Dinotefuran received emergency exemption registration in Pennsylvania

The insecticide active ingredient dinotefuran has received a special Section 18 Emergency Exemption Registration from EPA to help control brown marmorated stink bug (BMSB) in Pennsylvania on pome and stone fruit.

Dinotefuran, belongs to Insecticide Resistance Action Committee Group 4A (neonicotinoids), and is available for use on stone and pome fruit under two trade names: Scorpion 35SL (manufactured by Gowan Company) and Venom (manufactured by Valent USA Corp). The manufacturer’s recommended rates per acre for Scorpion of 8.0 to 12.0 fluid ounces and for Venom of 4.0 to 6.75 ounces should provide effective control of BMSB adults and nymphs in orchards.

No more than two applications of dinotefuran containing products are allowed per season.

Both Scorpion and Venom can be used up to three days before harvest and have a 12-hour restricted entry interval. According to the product label, dinotefuran containing products are highly toxic to bees exposed to treatment for more than 38 hours following treatment.

The Section 18 Emergency Exemption registration for both products will expire on Oct. 15, 2012.

Based on direct contact laboratory bioassays conducted this past winter at Penn State University, both dinotefuran containing insecticides were very effective against BMSB adults and nymphs, comparable to or better than other available materials.
