title: Dissipation and decontamination of bifenthrin residues in tomato (Lycopersicon esculentum Mill).
abstract: A field experiment was conducted at the Research Farm of CCS HAU, Hisar to study the dissipation and decontamination behavior of bifenthrin on tomato crop following the application of 25 g a.i ha(-1) (T(1)) and 50 g a.i ha(-1) (T(2)). Samples were collected periodically on the sampling days after applications. Residues were reached below detectable level of 0.005 mg kg(-1) on 10(th) day after application showing half-life period of 1.83 and 2.05 days at room temperature and 2.02 and 2.32 days under refrigerated condition for single and double dose, respectively. Processing was found effective in reducing the residues of bifenthrin in tomato fruits. Maximum reduction (42.10-45.23 %) was observed by washing + boiling followed by washing (16.66-19.04 %). Reduction was slightly less when samples were stored under refrigerated conditions as compared to room temperature conditions.
