The aim of this study was to detect the pesticide residues (Trifluralin, Metaclor and Prometrin) from soil and to estimate their remanence in soil at 7 respectively at 14 days after administration. The researches were performed over a period of one year. The samples were analyzed by (GC) gas chromatographic method. The obtained results showed that the most rapid degradation was recorded for Trifluralin which was found, after 14 days from the administration, at a concentration of 21% relative to the administered amount. It followed Metaclor with 56% out of initial dose. The smallest degradation rate was noticed for Prometryn which was refound in proportion of 60% after 14 days.
