(1)  AZINPHOS METHYL 5/10/99
If you use azinphos methyl, get ready to make comments on its risk assessment.  On May 19,  EPA will sponsor a technical briefing for this insecticide.  The briefing will
provide an opportunity for the public to learn about the data, information, and methods
that the Agency used to develop and revise the risk assessment.  This will be the first
such meeting to present to the public a revised risk assessment for an organophosphate pesticide.  Representatives from USDA will provide ideas on possible risk management.  Following the briefing, EPA will release the revised risk assessment for public availability.  The public will be encouraged to submit risk management ideas and proposals.  Comments will be taken until July 19.  Contact Susan Whitney (swhitney@udel.edu; 302-831-8886; fax: 302-831-3651) if you would like a copy of the risk assessment.  Additional information can be found at: http://www.epa.gov/pesticides/OP/status.htm.

(2)  AZINPHOS-METHYL RISK ASSESSMENT COMMENTS DUE 7/16 (26 MAY 1999)
On May 19, EPA/USDA held the azinphos-methyl risk assessment technical
briefing.  A summary of the risk assessment can be found at:
http://www.epa.gov/pesticides/op/azinphos/azmsum.htm
The complete document is at: http://www.epa.gov/pesticides/op/azm.htm
(select "Revised Health Effects Assessment").  Apples, peaches and pears
are major contributors to the risk estimates.  Acute risks for infants
and children are of concern; however, chronic risk is not a concern.
Worker risk is very high even with maximum PPE/engineering controls.

Growers have until July 19, 1999 to submit comments to EPA.  Such
comments could address ideas about how to manage dietary, occupational,
or ecological risks on specific azinphos-methyl use sites or crops in
Delaware. To address dietary risk, for example, commentors may choose to
discuss the feasibility of lower application rates, increasing the time
interval between application and harvest, modifications in use, or
suggest alternative measures to reduce residues contributing to dietary
exposure. For occupational risks, commentors may suggest personal
protective equipment or technologies to reduce exposure to workers and
pesticide handlers. EPA also welcomes suggestions for reducing
environmental exposure.

You must include the docket control number OPP-34131C with your
comments.  Mail comments to: Public Information and Records Integrity
Branch, Information Resources and Services Division (7502C), Office of
Pesticide Programs, Environmental Protection Agency, 401 M St., SW.,
Washington, DC 20460.  Or send an e-mail to: opp-docket@epa.gov.
Contact Susan Whitney (swhitney@udel.edu; 831-8886) if you need help
getting these documents or making comment.

(3)  EPA CANCELS/REDUCES USES OF METHYL PARATHION AND AZINPHOS METHYL (04 AUG 1999)
     EPA announced on Monday August 2 that they have canceled use of methyl parathion on apples, peaches, pears, grapes, nectarines, cherries, plums, carrots,
certain peas, certain beans, and tomatoes, among other fruits and vegetables. EPA has also reduced the application rate of azinphos methyl and will require practices that will result in significant reductions in allowable residues on apples, pears and peaches.

     EPA said, "Our actions today will protect children from the adverse effects of
exposure to pesticides commonly used on foods.  The Agency also is on schedule to
meet all deadlines for ensuring safer pesticide use under the new Food Quality
Protection Act."  They state that their actions are being taken after an extensive
scientific review of the risks posed by these chemicals.  EPA says that they have
worked closely with USDA and the agricultural community to ensure that this decisions
will not disrupt growing and marketing plans of farmers.

    EPA also says, "The reductions EPA is making will address the unique risks children
face when exposed to pesticides.  For example, it is known that some pesticides pose a greater risk to infants and children because their bodies and internal organs are still
developing, which makes them much more susceptible to the effects of pesticides.
Children also ingest greater quantities of food and drink relative to their body weight, as
compared to adults, which increases their exposure to pesticides."

