  • Method of producing copper hydroxosulphates and copper fungicidal compositions containing same
    Patent number: 8911794
    Abstract: The subject of the invention is a process for the manufacture of aqueous suspensions of copper hydroxosulphates such as brochantite or antlerite, or a mixture of both, having a high copper content by weight, by reacting an aqueous solution of copper sulphate with an aqueous suspension of copper oxide or copper hydroxide in which the mean diameter of the solid particles is less than 25 ?m. The invention also relates to the preparation of cupric fungicidal compositions having a copper content which may be as high as 45%, in the form of powders, granules or suspension concentrates, dispersible in water, and their use for the fungicidal treatment of crops.
    Type: Grant
    Filed: April 14, 2004
    Date of Patent: December 16, 2014
    Assignee: Cerexagri
    Inventors: Frederic Ferrier, Gerard Joncheray, Marc Pillot

  • Production of microbeads of pesticides and use of said microbeads for the protection of crops
    Publication number: 20060148652
    Abstract: Process for the manufacture of microbeads of an at least partially water-soluble pesticide by polycondensation of complementary organic reagents R1 and R2 in a liquid two-phase system, the reagent(s) R1 being placed with the pesticide in a polar liquid phase (?p) and the reagent(s) R2 being placed in an oily liquid phase (?o) comprising a solvent (S) that is immiscible with the polar phase and at least one surfactant for dispersing the polar phase (?p) in the said oily phase (?o) with stirring, characterized in that the pair of reagents R1 and R2 is chosen in such a way that the polycondensation occurs in the polar liquid phase (?p).

  • Plant-protection treatment of plant and compositions which can be used for this purpose
    Publication number: 20030157189
    Abstract: To increase the effectiveness of a cupric plant-protection composition and therefore to reduce the dose of copper used per hectare, a copper source, in non-chelated form, is combined with a sparingly soluble calcium and/or zinc and/or manganese chelate. This combination makes it possible to obtain, in situ, the gradual release of a soluble copper chelate.
