PURPOSE:To control algae in a small amount of chemicals by adding a controlling agent against the algae containing glutaric dialdehyde and 3- cyclohexyl-6-(dimethylamino)-1-methyl-1,3,5-triazine-2,4-(1H,3H)dione to objective river systems. CONSTITUTION:A controlling agent for algae containing glutaric dialdehyde and 3-cyclohexyl-6-(dimethylamino)-1-methyl-1,3,5-triazine-2,4-(1H,3H)dione at (99:1)-(50:50), preferably (95:5)-(70:30) weight ratio. The above-mentioned controlling agent is effective in controlling algae (especially algae of the genus Ulothrix, Hormidium or Microspora) belonging to the suborder Ultrichineae and added in an amount of 1-30mg/l active ingredient to objective river systems. The chemicals used themselves have low or no corrosiveness, irritancy, foaming properties, etc. |