     A schedule outlining the review of the organophosphates, and a progress report
on FQPA is available at:  www.epa.gov/pesticides.

(4)  EPA REQUESTS RISK MANAGEMENT COMMENTS FOR FOUR OP’s BY NOVEMBER 1
EPA would like risk management and mitigation ideas, as well as, recommendations for transition related to ethoprop, fenamiphos, terbufos, and phorate.  Such comments and proposals could address ideas about how to manage dietary, occupational, or ecological risks on specific use sites or crops across the United States or in a particular geographic region of the country. To address dietary risk, for example, commentors may discuss the feasibility of lower application rates, increasing pre-harvest intervals, modifications in use, or suggest alternative measures to reduce residues contributing to dietary exposure. For occupational risks, commentors may suggest PPE or technologies to reduce exposure to workers and pesticide handlers.  All comments and proposals must be received by EPA on or before November 1, 1999.

To ensure proper receipt of your comments, you must identify docket control numbers OPP-34144C for ethoprop, OPP-34134B for fenamiphos, OPP-34137B for phorate, and OPP-34139C for terbufos in the subject line on the first page of your response.  Mail comments to: Public Information and Records Integrity Branch, Information Resources and Services Division (7502C), Office of Pesticide Programs, Environmental Protection Agency, 401 M St., SW., Washington, DC 20460.  Or you may e-mail comments to: opp-docket@epa.gov

5)  METHYL PARATHION RISK MANAGEMENT DECISION 
EPA's risk assessment showed that methyl parathion could not meet the FQPA safety standard as the pesticide is currently registered. The acute dietary risk to children age one to six exceeded the reference dose (amount that can be consumed safely over a 70-year lifetime) by 880%. To mitigate the high dietary risk to children, EPA accepted voluntary cancellation of those crops that contribute most to the children's' diet. Existing stocks of methyl parathion products with canceled crop uses may be applied until December 31, 1999. The use cancellations will become effective early next year. Registrants of methyl parathion will amend their labels to allow reformulation only to those uses being maintained. Registrants may repackage or re-label their products to reflect only the maintained uses. Application of methyl parathion for the canceled uses will be prohibited for the 2000 growing season. These canceled uses represent 90% of the dietary risk to children. Removing these crop uses brings the estimated dietary risk down to 78% of the reference dose, making the risk from food acceptable for children and all others in the U.S. population.

Canceled Children's Food Uses: All fruit (apples, peaches, pears, grapes, nectarines, cherries, and plums), carrots, succulent peas, succulent beans, and tomatoes. 

Other Canceled Food Uses: Artichokes, broccoli, Brussels sprouts, cauliflower, celery, collards, kale, kohlrabi, lettuce, mustard greens, rutabagas, spinach, and turnips. 

Canceled Non-Food Uses: Ornamentals, grasses grown for seed, mosquito use, and nursery stock. 

Uses Remaining: Alfalfa, almonds, barley, cabbage, corn, cotton, dried beans, dried peas, grass, hops, lentils, oats, onions, pecans, rape seed (canal), rice, rye, soybeans, sugar beets, sunflower, sweet potato, walnuts, wheat, and white potatoes. 

Additional Protection for Workers:  EPA states that PPE are not sufficient to reduce the risks to workers to acceptable levels. By canceling all fruits and many vegetables, workers will be better protected because many of these crops are hand-harvested. By canceling all non-agricultural uses of methyl parathion, risks to certain other workers will also be eliminated.  To increase worker protection for the 2000 growing season, the registrant has increased reentry intervals from two days to four-to-five days. To increase the safety of uses that will continue, for the 2001 growing season, the registrant has agreed to require enclosed cabs and cockpits as well as closed mixing and loading systems. They will also generate exposure studies to resolve outstanding post-application issues. 

