ABSTRACT
The effects of field-aged residues of the new semi-synthetic spinosyn insecticide spinetoram (Dow AgroSciences, Indianapolis, IN) and the spinosad bait GF-120 (Dow AgroSciences, Indianapolis, IN) on mortality of apple maggot fly, Rhagoletis pomonella (Walsh), were determined in Washington State. Mortality caused by spinetoram (100 g a.i./ha) sprayed on apples and aged 7 d was significantly lower than that caused by fresh spinetoram. Spinetoram (100 and 75 g a.i./ha) aged ...
