EPA has approved a new Bidrin label, completing the re-registration process for this important insecticide. Bidrin has now met all of the EPA's current re-registration requirements.

All future production of Bidrin will carry the newly approved label on the container. Existing stocks of Bidrin may still be used according to the label directions on the container. Several significant changes are in the newly approved label.

Mixers and loaders must now use a closed handling system that meets the requirements listed in the Worker Protection Standards.

The restricted-entry interval (REI) has been increased to six days.

The overall seasonal maximum use rate has been reduced to 1.2 pounds of active ingredient per acre with the following conditions: Only a single application of up to 0.2 pound active ingredient per acre can be applied from emergence to pre-square cotton. An additional 1 pound of active ingredient per acre can be applied from the first bloom stage of cotton until 30 days prior to harvest. The rates for individual applications during this late-season period range from 0.25 pound active ingredient per acre to 0.5 pound active ingredient per acre.

There is a minimum interval of 14 days between applications.

The newly approved label continues to allow Bidrin to be applied by ground-driven sprayers or by aircraft.

Local AMVAC representatives can answer any questions concerning the implementation of the new label requirements.
