New Residue Tolerances Sought in U.S.

WASHINGTON - ec 15/10 - SNS -- The Environmental Protection Agency (EPA) in the United states has been petitioned to establish minimum residue levels for tepraloxydim, isoxaflutole, fenamidone, flutriafol and hexythiazox on various products.

An application from BASF Corporation proposes to establish a tolerance for residues of the herbicide tepraloxydim in field peas, dry edible beans and sunflower.

It would cover the chemical (2-[1-[[[(2E)-3-chloro-2-propenyl]oxy]imino]propyl]-3-hydroxy-5-(tetrahydro-2H-pyran-4-yl)-cyclohexene-1-one) and its metabolites convertible to GP (3- (tetrahydropyran-4-yl)pentane-1,5- dioic acid) and OH-GP (3-hydroxy-3-(tetrahydropyran-4-yl)pentane-1,5- dioic acid), calculated as tepraloxydim, in or on pea and bean, dried shelled, except soybean, subgroup 6C at 0.10 parts per million (ppm); and sunflower, subgroup 20B at 0.25 ppm for imported commodities. The limit of quantitation (LOQ) is 0.05 ppm for each analyte, parent and metabolite.

Cheminova A/S proposes to establish a tolerance for residues of the fungicide flutriafol, [()-[alpha]-(2-fluorophenyl)-[alpha]- (4-fluorophenyl)-1H-1,2,4-triazole-1-ethanol], including its metabolites and degradates, in or on banana, whole (import tolerance) at 0.50 ppm. Adequate enforcement analytical methods for determining flutriafol in or on appropriate raw agricultural commodities and processed commodities are available for the established and proposed tolerances.

Isagro S.p.A. proposes to establish a tolerance for residues of the fungicide tetraconazole, 1-[2-(2,4-dichlorophenyl)-3-(1,1,2,2- tetrafluoroethoxy)propyl]-1H-1,2,4-triazole, in or on corn; field, forage; field, grain; field, stover; pop, grain; and pop, stover at 1.0, 0.01, 1.5, 0.01 and 1.5 ppm, respectively.

Bayer CropScience proposes to establish a tolerance for the combined residues of the herbicide isoxaflutole, 5-cyclopropyl-4-(2-methylsulfonyl-4- trifluoromethylbenzoyl) isoxazole and its metabolite 1-(2- methylsulfonyl-4-trifluoromethylphenyl)-2-cyano-3-cyclopropyl propane- 1,3-dione (RPA 202248), calculated as the parent compound, in or on soybean at 0.05 ppm; and soybean, aspirated grain fractions at 0.25 ppm.

Bayer CropScience proposes to establish a tolerance for residues of the fungicide fenamidone, (4H-Imidazol-4-one, 3,5-dihydro-5-methyl-2-(methylthio)-5- phenyl-3 (phenylamino)-, (S)-), in or on grain, cereal, group 15 (except rice) at 0.1 ppm; grain, forage, group16 (except rice) at 0.3 ppm; and grain, stover, group 16 (except rice) at 0.5 ppm.

Syngenta Crop Protection proposes to establish a tolerance for residues of the herbicide fluazifop-p- butyl, butyl(R)-2-[4-[[5-(trifluoromethyl)-2- pyridinyl]oxy]phenoxy]propanoate, and the free and conjugated forms of the resolved isomer of fluazifop, (R)-2-[4-[[5-(trifluoromethyl)-2- pyridinyl]oxy]phenoxy]propanoic acid, expressed as fluazifop, in or on cotton, undelinted seed at 0.9 ppm; and cotton, gin byproducts at 0.8 ppm.

Cheminova A/S proposes to establish rotational crop tolerances for the indirect or inadvertent residues of the fungicide flutriafol, [()-[alpha]-(2-fluorophenyl)-[alpha]-(4-fluorophenyl)-1H-1,2,4- triazole-1-ethanol], including its metabolites and degradates, in or on sweet corn, field corn and cotton raw agricultural commodities (corn, sweet, forage at 0.05 ppm; corn, sweet, stover at 0.09 ppm; corn, sweet, kernels plus cob with husks removed at 0.01 ppm; corn, field, forage at 0.10 ppm; corn, field, stover at 0.07 ppm; corn, field, grain at 0.01 ppm; cotton, undelinted seed at 0.01 ppm; and cotton, gin byproducts at 0.05 ppm) grown in fields previously planted with soybeans that were treated with flutriafol. Residues of flutriafol in sweet corn, field corn and cotton raw agricultural commodity products can be determined by GC with mass selective detection (GC/MSD).

Cheminova A/S proposes to establish a tolerance for residues of the fungicide flutriafol, [()-[alpha]-(2-fluorophenyl)-[alpha]- (4-fluorophenyl)-1H-1,2,4-triazole-1-ethanol], including its metabolites and degradates, in or on corn, field, forage at 4.0 ppm; corn, field, stover at 6.0 ppm; corn, field, grain at 0.01 ppm; corn, field, flour at 0.03 ppm; corn, field, oil at 0.07 ppm; corn, field, meal at 0.03 ppm; corn, pop, stover at 6.0 ppm; corn, pop, grain at 0.01 ppm; grape at 1.1 ppm; grape, raisin at 2.5 ppm; peanut at 0.08 ppm; peanut, hay at 18 ppm; fruit, pome (Crop Group 11) at 0.60 ppm; fruit, stone (Crop Group 12) at 0.80 ppm; beet, sugar, root at 1.5 ppm; beet, sugar, tops at 2.5 ppm; beet, sugar, refined at 0.70 ppm; beet, sugar, molasses at 1.0 ppm; beet, sugar, dried pulp at 1.0 ppm; wheat, forage at 25 ppm; wheat, hay at 9.0 ppm; wheat, straw at 6.0 ppm; wheat, grain at 0.15 ppm; wheat, grain, bran at 0.20 ppm; wheat, grain, germ at 0.20 ppm; barley, hay at 9.0 ppm; barley, straw at 6.0 ppm; barley, grain at 0.15 ppm; barley, grain, bran at 0.20 ppm; buckwheat, grain at 0.15 ppm; oats, forage at 25 ppm; oats, hay at 9.0 ppm; oats, straw at 6.0 ppm; oats, grain at 0.15 ppm; oats, grain, bran at 0.20 ppm; rye, forage at 25 ppm; rye, straw at 6.0 ppm; rye, grain at 0.15 ppm; cattle, liver at 0.12 ppm; goat, liver at 0.12 ppm; horse, liver at 0.12 ppm; sheep, liver at 0.12 ppm; and milk at 0.02 ppm. The proposed tolerance for fruit, pome, which is based on new field trial data for pears and previously submitted data for apples, will replace the current tolerance for apples at 0.20 ppm.

Gowan Company proposes to amend residues of the insecticide hexythiazox (trans-5-(4-chlorophenyl)-N-cyclohexyl- 4-methyl-2-oxothiazolidine-3-carboxamide) and its metabolites containing the (4-chlorophenyl)-4-methyl-2-oxo-3-thiazolidine moiety, by establishing a tolerance in or on grain, aspirated fractions at 0.5 ppm; removing the geographical restriction for the existing tolerances for hexythiazox on corn, field, forage; corn, field, grain; and corn, field, stover; and increasing the tolerance for corn, field, stover from 2.5 ppm to 6.0 ppm.
