Diflubenzuron application rates

Diflubenzuron application rates between 28.0 and 56.0 g/ha (0.025-0.05 pounds/acre) or 2.5-16.0 p,g/L are highly effective against pestiferous aquatic dipterans, including representative chaoborids, chironomids, and culicids. 

The presence of sediments in diflubenzuron marine microcosms results in rapid removal from seawater and ultimately a reduction in mortality of larval crustaceans (Table 17.2) (Cunningham et al. 1987). But marine sediments that exceed 200 pg diflubenzuron/kg — levels normally encountered at application rates for control of salt marsh mosquitoes — could be detrimental to juvenile and adult crustaceans that consume detritus and organic matter on the surface of the marsh or at the water-sediment interface (Cunningham and Myers 1986 Cunningham et al. 1987).
