LG Life Sciences, Ltd.
EPA has received a pesticide petition (4E6863) from LG Life Sciences, Ltd., c/o Landis International, Inc., P.O. Box 5126, Valdosta, GA 31603-5126 proposing pursuant to section 408(d) of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a(d), to amend 40 CFR part 180 to establish tolerances for residues of ethaboxam (LGC-30473), (RS)-N-(alpha-cyano-2-thenyl)-4-ethyl-2-(ethylamino)-1,3-thiazole-5-carboxamide, in or on grapes, grape juice, raisins, and wine. The tolerances are set at the following values: Grapes at 3.5 parts per million (ppm), grape juice at 3.3 ppm, raisins at 5.8 ppm, and wine at 2.5 ppm.
A program of 19 residue trials was conducted in both Northern and Southern Europe over a 2-year period (2001-2002) on vines. In Northern Europe trials were conducted in France and Germany, while in Southern Europe the trials were in France, Italy, and Spain. Applications of ethaboxam 10% SC were made at the proposed GAP of 5 x 200 gram active substance/hectare (g a.s./ha) with a 21-day post harvest interval (PHI). Of the 19 trials, 8 were conducted as decline studies, with 5 in Southern Europe and 3 in Northern Europe. Residue levels in grapes ranged from less than the limit of detection (< 0.005 ppm) to 3.4 ppm with a mean value of 1.07 ppm. The proposed EU maximum residue level (MRL) for grapes is 3.5 parts per million (ppm) and the MRLs for grape processed commodities based on the concentration/dilution factors determined in the processing study are 2.5 ppm for young wine, 1.3 ppm for wine, 2.3 ppm for juice, and 5.8 ppm for raisins.
These proposed MRLs were combined with a program of seven trials conducted in 2004. This program was conducted in Chile (three trials), Australia (two trials), Argentina (one trial), and Mexico (one trial). Residues were analyzed resulting from five applications of ethaboxam 10% SC at 2 or 4 Liter/hectare (L/ha), sampled at 21 days following the final application. No residues of ethaboxam were detected above the limit of detection of 0.002 ppm in any non-treated samples from any of the trials. Residues of ethaboxam detected in grapes ranged from 0.183 to 1.827 ppm in samples sprayed at a rate of 2 L/ha and from 1.121 to 7.072 ppm for grapes sprayed at a rate of 4 L/ha. Residues detected in juice (must) samples were between 0.64 and 3.24 ppm (2 L/ha rate); in raisins residues were between 0.39 and 1.68 ppm (2 L/ha rate); in wine residues were between 0.11 and 0.49 ppm (2 L/ha rate). Combining the residues from the two programs the following tolerances are proposed: Grapes at 3.5 ppm, grape juice at 3.3 ppm, raisins at 5.8 ppm, and wine at 2.5 ppm.
Neither livestock feeding studies or livestock metabolism, distribution and expression of residue studies are required, as vines will not be utilized for feeding. The storage stability of ethaboxam was assessed in grape homogenates during freezer storage (- 18° C). The results of the analysis show that ethaboxam was stable for a minimum of 17 months.
The primary metabolic pathways of ethaboxam in plants were established in grapes, tomatoes, and potatoes. Extensive metabolism occurred in the grape. The proposed bio-transformation pathway for ethaboxam in grapes is the formation of LGC-35523 from ethaboxam (by photolytic degradation) and incorporation of LGC-35523 into natural products (sugars). In the potato, most of the parent compound was metabolized and incorporated into starch. Following acid hydrolysis of the starch fraction to glucose, a substantial proportion of the radiolabel was converted to glucosazone. It was therefore concluded that the radiolabel was incorporated into the starch backbone and formed part of the carbohydrate pool. In the tomato, fruit taken at harvest showed that the major component at harvest was unchanged ethaboxam, accounting for 49-57% total radioactive residues. Studies of the absorption, distribution, metabolism and excretion of ethaboxam (LGC-30473) were carried out using [14 C]-LGC-30473,14 C-thiophene LGC-30473 and [14 C-thiazole] LGC-30473 dosed separately. Studies were performed in rats of the same strain used for toxicity assessments at dose levels of 10 or 150 milligrams/kilogram (mg/kg) and oral gavage dosing in a 1%methylcellulose, 0.1% Tween 80 vehicle.
Excretion of radioactivity following either a single dose of [14 C-thiophene or14 C-thiazole] LGC-30473 or 14 consecutive doses of [14 C-thiazole] LGC-30473 was rapid with <90% of radioactivity eliminated in urine or faeces within 48 hours. Faecal excretion (66-92% of dose in 120 hours (h)) substantially exceeded urinary excretion (13-30% of dose in 120 h) with the percentage excreted in the urine higher at the lower dose. These factors suggest capacity limited absorption. This was supported by the pharmacokinetic data which showed a slightly less than dose proportional increase in Cmax and AUC (area under the plasma concentration-Start Printed Page 38921time curve) between the 10 and 150 mg/kg doses (dose ratio 15, AUC ratio 11). Substantial radioactivity was detected in bile suggesting first-pass metabolism was significant. Tmax was around three times longer at the high dose level (3-6 hours (h) at 150 mg/kg versus 1-2 h at 10 mg/kg). The plasma elimination half-life of 31-41 h was similar for both doses. The blood cell elimination half-life was considerably longer at 69-162 hours for both doses. AUC 120 was higher in blood plasma following 14 doses at 10 mg/kg/day than following one dose (~2 fold) but more notably higher in blood cells (~5 fold).
Distribution of radioactivity after a single dose at 10 or 150 mg/kg or 14 consecutive doses at 10 mg/kg was similar at both dose levels and was highest in thyroid (thiazole label only), liver and blood cells. Concentrations 120 hours after the 14th dose were 5-15 fold higher than after the single dose, but all tissue accumulation was low. There were no substantial differences in distribution or excretion pattern between sexes. Extent of absorption, assessed in biliary excretion experiments, was similar between the sexes at 10 mg/kg (71-72% dose) but higher in females at 150 mg/kg (males, 48% dose; females 61% dose). All elements of this study indicate similar results for both labels and there was little evidence of cleavage of the intact molecule. Five major metabolites were identified each accounting for >5% dose: LGC-32794, LGC-32800, LGC-32801, LGC-32802, and LGC-32803. In one pathway, ethaboxam was N-de-ethylated to LGC-32794 followed by oxidation of the thiazole sulphur to LGC-32800. Ethaboxam also underwent enolization. In a second pathway the enol form underwent hydrolysis to the amide LGC-32801. In a third pathway the enol underwent sulphate conjugation to LGC-32802 and hydroxylation/sulphate conjugation to LGC-32803. Ethaboxam was detected as a major component of faecal extracts at both dose levels. Destructive catabolism of the molecule appeared to be negligible.End Supplemental Information
