- Weed Science Societies Provide Comments to Improve EPA’s Herbicide Strategy for Endangered Species Mitigations.
The Weed Science Societies suggest nine additional ways to mitigate the impact of herbicides on listed species due to spray drift, which includes decreased buffers for ultra-coarse droplets, additional types of vegetation to intercept spray droplets and grower education. We also suggest six additional ways to mitigate herbicide runoff and erosion, which also includes grower education, more specific terminology for agricultural vs specialty crops as well as assigning more compensatory mitigation points for fields with subsurface drainage or cover crop practices. Most importantly, the Weed Science Societies want to stress that grower education will be the most effective way to implement EPA’s Herbicide Strategy. We recommend a minimum of a 3-5 year phase-in period for the herbicide strategy ESA mitigation practices, which corresponds to the 3-5 year interval that pesticide applicators must be recertified.
The Weed Science Societies also present the results of a survey of weed scientists from across the country that looked at the 13 crop scenarios for pesticide runoff and erosion mitigation points that the EPA provided, plus 2 additional crop scenarios. Alarmingly, only 2 of the 15 crop production scenarios, or 13%, could obtain the nine runoff/erosion mitigation points considered necessary to maintain existing weed control practices. We provide additional information on conservation specialists and programs in different states as well as a rationale for why EPA should create a database of the mitigation points needed by crop, pesticide use limitation area (PULA), and herbicide. We provide suggestions to enhance “Bulletins Live Two!” as well as a list of topics in dire need of research funding so we can best help protect T&E species and their critical habitat. Finally, we have provided a list of suggested education and training activities to successfully launch the ESA mitigation practices for pesticides.
WSSA Comments on EPA’s Vulnerable Species Pilot Project for Endangered Species.
On August 6, 2023, the WSSA submitted comments (link here) on the U.S. EPA’s proposed Vulnerable Listed Species Pilot Project: Proposed Mitigations, Implementation Plan, and Possible Expansion. The WSSA is requesting the agency consider the many benefits of developing WSSA-EPA working groups to cooperatively and more effectively address issues facing herbicides, including the endangered species act. The WSSA is also committed to working with the agency to 1) generate dependable, accurate, and usable science-based data, thereby improving the regulatory process, and 2) provide a direct connection to research and extension experts working with herbicides across environments in real-world situations.
- Stakeholders Seek Funding for U.S. DOT Invasive Plant Elimination Program
The six national and regional weed science societies are signatories on the USDOT Invasive Plant Elimination Program Support Letter to Congress, which requests $10 million to start a pilot program for the Invasive Plant Elimination program authorized the 2021 Infrastructure bill.
- Weed Science Society Presidents Visit Washington DC.
During the week of April 17, the presidents from the four regional weed science societies and WSSA traveled to Washington DC to advocate on behalf of weed science policy initiatives and help WSSA achieve its mission of promoting research, education, and awareness of weeds in managed and natural ecosystems. Our primary mission during the week was meeting with the president’s elected members of Congress and their staff from their home states. We discussed an array of weed science related topics.
- The National and Regional Weed Science Societies Comment on EPA’s Endangered Species Act Workplan
On November 16, the EPA released an Updated ESA Workplan that provides more details about how EPA plans to impose various mitigation measures that will be required on pesticide labels to meet its ESA obligations when registering a pesticide. There are concerns about some of the mitigation options such as “buffers to reduce pesticide drift and water runoff” or “do not use when rain is expected in the next 48 hours” — which raises other issues such as what or how compliance might be proven or enforced.
The ESA Workplan Update also describes initiatives that, according to EPA, will help it and other federal agencies improve approaches to mitigation under the ESA and improve the interagency consultation process outlined in the ESA Workplan. These initiatives include EPA’s work to identify ESA mitigation measures for pilot species, incorporate early ESA mitigation measures for groups of pesticides (e.g., broadleaf herbicides), and develop region-specific ESA mitigations.
