Glyphosate is the most used pesticide in Argentina. H. curvispina is a widely distributed and commonly abundant component of the invertebrate assemblages in shallow waters of southern South America. The aim of this study was to assess the acute toxicity of the increasingly common Roundup Full II ®, commercial formulation of the herbicide glyphosate (66.2% a.i.), to H. curvispina in laboratory and field assessments. The mean estimated 48-h LC50 of Roundup was 9.9 ± 1.7 mg/l. In a field experiment Roundup was applied to soybean plots. Simulated rain was generated the following day by means of irrigation sprinkler equipment. H. curvispina was exposed to runoff water and soy leaves. No mortality was observed. It is suggested that Roundup crop applications represent a low risk of acute toxicity to H. curvispina adults inhabiting water bodies adjacent to crop fields.
