USDA Deregulates the Agrisure Viptera™ Trait

What began as a bacterium isolated from a container of sour milk went on to become the protein Vip3A, and is now the Agrisure Viptera trait, which received deregulation from the U.S. Department of Agriculture on April 20, 2010.

Deregulation of this trait means that Syngenta is one step closer to providing growers the broadest spectrum of insect control available with the Agrisure Viptera 3111 trait stack. The Agrisure Viptera 3111 trait stack combines the Agrisure Viptera trait with the Agrisure 3000GT triple stack to deliver control of 14 yield- and quality-robbing insects, plus two options for herbicide tolerance. In field trials, the Agrisure Viptera trait has demonstrated an average yield advantage under corn earworm pressure of 14.3 bu/A, with yield gains of up to 32 bu/A under very heavy pressure.

Corn hybrids containing the Agrisure Viptera trait will be available for planting in the U.S. in 2011, following receipt of key import market approvals.

Furadan Update

Effective January 1, 2010, FMC will begin accepting returns of Furadan product inventory. Please contact your Furadan distributor or retailer to obtain specific instructions for product return.

On May 18, 2009 FMC issued a letter notifying Furadan customers that the EPA announced its final decision to revoke all crop tolerances for carbofuran effective December 31, 2009. FMC formally filed objections to the EPA’s tolerance revocation decision on June 30, 2009 and requested an expedited hearing before an EPA Administrative Law Judge to resolve our scientific differences with EPA, and firmly establish carbofuran’s safety to humans once and for all. However, on November 18, 2009, EPA denied FMC’s request for an administrative hearing. FMC immediately challenged EPA’s decision in the US Federal Appeals Court and asked the Court to temporarily postpone the tolerance revocations. On December 14, 2009, FMC received a favorable Court ruling that will expedite the Court’s determination of FMC’s right to an administrative hearing on EPA’s revocation of tolerances. The Court did not grant the request to temporarily postpone the tolerance revocations. As a result, the tolerance revocations as of December 31, 2009, will remain in effect. If the Court makes a final ruling in FMC’s favor that EPA must hold an administrative hearing, the hearing would likely begin in late spring or early summer 2010. A final ruling from the EPA administrative hearing would be expected later in 2010. FMC is committed to properly steward our products and regrets that EPA’s decision to revoke tolerances on a legally registered product has created confusion and uncertainty for our customers. At this time, while the revocation is in effect, we cannot recommend the use of Furadan and are taking steps to facilitate the return of unused product inventories.

EPA is seeking comments on the addition of the following statements to pesticide labels:

For agricultural products (with WPA labeling) it would add the following statement to the label. “In addition, do not apply this product in a manner that results in spray [or dust] drift that could cause an adverse effect to people or any other non-target organism or site.” --- which is in addition to the current labeling of --- “Do not apply this product in a way that will contact workers or other persons, either directly or through drift.”

For other commercially applied products the statement would read – “Do not apply this product in a manner that will contact workers or other persons, either directly or through drift. In addition, do not apply this product in a manner that results in spray [or dust] drift that could cause an adverse effect to people or any other non-target organism or site.”

For products intended solely for non-commercial application: “Do not apply this product in a way that could contact people, or that results in spray [or dust] drift that could cause harm to people, pets, property, aquatic life, wildlife, or wildlife habitat.”
