摘要:
A herbicide composition including an oily extract as an active ingredient, which oily extract is obtained by cooling a steam containing volatile substances in a drying step of a lumber of trees belonging to the order Pinales, or by subjecting wood chips, sawdust or wood powder to hot water extraction or steam distillation.
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 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.
摘要:
The present invention relates to an inhibitor for tobacco axillary bud growth, the inhibitor comprising one or more cell division inhibitors selected from the group consisting of pyridine-based compounds and benzamide-based compounds. This inhibitor for tobacco axillary bud growth has excellent sustainability of effect at low concentration, does not cause chemical damage and disease, and can ensure an improvement in labor productivity. An aliphatic alcohol having 6 to 20 carbon atoms is furthermore combined with the cell division inhibitors selected from pyridine-based compounds and benzamide-based compounds to thereby synergistically enhance the effect of inhibiting the emergence and growth of tobacco axillary buds.
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:
An inhibitor for tobacco axillary bud growth, the inhibitor containing one or more cell division inhibitors selected from pyridine-based compounds and benzamide-based compounds. This inhibitor may further include an aliphatic alcohol having 6 to 20 carbon atoms in combination with the one or more cell division inhibitors.
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.
