Abstract
Profenofos and dimethoate at half. equal and twice recommended rate were applied onto cucumber plants. The resleues were determined uSing gas chromatograph equipped with flame photometric detection. The residue levels of protenotos on cucumber fruits at harvesling time were 0.54, 1.32. and 1.90 mg/kg for half, equal, and twice recommended rate. respectively. The corresponding values of dimethoate were 1.13. 3.85, and 4.60 mglkg, respectively. Profenofos and dimethoate showed inhibitory effects on rat brain AChE activity with 150 values equal to 16 and 370 11M, respectively. The predicted KI values for profenofos and dimethoate are 1.4 X10l and 0.06 X 10) M' min", respectively. The twice-recommended field rate or dimethoate and profenofos caused 54.1 and 36.4 as a percent Inhibition of control In vivo of rat brain AChE, respectively. However, profenofos was more potent inhibitor than dimethoate (In vitro).
