Abstract

The objective of this work was to evaluate the effect of liming and phosphate applications on the retention of triadimenol in microcolumns of soil material of a distrophic Red-Yellow Latosol (Typic Hapludox) and a distrophic Red Latosol (Typic Hapludox). Lime and phosphate applications decreased retention of triadimenol on LVAd samples (7.7% and 8.6%, respectively, for 2.67 and 10.68 kg ha-1 of the active principle). Lower retention of triadimenol was observed on LVd samples when lime and phosphate were applied separately (liming 7.2% and 3.9%, phosphate fertilization 10.1% and 6.8%, respectively, for 2.67 and 10.68 kg ha-1 of the compound). In spite of the amount of the chemical in soil solution being inferior to 1% of the dose applied, higher values of the chemical were found in the samples with lime and phosphate, singly or not in the LVAd and singly in the LVd.
