OILY SUSPENDED FORMULATION FOR DIRECTLY APPLYING TO WATER SURFACE

PURPOSE:To obtain a suspended formulation containing 2',3'-dichloro-4-ethoxy methoxy benzanilide as an active ingredient of weeding agent, mineral oil or vegetable oil as a dispersing medium and a nonionic surfactant or an anionic surfactant having a specific HLB value. CONSTITUTION:The subject formulation contains 5-40wt.% 2',3'-dichloro-4-ethoxy methoxy benzanilide, mineral oil (e.g. paraffin oil) or vegetable oil (e.g. soybean oil) as a dispersing agent and a nonionic surfactant or an anionic surfactant (e.g. fatty acid ester of sorbitan). Said formulation exhibits an weeding effect with quick diffusion on water surface and uniform dispersion of the agent into the water by directly spraying to water surface of a paddy field filled with water without diluting in a large amount of water nor using any spraying device, etc. The active ingredient is crushed to 20-50mum by a dry crusher and mixed with a dispersing medium and a surfactant, then subjected to a pulverizing treatment by a wet pulverizer to afford the aimed formulation.
