Abstract

The objective of this study was to evaluate the phytotoxicity of saflufenacil in Brazilian Cerrado soils with contrasting properties. Experiments were performed in a factorial design. To quantify herbicide phytotoxicity, the bioassay technique was used and cucumber (Cucumis sativum) was selected as a test plant. A greater reduction of the dry mass was observed for bioindicator plants in comparison to others in the Typic Dystrophic Red Latosol. A rate of 11.76 g i.a. ha-1 was required to reach 50% reduction of the plant dry mass for this soil. Rates of 30.87; 44.10, and 119.56 g i.a. ha-1, respectively, are needed to achieve a 50% reduction of the plant dry mass in the Typic Acric Red Latosol, Typical Orthic Arenosols Quartzipsamment, and Washed Sand. The bioavailability of saflufenacil is affected by soil properties and therefore the soil type should be considered when deciding upon possible rates.
