Dinotefuran Section 18 Emergency Exemption Registration in PA for BMSB Control
Posted: June 27, 2012
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, CA). The manufacturer’s recommended rates per acre for Scorpion of 8.0 to 12.0 fl. oz and for Venom of 4.0 to 6.75 oz 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 (12h REI). 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, 2012.
Based on our 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.
