshop was to bring together global crop protection chemistry leadership from academia, industry, government and non-governmental organizations to examine current state of affairs in this field. It began with presentations by John Unsworth, Chair, IUPAC Advisory Committee on Crop Protection Chemistry, and other international experts to review crop protection chemistry megatrends and leadership training needs. After a series of breakout discussion sessions, participants re-gathered to develop a set of recommendations for ensuring that tomorrow›s crop protection chemistry lead-ers have a well-rounded, science-based and globally-informed approach. The final workshop report will be published to help guide cooperative leadership development efforts among crop protection chemistry stakeholders.

PublicationsCongress organizers have encouraged development of special journal issues, books and other publications. Plans are under-way for publishing plenary lectures as well as symposia topics in outlets that will have the greatest impact for scientists in the particular areas of research. Information on post-Congress publications will be available via the www.iupac2014.org website, which will be updated with various post-meeting information and photos.
