GROUNDWATER/PESTICIDE INFORMATION TRAINING SESSIONS ESTABLISHED FOR AGENTS AND
SPECIALISTS IN NEW YORK STATE
Five regional training sessions have been established throughout New York
State to provide pesticide/groundwater information to Cornell Cooperative
Extension staff involved with pesticide applicator training (PAT). A program
agenda has been sent to all the agricultural program leaders and field staff
on our newsletter mailing list. All meetings are at the appropriate extension
office and will begin at 8:30 a.m. and run until approximately 3:30 p.m.
Representatives from the New York State Department of Environmental
Conservation and the Environmental Protection Agency will be participating in
the program. Pesticide recertification credits will be offered.
At least one person from each Cornell Cooperative Extension Association
should plan to attend. Please contact our program (607) 255-1866 at least one

VINCLOZOLIN (RONILAN) SPECIFIC EXEMPTION GRANTED AND AMENDED
The Environmental Protection Agency (EPA) granted New York State a
specific exemption, FIFRA Section 18, on June 5, 1992 for the use of the
fungicide vinclozolin (Ronilan) on snap beans to control gray and white molds.
The initial exemption allowed for the application by ground equipment only.
Due to the wet weather conditions throughout most of July, EPA will now allow
Ronilan to be applied by aerial application. A complete copy of the EPA use
directions can be accessed from CENET (CHEM-NEWS) or obtained from PMEP.

NATIONAL PESTICIDE SURVEY
The US Environmental Protection Agency (EPA) recently completed Phase II
of its National Survey of Pesticides in Drinking Water Wells (NPS). In Phase
II, EPA analyzed the data to learn how pesticides and nitrate in wells are
related to groundwater sensitivity to contamination, fertilizer and pesticide
use, precipitation, farming practices, chemical characteristics of pesticides,
and the age, depth, construction and location of drinking water wells.
EPA found that detections were associated with such measures as data on
pesticide and nitrogen fertilizer sales, and agricultural activities. For
example, pesticide detections in rural wells were highly correlated with the
market value of crops grown nearby. In areas with fertilized pasture and
rangeland for beef cattle, pesticide detections were less likely. Nitrate
detections were related to the market value of livestock and to the amount of
fertilizer sold. Near urban areas and golf courses, there was a relation
between detections of DCPA (Dacthal) acid metabolites and the amount of DCPA
used.
In general, the EPA found that in areas with more rain or snow, wells
were less likely to contain detectable contaminants. Wells near lakes and
rivers were less likely to have pesticides or nitrates, but shallower wells,
older wells, and wells with low water temperature or pH were more likely to
have detections. More persistent pesticides were more likely to be detected.
A number of pesticide degradates also appeared in some wells.
Nitrate and DCPA acid metabolites appeared in wells most often. Overall,
about 10.4 million people in the US are served by community (CWS) or domestic
wells that contain DCPA acid metabolites, though no one is expected to be
exposed above the Lifetime Health Advisory Level (HAL) of 4000 parts/billion
(ppb). About 4.5 million people, including 66,000 infants, are served by
wells that exceed the maximum contaminant level (MCL) for nitrate (10 ppm).
EPA estimates that about 10 percent of CWS wells and 4 percent of rural
domestic wells contain detectable pesticides, but that no more than about 7
percent of CWS wells that contain pesticides exceed and MCL or health
advisory. No more than about 28 percent of the rural wells that contain
detectable pesticides are expected to exceed a health limit. Overall, an
estimated less than 1 percent (less than 80,000 public and private) of all US
drinking water wells exceed a health limit for one or more pesticides.

FDA, EPA AGREE ON PLANT BIOTECH JURISDICTIONS
Unveiling its plant biotechnology guidelines, FDA said it agrees with
EPA that substances that are pesticides are to be regulated by EPA, but that
FDA's authority "extends to any non-pesticide substance that may be
introduced into a new plant variety that is expected to become a component of
food."
"Any food safety questions beyond those associated with the pesticide,
such as those raised by unexpected or unintended compositional changes, are
under FDA's jurisdiction ...," the document said. The jurisdictional split was
specified as follows:
EPA: "(1) Substances that are intended to kill insects (e.g.,
Bacillus thuringiensis deltaendotoxin); (2) substances
intended to protect plants from viral, fungal, or bacterial
infection (e.g., cecropin); and (3)substances that are plant
regulators."
FDA: "(1) Substances intended to alter the nutritional
composition of the food (e.g., amino acids or carbohydrates);
(2) substances intended to enhance the plant's resistance to
chemical herbicides (e.g., bromoxynil, glyphosate, and
sulfonylurea); and (3) substances intended to alter the flavor
or the texture of the food."

