On Friday, November 3, 2017, the California Department of Pesticide Regulation (DPR) issued guidance (California Notice 2017-13) that DPR indicates is intended to align DPR policy with the U.S. Environmental Protection Agency’s (EPA) guidance on secondary container labeling for pesticides.  DPR’s guidance states that secondary containers are used by the pesticide industry as part of the process of applying pesticides and “cannot be sold or distributed.”  The guidance further notes that secondary containers are “most commonly used in institutional settings for concentrated antimicrobials that are diluted prior to use or to hold pesticides filled from a larger container to be used and stored prior to application.” 

Registrants may elect to provide users with labels for secondary containers.  DPR’s new guidance states:  “Secondary container labels are not required to be submitted to U.S. EPA or DPR.”  Under the new DPR policy, however, effective immediately, if a registrant submits a secondary container label to DPR, “it must bear the same signal word as the concentrate label or no signal word.”  DPR states that it will accept a secondary container label with a lesser signal word, precautionary statements, and alternate directions for use for the diluted product only if acute toxicity data are submitted or are currently on file to support these lesser statements.

DPR’s new guidance also incorporates EPA guidance on what a secondary label should contain.  (EPA does not require secondary containers to be labeled, but notes that the applicator remains responsible for following the requirements on the pesticide product’s labeling, and complying with other relevant requirements in the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and other statutes.)  Although registrants are not required to submit secondary container labels to EPA for review, EPA recommends that the applicator identify the material in the secondary container in the event of a spill to ensure that adequate information regarding the pesticide can be obtained in case of a medical or environmental emergency.  EPA recommends that such labels include the following information:

  • Product name;
  • EPA registration number;
  • Name and percentage of active ingredient of the concentrated product or if known, the percentage of active ingredient in the end-use dilution;
  • If the product in the secondary container is diluted, it should be followed by the phrase:  “The product in this container is diluted as directed on the pesticide product label”;
  • The same signal word as the registered concentrate container label;
  • The same precautionary statements as the registered concentrate container label unless the registrant has acute toxicity data supporting lesser precautionary statements for the diluted product and alternate directions for the diluted product are indicated on the concentrate container label; and
  • The statement:  “Follow the directions for use on the pesticide label when applying this product.”

DPR states:  “If currently registered products have secondary container labels on file with DPR that do not meet the above criteria, registrants should submit revised labels to DPR as an amendment.”

Each submission must include:

  • California Application to Amend Pesticide Product (DPR-REG-035);
  • $25 application fee (payable to:  Cashier, Department of Pesticide Regulation);
  • A copy of the most current EPA stamp-accepted label;
  • Six copies of the concentrate container label; and
  • Six copies of the secondary container label.
    • If the precautionary statement on the secondary container label bears lesser precautionary statements, the submission must be accompanied by acute toxicity data or a reference to data on file with DPR.

As an alternative to submitting revised labels, registrants have the option of requesting that DPR rescind acceptance of the current stamp-accepted secondary container label previously submitted.  Registrants may submit their request in writing on company letterhead to their assigned Regulatory Scientist.  If a secondary container label is inconsistent with the DPR-approved label, DPR will consider the product misbranded, and DPR notes that misbranded products are subject to enforcement action.

Registrants that have previously submitted secondary labels to DPR should review the label in comparison to the DPR-approved concentrate container label and the requirements in this notice.  All inconsistencies must be corrected via amendment submission to DPR or by making a request that DPR rescind acceptance of the current stamp-accepted secondary label so that the product is not considered misbranded and therefore subject to enforcement action.

On September 22, 2017, the U.S. Environmental Protection Agency (EPA) issued a notice in the Federal Register (82 Fed. Reg. 44406) announcing the availability of two final Pesticide Registration Notices (PRN):

  1. PRN 2017-1:  Guidance for Pesticide Registrants on Pesticide Resistance Management Labeling, which updates PRN 2001-5 and provides guidance for registrants to follow when developing resistance management information to include on their pesticide labels.  It addresses “end-use herbicide, fungicide/bactericide, or insecticide/acaricide products that are intended mainly for agricultural and certain non-crop land areas under commercial or government-sponsored pest management,” and applies in particular to “all field use agricultural pesticide products, as well as pesticides which are labeled for greenhouse production, sod farms, ornamental crops, aquatic vegetation, rights-of way, and pest management along roadways.”
  2. PRN 2017-2:  Guidance for Herbicide Resistance Management Labeling, Education, Training, and Stewardship, which “communicates the agency's approach to address herbicide-resistant weeds.”  It is “germane to end-use herbicide products used in agriculture, including commercial turf and sod farms, ornamental production in the open.”  It also applies to “non-agricultural use sites such as golf courses, aquatic vegetation, rights-of-way and vegetation management along roadways.”

