Patent ID: 8795736

Claim:
A method of controlling bacterial infection in plants using an inorganic phosphite composition, said method consisting of the steps of: assessing at least one plant for infection of said plant by a bacterial disease; applying said inorganic phosphite composition if said plant is infected by a bacterial disease to said plant infected by a bacterial disease, said inorganic phosphite composition consisting of at least one inorganic phosphite component configured for bactericidal effect and/or a plant defense stimulation effect as an active ingredient, wherein said at least one inorganic phosphite component is selected from the group consisting of inorganic copper phosphite and inorganic nutrient-halo-phosphite, wherein said active ingredient is present in such a concentration that said inorganic phosphite composition is configured to have a plant defense stimulation effect or a bactericidal effect on or within said plant; and the at least one inorganic phosphite component further optionally consisting of sodium, lithium, potassium, salts of ammonium, alkaline earth metal nutrients, magnesium, calcium, barium, strontium, iron, nickel, cobalt, manganese, zinc or aluminum, monitoring said plant for improvement in condition and/or for infection by a bacterial disease; and reapplying said inorganic phosphite composition if necessary for treatment of a bacterial disease within a plant, with the caveat that the inorganic phosphite composition contains no organic components.
