The Environmental Protection Agency is beginning registration reviews for 19 pesticides to determine if they still perform their intended tasks without unreasonable adverse effects on humans or the environment. Comments on each review are due by May 28. See the EPA’s notice for a list of pesticides under review.

The Environmental Protection Agency set pesticide tolerances for thiamethoxam in or on coffee (here), and emamectin benzoate in or on the cucurbit vegetable crop group 9 (which includes cucumbers, squash, watermelon, and muskmelon) (here). The agency also revised its pesticide tolerance for abamectin in or on cotton and strawberries (here). All of the new tolerances are effective March 27. Objections and requests for hearings must be submitted by May 28.

The Environmental Protection Agency established an exemption, effective March 22, to the tolerance for residues of banda de Lupinus albus doce (BLAD) in or on all food commodities, when applied as a fungicide and used in accordance with label directions and good agricultural practices.

The Environmental Protection Agency issued its periodic status report on Toxic Substances Control Act (TSCA) premanufacture notices (PMN), test marketing exemption (TME) applications, and notices of commencement (NOC) received from companies that intend to import or manufacture new chemicals. Comments are due by April 22, and must be identified by PMN or TME number. The status report covers the period from Dec. 1, 2012, to Jan. 11, 2013. See EPA’s notice for the list of PMNs, TMEs, and NOCs received by the agency.

The Environmental Protection Agency issued a final rule setting tolerances for the pesticide amitraz in honey and honey comb. The tolerances are effective March 20. Objections to the tolerances are due May 20.

The Environmental Protection Agency is extending until Aug. 18 its temporary tolerances for the insecticide tetrachlorvinphos (TCVP) in several meat and poultry products, according to a Federal Register notice set for publication March 13. EPA proposed the extension March 6 (see 13030605), and set an extremely short comment period that expires March 12, but isn't waiting for the comment period to expire to begin the process of publication of it's final rule. The temporary tolerances were set to expire March 18. EPA is extending the tolerances on its own initiative, to give itself more time to review information before making a final decision on tolerances for the insecticide. Requests for a hearing on the extension are due by May 13.

The Environmental Protection Agency said it received petitions to approve new uses for three pesticides containing currently registered active ingredients. Products covered by the petitions include a fungicide containing the active ingredient propiconazole; an insecticide with the active ingredient spirotetramat; an herbicide containing the active ingredient clomazone; a fungicide containing the active ingredient triflumizole; and an insecticide with the active ingredient quinoxyfen. Comments on the petitions are due April 5.

EPA will require efficacy data for pesticide products with prion-related claims, it said. The final rule also announced the availability of final test guidelines on generating product performance data for prion pesticide products. The final rule is effective April 29.
