  • Agricultural chemicals composition, preparation thereof and the method for scattering the same
    Patent number: 6703350
    Abstract: In an agricultural chemicals composition which is scattered by being thrown directly into a submerged paddy field, it is an object to provide a composition having an excellent spreadability without stagnation of an agrochemically active ingredient at the point of treatment (application), and in particular to provide a labor-saving formulation for scattering (application) which contains a liquid agrochemically active ingredient at room temperature, and to provide an agricultural chemicals composition containing a liquid agrochemically active ingredient at room temperature in high concentrations, which have been difficult to be realized.
    Type: Grant
    Filed: November 16, 2001
    Date of Patent: March 9, 2004
    Assignee: Kumiai Chemical Industry Co., Ltd.
    Inventors: Shigeki Fujita, Tohru Takayanagi, Susumu Kato
  • Agricultural chemicals formulation for rice paddy field, preparation thereof and the method for scattering the same
    Patent number: 6486095
    Abstract: In an agricultural chemicals formulation which is scattered by being thrown directly into a paddy field filled with water, it is an object to provide a composition having an excellent spreadability without stagnation of an agrochemically active ingredient at the point of throwing, and in particular to provide a labor-saving formulation for scattering (application) which contains a liquid agrochemically active ingredient at room temperature, and to provide an agricultural chemicals formulation containing a liquid agrochemically active ingredient at room temperature in high concentrations, which have been difficult to be realized. The agricultural chemicals formulation for a rice paddy field is produced by preparing a granular composition in a manner that a mixture of a liquid agrochemically active ingredient at room temperature, a surfactant, and a substance exhibiting a thickening function or a gelation function in the water, is held and carried by a granular nucleus, and packing it with a water-soluble film.
