Recently, problems involving the pollution of water sources with pesticides used at golf courses have surfaced. We will report on the removal of some representative pesticides which are often detected and widely used at golf courses using the absorption qualities of mung bean roots. We were able to efficiently remove these pesticides in a short time, even a very low concentration. For standards of wastewater from golf courses, we obtained a high removal efficiency of 87 to 100% by a short time treatment (16 hours) with the insecticides fenitrothion, chloropyrifos, fungicides isoprothiolane, and chlorothalonil. The absorption efficiency for insecticide diazinon and fungicide captan was slow, however, 94% and 59% was removed, respectively, in a 2 day period. We assumed that the absorbed pesticides accumulated in high concentrations inside the body of the mung beans not influenced to their growth except chlorothalonil and simazine. This is shown by the result of the absorption of nutrients and the dry weight.
