Environmental Protection Agency (EPA).


Notice of availability.


The Agency is announcing the availability of a Pesticide Registration Notice (PR Notice) entitled “Labeling Statements on Products Used for Adult Mosquito Control.” This PR Notice was issued by the Agency on insert date PR Notice was signed by the OD and is identified as PR Notice 2005-1. PR Notices 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 serve to provide guidance to pesticide registrants and OPP personnel. This particular PR Notice provides guidance to the registrant concerning EPA's policy on labeling statements for pesticide products used for wide-area applications to control adult mosquitoes. The specific label statements and label organization principles recommended in the draft Notice are intended to improve existing labels by clarifying language conveying environmental hazards posed by these products, as well as specific use directions and instructions to the applicators. The Agency believes that adoption of these recommendations will help pesticide users and pesticide enforcement officials to achieve more effective mosquito control and protection of public health, while ensuring that use of these products will not pose unreasonable risks to the environment.

I. Does this Action Apply to Me


This action is directed to pesticide registrants, pesticide regulatory officials, mosquito and vector control agencies, pesticide users and the general public. Although this action may be of particular interest to those persons who have a specific interest in the labeling of pesticide products used for the control of adult mosquitos, the Agency has not attempted to describe all the specific entities that may be affected by this action. If you have any questions regarding the information in this notice, consult the person listed under FOR FURTHER INFORMATION CONTACT.

II. What Guidance Does this PR Notice Provide?

This PR Notice provides guidance to the registrant concerning seven specific recommendations for labeling statements to be used on pesticide products used for control of adult mosquitos through ground or aerial application of Ultra-Low Volume (ULV) sprays or fogs.

A. Background

In recent years state pesticide regulators and vector control agencies have raised a variety of concerns about the labeling of pesticides used for adult mosquito control. The class of products of most concern have been those used for control of adult mosquitoes through the application of Ultra-Low Volume (ULV) sprays or fogs. Since state agencies enforce pesticide use regulations under cooperative agreements with EPA, and since FIFRA section 12(a)(2)(G) makes it an unlawful act “to use any registered pesticide in a manner inconsistent with its labeling”, the interpretation of label requirements is a critical issue for EPA, its Regional Offices and state pesticide regulatory agencies, as well as for users.

In 2001, EPA sponsored an Inter-Regional Mosquito Control Conference for EPA and state agency representatives. Although labeling was one of many subjects discussed at the conference, participants felt label improvements were an area that should be addressed. It was agreed that a group representing EPA's Office of Pesticide Programs (OPP), Office of Enforcement and Compliance Assurance (OECA), EPA Regions and state lead agency volunteers would develop initial, informal proposals for improving mosquito control product labels, with the focus on adulticides only. The EPA State workgroup developed a paper which included seven recommendations. In April 2003, the initial recommendations were discussed at a public meeting of the Pesticide Program Dialogue Committee (PPDC). The PPDC is chartered under the Federal Advisory Committee Act to advise EPA on pesticide issues. Its members represent a broad spectrum of interests, including the pesticide industry, grower groups, public health agencies, academic researchers, public interest and advocacy organizations. The PPDC recommended that EPA develop the initial recommendations into more formal Agency positions.

After considering the comments and suggestions of state agencies, the PPDC and other interested parties, as well as public comments received on a draft version of the PR Notice, the Agency is making the recommendations in the PR Notice as a means to achieve improvements in the labeling of adult mosquito control products. The Start Printed Page 12882recommendations consist of some specific statements that should appear on all labels for this class of products, some model statements that registrants may adapt to the specific characteristics of their products, and some principles on organizing elements of the label.

B. Summary of the Labeling Recommendations

The recommendations in the PR Notice are meant to apply only to products labeled for wide-area application by ground or aerial equipment, as Ultra Low Volume (ULV) sprays or fogs, and not to home and garden use products which may list mosquitoes on the label, or for coarse (non-ULV) sprays intended for residual treatment of vegetation or other surfaces. Control of mosquito larvae is a wholly different use pattern from adult mosquito control, and thus, products registered as mosquito larvicides are not included in the scope of the Notice.

The PR Notice sets forth seven recommendations for improving labels of adult mosquito control products. In brief form, the recommendations are:

1. Adult mosquito control applications should be limited to trained personnel.

2. Mosquito control directions and precautions should be clearly distinguished from those applicable to any other use allowed on the label.

3. Label precautions and directions should be revised as needed to make hazards to aquatic life as clear as possible, and also to allow the application of these products over a body of water allowable under some circumstances.

4. Users should consult with the State or Tribal lead agency for pesticide regulation to determine if permits or other regulatory requirements exist.

5. Labels should specify a spectrum of spray/fog droplet sizes, and indicate that droplet size should be determined according to directions from equipment manufacturers or other appropriate sources.

6. Precautionary language to protect bees should have a provision to allow mosquito control applications in order to respond to threats to public health which are identified by health or vector control agencies on the basis of evidence of disease organisms or diseases cases in animals or humans.

7. Mosquito adulticide labels should include specific statements on timing and allowable frequency of applications to a specific site. Exceptions to application limits may be allowed in order to respond to threats to public health which are identified by health or vector control agencies on the basis of evidence of disease organisms or diseases cases in animals or humans.

III. Do PR Notices Contain Binding Requirements?

The PR Notice discussed in this notice is intended to provide guidance to EPA personnel and decision makers and to pesticide registrants. While the requirements in the statutes and Agency regulations are binding on EPA and the applicants, this PR Notice is not binding on either EPA or pesticide registrants, and EPA may depart from the guidance where circumstances warrant and without prior notice. Likewise, pesticide registrants may assert that the guidance is not appropriate generally or not applicable to a specific pesticide or situation.
