BRIEFS (10/1/02)
CONTENTS:
EPA examined the monitoring data used in the OP cumulative risk assessment and found that pesticide residue was detected only in an insignificant number of the samples that were analyzed for these food commodity/OP combinations, including the parent chemical and the degradates that were tested. In addition, the revised OP cumulative risk assessment indicates that relatively few pesticide/crop combinations account for the vast majority of exposure. These tolerances are not among those pesticide/crop combinations that are major contributors to risk. Federal Register notices further describing these actions will be published soon. EPA has previously announced similar reassessment decisions. Information on these reassessments is available at http://www.epa.gov/pesticides/cumulative/tolerance.htm ; see "Reassessment of Diazinon Non-Contributor Tolerances" and "Reassessment of More Non-Contributing Commodity Tolerances." EPA expects that additional tolerances will be appropriate for reassessment based on the kind of approach described in this Notice. RETURN TO TOP

STEWARD ON SOYBEANS - JOANNE WHALEN, 24 AUG 2002
BEET ARMYWORM populations are variable and there are fields with high numbers. Next week will tell a better story. Most of the pressure is in Sussex County but I have seen fields with high populations as far north as southern Kent County. As far as Steward, data shows very good control of EARWORM and beet armyworm. Although the label says 5.6 to 11.3 ounces, the rate DuPont feels the best at for mixed size beet armyworm is 7.2 ounces so that is what we should go at in most cases. Ames Herbert and Dupont have some good data at 5.6 ounces but I think we should recommend 7.2 since that is what DuPont is supporting. If you have any questions, let me know. I hope the cooler weather predicted for next week slows things down since there was a lot of egg laying going on through yesterday. Regards,

PESTICIDE SECURITY ADVISORY
The U.S. Department of Justice, through
Sandia National Laboratories, has developed a chemical facility vulnerability
assessment methodology (VAM). The VAM is a tool which chemical facilities
may apply to assess their security vulnerabilities and to assist decisions
regarding how to appropriately address those vulnerabilities. A report
detailing the VAM can be accessed on the National Institute of Justice's
website at:
The American Chemistry Council (ACC) with the Synthetic Organic Chemical Manufacturers Association and the Chlorine Institute have produced a chemical site security guideline document and a chemical transportation security guideline document. Both documents are available on the ACC website at: http://www.Americanchemistry.com/ The Center for Chemical Process Safety (CCPS) has released, "Guidelines for Analyzing and Managing the Security Vulnerabilities of Fixed Chemical Sites." This book is intended for chemical site managers, process safety managers, security managers and others responsible for conducting security vulnerability analyses and managing security at fixed chemical sites. To request a copy of this document visit the CCPS website at: http://www.djbassoc.com/CCPSregister.asp If you have questions regarding this advisory or EPA's Pesticide Security Alert, please contact Dennis Deziel of EPA's Office of Prevention, Pesticides, and Toxic Substances at (202) 564-0331 EPA has issued the final Pesticide Registration (PR) Notice identifying pests of significant public health importance. A Notice of Availability of the PR Notice was published in the Federal Register on September 11th. Section 28(d) of FIFRA requires EPA, in coordination with the U.S. Department of Health and Human Services and USDA, to identify pests of significant public health importance. Before publishing the list, EPA and coordinating agencies used reviews by experts in public health and pesticide use patterns to compile the list. Public comments were also considered in developing the list. The publication of the list does not affect the regulatory status of any registration or application for registration of any pesticide product. EPA and coordinating agencies do not envision this list will remain static since it is possible that additional species may be found to present public health problems. As deemed necessary, EPA will update the list of pests of significant public health importance. Interested parties are invited to petition the Agency regarding the amendment of this list. The PR Notice (PR Notice 2002-1), which includes the full list of pests of significant public health importance, may be found on EPA's website at http://www.epa.gov/opppmsd1/PR_Notices/pr2002-1.pdf .