RETURN TO TOP

(6)  AZINPHOS METHYL RISK MANAGEMENT DECISION
EPA has accepted voluntary measures to reduce both dietary and worker risks from azinphos-methyl. The risk mitigation measures for azinphos-methyl will be in place for the 2000 growing season.  As it is currently registered, azinphos-methyl poses an unacceptable dietary risk to children ages one to six years. It also poses risks of concern to agricultural workers. 

EPA's risk assessment showed that azinphos-methyl could not meet the safety standard of FQPA as the pesticide is currently registered. The acute dietary risk from food alone is unacceptable for nursing infants and children age one to six. In addition, the limited surface and ground water data available indicate that drinking water will further contribute to acute dietary risk. The risk from occupational exposure to azinphos-methyl is greatest for workers reentering treated fields and orchards, although risk to mixers, loaders and applicators also is of concern. 

Summary of Risk Reduction Measures:

Reduce Use on Apples, Pears, Quinces and Crabapples, establish a maximum seasonal use rate and increase the time between application and harvest. Lower the tolerance for pome fruit from 2.0 ppm to 1.5 ppm now and to 1.0 ppm in 2001. (The registrant must demonstrate with comparative residue data that these measures achieve the expected reductions in exposure or additional actions will be taken.) 

Cancel Cotton East of the Mississippi River and All Sugarcane Use: These uses appear to be a major factor contributing to drinking water exposure.

Cancel Ornamental, Christmas Tree, Forest Tree, and Shade Tree Uses: These cancellations will reduce exposure to affected ecosystems. 

Cap Production of Product Available in the U.S.: The cap is intended to prevent use of other pesticides shifting to azinphos-methyl as a result of other actions, such as the cancellation of many uses of methyl parathion. 

Reduce Worker Exposure: Increase REI’s.  All application with hand-held equipment will be prohibited. Closed mixing/loading systems and enclosed cabs will be required, as will additional worker exposure testing. 

(7)  THE REGULATORY OPENNESS AND FAIRNESS ACT OF 1999 COULD TEMPER FQPA
Both the Senate and the House have introduced versions of the Regulatory Openness and Fairness Act of 1999.  If passed, this law would require EPA to identify the assumptions or defaults used in making tolerance decisions and use actual data and scientifically sound information when modifying or revoking tolerances.  EPA would be required to monitor the competitive strength of major US agricultural commodity sectors in the international marketplace, with emphasis on the impact of FQPA regulatory decisions.

RETURN TO TOP

(8)  NEXT PESTICIDES TO GO THROUGH RISK ASSESSMENT:  ETHOPROP, FENAMIPHOS, TERBUFOS, AND PHORATE
On September 2, 1999, the revised risk assessments for four OP’s will be released by EPA:  ethoprop, fenamiphos, terbufos, and phorate.  At this time growers will be asked to suggest risk mitigation measures to EPA.  Such measures could help keep commodities on these pesticide labels.  Be prepared to make suggestions when the time comes.  

(9)  RISK MANAGEMENT PUBLIC PARTICIPATION PERIOD BEGINS FOR CHLORETHOXYFOS (FORTRESS)
EPA will be considering risk management measures for Fortress in corn until October 18, 1999.  Fortress will be included in the cumulative risk assessment for OP’s, as required by FQPA.  EPA is willing to meet with stakeholder groups and intends to contact them directly.  Growers may submit risk management and mitigation ideas, as well as recommendations and proposals for transition related to Fortress.  For more information, contact Karen Angulo, Special Review and Reregistration Division, at 703-308-8004 (email at angulo.karen@epa.gov).

RETURN TO TOP

(10)  WORKER RISK MITIGATION FOR ORGANOPHOSPHATE PESTICIDES
The risk assessments that EPA has completed so far show that measures beyond
those specified by the Worker Protection Standard are needed to adequately protect workers and handlers of OP’s.  EPA believes that an across-the-board increase in risk mitigation measures is needed to protect occupational users of OP’s. 

