摘要
The effects of combinations of pesticides (chlorpyrifos, chlorothalonil, fenamiphos) on their degradation rates and on some soil microbial characteristics were studied. There were few interactions between chlorpyrifos and fenamiphos, but the presence of chlorothalonil always resulted in reduced degradation rates of the other compounds. Chlorothalonil also caused a significant reduction in soil microbial biomass and enzyme activities (phosphatase and dehydrogenase).
