초록

Some of the remarkable accomplishments mentioned in the special lecture recalling 38 years of my research on the development of herbicides can be summarized as follows; 1) The physiology, movement in the soil, and decomposition and/or inactivation of the phenoxy and other herbicides by the invention of the Raphanus test were elucidated. And these findings led to the establishment of the theory of herbicidal treatment layer with the result of the origination of the application of PCP in flooded lowland paddy, which opened new era of soil application of herbicides in lowland paddy. 2) The granulation of herbicides for lowland paddy including PCP urea was developed. 3) The fact that propanil has generic selectivity in gramineae was found. And propanil was distributed in rice growing regions of the world. In addition, satanil for upland and propanil/NAC for flooded lowland paddy, propanil mixtures, were developed. 4) 15 kinds of new herbicides derived from plant hormones developed in my laboratory were develop ed, and the research trends in the future were presented.
