On September 9, 2019, the U.S. Environmental Protection Agency (EPA) Office of Pesticide Programs (OPP) published a notice in the Federal Register announcing the availability of, and an opportunity for comment on, a document describing an “interim process” that OPP’s Environmental Fate and Ecological Effects Division is currently using to evaluate potential synergistic effects of mixtures of pesticide active ingredients on non-target organisms. As part of a lawsuit challenging the 2012 decision by EPA to register Enlist Duo Herbicide (a combination of 2,4-D and glyphosate), OPP scientists learned that patent applications for some registered pesticide products included claims that particular combinations of active ingredients provide “synergistic” control of target species. Although EPA was not at that time considering potential synergies in assessing the risk for ecological effects on non-target organisms, based on the patent application claims regarding synergy for Enlist Duo, EPA decided to request that the reviewing court vacate its registration decision and remand the application for Enlist Duo for further study of these effects and any measures that might be needed to mitigate the risk to non-target organisms. This decision sparked much controversy, and many in industry were concerned that patent application claims were not being correctly interpreted by EPA for the category of pesticide products at issue.
The new document released by EPA for review and comments is entitled: “Process for Receiving and Evaluating Data Supporting Assertions of Greater Than Additive (GTA) Effects in Mixtures of Pesticide Active Ingredients and Associated Guidance for Registrants.” EPA states that it “has generally been applying this interim process since 2016.” The process described in the document has five steps: (1) registration applicants must search for any granted patents that include synergy (GTA) claims for combinations of pesticides; (2) applicants must review the patent claims and supporting data for relevance to ecological risk assessment; (3) applicants must report to EPA all effects testing data from the relevant patents; (4) applicants must do a statistical analysis (using a method prescribed by EPA) to determine whether any observations of GTA effects are statistically significant; and (5) EPA will review all submitted information to decide whether it should be utilized in ecological risk assessment.
In the Federal Register notice, OPP lists five specific areas pertaining to the interim risk assessment process described in the document on which it is requesting comment:
- Are there technical aspects of the interim process that warrant change? If so, what changes are recommended?
- What aspects of the process could be applied to the evaluation of open literature sources of GTA effects pesticide interactions?
- Should EPA consider standardizing a more detailed search and reporting approach, and how should EPA do that?
- Should EPA continue the evaluation process as described in this document? If so, what performance metrics (e.g., number of evaluations) should EPA consider before deciding the utility of this approach?
- What applicant burden is associated with the activities described in this memorandum, including compiling, analyzing, and submitting the information? Specifically, does an estimate of 80-240 hours of burden per applicant cover the respondent burden associated with the interim process?
When the National Research Council (NRC) evaluated the importance of toxicological interactions between pesticide active ingredients in 2013, the NRC concluded that such interactions are rare, but that EPA should nonetheless consider such interactions when the best available scientific evidence supports such an evaluation. In the current Federal Register notice, EPA makes it clear that it is uncertain concerning the utility for risk assessment of the information used by manufacturers to support synergistic effects claims in pesticide patents. According to EPA, 24 applicants for new registrations have submitted patent data to date, but only three of these submissions contained information that indicated a need for further testing and no submission ultimately led to any adjustment of the ecological risk assessment. At this juncture, EPA will continue collecting patent data that may be pertinent to GTA effects, but when it has sufficient experience upon to base a general policy it may either continue or improve this process or discontinue it after explaining why.
When EPA requested that the reviewing court vacate and remand the registration EPA had granted for Enlist Duo, the parties seeking judicial review located data in the patent applications that EPA had not previously seen or reviewed and that EPA believed could possibly be pertinent to potential adverse effects on non-target plants. EPA concluded that it should revisit the decision based on the additional data. Although EPA decided to request vacatur and remand, the applicant Dow AgroSciences had arguably followed all of the procedures then in place, because FIFRA Section 3(c)(5) allows EPA to waive data requirements pertaining to efficacy, and EPA typically registers pesticide product that are not intended to protect public health without any independent evaluation of efficacy data. Nevertheless, in general EPA may choose to evaluate pesticidal efficacy data; such circumstances in the past often involved cases where EPA was required to consider whether pesticide benefits are sufficient to outweigh identified risks. In the Enlist case, EPA determined that it should do so where potential synergy in pesticidal efficacy is pertinent to evaluating ecological effects on non-target species.
