US EPA identifies Flumiclorac-pentyl in the category of a "Reduced-Risk Pesticide"

March 8, 2006.

90-Day oral toxicity-- nonrodents (dog) - increased clotting time in females

Reproduction and fertility effects (rat) - increased kidney weight in males and females and nephropathy in males; decreased body weight/body weight in F2 pups

Chronic toxicity-- dogs - decreased body weight gain in male; increased clotting time, increased globulin levels, and increased alpha-2 fraction of the serum protein electrophoresis in females

Cytogenetics - weak, positive response without activation

VALENT U.S.A. Corporation. Pesticide petition PP 3F6767. Proposal to establish a tolerance for residues of the herbicide flumiclorac pentyl ester, pentyl [2-chloro-4-
fluoro-5-(1,3,4,5,6,7-hexahydro-1,3-dioxo-2H-isoindol-2-yl)phenoxy]-
acetate in or on

The residue analytical method for enforcement purposes uses gas-liquid chromatography with a thermionic-specific detector. The enforcement method has been validated at an independent laboratory and by EPA. The method has been submitted to the Food and Drug Administration for publication in the Pesticide Analytical Manual, Vol. II (PAM II).

Note: see Comments submitted to US EPA on this pesticide petition.

This notice announces the availability of EPA's Tolerance Reassessment Decision (TRED) for the pesticide flumiclorac pentyl, and opens a public comment period on this document, related risk assessments, and other support documents. EPA has reviewed the low risk
pesticide flumiclorac pentyl through a modified, streamlined version of the public participation process that the Agency uses to involve the public in developing pesticide tolerance reassessment and reregistration decisions.

Flumiclorac pentyl is a post-emergence herbicide used on field corn, soybeans and non-crop areas, such as: industrial sites, airports, military installations, roadsides and associated rights-of-way, and other similar areas to control a selected group of broadleaf weeds, specifically morning-glory and velvet leaf. Although there are no labeled residential homeowner uses, there is potential risk for non-occupational exposure from other treated areas, such as golf courses, athletic fields, recreational areas, schools, apartment buildings, etc.

Consolidation of Certain Food and Feed Additive Tolerance Regulations. FINAL RULE. This final rule transfers certain of the pesticide food and feed additive regulations that are now in 40 CFR parts 185 and 186 to part 180. EPA is consolidating these regulations because as a matter of law all of pesticide tolerances are now considered to be regulated under section 408 of the Federal Food, Drug, and Cosmetic Act as amended by the Food Quality Protection Act (Pub. L. 104-17) and they no longer need to be separate. EPA is also amending 40 CFR 180.1 by adding a definition for the term ``food commodity.'' 

VALENT - Pesticide Tolerances and Feed Additive Regulation.. - FINAL RULE. These rules establish tolerances for residues of the herbicide flumiclorac pentyl in or on the raw agricultural commodities field corn, grain; field corn, fodder; field corn, forage; and soybean, seed at 0.01 ppm, and in or on the feed additive commodity soybean hulls at 0.02 ppm.

VALENT - Pesticide Petition Tolerance for a feed additive regulation to permit residues of Resource Herbicide in or on soybean hulls at 0.02 ppm. [Note from EC: The FR is not online for 1993. This comes from a USDA bulletin on the PMEP website.
