Embryos of Danio rerio are highly susceptible to extracts of the plants Tephrosia vogelii and Asystasia vogeliana. The concentration of the dried extracts at which 50% of the embryos were affected (EC50) after 24 h exposure were 320 and 572 μg l−1, respectively; corresponding 50% mortality (LC50) values after 48 h exposure were 493 and 869 μg l−1. Results indicate that the use of these ichthyotoxic plants might have a severe impact on the survival of fish larvae in the field.