Some examples of types of engineering controls which might be considered include:  Closed systems for mixing and loading, water-soluble packaging, mechanical closed mixing system, mechanical transfer system, enclosed cabs for application and flagging, or enclosed cockpits for aerial application. Application modifications such as decreased application rates may be required.

Where closed application systems are not feasible, for example, some greenhouse applications and some orchard applications under dense canopy, EPA intends to seek maximum feasible PPE which may include respirators, as well as modifications to use patterns. 

It is likely that exposures from certain application methods such as hand-held equipment, backpack sprayers, etc., can not be mitigated adequately by PPE or other  measures.  Also, the use of human flaggers will be strongly discouraged unless these  workers can be in enclosed cabs.  For harvesters and other worker reentering treated fields, Restricted Entry Intervals will be extended to provide adequate protection. 

In situations where risks continue to exceed benefits even after consideration of maximum PPE, engineering controls, and modifications to the use pattern, EPA will consider cancellation of the use. EPA’s goal is to have substantial worker risk mitigation in place for all the OP pesticides by December 31, 2000.

(11)  CHLORPYRIFOS RISK ASSESSMENT 
Chlorpyrifos, has begun the first phase of the six-phase process for development of a risk assessment and risk mitigation plans. Phase 3 is a 60-day public comment period.  When this begins, EPA and USDA will alert the land-grant universities and affected commodity groups, and also provide a summary and list of sections in the assessment where data and assumptions should be evaluated by the agricultural community. 

During Phase 4, EPA revises the assessment. The USDA and land-grant universities  contribute again by reviewing the revised assessment. The revised assessment, which EPA may present at a technical briefing, is then publicly posted. This begins Phase 5, in which risk mitigation suggestions are sought through a 60-day comment period. In Phase 6, another 60-day period, a completed risk mitigation plan is produced.  

Any one may look at the risk assessment during the public comment periods by checking the EPA web site at  http://www.epa.gov/oppsrrd1/op/status.htm . An explanation of how to comment may be found at http://www.epa.gov/oppsrrd1/op/involve.htm .

(12)  EPA REVIEW SCHEDULE FOR ALUMINUM AND MAGNESIUM PHOSPHIDE
EPA plans to issue a revised set of proposed risk mitigation measures this month for Aluminum and Magnesium Phosphide.  Then they will hold stakeholder meetings in October and November and issue final risk mitigation measures needed for reregistration, in late 1999 or early ‘00.  EPA invites all interested individuals and groups to participate in the ongoing stakeholder process.  For information, contact Mark Hartman in the Office of Pesticide Programs, telephone 703-308-0734, e:mail Hartman.Mark@epa.gov.

(13)  NEW WEB SITE ON PESTICIDE SAFETY PROGRAMS
EPA has created a new web site, http://www.epa.gov/pesticides/safety , to provide farm workers, certified applicators, and health care providers with information on the Agency's pesticide safety programs.  This web site,  which can be accessed in English and Spanish, provides specific information on applicator certification and training requirements and EPA's Worker Protection Standard, including pesticide safety training, notification of pesticide applications, use of personal protective equipment and emergency medical assistance.  The site also provides information on the Pesticides and National Strategies for Health Care Providers, an EPA-led initiative aimed at helping health care providers become trained in diagnosing and preventing pesticide related illnesses.

(15) EPA TURNS TOWARD TOLERANCE REASSESSMENT OF NON-OPS (9/99)
Pesticides other than OP's are coming up for reregistration.  Real world
data are essential for regulatory decision-making.  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.

EPA's advice to growers:  tell registrants about your critical uses;
don't assume that registrants already know.

