Abstract EN
Present study was carried out in laboratory for estimating movement of three insecticides (Dursban,Karate,DDVP) in three textural different soils there could be reach to ground water and contaminated it.The insecticides motion had been proved via hydraulic conductivity property basis on liquid and soil features .However the soil samples brought from three locations which were (najaf city ,kufa city,alzarka village ) there classified as : 1th orthids; 2th, 3th torifluvents) respectively.
Meanwhile soil columns prepared in three replicates to each soil.
Then hydraulic conductivity measured with (head constant method)to sandy soil , (variable charge method)to others Dunnett's method to compare of means there were showed in results as: 1- DDVP 2.915 (cm.minut-1)> Karate 2.443 (cm.minut-1) > 1.394 Dursban (cm.minut-1) through sandy soil.
2- Karate 2.801(cm.minut-1) > DDVP1.442 (cm.minut-1)> 1.207 (cm.minut-1) Dursban through loamy soil.
3_ DDVP 0.386 (cm.minut-1)> Karate 0.305 (cm.minut-1) > 0.702 (cm.minut-1) Dursban through clay soil.
The point is that DDVP, Karate can access to the ground water in sandy ,loamy soils than Dursban but all of those cannot access it in clay soil.
Conclusion *Using these insecticides is more suitable with heavy soil from soil and water management concept.
** There was no risky of Dursban apply as chemical chlorpyrifos group under recommended doses from plant protection side.
***Relying on first order equation as kinetic way discovered how much is insecticidal resides on soil surface with no additional do.