What EPA must decide now is how often efficacy data that has been deemed adequate by the Patent and Trademark Office to support a patent for a new pesticide mixture will have any material significance in the context of ecological risk assessment. Before EPA makes a determination whether or not patent data has sufficient pertinence to continue requiring routine collection and evaluation of such data, EPA has decided it is prudent to afford all stakeholders an opportunity to comment on whether EPA has been asking the right questions.
All comments on the draft document must be submitted no later than October 24, 2019.

On May 28, 2019, the California Department of Pesticide Regulation (DPR) posted a new presentation identifying the top ten agricultural pesticide use violations of 2018. Its announcement states that “DPR suggests reviewing these common violations of pesticide laws and regulations to help ensure … compliance.” The presentation, “Top 10 Agricultural Pesticide Use Violations of 2018,” is available here. The violations are listed from the least common (number 10) to the most common (number 1):
10. Handler Training, regulated under Title 3 of the California Code of Regulations (C.C.R.) § 6724. Examples of handler training violations listed in the presentation are: not updating employee training before a new pesticide is handled; and not providing employees handler training before they work on or repair equipment previously used to apply pesticides.
9. Application-Specific Information (ASI) for Fieldworkers, regulated under 3 C.C.R. § 6761.1. Examples of violations listed in the presentation are: not including a specific description of the location of the ASI on the Pesticide Safety Information Series (PSIS) A-9 leaflet so that workers have unimpeded access; and not displaying the ASI before fieldworkers work in a treated field.
8. Hazard Communication for Fieldworkers, regulated under 3 C.C.R. § 6761. Examples of these types of violations listed in the presentation are: not retaining Safety Data Sheets (SDS) for the pesticides listed in the pesticide use records within the past two years; and not informing employees or the Farm Labor Contractor (FLC) of the location of the pesticide use records before the employees enter a treated field.
7. Handler Decontamination Facilities, regulated under 3 C.C.R. § 6734. Examples of these types of violations listed in the presentation are: not having an emergency eye flush station able to rinse the eye gently for 15 minutes at the mix and load site, when protective eyewear is required by the pesticide labeling; and handlers using hand sanitizer for decontamination instead of soap and water.
6. Availability of Labeling, regulated under 3 C.C.R. § 6602. Examples of labeling availability violations listed in the presentation are: not having relevant Special Local Needs (SLN) labeling at the site when mixing, loading, or applying; and not having the labeling booklets on-site when mixing, loading, or applying.
5. Service Container Labeling, regulated under 3 C.C.R. § 6678. Examples of service container labeling violations listed in the presentation are: not including the signal word on a service container label; and not including the address of the company or person responsible for the container on the label.
4. Annual Registration with County Agricultural Commissioner by Anyone Who Intends to Advertise, Solicit, or Operate as a Pest Control Business in California, regulated under California Food and Agriculture Code (FAC) § 11732. An example of a violation is performing pest control activities in a county before registering with the County Agricultural Commissioner (CAC).
3. Emergency Medical Care Requirements, regulated under 3 C.C.R. § 6726. Examples of violations listed in the presentation are: not taking employees suspected of a pesticide illness to the doctor immediately; and failure to post the handler emergency medical care information.
2. Personal Protective Equipment (PPE) Requirements, regulated under 3 C.C.R. § 6738. Examples of violations listed in the presentation are: storing PPE in the same place pesticides are stored; and an employer not providing the proper PPE required by the labeling.
1. Labeling and Permit Conditions Compliance, regulated under FAC § 12973. Examples of violations listed in the presentation are: not following the pesticide storage requirements listed on the labeling; and applying a pesticide to a site or crop not listed on the labeling.
Additionally, DPR has created an informative presentation about the 2019 license renewal process to help spread awareness to those renewing this year (last names and business names starting with M-Z). DPR states that it encourages continuing education (CE) sponsors, CAC staff, and others to use the presentation to inform license and certificate holders renewing this year about DPR’s renewal process, CE requirements, important dates, and the benefits of renewing early. The 2019 Renewal Process presentation is available here.

