| Abstract | ||||
| The Objectives of this Study were to: 1. Study the persistence of (imidacloprid and fipronil) on tomato, (abamectin) on cucumber and (lambda-cyhalothrin) on orange fruits. 2. Investigate the effect of tested pesticide residues on some quality parameters (ascorbic acid, total protein, %Acidity, total soluble solid (%tss), %moisture and %dry matter) of fruits. The following points provide a summary of such study: 1. The recovery percentages of tested pesticides in tomato were. 2. Also, half – life time, t½ = 1.74, 1.60, 1.32 and 1.6 days in statistical equation for fipronil, imidacloprid, abamectin and lambda-cyhalothrin respectively. 3. Residues of (fipronil, imidacloprid) in /on tomato, (abamectine) in /on Cucumber and (lambda-cyhalothrin) in /on orange fruits at different time intervals. 1. Residues of fipronil in / on tomato at different time intervals 1.902, 1. 235, 0.637, 0.135, 0.099, 0.042 mg/kg after one hour, 1,3,5,7 and 10 days respectively. 2. Residues of imidaclopride in/on tomato at different time intervals 1.35, 1.02 ,0.71, 0.321, 0.075, 0.02 mg/kg after one hour, 1,3,5,7 and 10 days respectively. 3. Residues of abamectine in/on cucumber at different time intervals 0.621 , 0.256, 0.092, 0.042 mg/kg after one hour, 1,3, and 5 days respectively. 4. Residues of lambda-cyhalothrin in/on orange at different time intervals 1.02,0.963,0.521,0.201,0.064,0.015 mg/kg after one hour, 1,3,5,7 and 10 days respectively. | ||||
