Nine isolates of pathogenic aquatic fungi: Aphanomyces piscicida NJM 9510, Aphanomyces astaci FDL 445, Aphanomyces sp. NJM 9406, Aphanomyces sp. NJM 9623, Saprolegnia diclina NJM 9219, Achlya sp. E. MCF 1-02, Achlya sp. T. MCF 1-02, Achlya bisexualis NJM 0611 and Achlya sp.
NE 08, were tested for their sensitivity to four chemicals: sodium chloride, hydrogen peroxide, acetic acid and povidone iodine. Hyphal agents at the edge of the growing colonies were cut and immersed in various concentrations of the four chemicals for 60 min and then placed on glucose yeast extract agar. The results showed that the diameter of the fungal colonies increased when the chemical concentrations were decreased. The minimal inhibitory concentrations (MIC) of the nine isolates were: 5.00, 0.38, 0.75 and 0.31% for sodium chloride, hydrogen peroxide, acetic acid and povidone iodine, respectively. For the same four chemicals, the fungicidal concentrations of the nine isolates were: 20, 0.75, 1.60 and 0.63%, respectively.