USDA's National Agricultural Statistics Service (NASS) has published chemical use statistics through a new website developed by North Carolina State University's Center for IPM. Data users can now search agricultural chemical usage data based on crop, year, region, or active ingredient. Users can also extract various chemical usage statistics from previously published data and create maps or descriptive charts based on these data. Data are currently available for crop years 1990 to 2001. NASS began collecting chemical usage statistics in 1990 in response to food safety and water quality concerns raised by consumers and congressional initiatives passed to address these concerns. Crops and states surveyed each year change based on evolving program needs and budgeted resources. Information on the chemical use program, by year, is available on the website. These data can be accessed either by going to the NASS homepage at http://www.usda.gov/nass/ and clicking on the "Ag Chem Database" icon or by going directly to the USDA Regional Pest Management Center's National Database Website at http://www.pestmanagement.info/nass . The sites also have information on contacts for technical and subject matter related questions. EPA has received several inquiries from state pesticide regulatory agencies regarding the use of METHOPRENE granular and briquet products for MOSQUITO CONTROL if the application site is an ANIMAL WATERING TROUGH. Labels on these products have some relatively vague language on use sites, such as "water-holding recepticles...other containers" and "other artificial water-holding containers". The EPA/OPP product manager, noting that methoprene is also registered as a feed-through pesticide for control of flies in livestock manure, and has established tolerances for that use, concluded, after consulting with staff in the Office of Enforcement and Compliance Assurance, that an animal watering trough is an allowable site for the use of methoprene granules and briquets for mosquito control. EPA is clarifying an enforcement position whereby it would not be considered use inconsistent with the label to use a pesticide in a GREENHOUSE as long as the crop site [e.g., tomato] is listed on the label and there are no restrictions or prohibitions regarding use in a greenhouse. When EPA publishes this position, I will post it here at Pesticide Briefs. According to the Registration Division, data for all registrations are reviewed to determine if greenhouse use is acceptable and whether additional label precautions or application restrictions are necessary to allow greenhouse use. If greenhouse use is deemed unacceptable, then this prohibition is required to be added to the label. Although there are some products that have not been reviewed according to this policy, most products have been. It's felt that those that were not do not constitute a significant risk concern, so they've been "grandfathered" in with the assumption that they will be caught during reregistration and brought up to current science and labeling standards at that time. Products without specific directions for greenhouse use would not likely have directions in terms of application rates [e.g., ounces per row], and would not have a REI specific for greenhouses.

EPA will phase out and cancel certain crop uses and formulations of the insecticide DIAZINON to reduce risks to birds and other wildlife, agricultural workers, and the environment. These actions are part of a second agreement between EPA and diazinon technical registrants, reflected in the Diazinon Interim Reregistration Eligibility Decision (IRED) signed by EPA on 7/31/02. All indoor use product registrations must be canceled and retail sale must end by 12/31/02 and all outdoor residential use product registrations must be canceled and retail sale must end by 12/31/04. Other mitigation includes canceling nearly all granular uses, discontinuing all aerial applications, discontinuing foliar application to nearly all vegetable crops, reducing the number of applications per growing season for most uses, requiring engineering controls for mixers and loaders, and closed cabs for applicators, setting reentry intervals at 2-18 days, and canceling certain crop uses.

On 7/31/02, EPA completed the Reregistration Eligibility Decision (RED) document for ENDOSULFAN (Thiodan). This document reflects the risk management and tolerance reassessment decision for this pesticide. Endosulfan is used on a wide variety of vegetables, fruits, cereals, and cotton, as well as ornamental greenery in agricultural settings. EPA has identified measures to reduce the exposure to endosulfan from food, water, and occupational sources, and exposures to non-target organisms. These measures include canceling uses for succulent bean, succulent pea, grape, pecan, and spinach; reducing application rates; and establishing set backs and buffers to protect water. While EPA believes that these measures will reduce the potential for exposures to aquatic organisms, it also believes that in specific geographical areas additional measures may be identified.
