Dissipation patterns of acrinathrin and metaflumizone in Aster scaber

Abstract The establishment of preharvest residue limits (PHRLs) is important to minimize damage producer and consumers caused by agricultural products which pesticide exceeds maximum (MRLs). Dissipation patterns acrinathrin metaflumizone in Aster scaber greenhouse were studied during 10 days order determine a pre-harvest interval after application. Acrinathrin applied two different greenhouse, located Taean-gun (field 1) Gwangyang-si 2). Samples collected at 0, 1, 2, 3, 5, 7, insecticides recoveries analyzed LC–MS/MS HPLC–DAD ranged from 77.1 111.3%. half-lives residues respectively 3.8 5.9 field 1 9.2 4.5 2. PHRLs before harvesting A. 0.610 mg/kg 1), 0.946 2) for acrinathrin, 5.930 5.147 metaflumizone. This results can be used as basic data the PHRL .
