REGULATORY and CERTIFICATION UPDATES
***MDA contacts Telone users***
The Michigan Department of Ag has mailed a safety notice about respitory protection
requirements to applicators who purchased fumigants containing the active ingredient
1,3 dichloropropene, known also as Telone or Tri-Form, within the last several
years. Similar letters were mailed to dealerships where such products were sold.
The safety notice reminds applicators of specific guidelines for respirators
and fit testing that are required on the Telone labels. The full text of the
safety notice is included at the end of this newsletter, in case you are contacted
by growers about the mailing.
*** Updates on Certification Manuals***
Corrections to the Spanish Pesticide Applicator Core, E-2195SP manual have been
made and it is now available through the MSU Bulletin Office. The numbering
of the answer key for the review questions was off in the final printed form.
The manual can also be downloaded in PDF format from our Website at: http://www.pested.msu.edu/BullSlideNews/bulletins/index.html
Also there has been an update to the Training Manual Order Form. The Category
5B manual, Microbial Pest Management E2435, went up in price after the last
reprint. There were no revisions made to the manual, so the old copies are still
good. The new manual order form should be dated "May 2004" at the top and can
be downloaded by clicking "Training Manual Order Form" from the above link.

*** CAST releases publication on managing pest resistance ***
The Council for Agricultural Science and Technology (CAST) released a Special
Publication entitled "Management of Pest Resistance: Strategies Using Crop Management,
Biotechnology, and Pesticides." Fifty-two presentations are collected in this
191-page proceedings from an April 2003 CAST-convened symposium on pest resistance
management (PRM). Major objectives of the meeting included identifying common
issues related to PRM across disciplines, considering ways to remove barriers
to effective preventive resistance management, describing research activities
in PRM, and disseminating this information to a wide audience. The complete
document, Special Publication 24, is available online only on the CAST website
at www.cast-science.org. [CAST News Release,
June 15, 2004]
***CCA treated wood***
EPA is releasing a document called 'Supplemental Guidance on Interpretation
of Revised Chromated Copper Arsenate (CCA) Wood Preservative Label'. This bulletin
is supposed to clarify the allowed and disallowed uses of CCA and CCA treated
wood. The bulletin also has a reference table with the American Wood Preservers
Association Commodity Standards for CCA, with examples of some of the uses that
are permitted or disallowed since the December 2003 voluntary cancellation.
The full text of the bulletin and the guidance chart are on-line at: www.epa.gov/pesticides/factsheets/chemicals/1file.htm.
***Bug Bomb Bulletin***

Q AND A
I received several questions in the last couple of weeks about mosquitoes.
- 'With all of the mosquitoes hatching, what is the latest on repellents?'
- 'My kids want to buy me a mosquito-attracting machine for Fathers Day - do
they really work?'
Answers: There are many good sources of information on mosquito repellents on
the internet. DEET labeling has changed a bit with regards to children, but
for the most part, DEET remains the most effective repellent on the market.
1) Center for Disease Control - Addresses the effectiveness of insect repellents,
including the interaction between repellents and sunscreen, gives specific info
on DEET, and provides CDCs own recommendations. http://www.cdc.gov/ncidod/dvbid/westnile/qa/insect_repellent.htm
2) EPA - Provides a detailed fact sheet on DEET discussing product registration,
safety, labeling, and use on kids. http://www.epa.gov/pesticides/factsheets/chemicals/deet.htm
3) National Pesticide Information Center - Provides a 4-page fact pesticide
fact sheet on DEET. Pesticides are listed in alphabetical order, so scroll down
the page to ?D?. http://npic.orst.edu/npicfact.htm
4) American College of Physicians - Web site provides a good technical article
for doctors that talks about mosquitoes, repellents and relief from insect bites.
The article compares the effectiveness of mosquito repellents such as DEET,
Avon Skin-So-Soft, Citronellas, Bite-Blocker, and Permethrin. It also talks
about mosquito machines like the mosquito magnet. http://www.annals.org/cgi/content/full/128/11/931
5) New England Journal of Medicine - Another articles aimed at physicians, comparing
types of repellents. This one specifically mentions DEET safety ("Deet
is far less toxic than many people believe")

