چکیده انگلیسی
This study involved the use of terrestrial plant extracts as substitutes for toxic chemicals to control the major fouling organisms of mangroves, the barnacles. In terms of the solvents used to obtain the plant crude extracts, ethyl acetate was best, ethyl alcohol next and pure water worst, except in the case of Allium cepa (AC), where pure water was better than ethyl alcohol. For different plants, different solvents resulted in different poisonous effects, and plants belonging to different classes showed different levels of activities. In particular, using ethyl acetate crude extracts, Allium sativum (AS), AC and Capsicum annuum (CA) caused massive death of barnacle larvae at a low concentration in the shortest time. The less poisonous organic solvents were able to extract more active materials, and this was advantageous in enhancing the effect. For pure water crude extracts, AC and Zingiber officinale were best, but for 95% ethyl alcohol crude extracts, AS and AC were best. For ethyl acetate crude extracts, the effects of AS, AC and CA were better. Different solvent extracts of AC with 12Â h of exposure all had LC50 values <100Â mg/L. The concentrations of the effective plant crude extracts used were close to, or even lower than, those used for pesticides referred to in the literature.
