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.

(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.

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.

(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.

(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).

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 .

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,

(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.

(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

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,

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.

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

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)

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.

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

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.

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.

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.

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.