On April 19, 2019, the U.S. Environmental Protection Agency’s (EPA) Office of Pesticide Programs (OPP) announced that it will hold a public meeting of the Pesticide Program Dialogue Committee (PPDC) on May 8, 2019, from 9 a.m. to 5 p.m. and May 9, 2019, from 9 a.m. to 12:00 p.m. (EDT) in the first-floor conference center at One Potomac Yard South, 2777 South Crystal Drive in Arlington, Virginia. 84 Fed. Reg. 16486. The Federal Register notice states that the agenda is not yet available but that this meeting will provide advice and recommendations to EPA’s Administrator on issues associated with pesticide regulatory development and reform initiatives, evolving public policy and program implementation issues, and science issues associated with evaluating and reducing risks from use of pesticides. The draft agenda will be available on or before May 5, 2019, on the PPDC webpage. The meeting is open to the public and no advance registration is required.

On March 21, 2019, the U.S. Environmental Protection Agency (EPA) announced it was updating its Residual Time to 25% Bee Mortality (RT25) Data Table with information it has collected since the table was first published in 2014. EPA states that the “RT25 data help farmers and beekeepers know about how long a specific pesticide may remain toxic to bees and other insect pollinators following foliar application to crops,” and the new data “reflect the results of studies the agency has analyzed as part of [its] routine pesticide regulatory activities.” One example that EPA provides regarding how this new data will work is that farmers can now “choose pesticides that quickly lose their toxicity to bees,” and that applying the products in the evening “helps ensure that by morning the pests have been dealt with and blooming crops are safe for bees.”
EPA states that RT25 values are a function of a number of factors including application rate, physical-chemical properties, dissipation, crop, and pesticide formulation. The values provided were compiled from registrant-submitted data submitted to fulfill the data requirement for Honey Bee (Apis mellifera) Toxicity of Residues on Foliage study (OCSPP Guideline 850.3030). EPA states that the honey bee toxicity of residues on foliage study “is a laboratory test designed to determine the length of time over which field weathered foliar residues remain toxic to honey bees, or other species of terrestrial insects” and, depending on the chemical tested, “either the technical grade active ingredient or a specific formulation was tested using either the honey bee, alfalfa leaf cutting bee, or alkali bee.” The data table lists the test material, the species tested, and the plant species on which residues were aged.
EPA plans to update the table annually as it collects additional data going forward. More information on EPA’s actions intended to protect pollinators is available on EPA’s website.
In addition to providing the residual toxicity values, the table also illustrates the wide range of toxicity values among the various pesticides. RT25 times for the different active ingredients can range between a few and over 500 hours to reach the RT25 threshold. Even different formulations using the same active ingredient can have a significant difference in toxicity values. This illustrates the importance of reading the specific label instructions for a pesticide, even one that might be generally familiar to the user.
EPA’s publication of this information online also imposes a duty for EPA to continually update the table, especially to capture any changes in the information appearing in an earlier listing of the data. If, upon further review or later data submissions there are changes to the table for a product, EPA will need to alert users to potentially important changes in the information. Again, this illustrates the need for reading the label for each pesticide at the time of application, since some important information may have changed.

On August 28, 2017, the U.S. Environmental Protection Agency (EPA) announced the first of three feature and functionality updates to the Pesticide Submission Portal (PSP) expected this year. The portal is a web-based application allowing registrants to submit pesticide application packages to EPA electronically. The PSP application is accessed through EPA’s Central Data Exchange (CDX) Network which requires user registration.
This new PSP, version 1.4, release expands the feature to allow users to submit voluntary data related to specific registration review cases. Users can submit study citations, data matrices (Form 8570-35), cover letters and studies (protocols, study profiles, supplemental study data) using the new "Voluntary Submission" link on the PSP home page. This new release also allows users to resubmit previously submitted 90-day responses. Once a 90-day response or data submission has been successfully transmitted to the Office of Pesticide Programs (OPP), users may now modify responses to data requirements, cite additional studies, upload additional documents, and change how the product registration is supported. EPA states: “This action is another step in a phased approach that will ultimately lead to EPA’s ability to accept all pesticide applications electronically, a move that will help modernize the pesticide registration process, increase operational efficiencies and reduce paper waste.” EPA indicates that in addition to these changes, this update introduces enhancements and bug fixes.
EPA also released the OPP Pesticide Submission Portal (PSP) User Guide Version 1.4 which provides detailed instructions on how to use the PSP application and guidance on how to prepare a package for electronic submission.
Applicants using PSP need not submit multiple electronic copies of any pieces of their applications; EPA states that the requirement to submit multiple copies of data in Pesticide Registration Notice 2011-3 is applicable only to paper submissions. Pesticide registrants who previously submitted information via paper, CD, or DVD may instead use the portal and forego the courier costs of sending to EPA.
