摘要： A flucarbazone sodium hemihydrate method and composition. A method of suppressing growth of grass and broadleaf weeds is described including applying to said weeds at least one dust-free composition comprising flucarbazone sodium-hemihydrate as an active ingredient. A method for preparing flucarbazone sodium-hemihydrate is also described including treating 4,5-dihydro-3-methoxy-4-methyl-5-oxo-N-[[2-(trifluoromethoxy)phenyl]sulfonyl]-1H-1,2,4-triazole-1-carboxamide (MSU) with aqueous sodium hydroxide under pH-controlled conditions; and confirming that a hemihydrate flucarbazone sodium of the following formula: has been obtained.

摘要： A method of controlling anthracnose caused by Colletotrichum on tropical fruits, tropical fruit plants or cultivars or plant parts or locus thereof is described. The method comprises the steps of contacting the tropical fruit plant or cultivar in need of treatment with an agrochemical composition comprising an effective amount of a guanidine or a salt and/or solvate thereof. The contacting step may be repeated one or more times at a fixed interval. The guanidine may be dodine, iminoctadine trialbesilate, iminoctadine triacetate, guazatine, salts and/or solvates of any of the foregoing and combinations of one or more of the foregoing.

摘要： An herbicidal composition and method. An oil dispersion is described including one or more base oils; an herbicide composition comprising an herbicide composition comprising a triazolinone, a 4-hydroxyphenylpyruvate dioxygenase inhibitor, and a sulfonylurea; and a stabilizer comprising a phosphoric acid and/or a phosphoric acid derivative, and/or a mixture of phosphoric acid and/or phosphoric acid derivative with urea and/or a urea derivative; the dispersion demonstrating an enhanced spectrum of weed control and enhanced stability. A method of preparing an herbicidal composition and a method of controlling weeds are also described.

摘要： Preparation of O,O-dimethyl phosphoramidothioate and O,O-dimethyl phosphoroamidothioate. A process of making O,O-dimethyl phosphoroamidothioate is described including reacting sulfur with PCl3 to form PSCl3, reacting the PSCl3 formed with methanol to form O-methyl phosphorodichloridothioate, and reacting the O-methyl phosphorodichloridothioate formed with methyl lye to form O,O-dimethyl phosphorochloridothioate in solution in CH2Cl2, and reacting the O,O-dimethyl phosphorochloridothioate formed with sodium hydroxide and ammonium hydroxide to form O,O-dimethyl phosphoroamidothioate in solution in CH2Cl2. Reacting the O,O-dimethyl phosphoroamidothioate formed with catalytic dimethyl sulfate to form methamidophos and reacting the methamidophos formed with acetic anhydride to form N-(methoxy-methylsulfanylphosphoryl) acetamide is also described. Throughout the process, the O,O-dimethyl phosphorochloridothioate and the O,O-dimethyl phosphoroamidothioate formed are maintained in solution in CH2Cl2 at all times.
