Metabolic Resistance to Herbicides: What we Know and Why it Matters
Todd Gaines, Colorado State University
April 10, 2019 from 12 to 1 PM Eastern Daylight Time
Moderated by Steve Duke
Weeds can evolve resistance to herbicides through enzymatic mechanisms to metabolize and detoxify herbicide molecules. Recent advances have revealed specific genes controlling metabolic resistance such as cytochrome P450s, glutathione-S-transferase, and others, primarily in grasses but also in broadleaf weeds. Metabolic resistance can result in unpredictable cross-resistance patterns that further complicate management recommendations. This webinar will summarize major recent findings and outline current knowledge gaps for metabolic herbicide resistance.
RECENT WEBINARS – View Recordings
Incorporating the Benefits of Vegetative Filter Strips into Risk Assessment and Risk Management of Pesticides
March 13, 2019 12 to 1 PM Eastern Standard Time
Moderated by Laura McConnell
This webinar is a collection of selected plenary presentations from the recent Workshop on Innovation and Regulation in Agriculture held in Raleigh, North Carolina. Vegetative filter strips (VFS) are widely used by producers to mitigate runoff and erosion from production areas. VFS effectiveness for mitigating nutrient runoff and soil erosion is well-established. A growing body of literature has shown that VFS are also effective at mitigating pesticide runoff. Currently the contribution of VFS are not considered in the standard pesticide exposure assessment scenarios utilized by US EPA. This webinar will provide a variety of viewpoints and scientific evidence on VFS from regulatory, academia, government and industry and will describe recent outcomes from the workshop.
INNOVATIVE APPROACHES TO EXPLOIT HOST PLANT METABOLITES IN MALARIA CONTROL
Baldwyn Torto, Department of Zoology and Entomology, University of Pretoria, South Africa
February 13, 2018 12 to 1 PM Easter Standard Time
Moderated by John Beck
Seventeen percent of the global infectious diseases are vector-borne which results in more than 700,000 deaths annually. Malaria ranks highest among these diseases, causing over 400,000 deaths yearly, mainly in children under 5 years of age. However, over 90 % of the global malaria burden disproportionately affects sub-Saharan Africa. A substantial gain in malaria control and consequent reduction in malaria deaths has been achieved between 2000 and 2015 attributed to a combination of interventions including long-lasting insecticide-treated nets (LLINs), indoor residual spraying (IRS), prompt diagnosis and treatment with artemisinin-based combination therapies (ACTS). Spurred by the progress, the WHO Global Technical Strategy for Malaria 2016-2030 proposes to reduce malaria deaths by at least 40% by 2020 and malaria incidence and mortality rates by at least 90% by 2030 and eradication by 2040. Surprisingly, malaria reduction has stalled or plateaued, with the levels of malaria associated mortality and morbidity remaining the same in 2015, 2016 and 2017.
Clearly, complementary new strategies are urgently required if the WHO target can be achieved considering challenges to existing interventions such as the emergence of vector insecticide and behavioral resistance to indoor control and parasite resistance to ACTs. We argue that to develop the next generation of vector control and chemotherapeutic tools, especially based on natural products, a better understanding of mosquito ecology is needed. This presentation will highlight progress in our study of mosquito-plant interactions towards development of promising leads for malaria control.
HESI’s Risk Assessment in the 21st Century (RISK21) Framework: Overview and Applications
Michelle R. Embry, Ph.D, Associate Director Environmental Science, Health and Environmental Science Institute
December 12, 2018 12 to 1 PM Easter Standard Time
Moderated by Paul Reibach
The HESI Risk Assessment in the 21st Century (RISK21 project developed an integrated risk assessment framework to enhance efficiency and risk management. This framework is an problem formulation-based, exposure driven, tiered data acquisition approach that allows an informed decision on safety to be made when sufficient evidence is available and is risk-based at every step. This approach maximizes the ability to inform decisions and optimize resource usage, and the program also developed a web-based tool that allows users to easily communicate risk-based decisions, whether for a screening and prioritization purpose or a definitive risk assessment. This tool is freely available at www.risk21.org. This webinar will provide an overview of the RISK21 framework and discuss several case study applications.