These final PRNs reflect consideration of public comments submitted on the draft PRNs.  Also available in the dockets are EPA’s responses to comments on the draft PRNs:  Response to Comments on PRN 2017-1; and Response to Comments on PRN 2017-2.  EPA states that “PRNs are issued by the Office of Pesticide Programs (OPP) to inform pesticide registrants and other interested persons about important policies, procedures, and registration-related decisions, and to provide guidance to pesticide registrants and OPP personnel.”

On September 19, 2017, the U.S. Environmental Protection Agency (EPA) announced an update to Chapters 15 and 16 of the Office of Pesticide Programs’ (OPP) Label Review Manual.  

Updates to Chapter 15: Company Name and Address, include removing non-label related instructions on submitting address change requests and updating the National Pesticide Information Center’s contact information, including new hours of operation.  Updates to Chapter 16: Graphics and Symbols, include adding hyperlinks to graphic and logo examples and allowing a QR (Quick Response) code as an acceptable symbol when used only for retail pricing.

EPA states that the Label Review Manual, which began as a guide for EPA label reviewers, serves as a tool to assist registrants in understanding the pesticide labeling process and assists registrants in understanding approaches for how labels should generally be drafted.  Pesticide product labels provide critical information about how to safely and legally handle and apply pesticides.  EPA directs registrants to submit questions or comments on the Label Review Manual by using its Pesticide Labeling Questions & Answers -- Form.

In a two-page order issued on April 10, 2017, the U.S. District Court for the Middle District of North Carolina granted in part a motion for summary judgment filed by “me-too” registrants, Willowood, LLC, Willowood USA, LLC, Willowood Azoxystrobin, LLC, and Willowood Limited (Defendants), regarding Syngenta Crop Protection, LLC’s (Plaintiff) claims of copyright infringement.  Syngenta Crop Protection, LLC v. Willowood, LLC, Case No. 1:15-CV-00274.  The claims at issue (Counts V and VI of Plaintiff’’s complaint) were based on the Defendants’ use of Syngenta’s label.  The court stated that it was granting this part of Defendants’ motion “because the Federal Insecticide Fungicide and Rodenticide Act (FIFRA) precludes copyright protection for the required elements of pesticide labels . . . of me-too registrants.”

Counts V and VI of Plaintiff’s complaint stated that Defendant copied and used substantial portions of Syngenta’s copyrighted work, and that this infringement is “willful and knowing.”  The Defendants’ motion for summary judgment stated with regard to the copyright infringement counts of the complaint:

  • Counts V and VI fail as a matter of law because Defendants’ labels comply with applicable federal regulations and contain language that is mandated by federal law.  Moreover, under settled law, the portions of Plaintiff’s labels that Plaintiff asserts Defendants have copied are not entitled to federal copyright protection.  Finally, to the extent that any portions of Plaintiff’s labels are entitled to copyright protection, Defendants’ copying is permitted under the fair use doctrine.  

The order states that “in enacting FIFRA, Congress intended narrow exception to copyright protection for the required elements of pesticide labels as against me-too registrants.”  The court expressly rejects the lengthy 2005 decision issued by the District Court for the Eastern District of Pennsylvania, which reached a different conclusion in a similar case, stating that it finds the analysis in that decision “unconvincing.”  FMC Corp. v. Control Solutions, Inc., 369 F. Supp. 2d 539, 555-71 (E.D. Pa. 2005).  The court states:  “FIFRA contemplates that a ‘me-too’ applicant will copy from the original pesticide label in ways that would otherwise infringe a copyright.”

