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.

Extracts of the unripe fruit of as a potential chemical control against the golden apple snail (Gastropoda, Ampullariidae).

Plant extracts can provide a viable alternative to controlling many crop pests. This study sought to assess the efficacy of vegetable extracts of the unripe fruits of (yerba maté) for chemical control of the channeled apple snail () and of non-target species as the South American catfish () under laboratory conditions. In , the LC of the decoction extract was 31.