- Weed Science Societies Urge Congress to Pass the 5th Reauthorization of the Pesticide Registration Improvement Act (PRIA 5). PRIA 5 Support Letter PRIA established a new section of FIFRA in 2004 that put in place pesticide registration service fees paid by registrants in exchange for specific time periods for EPA to make a regulatory decision on pesticide registrations and tolerance actions. The goal of PRIA was to create a more predictable and effective evaluation system that promoted shorter decision review periods for reduced-risk applications. PRIA’s enactment spurred process improvements and provided the pesticide industry, user groups, and interested stakeholders with more clarity and certainty on the registration process

Glyphosate Letter to US Solicitor General
Dear President Biden:
We write to express our grave concern with a recent change in long-standing policy regarding the regulation and labeling of pesticide products relied upon by farmers and other users. At a crucial time when American farmers are striving to feed a world threatened by food shortages and insecurity, the likes of which we have not seen in decades, this reversal of policy greatly risks undermining the ability of U.S. agricultural producers to help meet global food needs. This policy also poses significant risks to farmers and other herbicide users for whom these tools are essential to combat climate change and other environmental challenges. With so much at stake, it is vital that we have durable, predictable, science-based policy on this matter that does not fluctuate between administrations. We strongly urge you to withdraw the brief establishing this new policy, fully considering the implications it holds for global food security, environmental sustainability, and the future of science-based regulation.
- WSSA supports the Bureau of Land Management’s (BLM) notice of intent to prepare a Programmatic Environmental Impact Statement (PEIS) for approval and use of the following herbicide active ingredients in vegetation treatments on public lands.
- National and Regional Weed Science Societies request an appropriation of $700 million for the USDA AFRI competitive grants program in FY 2023.
- WSSA requests a 10% increase in funding for USDA-ARS in FY 2023 to $1.9 billion.
- WSSA SUPPORTS AG RESEARCH FUNDING IN RECONCILIATION PROPOSAL
- The WSSA sent a letter to Congressional leadership in support of the $7.75 billion for agricultural research in the Budget Reconciliation proposal. One letter highlighted the $500 million in additional funding proposed for the Agriculture and Food Research Initiative (AFRI). A second letter, which was coordinated by the National Coalition for Food and Agriculture Research (NCFAR), also requested support for the $7.75 billion designated for agricultural research. That letter was endorsed by over 120 stakeholder groups including the six national and regional weed science societies.
- WEED SCIENCE SOCIETIES SUPPORT INVASIVE SPECIES FIXES
The six national and regional weed science societies supported two letters that would improve invasive species management. The first letter (CEQ letter) requests that the Council on Environmental Quality (CEQ) approve the Department of the Interior’s request for a number of categorical exclusions under the National Environmental Policy Act (NEPA) for invasive species control. Without the ability to use categorical exclusions to promptly control invasive annual grasses after a fire on federal lands, those invasive grasses have spread rapidly while federal land managers have to go through the NEPA process, which has taken years in many cases, before those invasive grasses can be managed. The second letter (S.626) supports legislation in the Senate that would fix a flaw in the Lacey Act, that came about through a federal court case, where the court interpreted that the US Fish and Wildlife Service (FWS) could not regulate interstate commerce in injurious species, notwithstanding decades of generally accepted practice during which FWS had exercised that authority.
- WEED SCIENCE SOCIETIES REQUEST OVER $350 MILLION INCREASE FOR FY 2022 INVASIVE SPECIES MANAGEMENT
The six national and regional weed science societies joined over 35 other organizations in a letter to House and Senate Appropriations Committee leaders with recommendations for FY 2022 invasive species management funding levels. The recommendations total over $350 million above FY 2021 spending levels and cover all taxa of invasive species at USDA, Interior, EPA, Army Corps, NOAA, and NASA. Invasive species management efforts are extremely underfunded, especially in the Department of the Interior. For example, the Bureau of Land Management (BLM) only spends approximately $15 million per year for invasive species management activities on its 245 million acres that it manages. That is only 6 cents per acre for invasive species prevention, research, early detection/rapid response (EDRR), control, restoration and education.