Of interest, the court states that its grant of the summary judgment motion with respect to the copyright claims does not need to take into account an expert report or declarations by, among others, former EPA Office of Pesticide Programs (OPP) officials Debra Edwards and Lois Rossi, filed by Defendants because “the Court is granting the summary judgment motion on legal grounds unrelated to the proffered evidence.” 

Plaintiff filed its complaint on March 27, 2015.  The complaint included seven counts against Defendants:  the infringement of four patents in violation of 35 U.S.C. § 271(a) (Counts I-IV), the two copyright infringement counts (Counts V-VI), and a violation of the Unfair and Deceptive Trade Practices Act (N.C. Gen. Stat § 75-1.1) (Count VII).  Count VII of the complaint was dismissed on August 12, 2016, and on March 24, 2017, the court granted Plaintiff’s motion for summary judgment regarding the infringement of two of the four patents; a decision on the infringement of the remaining two patents is still pending.

Commentary

This opinion, which squarely rejects the 2005 conclusion of another district court, is likely to be of controversy and is the most recent decision in a long-standing debate on this issue between basic registrants and me-too registrants.  EPA in the past has appeared to side with the me-too registrants.  For example, in an August 3, 2005, letter to the Chemical Producers and Distributors Association (CPDA), written in response to the FMC decision, EPA stated that it “has been the practice of [OPP] since the enactment of FIFRA section 3(c)(7)(a) in 1978 to strongly encourage ‘me-too’ product labels to be identical or substantially similar to the labels of the products on which their registrations are based.”  In that letter, EPA stated further:  “Conveying application instructions and safety messages for similar products in different ways increases the likelihood that the product will be misused.”  EPA at the time noted that there were over 650 mostly “me-too” products for just one herbicide (2,4,-D) -- and that having 650 products each having to say some of the required use instructions differently would be impossible.

Nonetheless, some elements of the label might be viewed as proprietary -- the “look and feel” of a product label, perhaps certain fonts, and trademarked product name (as opposed to the active ingredient name).  It remains to be seen whether the April 10, 2017, order is the last judicial word on this subject or whether the issue will continue to be litigated.  It is an issue that all registrants should monitor closely.

On September 16, 2016, the U.S. Environmental Protection Agency (EPA) announced it settled an enforcement matter with Syngenta Crop Protection, LLC (Syngenta or Respondent) via a Consent Agreement and Final Order (CAFO) concerning EPA’s allegations that Syngenta violated the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and EPA’s Pesticide Container and Containment Rule (PCCR).  The investigation took place over three years, starting in August 2012 and concluding in January 2015.  The multi-regional investigation which took place over three years, from August 2012 to January 2015, was conducted by EPA Regions 4, 5, 7, and 8, and found violations in six states:  Ohio, Colorado, Iowa, Kansas, Michigan and Missouri.

The CAFO listed the alleged violations in three parts:

  1. Failure to have repackaging agreements and failure to maintain records concerning the repackaging agreements:  In the CAFO, EPA states that it identified numerous and separate occasions when Respondent distributed or sold approximately 19 registered pesticides to approximately 222 refillers “prior to having written repackaging agreements in place with such refillers,” “and/or failed to maintain records of the repackaging agreements with the refillers.”  The requirements for such agreements and record keeping are set forth at 40 C.F.R. §§ 165.67(b)(3), 165.67(d), and 165.67(h).
  2. Distribution and sale of misbranded pesticides:  In the CAFO, EPA states that at least seven inspections conducted at different facilities that were refillers of Respondent’s pesticides found pesticides affixed with outdated labels, as well as sales of such products with outdated labels.  EPA states that Syngenta was the registrant of all the products at issue and had provided the refillers with the outdated labels for repackaging the pesticide products in refillable containers or bulk tanks on at least 19 separate occasions.
  3. Failure to maintain data submitted for pesticide registration:  In the CAFO, EPA states it conducted an inspection at two laboratories to review compliance with Good Laboratory Practice requirements, and to audit the data for studies submitted by Respondent to EPA to support one of its pesticide registrations.  In both cases, Respondent informed EPA that it did not maintain records or raw data associated with the studies and the laboratories confirmed they did not maintain the records at their facilities.

