Abstract
Supervised field trial was conducted to study the dissipation rates of two widely used acaricides hexythiazox (Makoyt 10%WP) and abamectin (Veractin 25 % EC) on strawberry under Egyptian climatic condition. Samples were collected randomly at successive intervals after pesticides spraying at recommended rate of applications. The samples were extracted and cleaned up using QuEChERS method and quantified by HPLC- equipped with Diode-Array Detector (DAD). The LOD&LOQ of hexythiazox and abamectin were 0.01mg/kg and 0.03mg/kg, respectively.The recovery of the tested pesticides was 90%and 81 %.The results showed that, the initial deposits were 3.64 and 1.31mg/kg and the calculated half-life’s (t½) were 2 and 1.5 days in strawberry for hexythiazox and abamectin, respectively. However, Pre harvest intervals (PHI) on strawberry were 4 and 7 days for hexythiazox and abamectin, respectively
