This invention is to provide microbial pesticides that can control plant disease damages by spraying the microbial pesticides, which contain filamentous fungus Verticillium lecanii having suppressant effect on the growth of plant pathogen, onto plants such as fruits and vegetables, and to provide soil borne improvement agents which contain filamentous fungus Verticillium lecanii, and exert effect on improving the soil borne by applying to soil borne. By applying filamentous fungus Verticillium lecanii, preferably strains having an ability of colonization on plant surface, and/or strains having an ability of colonization on plant root surfaces and/or in rhizosphere to plants as microbial pesticides, the growth of plant pathogens as well as insect pests adhering to plants can be significantly suppressed. Furthermore, by giving them to soil borne, the growth of pathogens in plant rhizomes and the rhizosphere thereof can be suppressed, and pathogens are not developed in the soil borne even after the transplantation, therefore, the soil borne can be improved.

A door includes an inner panel, an outer panel, a door beam fixed to the inner panel, hinges, and a door lock unit. The door beam is connected at one end to one end side face of the inner panel at a first location and at the other end thereof to the other end side face at a second location higher or lower than the first location along a substantial diagonal of the outer panel. A first vibration damping member intervenes between the door beam and the outer panel to have contact with the door beam and the outer panel. A second vibration damping member may be further arranged above or under the door beam inside the outer panel. A third vibration damping member including a patch member may be attached to an interior face of the outer panel.

The present invention relates to a process for producing improved water-absorbent resin particles comprising the step of treating water-absorbent particles, which are crosslinked polymers of ethylenically unsaturated monomers comprising acrylic acid and/or acrylic acid salt as an essential element, with a modified silicone oil having a functional group which can react with a carboxyl group and/or a carboxylate group in the molecule Improved water-absorbent resin particles obtained by the process have a hygroscopic blocking rate of 20 % or less under a relative humidity of 80 % at 40.degree. C., a dust level of 10 CPM or less and an absorbing characteristic of initial absorbency under load to physiological saline of 20 times or more. The present invention provides water-absorbent resin particles which have an improved hygroscopic blocking rate under high humidity and dust generation rate with a good initial absorbency under load and absorbing capacity.
