Group Working on Almond Transition Strategy

The Almond Board of California hosted a workshop October 28-29 in Bakersfield, California, to address the critical pest management needs that may arise in California almond production as a result of the Food Quality Protection Act (FQPA). The 20-member work group, with OPMP's Wilfred Burr serving as facilitator, is developing a transition strategy to deal with the potential loss of organophosphate insecticides.

Participants were asked to keep several factors in mind--that proposals must support producer's profitability; that within California there are unique production areas with diverse pests and a variety of climatic conditions; and that almond varieties and production practices often vary. The desired outcome of this process is ultimately a "To Do" list of research, regulatory relief and education to support almond growers.

Participants included growers, land-grant university faculty, pest control advisors, farm advisors, and EPA, USDA and commodity representatives ‹ a composition similar to prior work groups that addressed California peaches and mid-Atlantic/Appalachian/Southeastern apples. In each case, a summary guidance document is drafted by the OPMP and reviewed by workshop participants before being made available as a public resource. The apple transition document currently is available at http://www.epa.gov/pesticides/trac/10-20doc.htm.

Similar efforts are being planned for Southeastern peaches, Northwest pome fruits and other commodities. This office welcomes your suggestions about the reports as well as implementation of the recommendations.

IR-4's Efforts Lead to Registration of Bifenthrin on Minor Crops

Bienthrin, a synthetic pyrethroid insecticide, has been registered recently for use on brassica vegetables (cabbage, broccoli, cauliflower, etc.), cucurbits, edible-podded legumes, succulent shelled peas and beans, globe artichoke, canola and sweet corn. Data to support all of these tolerances, except sweet corn, was generated by the USDA Inter-regional 4 (IR-4) Project. EPA gave bifenthrin submissions high priority because many of the proposed uses were classified as organophosphate alternatives. The future looks bright for more bifenthrin registrations on minor crops. IR-4 recently submitted petitions to EPA proposing bifenthrin tolerances on head lettuce, bell and non-bell peppers, and the caneberry crop subgroup. Within the next two years, IR-4 plans to submit petitions proposing tolerances on the herb crop subgroup, and for celery, spinach and mustard greens. New residue studies for bifenthrin uses on tomato and cilantro will begin in 2000. Bifenthrin is produced by FMC Corporation and marketed as Capture®, Brigade® and Talstar®. For more information contact Ken Samoil at IR-4 Headquarters: 732-932-9575x614 or samoil@aesop.rutgers.edu--submitted by Sandy Perry, IR-4 outreach specialist.

Mitigating Herbicide Risks: Analysis Continues on Buffer Zones

The EPA Office of Pesticide Programs is developing a standard approach for calculating buffer zones (the distance to maintain between a pesticide application site and sensitive nontarget areas). With this approach, a spray drift model called AgDRIFT is used to determine the distance necessary for spray drift deposits to fall below a certain level. For herbicides, it is the level that causes up to a 25% reduction in plant growth in laboratory tests. Typically, 10 species of crop plants covering a range of taxa are tested, and EPA uses the 25% value for the most sensitive species in its assessment.

The Spray Drift Task Force, a registrant group, made a preliminary analysis of theoretical buffer sizes calculated by EPA for 28 herbicides. The herbicides represent multiple classes of chemistry and modes of action. For ground applications made with a low spray boom (2 ft. above ground), about 20% of the compounds required a buffer less than or equal to 50 feet, while 70% required buffers of greater than 150 feet, and 15% needed buffers of 450 to 1,000 feet. For aerial applications, the theoretical buffers are larger. Only one of the 28 compounds examined could get by with a buffer of less than 50 feet, while 75% of the compounds required buffers of 450 to 1,000 feet.

These calculations are based on several worst-case assumptions. Discussions are ongoing between the SDTF and EPA concerning ways to better reflect more representative conditions.

OPMP Monthly

About This Issue
This issue (Oct. 29, 1999) comes delayed but with plenty of informative news. The delay reflects the time taken by our communications director, Suzanne Deatherage, to move back and settle in at her job with the Texas Agricultural Extension Service. Suzanne had relocated to work six months on an interagency personnel assignment here at the Office of Pest Management Policy. Now she'll continue some OPMP work on a part-time basis from Texas. For a direct "howdy," call Suzanne at 409-845-3789. For e-mail, use s-deatherage@tamu.edu.--Dr. Allen Jennings, Director, USDA Office of Pest Management Policy.

Each OPMP Monthly may contain several notifications and may have been modified to highlight pertinent information for the Western Region. Additional information will be included when relevant.

TRAC: Last Meeting; Lasting Impact

The seventh and final meeting of the Tolerance Reassessment Advisory Committee, Oct. 20-21, provided an opportunity for discussion about the year-long pilot process that has involved USDA and stakeholders in the review of EPA organophosphate risk assessments--a TRAC-supported effort that has produced a lasting improvement in the transparency of the regulatory process. In light of the pilot experience, questions include: whether to adopt the current pilot as the final process; whether to modify, eliminate or expand certain phases; whether to enhance public involvement or interagency governmental review earlier in the process; and whether to use the same process for tolerance reassessment and reregistration of pesticides other than the OPs. To learn more, see the TRAC web site at .http://www.epa.gov/pesticides/trac/10-20doc.htm.

