All across biological system, fungal infection in freshwater systems is well known to obstruct the aquatic biomass population such as microalgae. However, there is a lack of extensive information on the suitable technique to control them. This research aims to assess the effects of the fungicide fluazinam as a single dose treatment on the Haematococcus pluvialis growth rate and the presence of chytrids fungus in a liquid culture system. The variables used in this experiment were the concentration of fluazinam given to the culture (i.e. 0.25; 0.5; 0.75; 1; 1.25 ppm) as a single dose treatment. The growth performance of H. pluvialis was observed in 6 days consecutively based on the cell density by a single direct absorbance measurement and the cell counting by haemocytometer. The best growth was achieved in a culture system which was given fluazinam at a concentration of 0.5 ppm (started from 1.0 x 10 5 cells/mL to 5.5 x 10 5 cells mL −1 on the 5 th day) and no chytrids fungus are found in the culture system either. So, in conclusion, the use of fluazinam is a promising treatment for removing contaminants that inhibit H. pluvialis growth.
