We are affirming our earlier determination that it was necessary to immediately add to the Plant Protection and Quarantine Treatment Manual a treatment schedule for methyl bromide fumigation of cottonseed for the fungal plant pathogen Fusarium oxysporum f. sp. vasinfectum (FOV). In a previous notice, we made available to the public for review and comment a treatment evaluation document that described the new treatment schedule and explained why we have determined that it is effective at neutralizing FOV, certain strains of which are quarantine pests.


Effective Date: Effective on March 6, 2013, we are affirming the addition to the Plant Protection and Quarantine Treatment Manual of the treatment described in the notice published at 77 FR 31564-31566 on May 29, 2012.

The regulations in 7 CFR chapter III are intended, among other things, to prevent the introduction or dissemination of plant pests and noxious weeds into or within the United States. Under the regulations, certain plants, fruits, vegetables, and other articles must be treated before they may be moved into the United States or interstate. The phytosanitary treatments regulations contained in part 305 of 7 CFR chapter III (referred to below as the regulations) set out standards for treatments required in parts 301, 318, and 319 of 7 CFR chapter III for fruits, vegetables, and other articles.

In § 305.2, paragraph (b) states that approved treatment schedules are set out in the Plant Protection and Quarantine (PPQ) Treatment Manual.[1] Section 305.3 sets out a process for adding, revising, or removing treatment schedules in the PPQ Treatment Manual. In that section, paragraph (b) sets out the process for adding, revising, or removing treatment schedules when there is an immediate need to make a change. The circumstances in which an immediate need exists are described in § 305.3(b)(1). They are:

  • PPQ has determined that an approved treatment schedule is ineffective at neutralizing the targeted plant pest(s).
  • PPQ has determined that, in order to neutralize the targeted plant pest(s), the treatment schedule must be administered using a different process than was previously used.
  • PPQ has determined that a new treatment schedule is effective, based on efficacy data, and that ongoing trade in a commodity or commodities may be adversely impacted unless the new treatment schedule is approved for use.
  • The use of a treatment schedule is no longer authorized by the U.S. Environmental Protection Agency or by any other Federal entity.

In accordance with § 305.3(b), we published a notice [2] in the Federal Register on May 29, 2012 (77 FR 31564-31566, Docket No. APHIS-2012-0040), announcing our determination that a new methyl bromide fumigation treatment schedule to neutralize the fungal pathogen Fusarium oxysporum f. sp. vasinfectum (FOV) on cottonseed (Gossypium spp.) is effective, based on evidence presented in a treatment evaluation document (TED) we made available with the notice. We also determined that ongoing trade in cottonseed would be adversely impacted unless the new treatment schedule is approved for use. The treatment was added to the PPQ Treatment Manual, but was subject to change based on public comment.

We solicited comments on the notice for 60 days ending July 30, 2012. We received four comments by that date. Three commenters supported the addition of this treatment to the PPQ Treatment Manual. The other commenter objected to the use of methyl bromide fumigation in general but did not present any evidence indicating that the treatment schedule described in the TED was not effective at neutralizing FOV on cottonseed.

Therefore, in accordance with the regulations in § 305.3(b)(3), we are affirming our addition of a methyl bromide treatment schedule to neutralize the FOV, as described in the TED made available with the previous notice. The treatment schedule is numbered T301-e. The treatment schedule will be listed in the PPQ Treatment Manual, which is available at the Web address and mailing address in footnote 1 of this document.
