We investigated the antifungal activities of linalool, geranyl acetate and 1, 8-cineole, the major essential oils from the rhizomes of the greater galangal <I>Alpinia galanga</I>, against some fungi in the Saprolegniaceae. The toxicity to goldfish (<I>Carassius auratus</I>) and platyfish (<I>Xiphophorus maculates</I>) was also investigated.<I>Saprolegnia parasitica</I> NJM 8604, <I>S. diclina</I> NJM 0236, <I>Achlya bisexualis</I> NJM 9905, <I>A. diffusa</I> NJM 0011, and two isolates (NJM 9701 and NJM 0219) of <I>Aphanomyces piscicida</I> were used in this study. The fungistatic concentrations of linalool, geranyl acetate and 1, 8-cineole against the hyphae of the used strains were 2, 000 to 500, 2, 500 to 250 and 5, 000 to 3, 000 μ g/ml, respectively, while the fungicidal concentrations of each chemical against the strains were 1, 250 to 1, 000, over 2, 000 and 4, 000 to 2, 000 μ g/ml, respectively. The zoospores of all isolates exposed to 750 μ g/ml linalool, 500 μ g/ ml geranyl acetate and 1, 500 μ g/ml 1, 8-cineole for 30 min could not germinate. The chemicals, however, were toxic to platyfish and goldfish at the fungicidal concentrations.
