DISSIPATION AND DETERMINATION OF Spiromesifen 240SC RESIDUES IN CUCUMBER AND EFFECT OF FOOD PROCESSING ON RESIDUE Wisam A. Al-Mashhadany, Saleh H. Samir,Abid Alkareem J.

ABSTRACT Laboratory and field studies were carried out at College of Agriculture- University of Baghdad and State Board for Plant Protection Ministry of Agriculture to study the dissipation of insecticide, [Spiromesifen] 240SC which used to control insects on Cucumber [plastic houses] by using High Performance Liquid Chromatography [HPLC] technique, besides evaluate the efficacy of some treatments on cucumber fruits [ washing in water and soap, peeling, immersion in saline solution and pickling] to reduce the amount of insecticide residue in ٧٦٩

However the residue dissipated faster in second spray. In fruits, the residue in first spray was mg/kg directly after treatment reduced to MRL [Maximum residue limit] in 7 days 0.19 mg/kg, however the dissipation was faster in second spray, the residue reached MRL after 4 days 0.21 mg/kg. Regarding treatment of washing the fruit, Oberon residue was dissipated in first and second spray after 3 days 0.21 mg/kg and 4 days 0.2 mg/kg respectively. Residue of Oberon reduced to 0.04 and 0.06 mg/kg after 21 days respectively. Also, treatment of peeling, saline solution and pickling reduced Spiromesifen residue in first spray to MRL after 2 days [0.21, 0.23 and 0.22] mg/kg respectively, while in second spray, Spiromesifen reduced dropped to MRL after 2 days [0.2, 0.17 and 0.18] mg/kg respectively for previous treatment.
