Abstract: An experiment was carried out at Shambat Agricultural Farm, College of Agricultural Studies, Sudan University of Science and Technology – Khartoum, North-Sudan in order to study the effect of Folimat 800 and Icaros pesticides residues on the soil fertility and carrot growth. Both pesticides were applied at concentrations of 1.92 Kg ha-1 and 249.2 ml ha-1 (recommended dose) respectively, 2.88 Kg ha-1 and 371.8 ml ha-1 (excessive dose) respectively, to evaluate their effect on plant growth and soil fertility. The results revealed that, both pesticides significantly increased carrot vegetative growth at the recommended doses (shoot dry weight, shoot fresh weight, leaf area, plant height), but on contrary, negatively affected at the excessive doses. Moreover, the results indicate that applying both pesticides slightly increased soil CEC and decreased K+, Na+ and P contents.
