| ABSTRACT: The objective of this work was to study the influence of adjuvants on leaching and persistence of sulfentrazone in a Red-Yellow Ultisol. The soil was stored in PVC columns of 10 cm diameter and 50 cm length. The treatments were composed of sulfentrazone mixed with six adjuvants (Adesil®, Break-Thru®, Assist®, Hoefix®, Fera® and Nortox® Vegetable Oil), a treatment with sulfentrazone without any adjuvant and a treatment without the herbicide. In the treatments with sulfentrazone, the herbicide was applied at a rate of 1.0 kg ha-1 at the top of the columns, and 12 hours after application, the columns were subjected to simulated rainfall (60 mm). To confirm leaching of sulfentrazone, soil samples were collected every 5 cm up to 50 cm in each column... |
