摘要： The invention relates to a method of producing aqueous suspensions of copper hydroxosulphates, such as brochantite, antlerite or a mixture thereof, having a high copper weight content. The inventive method consists in reacting an aqueous solution of copper sulphate with an aqueous suspension of copper oxide or copper hydroxide having an average solid particle diameter of less than 25 µm. The invention also relates to the preparation of copper fungicidal compositions with a copper content of up to 45 %, in the form of powders, granules or concentrated suspensions which can be dispersed in water. The invention further relates to the use of said compositions for the fungicidal treatment of cultures.

摘要： The invention relates to a method for production of microbeads of a pesticide, which is at least partly soluble in water, by polycondensation of complementary organic reagents R1 and R2 in a biphasic liquid system, whereby the reagent(s) R1 is(are) placed with the pesticide in a polar liquid phase (Fp) and the reagent(s) R2 is(are) placed in an oily liquid phase (Fh), comprising a solvent (S) which is immiscible with the polar phase and at least one detergent which permits the dispersion with agitation of the polar phase (Fp) in said oily phase (Fh), characterised in that the combination of reagents R1 and R2 is selected such that the polycondensation occurs in the polar liquid phase (Fp).
