Abstrakt: | The use of long-residual herbicides can have adverse effects on terrestrial ecosystems. This study assessed the acute and chronic toxicity and avoidance behavior of Eisenia andrei earthworms exposed to nominal concentrations of clomazone, indaziflam, and sulfentrazone, using recommended commercial formulations for sugarcane cultivation. The formulations included Gamit® 360 CS (360 g L -1 of the active ingredient - a.i. - clomazone), Boral® 500 SC (500 g L -1 of a.i. sulfentrazone), and Alion® (500 g L -1 of a.i. indaziflam). Boral® 500 SC induced avoidance at concentrations as low as 1 mg kg -1 , while Gamit® 360 CS and Alion® exhibited higher avoidance at 50-75 mg kg -1 and 75-100 mg a.i. kg -1 , respectively. Reproduction tests showed significant impacts from Gamit® 360 CS (EC Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.