Syngenta neither admits nor denies these allegations, but has agreed to pay a civil penalty of $766,508, as well as to complete an environmental compliance promotion Supplemental Environmental Project (SEP) within four years at a cost of not less than $436,990.  Specifically, the SEP will involve a four-year educational awareness training and campaign to educate the regulated community on FIFRA regulatory compliance requirements pertaining to the PCCR.  The training will focus on the requirements relevant to bulk pesticide containers, containment, labels, storage, transportation, delivery, clean-out, repackaging agreements, and recordkeeping.  The training is intended to increase awareness across a broad array of businesses that handle pesticides, including registrants, refillers, retailers, commercial applicators, and custom blenders of pesticides.

Discussion

EPA states that the settlement sends “a strong message to pesticide companies to maintain compliance with all federal environmental laws.”  Indeed, the breadth of EPA’s investigation and the ultimate size of the penalty signify EPA’s focus on pesticide violations and, particularly, misbranded pesticides.  EPA in recent years has focused on labeling violations between registrant and supplemental distributor labels and the issues in this case have some similarities, particularly the need for written contacts between registrants and refillers or supplemental distributors, and also the need to ensure that current pesticide labels are provided before repackaging and relabeling take place. 

More information concerning supplemental distributors and repackaging is available in our blog item Registrants Penalized for Actions of Third-Party Pesticide Distributor, our memorandum EPA’s Enforcement Efforts Regarding FIFRA Supplemental Distribution and How to Avoid Noncompliance and in the materials from our webinar EPA's Supplemental Distribution:  Enforcement Actions Are Buzzing:  How to Avoid Getting Stung.

The threat of the Zika Virus grows every day, and the need for clear information is especially pressing if you are pregnant.  How do you prevent getting infected with the Zika Virus, and what insect repellents are best?  The first question is easy to answer:  public health experts agree that women who are pregnant or who might be pregnant should use insect repellents.  The answer to the second question is not so simple.

I am a former senior official at the U.S. Environmental Protection Agency (EPA), and familiar with how the U.S. evaluates and approves pesticides, which include insect repellents.  It is not easy for the average consumer to know what works and what does not work.  Unfortunately, EPA policies have made this question much more complicated, having made important distinctions between some “natural”-type repellents and other products available in the marketplace.

Years ago, EPA de-regulated a number of natural, non-toxic materials from being subject to the registration requirements of the federal pesticide law (the Federal Insecticide, Fungicide, and Rodenticide Act).  This made sense at the time since garlic, pepper, rotten eggs, vinegar, and other common chemicals are sometimes used as pesticides.  Before de-regulation, these products were also subject to the same requirements as synthetic chemical pesticides with long unpronounceable names (e.g., diethyltoluamide, better known as DEET) which EPA requires to have volumes of efficacy and safety test data.  Being natural does not mean a substance is non-toxic; some natural ingredients are fully evaluated and widely used.  But in the interest of efficient use of resources EPA issued a list of products that could be sold as pesticides, but would not be subject to EPA data requirements and review (EPA calls them “minimum risk pesticides”).

This list of pesticides which are not subject to EPA evaluation, and which are not required to have data which proves they are effective, includes a number of botanical ingredients, such as oil of citronella, geranium, rosemary, peppermint, and many others.  Many of these products can be used as pesticides -- some may work better than others -- and many work for the intended use (example:  rotten eggs, or as EPA refers to them -- “putrescent whole egg solids” -- are used as a deer repellent).

Many of these ingredients have been marketed as “natural” insect repellents, and labeled as “safe” or “non-toxic” using words that will not appear on products where EPA reviews and approves the instructions on the product label.

Here is the bureaucratic distinction which matters greatly to EPA, but will not be understood by consumers:

  • If the repellant label includes “public health claims” -- that it repels mosquitoes that may cause a disease (like Zika Virus or West Nile Virus) -- then the product has to have data showing that it works;
  • If the product just says “repels mosquitoes,” it is not required to have data that shows it is effective, and may very well be ineffective.

Few, if any, humans outside of EPA label experts realize this important distinction:  if there is no health claim on the label, then it is, in effect, a situation of “buyer beware.” 

