Cotton growers must no longer document failures of registered alternative aphicides before Furadan can be used.

The U.S. Environmental Protection Agency has approved a FIFRA Section 18 Emergency Specific Exemption request by the Texas Department of Agriculture for the use of carbofuran (Furadan 4F Insecticide/Miticide) to control cotton aphid on cotton in Texas.

The original approval contained an outdated provision that would have required growers to first document treatment failures of other previously approved but ineffective and expensive pesticides before they could use Furadan.

Texas Agriculture Commissioner Susan Combs and her staff have been battling this unnecessary provision since last year.

On March 28, 2001, EPA approved an amendment to the specific exemption numbered 01-TX-05. The approval notice and the amendment can be obtained from the TDA web site at: http://www.agr.state.tx.us/pesticide/18crops.htm

In a recemt press release, TDA said the amendment removes item No. 4 on the approval notice requiring the use of flowable carbofuran to “only those acres that can provide documentation of treatment failures attributable to resistance, or in the absence of such documentation, growers are allowed to use flowable carbofuran only if application of a recommended aphicide has failed (less than 80 percent control) and aphid populations have again reached the treatment threshold.”

This change, means cotton growers must no longer document failures of registered alternative aphicides before Furadan can be used. If and when populations build to threshold levels, carbofuran may be used as the product of choice.

TDA does not need to approve the use of Furadan byExtension districts as has been the requirement in the past.

All other provisions of the EPA approval notice must be followed and of course, always read and follow label directions.