(16)  DICROTOPHOS AND TRICHLORFON
        Preliminary risk assessments for the OP's dicrotophos and trichlorfon have been prepared.  Public comment will be taken until January 10, 2000.  EPA is interested in obtaining additional data to further refine the risk assessment, such as percent crop treated information or residue data from food processing studies.  Comments addressing EPA's risk assessment methods and assumptions as applied to dicrotophos and trichlorfon also would be useful.  Comments must be identified by docket control number OPP-34206 for dicrotophos and OPP-34207 for trichlorfon. The preliminary risk assessments are available on EPA's home page: http://www.epa.gov/pesticides/op/dicrotophos.htm

(17)  OXYDEMETON METHYL, DIMETHOATE, ETHYL PARATHION AND METHIDATHION.
        OP 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.

(18)  IR-4 RESEARCHES METHYL BROMIDE ALTERNATIVES FOR STRAWBERRIES AND TOMATOES 
        IR-4, the USDA-supported program that develops data to support pest
control registrations for minor crops, is working to find minor crop
solutions to the phasing out of methyl bromide. Methyl bromide is a
highly effective soil fumigant used extensively to control soilborne
diseases, nematodes, soil insects, and weeds. However, due to its
ozone-depleting capabilities, methyl bromide is scheduled for complete
phase-out by 2005. About 80% of preplant methyl bromide uses are for
strawberries and tomatoes. IR-4 is working to develop safe products and
new technologies that will fill the gap created when methyl bromide is
no longer available for use on these crops. Field trial programs to test
alternative products will begin in fall 1999 for strawberries, and
spring 2000 for tomatoes. For more information contact Dr. Jack Norton
at IR-4 Headquarters, 732- 932-9575x612, norton@aesop.rutgers.edu.

(19)  REVOKED TOLERANCES ON LIVESTOCK FEED THAT ARE NO LONGER NEEDED
The USEPA has revoked the tolerances for pesticide residues in or on livestock feed commodities that have been deleted from the list of significant livestock feed commodities.  They no longer require data on or set individual tolerance levels for minor, non-significant livestock commodities.  They consider a livestock feed commodity to be significant if it has the potential to contribute to the human diet through
human consumption of livestock commodities.  It is not the USEPA's intention that these revocations should have the effect of limiting use of pesticides or rendering the affected commodities adulterated due to the absence of a tolerance.  They consider these revoked tolerances for pesticide residues to be covered by the tolerances for each pesticide on the principal commodities of a crop.  This rule was effective on January 16, 1998.

(20)  VINCLOZOLIN (RONILAN, ORNALIN) REVOCATIONS 
       The USEPA has revoked the tolerances for residues of the fungicide vinclozolin in or on the commodities of GRAPES (other than wine grapes), PLUMS, PRUNES, and TOMATOES.  This action was effective as of February 13, 1998.  The USEPA is revoking these tolerances because the uses associated with them have recently been voluntarily deleted from vinclozolin's registration and were removed from BASF Corporation (the basic producer) labels in 1991.  Written objections or requests for a hearing must be received by 4/14/98. 

RETURN TO TOP

(21)  PROPOSED REVOCATION OF TOLERANCES AND EXEMPTIONS FOR PESTICIDES NO LONGER REGISTERED FOR USE ON SPECIFIC FOOD CROPS
       The USEPA has issued two Federal Register notices that propose to revoke 871 tolerances and exemptions from the requirement of a tolerance for pesticides on food products.  This is a final opportunity for anyone who wants to continue to support any of  these tolerances (the associated uses of which are now canceled) to come forward and provide the appropriate data.  Listed here are the specific crop-pesticide uses that were associated with these proposed tolerance revocations.  It is the USEPA's general practice to propose revocation of those tolerances and exemptions for residues of pesticide chemicals for which there are no active registrations.

       According to USEPA records, there are no active registrations for the specific crop-pesticide combinations listed here.  Also, they believe that all existing stocks of pesticide products labeled for these uses were exhausted more that one year ago, giving ample time for any treated fresh produce to clear trade channels.