- WSSA SUBMITS “FARM OF THE FUTURE” COMMENTS
The WSSA submitted both written and oral comments for a proposal about what technologies should be available to a “farm of the future”. The proposal, which was included in the FY 2022 appropriations bill, states that USDA-NIFA shall award $4 million for a competitive grant to an institution in the land-grant university system to establish a Farm of the Future testbed and demonstration site.
- SUPPORT FOR $11.5 BILLION IN AG RESEARCH INFRASTRUCTURE
The Weed Science Societies joined over 350 other national, regional, and state ag organizations and companies in a letter to House and Senate Agriculture Committee leadership to request their support for $11.5 billion in ag research infrastructure investments over five years. This investment in our 1862, 1890, and 1994 land grant and non-land grant schools of agriculture is necessary in order to ensure the U.S. remains a global leader in food and agricultural innovation. A recent Gordian/APLU study assessed the state of facilities at U.S. colleges and schools of agriculture this year and reported that 69% of these buildings are at the end of their useful life.
- LEGISLATION TO BOOST USDA RESEARCH FUNDING REINTRODUCED
Senators Dick Durbin (D-IL) and Jerry Moran (R-KS), reintroduced legislation, S. 1371, that would require a five percent annual funding increase each year for the next 10 years for research activities at USDA’s ARS, NIFA, NASS, and ERS. The U.S. share of total agriculture research investments among high-income countries as a group has declined from 35 percent in 1960 to less than 25 percent by 2013. By comparison, in the past 30 years, Chinese investments in agriculture research has risen eight-fold. The six National and Regional Weed Science Societies have joined over 100 other organizations in supporting the bill.
- WSSA COMMENTS ON EPA DRAFT BIOLOGICAL EVALUATIONS FOR GLYPHOSATE
EPA’s glyphosate biological evaluations (BEs) lack a workable and consistent approach to endangered species assessments. An assessment process which essentially equates any exposure to a pesticide as a possible concern to any species does little to advance appropriate options which could be tailored to improve species protection. The implications of unrealistic analyses will result in unjustified restrictions on the use of glyphosate products which remain critical weed management tools across the U.S.
- NATIONAL INVASIVE SPECIES AWARENESS WEEK (NISAW): SHOW ME THE MONEY: MOVING FROM AUTHORIZATION TO APPROPRIATIONS
Presented on Feb. 26, 2021. The U.S. federal agencies responsible for invasive species management in aquatic and terrestrial ecosystems, in general, have sufficient legislative authority from Congress to manage invasive species. However, federal invasive species programs remain extremely underfunded. In FY 2020, the Department of the Interior estimated it spent $143 million to manage invasive species for 400+ million acres of public lands. That’s roughly 35 cents per acre for all invasive species research, prevention, EDRR, management and restoration. As invasive species stakeholders, we need to seek full appropriations as authorized for these programs. This presentation reviews the leaders and members of four of the Appropriations Subcommittees in the 117th U.S. Congress that have jurisdictions for funding invasive species management programs.
- WSSA COMMENTS ON EPA DRAFT BIOLOGICAL EVALUATIONS FOR THE TRIAZINES
EPA’s triazine biological evaluations (BEs) lack a workable and consistent approach to endangered species assessments. An assessment process which essentially equates any exposure to a pesticide as a possible concern to any species does little to advance appropriate options which could be tailored to improve species protection. The implications of unrealistic analyses will result in unjustified restrictions on the use of triazine products which remain critical weed management tools across the U.S.
- WSSA COMMENTS ON PARAQUAT PROPOSED INTERIM DECISION
Given the value of paraquat as a unique weed management tool and the updated human health mitigation measures, WSSA is opposed to the following two application restrictions proposed by EPA: 1) prohibition of all aerial applications of paraquat except for cotton desiccation; and 2) prohibition of all paraquat applications using mechanically pressurized handguns and backpack sprayers. Those application restrictions would eliminate many unique weed management options and put undue pressure on other broad-spectrum burndown treatments.
