| Research Abstract |
Ecological risk management of pesticides in Japan is conducted based on the results of risk assessment, but the uncertainty of this prediction has been pointed out. To improve the assessment reliability, adaptive management should be applied to pesticide management. Therefore, this study conducted multi-point monitoring of aquatic plants and rice herbicides in agricultural drainages around paddy fields, and demonstrated the possibility to identify the ecological impact of an herbicide using the field monitoring data. Moreover, we showed the combination of large-scale modeling of pesticide dynamics and monitoring survey was useful to achieve adaptive management of pesticides.