More information about the Electronic Submissions of Pesticide Applications is available on EPA’s website.

In an opinion issued on September 10, 2015, the U.S. Court of Appeals for the Ninth Circuit vacated the U.S. Environmental Protection Agency’s (EPA) unconditional registration for the pesticide sulfoxaflor and remanded the matter to EPA to obtain further studies and data regarding the effects of sulfoxaflor on bees and bee colonies. Sulfoxaflor is a new insecticide in the class of insecticides referred to as neonicotinoids, but its mechanism of action is distinct from other neonicotinoids. The Petitioners in this case were various trade organizations representing commercial beekeepers, as well as some individual beekeepers. The registrant Dow AgroSciences LLC (Dow) intervened in the action.
EPA granted an unconditional registration for sulfoxaflor on May 6, 2013, subject to a variety of risk mitigation measures, including a lower application rate, longer intervals between applications, and certain crop-specific label restrictions. EPA had previously proposed to issue a conditional registration for sulfoxaflor in January 2013, citing pollinator data gaps that could be addressed by requiring Dow to conduct and submit further studies. Under that proposal, use of sulfoxaflor would have been allowed at a reduced application rate during the time needed to complete data development. The court found that the subsequent decision by EPA to register unconditionally sulfoxaflor was not supported by substantial evidence, as required by Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Section 16(b), both because EPA failed to adhere to its own scientific methodology and because the rationale that EPA provided for granting an unconditional registration could not be reconciled with the analysis upon which EPA based its prior proposal to register conditionally sulfoxaflor.
EPA evaluated the potential risk to bees and bee colonies from sulfoxaflor use utilizing the Pollinator Risk Assessment Framework, a scientific risk assessment methodology developed after consultations between EPA, Canada’s Pest Management Regulatory Agency, and the State of California, and presented by EPA to the FIFRA Scientific Advisory Panel in 2012. The court found that the rationale provided for EPA’s unconditional registration decision could not be reconciled with findings that EPA itself made using this methodology or with the rationale EPA provided for its prior proposal to issue a conditional registration. EPA had decided it was necessary to proceed to Tier 2 of the pollinator risk assessment after reviewing risk quotients and residue data in Tier 1 of the assessment. EPA found the available data for Tier 2 to be insufficient to allow indefinite use of sulfoxaflor, even at a reduced application rate. The court could not reconcile this finding with the subsequent decision to grant an unconditional registration, even with the specified mitigation measures. The court found that “given the precariousness of bee populations, leaving the EPA’s registration of sulfoxaflor in place risks more potential environmental harm than vacating it.” The court stated that “EPA has no real idea whether sulfoxaflor will cause unreasonable adverse effects on bees, as prohibited by FIFRA.”
EPA argued that with a reduced application rate, the risk quotients and residue analysis in Tier 1 was “close enough” to sufficient to avoid the specified quantitative trigger for a Tier 2 analysis, thereby rendering any deficiencies in the available Tier 2 data irrelevant. The court effectively stated in response that close enough is not good enough, citing another recent Ninth Circuit decision in which a risk concern that is triggered by a margin of exposure less than or equal to 1000 was held to be triggered when the margin was exactly 1000. Thus, this court once again placed EPA on notice that it must follow its own methodology with precision, and that EPA cannot justify deviations from its own methodology by simply stating that it is exercising expert judgment.
This is an unusual case because the registration of a new pesticidal active ingredient has been vacated on substantive as opposed to procedural grounds. The court’s rationale reflects a lack of judicial deference to what EPA typically refers to as the scientific “weight of the evidence.” While the term itself does not appear in the opinion, the court is insisting that EPA must follow its standard methodology without allowing for any deviations based on professional judgment. Although in this instance the court has supported the position of opponents of pesticide use, judicial reluctance to accept scientific “weight of the evidence” conclusions could also make it harder for EPA to impose additional restrictions when new but inconclusive evidence appears.
This case could cause EPA to be more explicit in adding procedures to its standard analytic methodologies that allow deviations from the methodology based on professional judgment. The case could also cause EPA to reconsider its recent reluctance to avoid issuing conditional registrations and its preference for unconditional registrations for new active ingredients. In any case, decisions that afford EPA less discretion to use “weight of the evidence” reasoning when basing scientific conclusions on less than conclusive data or studies could have an impact on a number of EPA practices and policies involving interpretation of scientific data.

