摘要:
A method for treating wood, characterized by impregnating wood with a metal-containing treating agent containing lignin and/or lignin derivatives and a metal, a metal compound, and/or a metal ion and oxidizing and/or macromolecularizing of the lignin and/or lignin derivatives in the wood to fix the metal component in the wood, and wood and woody materials obtained by the treating method. According to the method of the present invention, while effectively utilizing lignins, lignosulfonic acids, or lignosulfonic acid salts, leaching of the metal component can be suppressed to a low level to thereby retain the effects due to the incorporation of the metal components for a prolonged period.
摘要:
The invention provides a simple method which enables precise diagnosis of wood decay at an early stage of decay and an agent used for the diagnosis method. The invention provides a method for diagnosing wood decay, wherein wood decay is judged by contacting extract of wood to be examined (test subject wood) with an antibody obtained by sensitizing an animal to an antigen which is a protein having a molecular weight of 1,000 to 100,000 obtained by culturing a naturally occurring wood-destroying fungus and an agent for the diagnosis method.
摘要:
A method for preparing dimethylolcarboxylic acid derivatives represented by general formula (1) ##STR1## (wherein R is a hydrogen atom, an amino group, an alkyl group, or an alkyl group having a hydroxyl group) to react with a culture broth, cells or a processed cell product of a microorganism belonging to the genus Rhodococcus or Agrobacterium having an ability to oxidize a methylol group of the tris(hydroxymethyl) derivative represented by general formula (2) ##STR2## wherein R has the same meaning as defined above. According to this invention, dimethylolcarboxylic acid derivatives can be produced efficiently under mild conditions by using microorganisms belonging to the genus Rhodococcus or Agrobacterium and having an ability to oxidize tris(hydroxy-methyl) derivatives to produce dimethylolcarboxylic acid derivatives.
摘要:
The present invention relates to a plant disease control agent containing a compound represented by the following formula (1) or salt thereof as an active ingredient (in the formula, R1 and R2 represents a hydrogen atom or methyl group but excepting cases where R1 and R2 are the same), a plant disease controlling method applying the plant disease control agent on plants suffering from diseases, and a novel compound represented by formula (1) or salt thereof.
摘要:
The present invention relates to an inhibitor for tobacco axillary bud growth, the inhibitor comprising, as an active ingredient, one or more kinds of very-long chain fatty acid synthesis inhibitors such as a chloroacetamide-based herbicide, fentrazamide, cafenstrole or indanofan; an inhibitor for tobacco axillary bud growth, the inhibitor comprising the aforesaid very-long chain fatty acid synthesis inhibitor together with clorthal-dimethyl or an aliphatic alcohol having 6 to 20 carbon atoms; and a method for inhibiting tobacco axillary bud growth which comprises applying the inhibitor for tobacco axillary bud growth. The inhibitor for tobacco axillary bud growth of the present invention shows sustained drug efficacy at a low concentration, induces neither chemical injury nor disease, and can contribute to the improvement in labor productivity.
摘要:
The present invention relates to a wood preservative containing as an active ingredient 3′-isopropyl-2-trifluoromethyl benzoic acid anilide represented by the formula below and a wood treatment method using the same. The present invention can provide a wood preservative having excellent preservation effect on various wood-destroying fungi with a very small chemical dosage and a wood treatment method, which are economical and have a small environmental load.
摘要:
The present invention relates to the Bacillus sp. strains AT-332 (NITE BP-1095) and AT-79 (NITE BP-1094) isolated from nature; and a plant disease control agent, a nematode control agent and a plant growth promoter containing the strains as active bacteria. The Bacillus sp. strains AT-332 and AT-79 strain are effective in controlling both a wide range of various plant diseases and nematode-damage and capable of promoting the growth of useful plants, due to a culture containing a secondary metabolite of the strains or cultivated and isolated live bacteria of the strains being introduced to a plant body or to the culture soil.
摘要:
The present invention provides an antiseptic composition for engineering wood production, which contains epoxyconazole and a thermosetting resin, and engineering wood which is obtained using the antiseptic composition. The antiseptic composition of the present invention enables efficient production of engineering wood such as plywood or laminated veneer lumber (LVL) that has a high antiseptic effect.

摘要:
The present invention relates to a preservative for preserving wood comprising 5-methyl-2-trifluoromethylfuran-3-carboxylic acid anilide derivative represented by the following formula, wherein R represents an iropropyl group or an isopropoxy group as an active ingredient. The preservative for preserving wood has an excellent preservative effect on various wood-decay fungi at an extremely low dose, is economically efficient, and imposes a small burden on the environment. The present invention also relates to a method for treating wood using the preservative.