       We urge you to check this list for your specific commodity to verify that there is no active use of the pesticides listed here for your commodity. This includes any use on imported commodity products.  Please notify the USEPA if you wish to retain any of these tolerances. They will not revoke any tolerance or exemption proposed for  revocation if any person will commit to support its retention, and if retention of the tolerance will meet the tolerance standard established under the Food Quality Protection Act (FQPA).  Delaware Crop-pesticide list of canceled uses associated with the tolerances proposed for revocation by the USEPA on 1/21/98 and 2/5/98

(22)  FQPA LIST (3/26/98)
As you know, the Food Quality Protection Act will target OP's for the
first round of tolerance reassessments.  Last week EPA issued a list
of OP's/commodities that will be studied first.  They are asking states to
contribute any data that we have on OP use. In the next issue of Pesticide
Briefs, we will have a form for growers to list critical uses of these
chemicals on Delaware's crops.  If you get questions from growers, please
emphasize the importance of collecting this data.

OP's to be targeted:
Acephate
Azinphos-Methyl
Chlorothoxyaphas
Chlorpyrifos
Diazinon
Dicrotophos
Dimethoate
Disulfoton
Terbofos
Ethion
Ethoprop
Ethyl Parathion
Fenamiphos
Fonofos
Malathion
Methidathion
Methyl Parathion
Trichlorfon
Naled
Oxydemeton Methyl
Phorate
Phosmet
Profenofos
Sulprofos

List of priority Crops for Information Development.  EPA wants
data on real life uses of OP's on these commodities.  If they don't get
this data they will resort to "worst case" scenarios based on maximum
label recommendations.  These commodities have been chosen because of
their use in the diets of infants and children:

apples
oranges
peaches
soybeans
pears
carrots
rice
beef (boneless/lean)
coconut oil
corn(popcorn, sweet corn, field corn)
potatoes
bananas
wheat
sugarcane
beans (green/succulent)
oats
eggs
tomatoes
peas (garden)
chicken

(23)  GORE SENDS MEMORANDUM TO EPA ON FQPA (9 APR 1998)
The White House just released a memo that VP Gore sent to EPA
Administrator Browner and USDA Secretary Glickman outlining principles
that Gore wants followed as EPA carries out the Food Quality Protection
Act.  Gore said in his memo that he understood that the EPA did not intend to
cancel any significant pesticide uses this growing season, adding, "If
this should change based on new information, there should be immediate
consultation with USDA and the affected constituencies."

Gore outlined other steps for a "reasonable transition for agriculture,"
including providing time and technical help to change to new pest
management strategies and speeding EPA approval of alternative products.
He said the EPA and USDA should review their budgets and within 14 days
find additional resources to speed product approvals and expand
alternative pest management strategies.

Also within 14 days, Gore said the two agencies should consult to set up a
system to get a variety of outside views including various interest
groups, state and local agencies, Congress and the public.  The memo also said, "President Clinton and I will not waver in our commitment to protecting children's health. Nor are we willing to sacrifice the strength and competitiveness of our agricultural communities."  Sounds like a sensible approach.  Now let's see if it works.

(25)  US METHYL BROMIDE PHASEOUT DELAYED 4 YRS (29 OCT 1998)
This is from the EPA website on changes in the Methyl Bromide phaseout at:
http://www.epa.gov/ozone/mbr/harmoniz.html

Changes to the Methyl Bromide Phase Out in the United States:
The methyl bromide phase out in the United States has changed!! The U.S. will no longer be phasing it out in 2001!  Due to recent legislative actions by the U.S.  Congress, the methyl bromide phase out in the U.S. has been changed to the following:

Methyl bromide production and importation will be reduced from 1991 levels as follows:

                 25% reduction in 1999
                 50% reduction in 2001
                 70% reduction in 2003
                 100% reduction in 2005
                 Preshipment and quarantine uses exempt
                 Critical agricultural uses allocated after 2005

(26)  TOLERANCES EPA PLANS TO REVOKE  (4 NOV 1998).
EPA issued two final rules on 10/26/98 that announced the revocation of
tolerances for residues of certain pesticides associated with canceled
food uses.  About 700 tolerances are being revoked which supported uses
that were once registered on more than 440 site-pesticide combinations.
They are listed below.  This final rule becomes effective on 1/25/99.