Transition Report Released for Apple Production Region
Also presented at the TRAC meeting was the recently completed USDA report on pest management "transition" needs for apple production in the Mid-Atlantic, Appalachian and Southeastern region. The report takes a pest-by-pest approach to anticipating needs that are developing in the wake of the Food Quality Protection Act. The report is posted on the EPA web site as part of the background materials for last week's TRAC meeting.

Similar reports are being prepared or planned for California peaches, Southeastern peaches, California almonds, Northwest pome fruits and other commodities. This office welcomes your suggestions about the report as well as implementation of the recommendations.

Budget: New FQPA Programs Funded; Long-time Program Changed

Just signed by the President, the FY2000 USDA budget includes $5 million dollars for two new programs supported by this office: $1 million for the Crops at Risk (CAR) program and $4 million for the Risk Avoidance and Mitigation Program (RAMP). Both pertain to implementation of the 1996 Food Quality Protection Act and both will be administered through the budget's new "Integrated Activities" fund. Allocations from this fund may be made only via competitive grants, as provided by Section 406 of the 1998 Agriculture, Research, Extension, and Education Reform Act.

The national Pesticide Impact Assessment Program (PIAP), as well as the Food Safety and Water Quality Programs, were shifted to the Integrated Activities account. So future funding for these programs must be sought through competitive grants; however, upstart on the request-for-proposals (RFP) process may take many months.

Here at the Office of Pest Management Policy, PIAP personnel have been essential partners in the USDA review of EPA pesticide risk assessments and in the development of crop profiles and commodity transition plans. The Department remains committed to continuing these activities. OPMP and Cooperative State Research, Education and Extension Service are working on options to maintain the PIAP network during the conversion to competitive grants funding.

FY 2000 funding remained level for IPM, IR-4 (minor crops) and the Pest Management Alternatives Program (PMAP). The Pesticide Data Program received $1.487 million and $911,000 more for FQPA support and water sampling, respectively. The National Agricultural Statistics Service received new allocations of $2.5 million, $800,000 and $250,000 for fruit and vegetable surveys, a nursery crop survey and a new Puerto Rico office, respectively. For new FQPA implementation activities, the Agricultural Research Service received $250,000.

Below is a recap of the CAR and RAMP programs. Watch the OPMP Monthly for an announcement when the RFP is ready.

IR-4 Symposium Addresses Future Approaches
to Minor Crop Pest Management

IR-4, the USDA-supported group that develops pest control registrations for minor crops, hosted its state and commodity liaisons, regional and headquarters staff, as well as CSREES, ARS and EPA cooperators in Washington D.C., October 4-7. The symposium focused on three topics:

Each topic was followed by discussion groups whose comments were collated for consideration in updating IR-4's strategic plan.

IR-4 staff also demonstrated a newly expanded and updated web site. It is now possible to find the status of 200+ current IR-4 research projects involving pesticides and biopesticides on food crops and ornamentals. Other links identify products that already have been submitted to EPA for registration, new clearances listed by pesticide and by crop, cumulative clearances, new pesticide chemistries, and an electronic version of the Pesticide Clearance Request form. Ready access to this information should facilitate the pest control transition strategies needed for the Food Quality Protection Act.

To subscribe to the IR-4 Newsletter, contact Prof. George Markle at IR-4 Headquarters (732-932-9575x606) or markle@aesop.rutgers.edu. --submitted by Sandy Perry, IR-4 Outreach Specialist.

EPA Receives Expanded Grant Authority

Past grants from the EPA Office of Pesticide Programs have supported research projects only, because of the narrow authority stated in Section 20 of the Federal Insecticide, Fungicide and Rodenticide Act.

However, new FIFRA wording is included in the EPA fiscal year 2000 appropriation and will apply to future pest management grants. The provision states that "...beginning in FY 2000 and thereafter, grants awarded under Section 20 of the Federal Insecticide, Fungicide, and Rodenticide Act, as amended, shall be available for research, public education, training, monitoring, demonstrations, and studies."

The Status of OPs in Review

The organophosphate risk assessments currently in review by USDA and the land-grant universities are oxydemeton methyl, dimethoate and ethyl parathion. Comments were received from reviewers and sent to EPA for another OP, methidathion. These comments are to be evaluated and a response sent to USDA before EPA's revised risk assessment is released to the public. In place of a technical briefing, EPA will hold a stakeholder meeting for methidathion and oxydemeton methyl in California sometime in very early December. After that meeting the revised risk assessments will be released to the public for comment on risk management measures.

EPA Turns Toward Tolerance Reassessment of Non-OPs

Pesticides other than organophosphates are coming up for reregistration eligibility decisions (REDs) by the U.S. Environmental Protection Agency. Unlike organophosphates, non-OPs are subject to a scheduling procedure that pre-dates the Food Quality Protection Act (FQPA) and does not include OP-type reviews and comment periods.

While revisions to the RED scheduling procedure for non-OPs are likely, EPA has not officially published or announced them. The current schedule starts collecting use and usage information from registrants early in the RED development. Real world data are essential for regulatory decision-making and are particularly needed when the RED is being refined.

This fall EPA will make several reregistration decisions for non-OPs, including the products listed below. To inform EPA of any critical uses you have for a product, contact the product's chemical review manager, who also is listed.
