Dinotefuran gets emergency exemption registration in Penn. for BMSB control

As in 2011, the insecticide active ingredient dinotefuran received a special Section 18 Emergency Exemption Registration from EPA to help control brown marmorated stink bug (BMSB) in Pennsylvania on both pome and stone fruit.

The active ingredient, dinotefuran, belongs to IRAC Group 4A (neonicotinoids), and is available for use on stone and pome fruit under two trade names: Scorpion 35SL(manufactured by Gowan Company, Yuma, Az.) and Venom (manufactured by Valent USA Corp, Walnut Creek, Cal.).

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 the orchards.

No more than two applications of dinotefuran containing products are allowed per season. Both Scorpion and Venom can be used up to 3 days before harvest (3d PHI) 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 October 15.

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