The intent of this network is to inform interested parties of recent or impending pesticide use cancellations, tolerance revocations and other items of agricultural interest. To the best of our knowledge, the uses mentioned here, unless otherwise indicated, will not appear on any label registered by the USEPA following the uses expected cancellation. We recommend that you express any concerns or questions you have to the contact mentioned below or your NAPIAP State Liaison Representative. If you wish to contact us at USDA, our phone number is (301) 504-8846, and our fax number is (301) 504-8063.

chlorothalonil (Bravo)

ISK Biotech Corporation has submitted applications to the USEPA to delete from their products of the fungicide, chlorothalonil, the sites of ONIONS(GREEN), SHALLOTS, and LEEKS due to the potential that residues may exceed established tolerances. Other registrants of chlorothalonil are expected to follow their lead, but the USEPA has not published these deletions yet. ISK Biotech plans to retain all other registered sites including dry bulb onions, garlic, and onions grown for seed, and may reconsider the deletion of shallots in light of the USEPA's new crop grouping list. ISK Biotech regrets these deletion actions but does not feel that a new use pattern greater than the present 14-day PHI would give reasonable disease control, even though longer PHIs could lower residue levels.

permethrin (Pounce, Ambush)

The registrants of permethrin plan to delete the use of CHERRIES and WATERCRESS from their labels of the insecticide, permethrin, due to the cost of reregistration. This action has not yet been submitted to the USEPA and the FMC Corporation will support the uses if another party wishes to develop the required residue data.

dichlorvos (DDVP)

The USEPA has revoked the food additive tolerances for residues of the insecticide, dichlorvos, in or on PACKAGED OR BAGGED NONPERISHABLE PROCESSED FOOD as of 3/10/94. The proposal for this action was listed here on 12/1/91. This action is in response to a petition submitted in March of 1991 claiming that these tolerances violate the Delaney Clause in Section 409 of the FFDCA. The USEPA found that dichlorvos does induce cancer in animals and does violate the Delaney Clause. Written objections, requests for a hearing, or requests of stays, with reference to OPP-300237A, should be addressed to the Hearing Clerk at EPA by 12/10/93.
