Fate of Butachlor and Pyrazosulfuron-ethyl in Rice Paddies under Spring and Summer Crop Seasons

摘要：

The major objective of this research is to investigate the environmental fate of two herbicides, butachlor (BU) and pyrazosulfuron-ethyl (PY) , under spring and summer crop seasons in rice paddy environment. The specific objectives are 1) to monitor the behavior of two herbicides under two different crop seasons in the actual paddy environment, 2) to monitor the behavior of two herbicides in paddy water using MPL with prescribed hydrological conditions under ambient temperature on two crop seasons, 3) to investigate degradation processes of pesticides in paddy water under different temperature and under the condition with and without natural sunlight using batch experiments.