BACTERIAL BREAKDOWN OF PARATHION, 2,4-D DESCRIBED
Researchers have successfully used the bacteria Pseudomonas cepacia and
Pseudomonas dimunita to break down parathion and 2,4-D and plan to test the
bacteria under field conditions.
The University of Idaho researchers, supported by USDA, found that
"pesticide mixing, loading and cleaning operations require detoxification and
disposal of empty containers, tank rinse waters, and spilled materials. A
single washing of the outer surface of ground spray rigs and aircraft can
produce 80 to 100 gallons of contaminated rinsate. The bacteria Pseudomonas
cepacia and Pseudomonas dimunita, which produce enzymes capable of breaking
down the pesticides parathion and 2,4-D, were entrapped in an alginate gel,
and freeze-dried, or immobilized on kaolinite clay and air-dried. The
bacteria survived for as long as three months in this form, and even after
extended storage they retained the ability to degrade their target compounds
in actual residues from used containers."

FEDERAL REGISTER NOTICES - PESTICIDES
Imazethapyr (Pursuit)
A tolerance has been established for the ammonium salt residues of
imazethapyr (Pursuit) at 0.1 p.p.m. in or on corn grain, fodder and forage.
However, the tolerance for residues of the herbicide is due to expire May 27,
1994. The tolerance had been petitioned by American Cyanamid.
Fosetyl-Al (Aliette)
EPA has broadened the tolerance of 0.l p.p.m. in or on fresh ginseng root
for residues of aluminum tris (Aliette) to permit use in all states. The
tolerance had been limited to use in Wisconsin. The expansion of the
tolerance for the fungicide was proposed by the agency, based on a petition
submitted by Interregional Research Project No. 4.
Carbon disulfide
Temporary tolerances, granted to Unocal Agriproducts for residues of the
nematicide carbon disulfide, were renewed until Dec. 15, 1993. The tolerances
are 0.1 p.p.m. in or on almonds, almond hulls, apricots, grapes, grapefruit,
lemons, oranges, peaches, plums (fresh prunes) and tomatoes. The residues
result from soil applications of sodium tetrathiocarbonate.
Fenoxaprop-ethyl (Acclaim)
A temporary tolerance granted Hoechst Celanese for fenoxaprop-ethyl was
extended to April 10, 1993. The tolerance is 0.05 p.p.m. in or on barley
grain. The herbicide is (+)-ethyl 2-[4-[(6-chloro-2-benzoxazolyl)oxy]phenoxy]
propanoate and its metabolites 2-[4-[(6-chloro-2-benzoxazolyl)oxy]phenoxy]

SECTION 18 APPLICANTS TOLD TO FOLLOW NEW GUIDANCE
Section l8 emergency exemption applications for the 1993 use season will
be evaluated on the basis of guidance and instruction documents distributed by
EPA.
Under FIFRA, a Section 18 exemption may be granted to allow a
nonregistered use in emergency situations.
In defining an emergency, the guidance spells out three conditions that
must be met:
"(1) no effective registered pesticides are available,
(2) no feasible alternative control practices are available,
and (3) the situation involves the introduction of a new
pest or will present significant risks to human health or
the environment or will cause significant economic loss."
The guidance document, developed over the past three years by a Section
18 workgroup, is intended "to clarify the agency's position on certain issues
that have become controversial or problematic," Lindsay said. The instruction
document is a step-by-step guide for preparing Section 18 applications.
After Oct. 1, agency staff will work with applicants to rectify minor
deficiencies in their submittals, said Lindsay, but "major deficiencies in an
emergency exemption application will result in immediate rejection." That
warning in Lindsay's memo appeared in underlined, boldface type.
She also called attention to a number of other requirements that apply
under the guidance.
Applications based on lack of efficacy of registered alternatives, she
said, must include efficacy data comparing the pesticide proposed for use to
currently registered pesticides or alternative practices.
"If valid efficacy testing data are not available for any of the
alternative control measures, other scientific information must be provided to
support claims that a particular control measure is inadequate or
impractical," Lindsay explained.
"Applications based on the potential for significant economic loss," she
said, "must be supported by yield and/or quality data which compare the
proposed pesticide to the alternatives to substantiate yield loss claims, and
five years of yield, price received and variable cost of production (or crop
budget) data. In addition, estimated gross and net revenues for the site
without the use of the proposed pesticide must be provided which reflect the
mean expected yield loss if growers use the next best practical means of
control.

INTENT TO SUSPEND NOTICES PUBLISHED
In the June 26 Federal Register, EPA published two notices of intent to
suspend for lack of data submissions under requirements of Section 3(c)(B).
Products and registrants were listed as:
Dodine 65-W Fungicide of Aceto Chemical; Green Turf Weeder 60
Plus and Green Turf Weeder 75 Plus of Wilbro, Inc.;
Warfarin/Warfarin Salt of Hobby's Rat & Mouse Bait, Inc.
Pesticide & Toxic Chemical News. Vol. 20, No. 36. July 8, 1992
SULFUR REREGISTRATION ELIGIBILITY DOCUMENT AVAILABLE
The EPA announced the availability of the amended reregistration
eligibility document (RED) for sulfur and concludes the comment period. The
amendment exempts certain sulfur products labeled only for home and garden use
from the 14-hour reentry labeling requirement. However, on labels which list
both agricultural and home and garden uses, the directions for use for home
and garden applications must be listed separately from the directions for use
on agricultural applications so that the reentry statement will not apply to
the home and garden uses.