The release of the first Tier 1 assessments in the Endocrine Disruptor Screening Program (EDSP) by the U.S. Environmental Protection Agency (EPA) on June 30, 2015, is a significant bench-mark in the program since the original List 1 test orders were initially issued in October 2009. Fifteen of the original 67 List 1 chemicals were subsequently cancelled or discontinued by the respective pesticide registrants. The intended purpose of the Tier 1 screening was to identify potential interactions of the remaining 52 chemicals with three hormonal pathways (estrogen, androgen and thyroid) in the endocrine system. EPA evaluated the data from 11 screening assays (five in vitro and six in vivo), along with other scientifically relevant information (OSRI) comprised of existing toxicology studies and peer reviewed published literature, and drew preliminary conclusions about the potential of these 52 chemicals to disrupt endocrine functions. Importantly, EPA noted on the EDSP webpage that “a result indicating potential should not be construed as meaning that EPA has concluded that the chemical is an endocrine disruptor.”
The individually published weight-of-evidence (WoE) assessments and anticipated data evaluation records (DER) can be accessed online for the 52 chemicals involved in the Tier 1 screening assessment. EPA summarized its conclusions from EPA’s Tier 1 WoE assessments as follows:
- No evidence of potential interaction with any of the endocrine pathways was identified for 20 chemicals.
- Fourteen chemicals showed potential interaction with one or more pathways, but based on the available information, do not pose a risk for endocrine disruption.
- Eighteen chemicals showed potential interaction with the thyroid pathway, 17 of which also showed potential interaction with the androgen pathway, and 14 of which showed potential interaction with the estrogen pathway.
To explore further any potential adverse effects on the endocrine system that may be caused by the 18 chemicals that EPA categorized in the third group noted above, EPA has recommended the following Tier 2, multigenerational studies across various species for them:
- A comparative thyroid assay for four chemicals that EPA found to have potential interaction with the thyroid pathway in mammals;
- The Medaka Extended One Generation Reproduction Test, MEOGRT (Draft Test Guideline OCSPP 890.2200), for 13 chemicals that EPA found to have potential interaction with the estrogen or androgen pathways in wildlife; and
- The Larval Amphibian Growth and Development Assay, LAGDA (Draft Test Guideline OCSPP 890.2300), for five chemicals that EPA found to have potential interaction with the thyroid pathway in wildlife.
EPA has not yet issued its final Tier 2 non-mammalian Office of Chemical Safety and Pollution Prevention (OCSPP) test guidelines (890 Series). Public comment on the proposed guidelines closed on March 31, 2015. It is expected that the release of these remaining guidelines will signal the approach of the Tier 2 test orders, which EPA is likely to issue in 2016. Although a formal public comment period is not expected to be opened for the Tier 1 assessments, affected registrants should have the opportunity to respond directly to EPA regarding WoE assessments and forthcoming DERs.
This release of the Tier 1 WoE assessments, the anticipated release of Tier 2 test guidelines, along with EPA’s commitment to further the development of high-throughput (HTP) assays and computational tools will significantly influence the prioritization of List 2 chemicals in the EDSP and the timing of the List 2 test orders. The revised List 2 includes 109 chemicals for Tier 1 screening. As with List 1, List 2 candidates reportedly were selected based on EPA’s review concerning their possible presence in public drinking water and/or registration review status within EPA, and not because of their potential to interfere with the endocrine systems of humans or other species.

The Canadian province of Ontario has issued its final regulations under the Ontario Pesticides Act aimed at reducing the area planted with maize and soybean seed treated with neonicotinoid insecticides. These changes have been made as part of its broader strategy to protect pollinators, and aim to reach an 80 percent reduction in the number of hectares planted with neonicotinoid-treated corn and soybean seed by 2017.
The new rules create a new class of pesticides, known as “Class 12 pesticides.” This class applies to corn seed grown for grain or silage, and soybean seeds treated with the following neonicotinoid insecticides: imidacloprid; thiamethoxam; and clothianidin. The new regulations will not apply to popping corn, sweet corn, corn used for the production of seed, or soybean seeds planted for the purpose of producing a soybean seed crop of certified status.
