الملخص الإنجليزي

Ultrasonic Extraction method followed by gradient HPLC was carried out for the simultaneous determination of four insecticides are [imidacloprid (Imi), thiamethoxam (Thi), indoxacarb (Ind) and abamectin (Aba)] used to combat the major insect pests in Iraq, whitefly, Dubas Bug, worms fruits as well as to combat the spiders – dream respectively in eco-soil samples.

The extraction recovery was in the range of 99.77 to 109.1 %.

The dissipation kinetics and residual levels of these insecticides in soil sample was studied under field ecosystem.

The half-life of the mix insecticides was determined.

The half-life was in range of 0.38 to 4.06 days with the soil samples were brought from the Agricultural Land called Nahrawan located in the south-east of Baghdad.

Such these studies contributed to scientific bases to know the behaver the deferent insecticides mixtures form and to determinate the battier dose uses in application.

The coefficient variation (C.V %) was less than (14.1%).
