Sixty years has passed since an herbicide for paddy fields was first used in Japan. At that time labor for weed control was 50.6 hours/10a while it is 1.4 h/10a today. This laborsaving can be attributed to the development of new active ingredients resulting in sequential applications, granule formulations and new applicators. Since the 1960s, the formulation has been mainly 3 kg granules with an application rate of 3 kg/10a. With decreasing numbers of farmers, and the increasing age of farmers, laborsaving formulations of flowable, jumbogranule and 1 kg granule were developed. However, this control is in the paddy field where the rice is growing. But some problems remain, such as new weeds in upland-paddy rotations and weed control in levees. These problems should be solved for further laborsaving.