- SOCIETIES URGE PASSAGE of FY 2021 APPROPRIATIONS and COVID RELIEF BILLS
In early December, WSSA and APMS joined more than 170 other organizations and institutions across all disciplines and areas of science and research in a letter to congressional leadership, urging swift action to finalize the annual funding levels for science agencies and programs and provide emergency research relief funding to mitigate the impact of the COVID-19 pandemic.
- WEED SCIENCE SOCIETIES COMMENT ON INTERIOR’S DRAFT INVASIVE SPECIES STRATEGIC PLAN
The National and Regional Weed Science Societies applaud the Department of the Interior’s efforts to develop a concise, yet comprehensive Invasive Species Strategic Plan. Invasive weeds are a significant problem with their potential roles in displacing native species, altering structure and function of ecosystems, disrupting natural and agricultural landscapes, and causing economic damage. Invasive weeds in terrestrial and aquatic ecosystems are estimated to cost nearly $30 billion per year.
- WEED SCIENCE SOCIETIES OPPOSE NEGUSE/UDALL LEGISLATION
The National and Regional Weed Science Societies, joined by more than 300 agriculture and conservation organizations, sent a letter to all members of the U.S. Senate and House of Representatives affirming their support for pesticide regulations under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). The letter is in response to recently introduced legislation (H.R. 7940, S. 4406) by Rep. Neguse and Sen. Udall that would undermine the science-based standards contained within our nation’s pesticide laws.
- WEED SCIENCE SOCIETIES SUPPORT $380 MILLION SUPPLEMENTAL APPROPRIATIONS REQUEST FOR AG RESEARCH, EDUCATION, AND EXTENSION
The National and Regional Weed Science Societies joined over 270 other national, regional and state organizations to urge Congress to provide $380 million to our agricultural research, education, and extension system as it considers the next supplemental appropriations package in response to COVID-19. This request reflects a commitment to agriculture, families, businesses, and communities. It includes $300 million of job-saving support for USDA-NIFA capacity and competitive research and is consistent with the research community’s broader recommendations across the science agencies. Dramatic disruptions to our research talent pipeline, including the facilities and equipment that support it, will require additional support. The request also supports an $80 million request for the Cooperative Extension System to meet the direct needs of the public related to spread of, and recovery from, COVID-19. The synergy between research and extension is essential.
- WEED SCIENCE SOCIETIES COMMENT ON THE REVISION OF APPLICATION EXCLUSION ZONE REQUIREMENTS
The Weed Science Society of America (WSSA), along with the Aquatic Plant Management Society, the North Central Weed Science Society, Northeastern Weed Science Society, Southern Weed Science Society and the Western Society of Weed Science welcome the opportunity to comment on the Revision of the Application Exclusion Zone (AEZ) Requirements. We applaud the Environmental Protection Agency (EPA or the Agency) for its efforts and time on the current standards and for allowing public comments to improve and simplify the AEZ for pesticide applicators. In this letter, the National and Regional Weed Science Societies communicate our support for the proposed changes to the AEZ Requirements.
- WSSA COMMENTS ON PARAQUAT
The WSSA appreciates the opportunity to provide comment on the value and uniqueness of paraquat for weed management. We strongly support further education and awareness activities both on the label and through training. Read the full comment on ‘Registration review; Availability: Paraquat Dichloride Draft Human Health and Ecological Risk Assessments’.
- WEED SCIENCE SOCIETIES COMMENT ON EPA’S INTERIM PROCESS FOR EVALUATING POTENTIAL SYNERGISTIC EFFECTS OF PESTICIDES DURING THE REGISTRATION PROCESS
To date, EPA has used an interim process to evaluate 24 new active ingredient registrations. None of these reviews have ultimately impacted an existing EPA ecological risk assessment. The results from the analysis of the first 24 active ingredients reflects that there is a low probability that claims asserting greater than additive (GTA) effects will impact ecological risk assessments for pesticide active ingredients. Therefore, the National and Regional Weed Science Societies support EPA’s plans to evaluate the results of the interim process, and once a sufficient number of reviews are completed, to decide whether continuing the process has utility in evaluating ecological risk associated with product use. If the outcome of EPA’s future evaluation demonstrates that the interim process does not have utility in evaluating ecological risk associated with product use, our societies agree that EPA and registrants should not exhaust additional time and resources in this endeavor and suspend evaluations.
