Monitoring and modeling of pesticide fate and transport in agricultural environment
Research members： Hirozumi Watanabe PhD., Takashi Gomi PhD.
Research fields： Environmental analyses and evaluation, Plant production and environmental agriculture, Agro-engineering
Departments： Institute of Agriculture
Keywords： Pesticide fate and transport, Environmental pollutants, monitoring, modeling
Summary
The research area focuses on monitoring and modeling of pesticide fate and transport in agricultural environments. The major objectives of the current research activities are development and assessment of the good agricultural practices for reducing the environmental exposure risks associated with pesticide use in agricultural production.
1. Monitoring of pesticide fate and transport
2. Modeling of pesticide fate and transport
3. Current progress and Future aspects
Modeling the behavior of nursery box applied rice pesticide has been in progress and application of the model to investigate local management and long term effects are in progress.
In order to simulate pesticide behavior in watershed having both upland and rice paddy, PCPF-1 model is being incorporated in to SWAT model, basin scale hydro-chemical simulation model developed by USDA. The model PCPF-1@SWAT is calibrated for Japanese watershed and will be validated for Sacramento River basin in California.
A plot scale monitoring and modeling study for the pesticide fate and transport in upland field has been in progress. A simple plot scale model (SPEC model) for predicting pesticide residues in Agricultural soil has been developed. A project for monitoring and modeling for pesticide runoff from upland fields using a rainfall simulator has been started recently.
For international cooperation through pesticide monitoring and modeling, the application of the monitoring and modeling procedures developed in the lab to other international sites in Asia, Europe and the US is of our interest.
