  • 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.

  • Bordeaux mixture, process for its manufacture and cupric fungicidal compositions containing it
    Patent number: 5958438
    Abstract: The invention relates to a Bordeaux mixture in which virtually all of the copper is in the form of brochantite and which, in dry form, contains not more than 20% by weight of bassanite.The absence of cupric complexes other than brochantite and a small amount of bassanite in the dry product makes it possible to avoid the drawbacks of standard Bordeaux mixtures.