What remains:  EPA’s deregulation of these products means it is legal to sell products which do not work, as long as the ingredients appear on the EPA minimum risk pesticides list.

Consumer Reports (CR) recently reported in May of this year on studies conducted on repellents.  Their results:

  • Using a “natural” mosquito repellent, with active ingredients such as citronella or clove, lemongrass, or rosemary oils, might seem like a good idea, especially if you’re pregnant or planning to be.
  • But five of the six plant-based repellents we tested…lasted one hour or less against Aedes mosquitoes, the kind that can spread Zika.

Not all repellents with the same ingredient are equally effective, and they found that some formulations of the chemical repellents also do not work for very long in their tests.  Some botanical pesticides are effective and have the public health claims on the label (example:  lemon eucalyptus, a botanical ingredient not on the exempt product list, and CR testing did find it to be effective).

To reduce confusion about what works, EPA for years has struggled to correct the situation by trying to impose changes to the requirements for insect repellents.

Unfortunately, to end the confusion about the difference between “repels mosquitoes” and “repels mosquitoes that can cause the Zika Virus,” EPA has to conduct a rulemaking which requires a long and bureaucratic process to complete.  The good news is that EPA is working on such a solution.  The bad news is that they have been working on it for almost ten years and they still have more work to do.  There are details and petitions and proposals and reasons why it has taken so long, but it is the kind of story that gives bureaucracy a bad name.

With the onset and fears about the Zika Virus, however, EPA should make the needed changes immediately to ensure that consumers are not misled into using products which are not proven effective in repelling mosquitoes. 

From a consumer’s point of view, it really is that simple.  Legally, it is more complicated.  In the meantime, EPA should be loud and clear in its communication about the distinction, even if they cannot take immediate action to reduce the confusion.

On June 29, 2016, the U.S. District Court for the Northern District of California (Court) issued an opinion dismissing the complaint and denying the motion for summary judgment of the Center for Environmental Health, Beyond Pesticides, and Physicians for Social Responsibility (CEH, et al.), and granting the U.S. Environmental Protection Agency’s (EPA) motion for summary judgment. 

Background

This case stems from a petition filed in 2006 requesting EPA to initiate a rulemaking to require the labeling of 371 inert ingredients in pesticides.  EPA issued an Advance Notice of Proposed Rulemaking (ANPR) in 2009, but did not proceed further with a rulemaking.  CEH, et al. filed a second lawsuit in March 2014, alleging that EPA’s failure to complete the rulemaking process started by the ANPR violated the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the Administrative Procedure Act (APA).  In May 2014, EPA responded by amending its response to the 2006 petition to explain that it had decided to pursue an approach different from requiring mandatory disclosure on the pesticide label of a hazardous inert ingredient.  EPA announced that it would instead pursue a “‘combination of regulatory and focused non-regulatory actions that do not rely on rulemaking’ including potentially:  (1) removing over ninety chemicals from the list of inert ingredients approved for pesticide use; (2) evaluating the effect of the 371 inert ingredients on food crops; (3) directing pesticide registrants to modify their registrations by replacing hazardous inert ingredients with less hazardous ones; and (4) seeking to expand the existing voluntary disclosure program.”  The Court granted EPA’s motion for judgment on the pleadings in the March 2014 lawsuit, “finding that there was no further relief that [the Court] could offer to plaintiffs and that the action was moot.”

CEH, et al.’s complaint in the case at issue challenges EPA’s May 2014 denial of its rulemaking petition, alleging that under FIFRA and APA, EPA’s decision to deny the rulemaking petition was “arbitrary, capricious, and contrary to [FIFRA].”  CEH, et al. requested the court to “set aside the denial and to remand the decision to the EPA to consider ‘the evidence weighing in favor of disclosure of inert pesticide ingredients.’”  Background on the complaint is available in our blog item NGOs File Suit Regarding Inert Ingredients’ Disclosure.

