Ecotoxicological evaluation of fruit extracts from yerba mate progenies ( a St-Hil.): a natural biopesticide.

This study evaluated the biocidal activity of aqueous fruit extracts from progenies at different ripening stages in two ecotoxicity assays using juveniles and larvae. Mutagenicity was verified by the /microsome assay (TA 98 and TA 100) in the presence and absence of hepatic metabolism in vitro. The results showed that the snails were more sensitive than the larvae to the P.
