The integrated rice and duck farming system,as a comprehensive environmental-friendly planting-breeding technique,is developed from Chinese traditional farming-raising ducks in paddy fields.There exists a mutualism relationship between rice and duck when they grow together in paddy fields.Ducks can take controls on some harmful organisms in the fields.This paper reviewed the effects of rice-duck farming system on rice diseases,pests,weeds and beneficial insects.Based on the study in China,the results showed that the integrated rice-duck farming system can effectively control most weeds,some species of insect pests,and several kinds of diseases of rice.However,it can also take some effects on population of beneficial insects in paddy fields.It also suggested that further studies on the effects and mechanics of raising ducks to control the pests,diseases,weeds and beneficial insects are needed.