In support of its ruling to grant EPA’s motion for summary judgment, the court stated:  “EPA is not mandated to require disclosure of the inert ingredients at issue,” since “[p]laintiffs have provided no persuasive evidence that EPA’s decision to forego rulemaking is inconsistent with the ANPR.”  The Court noted, for example, that EPA’s regulation governing disclosure of inert ingredients, 40 C.F.R. § 156.10(g)(7), states that “[t]he Administrator may require the name of any inert ingredient(s) to be listed in the ingredient statement if he determines that such ingredient(s) may pose a hazard to man or the environment”; this allows EPA to require applicants to list hazardous inert ingredients, but “does not mandate it.”  In addition, the Court found that EPA’s decision “that a series of non-rule actions would achieve a greater reduction in the risks from the use of pesticides and could be implemented in a timelier manner,” was not arbitrary or capricious, even if it “conceivably offers a less effective remedy than what plaintiffs sought.”

Discussion

The decision supports EPA’s discretionary authority to determine how to best manage and address any inert ingredients that may cause unreasonable adverse effects on the environment.  EPA has set forth several actions that it is taking or intends to take in lieu of mandatory label disclosure of inert ingredients.  For example, on October 22, 2014, EPA proposed to remove 72 chemical substances from the current listing of inert ingredients approved for use in pesticide products because the inert ingredients are no longer used in any registered pesticide product.  Registrants of any pesticides containing a potentially hazardous inert ingredient should monitor how EPA’s regulatory and focused non-regulatory actions affect such substances.

On June 7, 2016, the U.S. Environmental Protection Agency (EPA) announced that it was making two draft Pesticide Registration Notices (PR Notices) available for public comment:  (1) PR Notice 2016-X:  Draft Guidance for Pesticide Registrants on Pesticide Resistance Management Labeling; and (2) PR Notice 2016-XX:  Draft Guidance for Herbicide Resistance Management Labeling, Education, Training, and Stewardship.  In its news release, EPA states that it has started a “more widespread effort aimed at combating and slowing the development of pesticide resistance,” in an effort to “address the growing issue of resistance and preserve the useful life of pesticides.”

Draft PR Notice 2016-X

Draft PR Notice 2016-X, which revises and updates PR Notice 2001-5, applies to all conventional agricultural pesticides (i.e., herbicides, fungicides, bactericides, insecticides and acaricides).  The focus of the updates in PR Notice 2016-X is on pesticide labels and improving information about how pesticide users can minimize and manage pest resistance.  

Specifically, EPA is proposing that specific resistance-management statements be included with the Directions for Use section under the heading “Resistance Management Recommendations.”  EPA states that the proposed labeling statements “focus on the mitigation of pest resistance and should be used where applicable based on the availability of other pesticides and production practices specific to that crop.”  As one example, EPA recommends the following general resistance management labeling statements for insecticide/acaricide products containing only a single active ingredient or multiple active ingredients that are from the same Mode of Action (MOA) group:

  • For resistance management, (name of product) contains a Group (mode of action group number) insecticide (or acaricide). Any (insect/mite) population may contain individuals naturally resistant to (name of product) and other Group (mode of action group number) insecticides/acaricides. The resistant individuals may dominate the insect/mite population if this group of insecticides/acaricides are used repeatedly in the same fields.

Since the recommended resistance-management statements depend on an active ingredient’s MOA, PR Notice 2016-X also addresses MOA grouping and identification symbols for agricultural uses of herbicides, fungicides/bactericides, and insecticides/acaricides.  The pesticide groupings are provided by the Weed Science Society of America (WSSA), the Herbicide Resistance Action Committee (HRAC), the Fungicide Resistance Action Committee (FRAC) and the Insecticide Resistance Action Committee (IRAC).  The MOA groups, and the identifier numbers and/or letters (i.e., symbols or codes) for herbicides, fungicides/bactericides and insecticides/acaricides may be accessed through the websites of the different Resistance Action Committees.  For example, for insecticides, IRAC uses a combination of numbers and letters to identify various MOA groups.  EPA recommends that the IRAC MOA identifier codes be used for designating insecticide MOA grouping information on labels for pesticides containing insecticides.  The IRAC MOA list and identifier codes can be found online.