- AMERICA GROWS ACT WOULD BOOST AG RESEARCH FUNDING
The six National and Regional Weed Science Societies joined over 80 other organizations in supporting legislation introduced by Senator Dick Durbin (IL) that would authorize a 5% inflation-adjusted annual increase for the next 5 years for agricultural research at USDA-ARS, NIFA, ERS, and NASS. The America Grows Act (S. 2458) is modeled after the 21st Century Cures Act passed in 2016, which spurred additional funding for NIH.
- WSSA’S POSITION ON GLYPHOSATE
In 2015, glyphosate was classified as a “probable carcinogen” by the International Agency for Research on Cancer (IARC). IARC has applied the same classification to red meat, hot beverages, and emissions from high-temperature frying, as well as to more than 70 other chemicals. This designation has caused widespread public concern about the safety of glyphosate while being the recent focus of multiple lawsuits. WSSA has developed this document to inform the membership and general public of its position on this topic.
- WEED SCIENCE SOCIETIES COMMENT on EPA’s PROPOSED INTERIM REVIEW DECISION for GLYPHOSATE
The National and Regional Weed Science Societies compliment EPA on the many positive aspects of their proposal to mitigate potential risks with glyphosate use while noting its importance in the management of invasive and noxious weeds in agricultural and non-agricultural settings. Scientific literature has clearly shown that the benefits of glyphosate outweigh any potential ecological risks. We agree that improvements to labels that are consistent across all glyphosate products will help to further mitigate these risks.

- SUPPORT IR-4 AT $19 MILLION IN FY 2019
There is currently a push to get IR-4 funded at $19 million in FY 2019. Annual funding for IR-4 has been stagnating at around $11.9 million for nearly a decade. On April 26, Sen. Menendez (D-NJ) sent a “Dear Colleague” letter to Senate Ag Appropriations Committee Chair John Hoeven (R-ND) and Ranking Member Jeff Merkley (D-OR) requesting an appropriation of $19 million for the IR-4 Project for FY 2019. The letter was co-signed by 13 Senators and supported through the efforts of the IR-4 Commodity Liaison Committee, the Minor Crop Farmers Alliance, and endorsed by nearly 60 organizations including the six National and Regional Weed Science Societies.

- CAST PAPER ON CROP PROTECTION CONTRIBUTIONS TOWARD AGRICULTURAL PRODUCTIVITY
The authors of this CAST Issue Paper examine the current plant protection revolution that is driven by the biological realities of pesticide resistance, various market forces, and real or perceived side effects of pesticides. They point out that “crop protection chemicals have been miraculous, but their automatic use is no longer efficacious or justifiable.” Led by Task Force Chair Susan T. Ratcliffe, the authors of this paper consider new technologies such as drones, smart sprayers, and specially designed cultivators–and they examine current biotech advancements such as CRISPR-Cas9 and other techniques that may fit well into integrated systems. They emphasize the need for research, communication, and collaboration as scientists “develop integrated strategies for managing pests while preserving ecosystem services and farm productivity.” The paper can be downloaded from here.
