Popis: The objective of this study was evaluate the interacting effects on absorption and translocation of 14C-mesotrione and 14C-atrazine mixture for morning glory (Ipomoea hederifolia) control. The mixture of atrazine + mesotrione was shown to be additive and synergistic by visual assessment in relation to expected control, depending on the dose and evaluation period. Absorption of 14C-atrazine alone (62.5%) and as a mixture (60%) in morning glory was higher than in the treatments with 14C-mesotrione alone (42.8%) and as a mixture (46.6%). However, 14C-mesotrione alone showed a higher translocation (8.6%) than 14C-mesotrione + atrazine (2.5%), indicating that the mixture decreased the translocation of this herbicide.
