A field experiment was performed to determine the effects of tembotrione and atrazine residues in soil on sugar beet eight months after herbicide application. The treatments included sugar beet cultivation with tembotrione-contaminated soil (50.4 g a.i. ha-1), tembotrione (100.8 g a.i. ha-1), tembotrione and atrazine (50.4 g a.i. ha-1 + 2 L a.i. ha-1), tembotrione and atrazine (100.8 g a.i. ha-1 + 2 L a.i. ha-1), atrazine (2 L a.i. ha-1) and soil without herbicide application. In general, in comparison to the control, when sugar beets were grown following any of the herbicide treatments, the crop dry biomass was reduced. However, only treatments sprayed with a high rate of tembotrione significantly reduced sugar beet yield.