The new system established by these regulations will take effect on July 1, 2015, and be phased in over time. The elements include but are not limited to the following:
- Integrated Pest Management Training: The regulations will require farmers to complete training on integrated pest management methods. To encourage participation, training will be offered for free until September 1, 2016; after that time, training will be provided at a cost. After August 31, 2016, any person (e.g., farmer) who purchases neonicotinoid-treated seeds will be required to have completed the integrated pest management training course and received a certification number, which will be valid for five years.
- Pest Assessment Reports: Farmers wanting to buy and plant neonicotinoid-treated seed on more than 50 percent of the total area of their corn and soybean crop will need to complete a pest assessment report and provide it to the sales representative or seed vendor from which they purchase the seeds.
- Requirements for Vendor Licenses for the Sale of Neonicotinoid-Treated Seeds: The regulations will require companies selling neonicotinoid-treated seeds to obtain a treated seed vendor’s license, notify purchasers that the seed is a neonicotinoid-treated seed, and offer untreated seed for purchase, among other requirements. Growers will only be able to buy and use neonicotinoid-treated seeds that vendors have put on the "Class 12 Pesticides List," a list updated by August of each year.
- Tracking of the Sale of Neonicotinoid-Treated Seeds: The regulations will require the annual submission of the sales of treated seeds “to ensure an open and transparent system to track progress.” The Ministry of the Environment will publicly report amalgamated sales and seed treatment data for neonicotinoid-treated corn and soybean seed.
The regulations do not include requirements for the transport and storage of Class 12 pesticides.
Further information is available at the below links:
It is important to consider these new requirements in conjunction with those being developed in the U.S. EPA’s approach to date in considering additional restrictions to neonicotinoid pesticides to protect pollinators appears to focus not as much on reducing the use of products, but instead on controlling and preventing unwanted exposure of pollinators to these products.
In recent weeks, the U.S. government issued a “National Strategy to Promote the Health of Honey Bees and Other Pollinators” on May 19, and on May 28, EPA released for comment: “EPA’s Proposal to Mitigate Exposure to Bees from Acutely Toxic Pesticide Products.”

Center for Food Safety v. EPA is a case in the U.S. Court of Appeals for the 9th Circuit (9th Circuit) that consolidates two petitions for review of a decision by the U.S. Environmental Protection Agency (EPA) to register the new herbicide product Enlist Duo for use in six Midwestern states. A group of non-governmental organizations filed one of the petitions and the Natural Resources Defense Council (NRDC) filed a separate petition. Enlist Duo combines the active ingredients glyphosate and 2,4-D. The registrant Dow AgroSciences (Dow) has intervened in the case. The petitioners focus primarily on the purported failure of EPA to consider properly the effects of Enlist Duo on certain endangered species.
Each petitioner has now filed a motion to stay the EPA action registering Enlist Duo due to Endangered Species Act (ESA) challenges. The first stay motion filed by NRDC is based primarily on the risk to monarch butterflies, and that stay motion has now been fully briefed. The other petitioners filed a separate stay motion focusing on whooping cranes and Indiana bats, but they waited until two weeks after EPA and Dow filed their briefs opposing the first stay motion. Before either stay motion was filed, Dow filed a motion seeking transfer of the case to the D.C. Circuit Court of Appeals. Arguing that the two independent successive stay motions were abusive, Dow later filed a motion to hold the briefing on the second stay motion in abeyance, pending a ruling on its transfer motion.
The 9th Circuit denied Dow’s motion to hold the briefing on the second stay motion in abeyance only three days later. This procedural ruling does not dispose of the underlying transfer motion, but it does suggest that the court is not inclined to transfer the case. If the case is not transferred, the court will ultimately consider and rule on both pending stay motions. The court’s interim order does not suggest how it views the pending stay motions. The petitioners have a heavy burden to show both a substantial likelihood of success on the merits and irreparable harm to obtain the requested interim relief. EPA and Dow contend that the petitioners have not established either of these things. Overall, this ESA challenge to a new genetically modified organism (GMO) product may indicate a new front in the ESA litigation arena, since new products have generally not been challenged under ESA requirements. 2,4,-D itself is not a new herbicide, so this case is not quite a challenge to a totally new active ingredient; such a challenge was made recently in the case of cyantraniliprole. CBD, et al. v. EPA, No. 14-00942 (D.D.C. filed Oct. 10, 2014). Challenges to new active ingredients and GMO products, however, could threaten to hinder the introduction of new products into the marketplace.
