Abstract: The agricultural non-point source pollution is the largest one of total non-point source pollution in China, while water pollution is the most important part. “Prevention” is better than “treatment” for preventing and controlling the agricultural water pollution due to its complexity. With the rapid development of science and technology in recent years, microbial technologies play a more and more important role in the prevention and control measures for the water pollution in agriculture. Applying microbial technologies could reduce the pollutants discharge into the receiving water by reducing the agricultural source pollution and intercepting the agricultural process pollution, therefore it is beneficial to the sustainable development of agricultural ecological environment. In this paper we review and prospect the applications of microbial technologies in the prevention and control of agricultural non-point source pollution, including “source reduction” and “process interception”, which is expected to provide the valuable reference for the control of agricultural non-point source pollution.

Key words: microorganism, water pollution, agriculture, non-point source pollution