- WSSA COMMENTS ON TRIAZINE DRAFT ECOLOGICAL ASSESSMENT
Oct. 5, 2016. A number of concerns have been raised by various stakeholders relative to EPA’s draft ecological risk assessment for the triazines. These concerns include: errors in endpoint data and the water monitoring database; use of models that are not validated with field data; estimates of inflated hypothetical risks (e.g. atrazine applications resulting in 36% bird mortality) that have not been observed in over 55 years of atrazine use; use of data or findings not conducted in accordance with EPA’s scientific guidelines required under FIFRA; and ignoring the advice and findings of previous Science Advisory Panels on atrazine. The WSSA stresses the importance of addressing these concerns in order to maintain stakeholder confidence in the Agency’s science-based regulatory framework. However, our main concern, based on the current ecological draft risk assessment, is that atrazine and simazine would be restricted to less than 0.25 lbs a.i./A and 0.5 lbs a.i./A, respectively. At these low rates, atrazine and simazine would not provide efficacious weed control. In addition, using sub-lethal rates of atrazine or simazine is not an effective option for resistance management as it has been shown that this practice is likely to result in weeds with multiple-site or polygenic resistance which would make it more difficult to control these weeds. Comments are here.
- WSSA COMMENTS ON FIFRA SCIENCE ADVISORY PANEL (SAP) REVIEW OF GLYPHOSATE CARCINOGENICITY
Oct. 4, 2016. WSSA fully supports EPA’s Cancer Assessment Review Committee’s (CARC) report on glyphosate (Docket ID: EPA-HQ-OPP-2016-0385-0014) and appreciates the scientific rigor and thoroughness of the CARC’s review of all available epidemiology and carcinogenicity studies. WSSA agrees with the CARC’s assessment that the few studies that the International Agency for Research on Cancer (IARC) selectively chose for its glyphosate review suffered from small sample sizes of cancer cases related to glyphosate exposure and had risk/odds ratios with large data variance beyond acceptable limits. Furthermore, WSSA feels that the IARC review process for glyphosate was flawed and represents a case of gross scientific negligence. There is no question that IARC arrived at their conclusion due to their inclusion of the positive findings from a selection of studies with known limitations, a lack of reproducible positive findings, and the omission of the negative findings from credible and reliable research. Finally, WSSA commented on the ongoing importance of glyphosate as a weed management tool and submitted information we developed surrounding some common misconceptions about glyphosate and herbicide resistance management. Comments are here.
- WEED SCIENCE SOCIETIES COMMENT ON EPA’S DRAFT GUIDANCE ON HERBICIDE RESISTANCE MANAGEMENT
Sept. 1, 2016. This summer EPA issued a Pesticide Registration Notice (PRN) that proposes an approach to address herbicide-resistant weeds by providing guidance on labeling, education, training, and stewardship for herbicides undergoing registration review or registration. The National and Regional Weed Science Societies recognize the critical need to protect all available weed management tools and are on record supporting proactive measures by EPA to combat the further evolution and spread of herbicide-resistant weeds. EPA’s proposal represents a significant change in how resistance is monitored, mitigated and communicated to weed management stakeholders. We consider this proposal a first iteration that will need adaptation and evolution as our experience with it grows and we hope the Agency has those same expectations. Comments are here.
- EPA MANUAL AVAILABLE ON HOW TO COMPLY WITH THE REVISED WORKER PROTECTION STANDARDS
The EPA in conjunction with the Pesticide Educational Resources Collaborative (PERC) has made available a guide to help users of agricultural pesticides comply with the requirements of the 2015 revised federal Worker Protection Standard (WPS). You should read this manual if you employ agricultural workers or handlers, are involved in the production of agricultural plants as an owner/manager of an agricultural establishment or a commercial (for-hire) pesticide handling establishment, or work as a crop advisor. The “How to Comply” manual includes:
• Details to help you determine if the WPS requirements apply to you
• Information on how to comply with the WPS requirements, including exceptions, restrictions, exemptions, options, and examples
• “Quick Reference Guide”- a list of the basic requirements (excluding exemptions, exceptions, etc.) new or revised definitions that may affect your WPS responsibilities, and
• Explanations to help you better understand the WPS requirements and how they may apply to you.
The revised EPA Pesticide Worker Protection Standard “How to Comply” Manual is available here.
