In order to develop a weed control method for paddy rice by the application of flowable formulations of herbicides, herbicidal efficacies of flowables, wettable powders and granules of chlornitrofen, MK-129 and piributycarb were compared under greenhouse conditions. The results are summarized as follows: 1 . For all the three herbicides tested, the formulation type affected the efficacy of the chemicals as follows: the efficacy decreased in the order of flowables≧wettable powders > granules, and increased with the decrease in the particle size or the chemicals contained in the flowables and wettable powders. 2. Relative mobility and residual activity of the herbicides in soil, and time course of the herbicide concentrations in flooding water were not appreciably affected by the formulation type.