The reasons for the withdrawal of some proposed tolerance revocations are
specifically listed in EPA's final rules.  They include import
considerations, planned registration of associated uses, existence of
stocks of canceled products, existence of residues in available food
commodities, etc.  Many of these tolerances will be dealt with by EPA in
future reassessment and reregistration activities.

Please check the attached list.  If you find a site-pesticide combination
which is apparently threatened by a planned revocation of a tolerance and
you feel it is still necessary, you can file an objection or request a
hearing by 12/28/98 and possibly still stop a planned revocation.
However, before you do this, we recommend you first consult the EPA
contact, Dr. Joseph Nevola.  EPA will not revoke any tolerance if any
person demonstrates a need for the tolerance to cover residues in or on
imported commodities or domestic commodities legally treated, and if
retention of the tolerance will meet the tolerance standard established
under the Food Quality Protection Act (FQPA).

-------------------------------------
The following site-pesticide combinations are the uses associated with
the revoked tolerances published by EPA in the Federal Register on
10/26/98 to be effective on 1/25/99.  Most of these uses are canceled.
Uses based on the first list (63 FR 57062) of two lists published on that
date have an asterisk following the chemical name.  This list is not an
official interpretation of EPA's rulemaking.  It attempts to determine
the possible impact of tolerance revocations on pesticide use.  If you
find a use in this list that you would like to defend, we recommend that
you consult the EPA contact above, Dr. Joseph Nevola, to obtain an
official determination that your use will be impacted by the tolerance
revocations before you file a written objection or request a hearing.

(27)  CHANGES TO METHYL PARATHION (14 JAN 1997)
December 30th, EPA and Cheminova signed an agreement concerning methyl parathion.  It will become effective on or before Jan. 15.  This agreement is in response to misuse of methyl parathion in homes in other states.  This pesticide is registered     only for use in crops -- not structures  The agreement includes the following provisions:

     -  Total recall of all (unopened) methyl parathion EC formulations down to the end-user level.

      -  Addition of stenching agent to all MP EC formulations (eau de locker room -- can't use that in somebody's living room!).

     -  Packaging of all MP EC products in returnable/refillable containers which will have a barcode. Tracking by retailers of purchaser name will be mandatory and reported back to Cheminova and the information can be obtained by EPA.

     -Cheminova will lead an education program which will include: 
          -Product stewardship campaign
          -Develop training and outreach targeted to dealers, distributors, certified applicators, grower groups through its participation in the Best Management Practices Task Force.
          -Develop and help distribute a Public Service announcement which deals with indoor misuse of methyl parathion and other pesticides.

          As part of the agreement, Cheminova will cancel its existing registrations (and the other registrants will do so as well) and apply for me-too registrations with the above as part of the terms and conditions of registration, although the education program section will apply to Cheminova only.

          Need more info on this or another pesticide issue??  I'm back from "Down Under" now and ready to get you information you need to pass on to your growers.  Let me know!  Don't forget to put /27 on your calendar to learn about the Food Quality Protection Act.

(28)  INDOOR USE OF CHLORPYRIFOS -- LABEL CHANGES! (1/23/97)
These changes will appear soon on indoor-use labels -- I'll let you know when to expect them.  These changes may have implications for ag uses.
  1.      Withdraw chlorpyrifos from the:
     *    indoor broadcast flea control market.
     *    indoor total release fogger market.
     *    paint additive market.
     *    direct application pet care product market (shampoos,
       dips, sprays).