While current PR Notice 2001-5 contains similar guidance in terms of MOA groupings and general pesticide-resistance statements, the Draft PR Notice 2016-X provides:  (1) additional guidance, and recommended format, for resistance management statements or information to place on labels; (2) includes references to external technical resources for guidance on resistance management (e.g., professional scientific societies, resistance action committees for different types of pesticides); and (3) updates the instructions on how to submit changes to existing labels to enhance resistance management language.  In addition, while PR Notice 2001-5 states that “implementation of this program is purely voluntary by the pesticide industry,” the language in Draft PR Notice 2016-X is arguably stronger, with EPA “encouraging” registrants to add the appropriate resistance-management statements through notification, amendment, or as part of an application for a new product.

Draft PR Notice 2016-XX

Draft PR Notice 2016-XX, which only applies to herbicides, is intended to provide guidance on labeling, education, training, and stewardship for herbicides undergoing registration review or registration (i.e., new herbicide actives, new uses proposed for use on herbicide-resistant crops, or other case-specific registration actions).  EPA states it is focusing on the holistic guidance for herbicides first because:

  1. Herbicides are the most widely used agricultural chemicals;
  2. No new herbicide mechanism of action has been developed in the last 30 years; and
  3. Herbicide-resistant weeds are rapidly increasing.  In the future, the Agency plans to evaluate other types of pesticides (e.g., fungicides, bactericides, insecticides, and acaricides) to determine whether and what guidance may be appropriate for these types of pesticides.

Under guidance described in PR Notice 2016-XX, EPA proposes to divide 28 herbicide Mechanisms of Actions into three categories of concern (low, moderate, high) based on the risk of developing herbicide-resistant weeds.  Appendix I to PR Notice 2016-XX provides three tables with herbicide Mechanisms of Actions of “Low Concern,” “Moderate Concern,” and “High Concern” for herbicide resistance.  EPA states its intent to make these tables available on its website, noting that the tables would need to be “checked periodically to determine if there are changes to the groupings or level of concern categories.”  Appendix II to PR Notice 2016-XX sets forth the following eleven elements that are focused on labeling, education, training, and stewardship strategies:

  • Element 1.  List Mechanism of Action Group Number on label.
  • Element 2.  List seasonal and annual maximum number of applications and amounts.
  • Element 3.  Provide Resistance Management language from PR Notice 2016-X, and/or Best Management Practices language from WSSA and HRAC, and/or HRAC proposed guidelines for herbicide labels. Note that Best Management Practices (BMP) should be appropriate to crop and production system.
  • Element 4.  Instruction to user to scout before and after application.
  • Element 5.  Provide definition of Likely Resistance.
  • Element 6.  Instruction to user to report lack of performance to registrant or their representative.
  • Element 7.  List confirmed resistant weeds in a separate table and list recommended rates for these weeds with the table.
  • Element 8.  Registrant report new cases of likely and confirmed resistance to EPA and users yearly. This is in addition to any adverse effects reporting.
  • Element 9.  Provide growers with:
  1. Resistance Management Plan;
  2. Remedial Action Plan (to control resistant weeds this season or next season);
  3. Educational materials on resistance management; and
  4. Plans should be locally developed and easily modified. EPA recommends that registrants work with Extension, Consultants, Crop Groups, HRAC, and the U.S. Department of Agricultute (USDA).
  • Element 10.  For combination products with multiple Mechanisms of Action, list which herbicide is controlling which weed (a three-way mixture may only have one effective Mechanism of Action for some problem weeds).  List minimum recommended rate if resistance is suspected.
  • Element 11.  Any additional specific requirements (e.g., mandatory crop rotation, unique agronomic aspects, additional training, time limited registration, etc.).

Elements 1 through 4 are proposed for Mechanisms of Actions of Low Concern, elements 1 through 8 are proposed for Mechanisms of Actions of Moderate Concern, and elements 1 through 11 are proposed for Mechanisms of Actions of High Concern.

The PR Notices are available on www.regulations.gov under Docket Numbers EPA-HQ-OPP-2016-0242 for PR Notice 2016-X; and EPA-HQ-OPP-2016-0226 for PR Notice 2016-XX.  Comments are due by August 2, 2016

With regard to PR Notice 2016-XX, EPA states that while comments are welcome on all aspects of this Notice, EPA is especially interested in comments on the following: (1) the approach, elements and categorization used to address herbicide resistance; (2) limiting the application of these measures during registration review to new herbicide active ingredients, new uses of herbicides proposed for use on herbicide-resistant crops, and other case-specific registration actions; (3) other effective measures to inform the stakeholder community of the occurrence of likely resistance; and (4) other useful strategies that, when implemented, would slow the development of herbicide resistance and prolong the useful life of herbicides.

