Treatment and prevention of systemic bacterial infections in plants using antimicrobial metal compositions
First Claim
1. A method for treating plants comprising introduction of or exposure to a therapeutically effective amount of one or more antimicrobial metals to treat or prevent an infection by systemic bacterial plant pathogens wherein the one or more antimicrobial metals in contact with plant tissue, or introduced as a solid or fluid, releases atoms, ions, molecules, or clusters wherein at least one antimicrobial metal is silver and wherein the treatment is at a concentration sufficient to inhibit growth of the microorganism.

Abstract
An embodiment of the invention is a treatment for the mitigation and prevention of systemic infection of plants using materials derived from bactericidal metals wherein one metal is silver. The candidate bactericidal metal is preferably introduced in metallic, nanocrystalline, salt form, chelated form, or otherwise coupled form. Metal atoms, ions, molecules, clusters, or particles in concentrations between 0.001 to 100,000 parts per million (ppm) may be employed, wherein the preferred concentration of silver is sufficient to suppress bacterial viability. The bactericidal principle is preferably introduced to the plant by injection, ballistic insertion, pneumatic insertion, mechanical insertion, manual insertion, root application, aerosolization or spray in order to effect the treatment and prevention of systemic plant infections by bacterial agents of disease or reduced productivity.
