                                    Citation: Schrader, K. 2005. Evaluation of several commercial algicides for control of odor-producing cyanobacteria. Journal of Aquatic Plant Management. 43: 100-102.Interpretive Summary: A rapid bioassay was used to evaluate several commercial algicides for their toxicity towards several undesirable species of blue-green algae.  One type of blue-green algae cyanobacteria included in the study produces a compound that causes musty off-flavor in farm-raised catfish.  The two commercial products containing barley straw extracts were not toxic towards any of the algae tested.  Another commercial algicide containing hydrogen dioxide was selectively toxic towards the undesirable cyanobacteria.
                                Technical Abstract: A rapid bioassay was used to evaluate several commercial algicides for their toxicity towards several noxious species of cyanobacteria (blue-green algae).  Included in the study was the cyanobacterium Oscillatoria perornata which produces 2-methylisoborneol (MIB), a metabolite that causes musty off-flavor in farm-raised catfish.  The two commercial products containing barley straw extracts were not toxic towards any of the cyanobacteria or the green alga tested.  Another commercial algicide, ZeroTol, that contains hydrogen dioxide was selectively toxic towards O. perornata, Oscillatoria agardhii, and a Pseudanabaena sp. that also produces MIB.  ZeroTol appears to be the most promising of the commercial products evaluated in this study for managing odor-producing cyanobacteria.
