The U.S. Environmental Protection Agency has recently approved the Maryland Department of Agriculture's request for a specific exemption under section 18 of FIFRA. This exemption allows the use of Dinotefuran to control Brown marmorated stink bugs in pome and stone fruit in Maryland orchards. This specific exemption expires October 15, 2015.

 

Under this specific exemption, Venom Insecticide, EPA Registration Number 59639-135, manufactured by Valent U.S.A. Corporation and Scorpion 35SL, EPA Registration Number 10163-137, manufactured by Gowan Company, LLC, to control Brown marmorated stink bugs in stone and pome fruit orchards. Venom Insecticide may be applied to stone and pome fruit at a maximum rate of 4 – 6.75 fluid ounces (0.179 – 0.302 lbs a.i.) of product per acre.  Scorpion 35SL Insecticide may be applied to stone and pome fruit at a maximum rate of 8 -12 fluid ounces (0.203 – 0.304 lbs a.i.) of product per acre.  For each of these products, a maximum of 2 applications can be made per acre per season and with a minimum 7 – day application interval.  No more than 0.608 lbs a.i. may be applied per acre per season.  Only foliar applications made by ground equipment are permitted under this specific exemption.

 

All applicable directions, restrictions, and precautions on the EPA registered products, as well as those outlined on the Section 18 labels use direction must be followed.  A maximum of 3,730 acres of stone and pome fruit may be treated in Maryland under this specific exemption.  A  12 – hour restricted entry interval (REI) and 3 – day preharvest interval (PHI) must be observed.

 

To help minimize exposure to pollinators, the following statement on the application timing must be observed. “Do not apply this product until after petal fall.”

 

 

In addition, the following statements from the section 3 labels are reiterated:

 

This compound is highly toxic to honey bees.

 

The persistence of residues and potential residual toxicity of dinotefuran in nectar and pollen suggest the possibility of chronic toxic risk to honey bee larvae and the eventual instability of the hive.

 

This product is toxic to bees exposed to treatment for more than 38 hours following treatment.

 

Please note that applying these products under this Section 18 the applicator must have in their  possession a copy of the approved Section 18 label for this use. 

 

The Maryland Department of Agriculture's Pesticide Regulation Section shall immediately be informed of any adverse effects resulting from the use of this pesticide in connection with this exemption.

 

Your help in disseminating this information is greatly appreciated.
