Allelopathy has a potential in integrated weed management as a weed control strategy. Crop plants generally have the capability to exude allelochemicals into their surroundings, which can suppress the growth of weeds in their vicinity. In this paper extentive discussions were made on the agents of allelopathic activity and major research activities of allelopathic effects of rice in Japan, A series of experiments on selection for superior genotypes with allelopathic potential have been carried out with several rice cultivars or germplasms. Approaches to crop production that successfully reduce weed seed production can make farmers benefit by reducing management inputs and costs. Japanese allelopathy research team established a new testing method for the allelopathy potential in rice with the combination of biological test and field test. Among them, monochoria test was found to be most valuable for rice allelopathy test. Some old native rice cultivars of Pakistan, Philippines, and India were found to show high allelopathic potential than new cultivars of America and Japan. Upto date, although progress has been made in understanding the genetics of allelopathic activity of crop and successful genetic manipulation, further researches are required for a full degree of understanding of the genetic control of allelopathic activity in rice. Once the allelopathic genes are identified, a breeding program could be initiated to transfer the genes into modern cultivars and enhance their allelopathic activity in order to maximize weed suppression effects. Allelopathic research in rice should be cooperated with the research team of crop ecologists, soil scientists, agronomists, biochemists. plant physiologist, and farmers. This interest can be extended to effectiveness of cover crops, which is able to evaluate the allelopathy potential in the paddy field.
