Abstract:
PROBLEM TO BE SOLVED: To provide a method for improving storage stability of an algaecidal virus against red tide, in order to prevent reduction in algaecidal ability to algae to be infection object, since a large-sized DNA virus having algaecidal activity against red tide-causing algae is readily deactivated by light and a water temperature, although activity is kept to some extent by preservation under light shielding and low-temperature conditions and in order to further improve preservability, wherein antibiotics and glycerol as a protecting agent are added to the algaecidal virus against red tide. SOLUTION: The method for improving storage stability of the virus comprises adding streptomycin sulfate (50-5,000 ppm) and chloramphenicol (5-500 ppm) and glycerol (1-20%) to a suspension of HaV (Heterosigma akashiwo virus) being an algaecidal virus against Heterosigma akashiwo of harmful red tide-causing alga and HcV (Heterocapsa circularisquama virus) being an algaecidal virus against Heterocapsa circularisquama.

Abstract:
PROBLEM TO BE SOLVED: To obtain the subject composition capable of surely controlling major paddy field weeds with a small amount of the composition, for a long time by single application and causing no injury against paddy rice by using a substituted benzoyl cyclic enone derivative with another compound having herbicidal activity in combination. SOLUTION: This composition is obtained by compounding a substituted benzoyl cyclic enone derivative of formula I A is S(O)n R [R is an alkyl, a cycloalkyl, benzyl, etc.; (n)=0, 2], etc.} with a halogen-substituted benzoyl pyrazole derivative having herbicidal activity. As the halogen-substituted benzoyl pyrazole derivative, a compound having herbicidal activity of formula II [R is H or an alkyl; R and R are each an alkyl; R is H or an alkyl; Y is a sulfonyl, or a carbonyl; (m) is 0-3] is preferable. As the compound of formula II, 4-(2,4-dichlorobenzoyl-1,3-dimethyl1H-pyrazol-5-yl-p-toluenesulfonate, etc., is especially preferable. The composition can be applied in a wide season from before the occurrence to the growth of weeds.
Abstract:
PROBLEM TO BE SOLVED: To provide a method for efficiently producing methylene norcamphor under mild conditions. SOLUTION: The method for producing methylene norcamphor comprises (A) carrying out a reaction between formaldehyde and norcamphor under heating at ≥60°C in the presence of a secondary amine and an organic acid, or (B) carrying out a reaction between an aqueous formaldehyde solution( formalin ) and norcamphor under heating at ≥60°C in the presence of a secondary amine and an organic acid. In this method, (1) prior to or during the reaction under heating, an extraction solvent for the methylene norcamphor is added, or (2) after the reaction under heating, the extraction solvent for the methylene norcamphor is added followed by heating to ≥60°C.

Abstract:
PROBLEM TO BE SOLVED: To provide a decay diagnosing method capable of diagnosing the decay of wood simply and certainly from a decay initial stage, and a decay diagnosing agent used therein. SOLUTION: In this decay diagnosing method of wood, the decay diagnosing agent containing an antibody, which is obtained by sensitizing an animal using protein with a molecular weight of 1,000-100,000 obtained by culturing wood decaying bacteria naturally present in Japan as an antigen, is brought into contact with an extract obtained from wood to be tested to decide the decay of the wood to be tested. The decay diagnosing agent is also disclosed. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To obtain a herbicide composition exhibiting synergistic effects between herbicidal activities of active ingredients, having a wide weeding spectrum, exhibiting excellent herbicidal effects by a small amount, and sufficiently safe to some important crops such as wheat, barley, corn, soybean and cotton. SOLUTION: The herbicide composition contains one or more kinds of substituted pyrazole derivatives represented by formula (I), and one or more kinds selected from a dinitroaniline-based compound, a urea-based compound, an amide-based compound, a carbamate-based compound, a diphenyl ether-based compound and a sulfonylurea-based compound as the active ingredients.