PESTICIDES in the NEWS
*** Is there a mouse in your house?***
This news summary came from Don Baumgartner at the EPA Region 5 Office. While
pesticides used in the home have been cited as a cause or trigger for asthma,
a growing body of literature suggests that pests themselves also contribute
to the rising asthma rate in kids in the U.S. "Scientists at the National Institute
of Environmental Health Science have found that detectable levels of mouse allergen
exist in the majority (82%) of U.S. homes. NIEHS researchers analyzed dust samples
from 831 homes in the first National Survey of Lead and Allergens in Housing.
Allergen levels were studied and related to demographic factors and household
characteristics. The survey was conducted using established sampling techniques
to ensure that the surveyed homes were representative of U.S. homes. The homes
were sampled from seventy-five randomly selected areas across the entire country.
The 831 homes included all regions of the country, all housing types, and all
settings (urban, suburban, rural). Dust samples in the study were collected
from kitchen and living room floors, upholstered furniture, beds, and bedroom
floors. Kitchen floor concentrations exceeded 1.6 micrograms of allergens per
gram of dust in about one in five homes (22%). The amount of allergy-triggering
particles on the kitchen floor was high enough to be associated with allergies
and asthma. Residents of high-rise apartments and mobile homes were at greatest
risk, but allergens were present in all types of homes. The odds of having elevated
concentrations were increased when rodent or cockroach problems were reported.
Exposure to mouse allergen is a known cause of asthma in occupational settings.
Until now, exposure to these allergens had not previously been studied in residential
environments on a national scale. The report says that doctors should consider
these risk factors when treating allergy and asthma patients. The findings by
Cohn et al. appear in the June 2004 issue of the Journal of Allergy and Clinical
Immunology."
*** Ag Health Study presented at NCR Pesticide Education and Certification
Workshop***
Dr. Chuck Lynch of Iowa State University presented on update on the Agricultural
Health Study at the NCR Pesticide Education and Certification Workshop in St.
Louis, June 7-9. This study is primarily funded by the National Cancer Institute
(NCI). In the first 5 years of the study, 89,658 subjects (58,564 in Iowa and
31,094 in North Carolina) were enrolled. For the last several years the study
linked cohort members to mortality and cancer registry incidence databases in
both states. For the most part, private applicators had a lower incidence of
cancer than the general population. This was attributed to the fact that only
15% of the private applicators were smokers and to the healthier, more physical
life style of farmers. However, three cancers were more prevalent among private
applicators and/or their spouses: prostate, ovarian, and skin cancers. A higher
skin cancer risk is obvious for people who work in the sun. The numbers for
ovarian cancer were very low, so it was difficult for researchers to say whether
the difference was significant. The study examined 45 individual pesticides
and found that only methyl bromide showed a significant dose-response relationship
with prostate cancer risk. Preliminary findings in the study also suggest that
certain pesticides (chlorpyrifos, coumaphos, fonofos, phorate, permethrin, and
butylate) may interact with a particular form of one or more genes shared by
men with a family history of prostate cancer, making them susceptible to developing
the disease. The study is being expanded to commercial applicators. For further
information on the Agricultural Health Study, visit www.aghealth.org.

TEXT of the NOTICE SENT TO TELONE USERS in MICHIGAN June 18, 2004
***SAFETY NOTICE***
Fit -Testing, Training, and Medical Monitoring Needed When Using Respirators
for Particular Fumigants The Michigan Department of Agriculture (MDA) has been
reminded by the USEPA of requirements that must be met when respirators are
used with particular fumigants containing the active ingredient 1,3 dichloropropene.
The below respirator requirements have been in effect Federally since 1993.
Substantial health risks may occur from using these products unless the ?User
Safety Requirements? on the label are strictly observed. Applicators who apply
this pesticide must adhere to the following criteria when the label requires
use of a respirator:
1. Full face respirators must be worn.
2. Cartridges or canisters must be replaced daily or when odor or irritation
from this product becomes apparent, whichever is sooner.
3. Respirators must be fit-tested and fit-checked using a program that conforms
to Occupational Safety and Health Act?s (OSHA) requirements (described in 29CFR
Part 1910.134).
4. Respirator users must be trained using a program that conforms to OSHA?s
requirements (described in 29CFR Part 1910.134) (only for 1,3 dichloropropene
products).
5. Respirator users must be examined by a qualified medical practitioner to
ensure physical ability to safely wear the style of respirator to be worn (only
for 1,3 dichloropropene products).
During routine and misuse agricultural and Worker Protection Standard (WPS)
inspections this year and thereafter, MDA inspectors will be verifying compliance
with these label requirements. MDA encourages that dealers distribute this Safety
Notice to purchasers of the below products that must adhere to the required
respirator fit testing, training, and medical monitoring.
Michigan Registered Fumigants Containing 1,3 Dichloropropene:
Name = EPA Registration Number
Tri-Form 30 = 11220-21-8853
Tri-Form 35 = 11220-22-8853
Telone C-17 Soil Fungicide and Nematicide = 62719-12
Telone II Soil Fumigant* = 62719-32
Telone C-35 = 62719-302
Telone EC = 62719-321 In-Line = 62719-348
*May have slightly different respiratory requirements (see label).
PPE Exception Not Recommended with Enclosed Cabs
In the past, under the WPS certain pesticide labels have included an exception
for the use of a respirator if the application is made using an enclosed cab
that meets specified standards. Labeled exceptions to PPE in enclosed cabs are
permitted only if:
*the ventilation system of enclosed cab is properly functioning and maintained,
according to manufacturer?s written directions and;
* the manufacturer or a Government agency declares in writing that a particular
enclosed cab offers respiratory protection equivalent to or greater than the
specific labeled respirator (dust/mist or vapor/gas respirator).
All growers/applicators taking advantage of this respirator exception should
have on hand a written certification from ASAE or the manufacturer as proof
that the cab can be used in place of PPE, if inspected by MDA.
The WPS PPE exception also permits a long-sleeved shirt, long pants, shoes,
and socks for any labeled PPE in properly maintained enclosed cabs. In all situations
under the exception, applicators in enclosed cabs shall still have all labeled
PPE immediately available and stored in a chemically resistant container. This
labeled PPE must be worn if exiting the cab within the previously treated field.
Be advised that the American Society of Agricultural Engineers (ASAE) and most
other manufacturers no longer certify cabs to meet the required standards for
the exception because new studies have shown that enclosed cabs provide ineffective
respiratory protection whereas formerly they were believed to be protective.
Most manufacturers who had previously certified cabs as replacements for respirators
have now withdrawn their certification. Therefore, ASAE, EPA, and MDA believe
that the use of an enclosed cab in place of a full-face or dust/mist respirator
is no longer acceptable. Respirators should be worn even when an applicator/handler
is in an enclosed cab.
If you have further questions, please call Dr. Brian J. Hughes, Toxicologist,
at 517-241-3267 or Mr. Thomas Benner, Pesticide Enforcement Manager, at 517-373-9748.
