(57) [Summary] [Object] The present invention provides a herbicidal formulation for water surface application, which has a good diffusibility in water when it is dropped into a paddy field from a container without being diluted with water. [Composition] Consisting of a herbicidal active ingredient, a nonionic surfactant of HLB 10 to 15, a thickener and water, and the specific gravity of the preparation at 25 ° C is 0.95 to 1.05 and the viscosity is 200 to 10 00 centipoise, surface tension at 20 ° C is 35-6 Water-applied herbicidal preparation characterized by having a content of 5 dyne / cm 2 . [Effect] The herbicidal preparation for surface application of the present invention has good storage stability for a long period of time and good diffusion of the herbicidal active ingredient in the paddy water.
