Abstract: [Problem] To provide an antibacterial agent which can be limited to the required location on the surface of a material without mixing and has excellent antibacterial, antifungal and antiviral effects even at low concentrations of the active component without elution or volatilization. [Solution] An antibacterial agent that contains as an active component a resin having an organic group represented by general formula (I-1). (In the formula (I-1), R1 and R2 mutually independently represent a C1-C4 fluoroalkyl group. “C” and “A” are bonded to each other through a covalent bond or an ionic bond, and “A” represents a hydrogen atom or a cation.

Abstract: The invention relates to a coated granular fertilizer having a film covering fertilizer granules. This film comprises a polyurethane resin prepared by a method comprising the steps of (a) reacting an aromatic polyisocyanate with a first polyol component (i.e., castor oil or a castor oil derivative), thereby to obtain a prepolymer having terminal isocyanate groups in the molecule; and (b) reacting the prepolymer with a second polyol component (i.e., castor oil or a castor oil derivative) and a third polyol component which is an amine having at least two hydroxyl groups in the molecule, thereby to cure the prepolymer and thus to prepare the polyurethane resin. The invention relates to another coated granular fertilizer having a film covering fertilizer granules. This film comprises a urethane resin and aqueous-fluid-absorbing particles having a particle diameter of from 1 to 200 &mgr;m. This urethane resin may be the above polyurethane resin.

Abstract: A microbial pesticide containing a living Erwinia carotovora subsp. carotovora, particularly, the Erwinia cartovora subsp. carotovora CGE234M403 strain, from which the pathogenicity of soft rot is deleted by mutagenesis and which is immobilized by mixing with a saccharide such as saccharose, glucose, fructose or sorbitol or beef extract and drying or freeze-drying the mixture under reduced pressure, as an active ingredient is applied to soil or plants, which are liable to suffer from soft rot, bacterial seedling blight of rice and black rot, in the form of a suspension, granules or powder to control the diseases.
