US proposes approval for Gowan's fenazaquin

The US EPA has proposed the registration of Gowan’s insecticide/acaricide, GWN-1708 (fenazaquin), for the control of whiteflies and mites on ornamentals, Christmas trees and non-bearing fruit and nut trees. It would be the first approval for use of the active ingredient, which already has import approvals for apples, pears and citrus fruit. Fenazaquin belongs to the quinazoline class, which is a new class of pesticide chemistry in the US, the EPA notes. Gowan acquired fenazaquin and the Magister brand from Dow AgroSciences in 2002 ( Agrow No 393, p 3). It applied for US approval in 2007. The approval decision is open to public comment until March 23rd.
