New Tolerance
(PPs) 5E6965, 5E6966, 5E6967.
Interregional Project Number 4, 681
Highway 1 South, North Brunswick, NJ
08902–3390, proposes to establish
tolerances for residues of the insecticide
diflubenzuron, (N-[[(4–
chlorophenyl)amino]carbonyl]–2,6–
difluorobenzamide) and metabolites
convertible to p-chloroaniline expressed
as diflubenzuron in or on the following
food commodities:
1. (PP) 5E6965 proposes to establish
tolerances for barley, grain; oat, grain;
and wheat, grain at 0.06 parts per
million (ppm); barley, forage; oat,
forage; and wheat, forage at 5.0 ppm;
barley, hay; oat, hay; and wheat, hay at
2.0 ppm; barley, straw; oat, straw; and
wheat, straw at 2.0 ppm; barley,
aspirated barley fractions; oat, aspirated
oat fractions, and wheat, aspirated
wheat fractions at 3.0 ppm; and
pummelo at 0.5 ppm.

2. (PP) 5E6966 proposes to establish
tolerances for brassica, leafy greens
subgroup 5B; turnip at 8.0 ppm;
eggplant at 1.0 ppm; and okra at 1.0
ppm.
3. (PP) 5E6967 proposes to establish a
tolerance for peanut at 0.2 ppm.
A practical analytical method for
detecting and quantifying levels of
diflubenzuron in or on food with a limit
of detection that allows monitoring of
the residue at or above the level set in
the tolerance was used to determine
residues in wheat and barley
commodities.
Residues of the individual analytes
are detectable and quantifiable using
three separate analytical methods.
Residues of diflubenzuron are extracted
from wheat and barley with
dichloromethane and are purified with
deactivated florisil. An aliquot of the
extract is hydrolyzed with phosphoric
acid and the diflubenzuron is
partitioned into hexane. The resulting
extract is derivatized in
heptafluorobutyric anhydride (HFBA).
Quantification of diflubenzuron is
accompanied by gas chromatography
using electron capture detection.
The analytical method for
quantitation of the 4–chlorophenylurea
requires ethyl acetate extraction of the
residue from the crop matrix. Column
chromatography is utilized for clean-up
of the extract immediately prior to
derivitiation with HFBA. Derivatized
extracts are analyzed by gas
chromatography equipped with an
electron capture detector.
Analysis for the determination of PCA
residues in wheat and barley matrices
utilizes an internal standard method.
Samples of matrix to be analyzed are
fortified with an internal standard.
Residues of 14C-PCA and the internal
standard are subjected to acid and base
hydrolysis. The final extract is passed
through a florisil column for clean-up
and derivatized with HFBA in hexane.
An aliquot of the derivatized extract is
analyzed by gas chromatography
equipped with Mass Spectrometry
detection. Recovery of PCA is
determined from the combined peak
areas for the two mass spectral ions
obtained from the derivatized PCA
relative to the response factor derived
from the combined areas of the
corresponding two mass spectral ions of
the internal standard.

New Tolerance
(PPs) 5E6965, 5E6966, 5E6967. Interregional Project Number 4, 681
Highway 1 South, North Brunswick, NJ 08902-3390, proposes to establish
tolerances for residues of the insecticide diflubenzuron, (N-[[(4-
chlorophenyl)amino]carbonyl]-2,6-difluorobenzamide) and metabolites
convertible to p-chloroaniline expressed as diflubenzuron in or on the
following food commodities:
1. (PP) 5E6965 proposes to establish tolerances for barley, grain;
oat, grain; and wheat, grain at 0.06 parts per million (ppm); barley,
forage; oat, forage; and wheat, forage at 5.0 ppm; barley, hay; oat,
hay; and wheat, hay at 2.0 ppm; barley, straw; oat, straw; and wheat,
straw at 2.0 ppm; barley, aspirated barley fractions; oat, aspirated
oat fractions, and wheat, aspirated wheat fractions at 3.0 ppm; and
pummelo at 0.5 ppm.
2. (PP) 5E6966 proposes to establish tolerances for brassica,
leafy greens subgroup 5B; turnip at 8.0 ppm; eggplant at 1.0 ppm; and
okra at 1.0 ppm.
3. (PP) 5E6967 proposes to establish a tolerance for peanut at 0.2
ppm.
A practical analytical method for detecting and quantifying levels
of diflubenzuron in or on food with a limit of detection that allows
monitoring of the residue at or above the level set in the tolerance
was used to determine residues in wheat and barley commodities.
Residues of the individual analytes are detectable and quantifiable
using three separate analytical methods. Residues of diflubenzuron are
extracted from wheat and barley with dichloromethane and are purified
with deactivated florisil. An aliquot of the extract is hydrolyzed with
phosphoric acid and the diflubenzuron is partitioned into hexane. The
resulting extract is derivatized in heptafluorobutyric anhydride
(HFBA). Quantification of diflubenzuron is accompanied by gas
chromatography using electron capture detection.
The analytical method for quantitation of the 4-chlorophenylurea
requires ethyl acetate extraction of the residue from the crop matrix.
Column chromatography is utilized for clean-up of the extract
immediately prior to derivitiation with HFBA. Derivatized extracts are
analyzed by gas chromatography equipped with an electron capture
detector.
Analysis for the determination of PCA residues in wheat and barley
matrices utilizes an internal standard method. Samples of matrix to be
analyzed are fortified with an internal standard. Residues of 14C-PCA
and the internal standard are subjected to acid and base hydrolysis.
The final extract is passed through a florisil column for clean-up and
derivatized with HFBA in hexane. An aliquot of the derivatized extract
is analyzed by gas chromatography equipped with Mass Spectrometry
detection. Recovery of PCA is determined from the combined peak areas
for the two mass spectral ions obtained from the derivatized PCA
relative to the response factor derived from the combined areas of the
corresponding two mass spectral ions of the internal standard.
