Conclusions:
The toxicity (LC50) of the essential oil of Cymbopogon winterianus towards Biomphalaria glabrata and hatched larvae of Artemia salina is 54 and 181 mg/L respectively.
Executive summary:

The toxicity of the essential oil of Cymbopogon winterianus towards Biomphalaria glabrata and hatched larvae of Artemia salina was investigated by exposing these organisms to concentrations ranging from 10 to 1000 mg/L. The toxicity (LC50) was found to be 54 and 181 mg/L for Biomphalaria glabrata and hatched larvae of Artemia salina respectively.