More information on pesticide resistance management is available on EPA’s website.

Avoiding the onset of resistance to any pesticide product is a widely shared goal of users and registrants of the pesticide to maintain the effectiveness and profitability of the product.  There is controversy, however, when EPA suggests specific instructions to the user community, since pesticide applications are site and situation specific, making general “one size fits all” approaches, even “flexible” ones, suspect among much of the user community.  When the instructions involve label requirements, which are enforceable, concerns about flexibility and the need to adapt to local conditions increase.

Resistance management has been a stated goal of EPA for some time; here EPA seems to argue it is of the utmost importance to preserve useful pest control tools since it is better to have more “tools in the toolbox.”  Yet, when EPA seeks to restrict a product or class of products and users and registrants cite the need for that product for resistance management, few benefits seem to be associated with resistance management in such cases.  Overall, there is also suspicion that EPA’s concerns regarding herbicide resistance masks a political response to critics of the widespread adoption of herbicide-resistant genetically engineered crops -- since the high value of resistance management gains little value when EPA attempts to restrict other products.  An example is EPA’s approach to organophosphate insecticides, where EPA is currently seeking to eliminate many uses that otherwise are viewed as important for insecticide resistance management.

Having EPA attempt to address resistance management via label instructions will be controversial, notwithstanding broad consensus that avoiding resistance is a shared goal.  So, the likely debate will focus less on the goal, and more on the means of achieving the goal, as this issue moves forward.

In response to the increasing concerns regarding emerging viral pathogens that are not on U.S. Environmental Protection Agency (EPA)-registered disinfectant labels, EPA announced on April 7, 2016, that it was updating its Guidance regarding emerging viral pathogens.  Under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), EPA is authorized to evaluate the efficacy of antimicrobial products intended to control pathogens that can be detrimental to public health.  Many believe that the process under which registrants can identify “effective disinfectant products for use against emerging pathogens,” and the process for EPA to “permit registrants to make limited claims of their product’s efficacy against such pathogens,” have not been clear and efficient.  EPA notes, for example, that “[emerging] pathogens are often unavailable commercially, and standard methods for laboratory testing may not have been developed,” such that it “can be difficult to assess the efficacy of EPA-registered disinfectants against such pathogens in a timely manner and to add these viruses to existing product registrations.”

EPA hopes that its Guidance will “expedite the process for registrants to provide useful information to the public” regarding products that may be effective against emerging viral pathogens associated with certain human or animal disease outbreaks.

EPA’s new draft Guidance document, Draft Guidance to Registrants:  Process for Making Claims Against Emerging Viral Pathogens Not on EPA-Registered Disinfectant Labels, describes “a voluntary two-stage process to enable the use of certain EPA-registered disinfectant products against these emerging viral pathogens, uses not previously identified on the product label”:

  • First Stage:  This stage may be performed prior to any outbreak. EPA summarizes the first stage as follows:  “registrants with an eligible disinfectant product may submit a request, via label amendment, to add a designated statement to the master label and additional terms to the product registration.  If the product meets the eligibility criteria suggested in this Guidance, [EPA] generally will approve the amendment.  Approval of the amendment would include additional terms and conditions of registration regarding how the designated statement may be published and communicated.”
  • Second Stage:  This stage would occur only during a human or animal disease outbreak caused by an emerging virus.  EPA summarizes this stage as follows:  “In this stage, registrants of products with the previously mentioned label amendment and terms of registration would be allowed to use the designated statement in off-label communications intended to inform the user community/public that the disinfectant product(s) may be used against the specific emerging viral pathogen.  These off-label statements can inform the public about the utility of these products against the emerging pathogen in the most expeditious manner and can be more easily removed once the outbreak has ended than statements on a label.”

Comments related to clarity of this Guidance will be accepted until May 6, 2016.  For more information, please see our memorandum EPA Announces Updated Guidance for Antimicrobial Pesticide Products Intended to Combat Emerging Pathogens.
