Bifenthrin was first evaluated at the 1992 JMPR and MRLs of 0.05* mg/kg were recommended for barley, maize and wheat to cover field applications. Information was provided to the 1995 Meeting on the use of bifenthrin as a grain protectant on stored grain but no new recommendations were made for cereals because a number of points needed to be clarified. The following information was listed as desirable.
Efficiency of extraction by acetone of aged bifenthrin residues.
National MRLs for bifenthrin relating to uses on stored grains.
Fate during the commercial milling of wheat.
Fate during the baking of bread.
Fate during commercial making of barley.
Information on milling and baking studies with bifenthrin-treated wheat was provided.
