“…After 24 h, aqueous extracts of wild beets and oleander exhibited the most significant percentage mortality of 90 -100%, whereas Jimpson weed showed 70% mortality (Kassem et al, 1993), as well as Olofintiye et al (2011) found larvae mosquito mortality rate under 50%, but at 100% concentration, it reached 100%. Additionally, Baleta et al (2015) observed it was toxicity more pronounced in small golden apple snails than large snails. Also, the boiling water extract for the leaf of Datura stramonium has phenolic compounds that cause 57.5% repulsion for insects (Amira et al, 2020).…”

Land snails (Monacha obstructa) are commonly found in a variety of plant species, making them an important target for this study. Therefore, the opjective of this study is to compare eleven plant extracts and select the most efficient one to evaluate the acute toxicity of their extracts using the contact method against Monacha obstructa. The findings revealed that the plant extracts with the highest effectiveness against land snails were chinaberry (Melia azedarach), apple of Sodom (Calotropis procera), Nerium (Nerium oleander), and Basil (Ocimum basilicum) leaf extract. Consequently, the results indicated that the aqueous extracts from the leaves of M. azedarach exhibited high toxicity, with an LC50 value of 11.88 mg/L and a 100% mortality rate. Following that, C. procera leaves had an LC50 value of 16.82 mg/L and a mortality rate of 70.61%. The aqueous extracts from N. oleander (flowers and leaves) displayed a moderate mortality rate of 58.06% and 56.96% with LC50 values of 20.46 mg/L and 20.85 mg/L, respectively. The decoction of the leaves of the plants with O. basilicum leaf extract had the lowest death rate for individuals after 24 h which was 45.90%, and the toxicity rate for land snails was recorded at 25.88 mg/L. However, the rate of death of treated snails were decreased compared to that of control ones. These findings suggest the potential recommendation of utilizing a decoction of the extracted plants as an alternative to expensive and environmentally harmful pesticides for controlling clover snails.