- 2016-2018 NISC MANAGEMENT PLAN
The National Invasive Species Council (NISC) announced the release of their 2016-2018 Management Plan. The plan sets forth high priority, interdepartmental actions for the Federal government and its partners to take to prevent, eradicate, and control invasive species, as well as restore ecosystems and other assets adversely impacted by invasive species. The thirteen Federal Departments and Agencies whose senior officials comprise NISC will:• Provide Federal leadership on invasive species issues by establishing the structures, policy, and planning priorities necessary to enable Federal agencies to effectively prevent, eradicate, and/or control invasive species, as well as restore impacted ecosystems and other assets;
• Limit the spread and impact of invasive species through high-level policy and planning by strengthening coordination between the United States and other governments, across the Federal government, and between the Federal government and non-governmental stakeholders;
• Raise awareness of the invasive species issue and mobilize the policies, programs, and financial resources necessary to minimize the spread and impact of invasive species;
• Remove institutional and policy barriers to the Federal actions needed to prevent, eradicate, and control invasive species, as well as restore ecosystems and other assets;
• Conduct assessments of Federal capacities to meet the duties set forth in Executive Order 13112, as well as other high-level policy priorities, and build Federal capacities, as needed;
• Foster the scientific, technical, and programmatic innovation necessary to enable Federal agencies and their partners to prevent and mitigate the impacts of invasive species in a timely and cost-effective manner with negligible impacts to human and environmental health.
The 2016-2018 NISC Management Plan is available here.
- FHWA ROADSIDE REVEGETATION HANDBOOK WITH EMPHASIS ON POLLINATORS
In its first major update since 2007, the Federal Highways Administration (FHWA) has expanded their roadside revegetation manual to include a major emphasis on pollinators. The handbook is now titled “Roadside Revegetation: An Integrated Approach to Establishing Native Plants and Pollinator Habitat”. With at least 17 million acres of roadsides in the U.S., roadside vegetation can serve as much needed habitat for pollinators, offering food, breeding, or nesting opportunities and connectivity that can aid pollinator dispersal. Roadside vegetation management influences how pollinators use roadsides, and even influences the number of pollinators killed by vehicles. For example, butterfly vehicle mortality rates increase with more frequent mowing and decrease with high plant diversity in roadside vegetation.
The publication is written specifically for the “designer,” those individuals or members of a road design team who will be directly involved in planning, implementing, monitoring, or maintaining a revegetation project.

- REPORT – EVERY $1 INVESTED IN AGRICULTURAL RESEARCH RETURNS $10 WORTH OF BENEFITS TO THE ECONOMY
Over the last several decades, the U.S. agricultural sector has sustained impressive productivity growth. The Nation’s agricultural research system, including Federal-State public research as well as private-sector research, has been a key driver of this growth. Economic analysis finds strong and consistent evidence that investment in agricultural research has yielded high returns per dollar spent.
- WSSA REPORT – DETERMINATION OF THE POTENTIAL IMPACT FROM THE RELEASE OF GLYPHOSATE- AND GLUFOSINATE-RESISTANT AGROSTIS STOLONIFERA L. IN VARIOUS CROPS AND NON-CROP ECOSYSTEMS
The Weed Science Society of America (WSSA) was asked by the United States Department of Agriculture-Animal Plant Health Inspection Service (USDA-APHIS) to perform an analysis of the weed management implications associated with the potential deregulation and commercialization of glyphosate and glufosinate-resistant creeping bentgrass (Agrostis stolonifera L.) varieties. This analysis is needed to determine the current and potential significance of creeping bentgrass, and other species with which it can hybridize (several other Agrostis spp. and Polypogon spp.), as weeds in managed and non-managed ecosystems in the United States. The analysis deliberately focused exclusively on the weed management implications of the potential release of these creeping bentgrass varieties and did not attempt to assess other associated environmental and economic considerations. The Weed Science Society of America does not endorse or oppose the proposed deregulation of glyphosate- or glufosinate-creeping bentgrass. The information contained in this report does not represent a position for or against the technology and should not be interpreted as such. This work was done at the request of USDA/APHIS to provide science-based information for their use as a regulatory agency.