  2.      Take a number of steps to increase protections for high volume
  household uses (e.g., crack and crevice use) which should include:
  *     products are marketed to consumers in ready-to-use (rather
        than concentrated) form;
  *     labls prohibit use in inappropriate areas (e.g., drapes,
        furniture, toys);
  *     PCO's must clean spills and misapplications;
  *     applicators are properly trained and supervised;
  *     and restrictions are in place to protect families and pets during
        and immediately after applications.

  3.      Revise chlorpyrifos labels to include appropriate re-treatment
  intervals.  This will prevent buildup in the home.

  4.      Make label changes as soon as possible for safer termiticide and
  pet care products.

  5.      Accelerate education and training for PCO's on these measures
  to reduce risk and exposure, label improvements.

  6.      Undertake epidemiological research and establish a Blue Ribbon
  Panel to provide scientific direction for study design for chlorpyrifos.

  7.     Continue the Poison Control Center Stewardship Project for
  chlorpyrifos to monitor incident reporting related to chlorpyrifos.

  The following is taken from a letter from Lynn Goldman (EPA) to
  DowElanco dated 1/14/96:

  "... EPA has recently completed a review of chlorpyrifos that describes
  potential risks associated with the household and termiticide uses.
  Based on this review, EPA believes that it is important to strengthen
  the protections via changes in the registrations and labeling for this
  pesticide to prevent potentially harmful exposures.... reported health
  concerns about chlorpyrifos involve illnesses that are common to
  organophosphates, most notably, vomiting, diarrhea and nervous
  system disorders from acute exposure and possibility of chronic
  neurological disease from long-term exposures.  As chlorpyrifos is
  used in many household products, the EPA has identified certain
  immediate risk mitigation measures that we believe are critical to
  reduce exposures, increase right-to-know, and expand our knowledge
  about chlorpyrifos...."

  "...  Although the focus of the EPA immediate concern is chlorpyrifos,
  the Agency will seek similar measures for other indoor/household and
  termiticide products during the reregistration process. The Agency
  believes these risk mitigation measures for chlorpyrifos could serve as
  a model for the future reregistration of other indoor/household and
  termiticide products of concern..."

  Let me know if you get questions on this issue.  Feedback from
  extension agents and specialists is the way I decide where to
  concentrate educational efforts.  I have more info on this issue and will
  certainly be flooded with info in the next few days.  If you need help,
  let me know.

(29)  PESTICIDES AND WATER QUALITY: NEWS RELEASE (12 AUG 1997)
This morning (8/12) the Environmental Working Group plans to release a
report on triazines in drinking water in Ohio, Illinois and Missouri as a
follow-up to "Tap Water Blues ('94)" and "Weed Killer by the Glass ('95)."
This new report will be called: "Tough to Swallow: How Pesticide Companies
Profit from Poisoning America's Tap Water."

The report alleges "widespread, long term herbicide contamination of
Midwestern tap water," and that the 1996 Food Quality Protection Act
"closed a gaping loophole in Federal pesticide laws" by requiring that
pesticide food tolerances take into account, "for the first time"
exposures via drinking water.

The report alleges that "commonly used weed killers contaminate tap water
of 374 Midwestern towns; 144 in Ohio; 97, Illinois; 59 in Missouri; and 74
in nine other states." Thus, the report charges, "over ten million
Americans...are exposed to cancer causing weed killers in their tap
water."

The report's executive summary specifically names atrazine, simazine,
alachlor, and acetachlor; however, additional herbicides are treated in
the full report.

EWG recommends: (1) an immediate ban on all triazine herbicides; (2) an
announced EPA policy to phase out all pesticides that contaminate tap
water supplies; (3) adoption by the farming community of a goal of
controlling weeds without contaminating drinking water; (4) EPA must
"scrupulously" implement the Food Quality Protection Act, "with explicit
consideration of the higher exposure...and vulnerability of infants."

I have lots of electronic info on this report.  Let me know if you want to
look at it.  Also let me know if you get questions/ comments on this
report.
