Rice-duck farming system is one of the means of organic rice farming, in which the weeds, diseases and
insects could be effectively controlled with minimal or no pesticide and herbicide application. Whereas in
conventional rice-duck farming system the controlling effect on diseases, insect pests and weeds was slowly
disappeared after the rice heading stage at which ducks were driven out of the paddy field. To fill up the blank
period of pasture activities of ducks, this study put forward two new rice-duck farming systems innovated from the
conventional rice-duck farming system, in these new systems, two batches of ducks were raised with rice within one
rice planting season. The results revealed that the overall controlling effect of ducks on rice diseases, insect pest and
weeds was significantly enhanced in the two new rice-duck farming systems without agrochemicals application. It
might be suggested that these two new systems have potential application as biocontrol agent for the organic rice
agriculture.
Key words: Biocontrol, disease, insect, pest, rice, two batch of duck-rice system, weeds
