  • Plant-protection treatment of plants and compositions which can be used for this purpose
    Patent number: 6562757
    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.
