Ultra low volume formulations of endosulfan (6,7,8,9,10,10-hexachloro-1,5,5a,6,9,9a-hexahydro-6,9-methano-2,4,3-benzodioxathiepine-3-oxide), comprising endosulfan, a mixture of a vegetable oil and aromatic hydrocarbons, and an epoxide stabilizer.
摘要:
An evaporation inhibitor, having particular use with spray mixtures of agricultural chemicals applied by the low-volume method, in the form of a paraffin-containing aqueous dispersion or a self-emulsifying solution in an organic solvent, and having the following composition:______________________________________ from 15 to 40% by weight of paraffin waxes or a wax mixture containing paraffin waxes having a dropping point of from 35 to 80.degree. C., from 4 to 20% by weight of nonionic and/or anionic emulsifiers, from 35 to 81% by weight of water and/or an organic solvent which is one or more of a hydrocarbon, an ester and a ketone, which have boiling points of from 70 to 280.degree. C., and from 0 to 5.5% by weight of other auxiliaries. ______________________________________
摘要:
Processes for the preparation of nitrosamine-free N,N-disubstituted nitroaromatic amines by degradation of their nitrosamine components formed during their preparation, and by stabilization of the products against renewed formation of nitrosamines, by treating the amines in liquid or molten form with a sulfonic acid, where necessary in the presence of inert organic solvents or diluents.
摘要:
Encapsulated salts of organic or inorganic acid particles having sparing solubility in water wherein the salt particles are surrounded by a pressure-resistant, elastic, abrasion-resistant polyurethane/polyurea casing, the ratio by weight of salt to the polyurethane component of the casing material being 1:0.2 to 1:2.5, are produced by emulsifying a mixture of 83 to 28% by weight of the salt to be encapsulated and 17 to 72% by weight of a polyurethane prepolymer containing free isocyanate groups in water in the presence of a protective colloid and reacting the emulsified prepolymer with the equivalent amount of polyamine at temperatures from 0.degree. to 80.degree. C., with vigorous mixing.

摘要:
Liquid, herbicidal compositions containing Linuron as active substance in the form of emulsifiable concentrates or of aqueous suspension concentrates contain as crystallization inhibiting substance 0.05 to 2% by weight of fat-soluble disazo dyes which prevent the active substance from crystallizing in the aqueous emulsions of the emulsifiable concentrates and in the aqueous suspension concentrates and the aqueous dilutions thereof.
摘要:
Dispersions of 2-methyl-5,6-dihydropyran-3-carboxylic acid anilide and benzimidazole-2-carbamic acid methyl ester or 1-n-butylcarbamoyl-benzimidazole-2-carbamic acid methyl ester in paraffinic mineral oils, liquid triglycerides and/or liquid esters of C.sub.1 to C.sub.12 monoalcohols have a synergistic effect against rust and other fungus diseases. The dispersions are stabilized against crystal growth by adding aluminum chelates of certain hydroxy-quinones, e.g., alizarin.
摘要:
Salts of benzimidazole-carbamic acid esters with certain organic sulfonic and sulfuric acid esters are substantially insoluble in water and soluble in organic solvents. These are valuable fungicides especially suitable for ultra low volume formulations.
