<p>A method and agents for the control of fungal and bacterial diseases are provided. In one embodiment, specific chelates of one or more metal ions operate to control bacterial caused diseases in plants. In another embodiment, fungal disease in plants is controlled by employing a chelate of zinc ion, together with a chelate of another metal. Some of the metals preferred for use in combination with zinc comprise copper and/or manganese. Some preferred chelating agents comprise glycine, citric acid or resorcinol. The chelates may be based upon organic acids, organic alcohols or amines, aromatic ring substitution products, or other synthetic chelating agents combined with a metal.</p> |
