The work was carried out with the objective of verifying the association of carbofuran presence in the soil profile analyzing both form and time of application with efficiency parameters of irrigation systems used in the District of Irrigation of Gorutuba (DIG) in Janaúba, MG. Fourteen rural properties were selected that presented a great variability in the performance of irrigation parameters and in the distribution of the carbofuran in the soil profile. The parameters TAP (Time of application of the product), QIAAP (amount of the applied active ingredient) and Perc (Depth of percolated water), presented a clear association with the distribution of the pesticide in the soil profile. These parameters showed that farmers of the DIG, who apply excess water through irrigation and have bad management and also use pesticide indiscriminately may seriously pollute the soil and, consequently, the water, compromising in the medium term the sustainability of their activities.
