ABSTRACT:
A method of eradicating unwanted vegetation, such as the marijuana plant, the method including the steps of preparing a predetermined concentration of fluorescein or like dye, the dye including a photodynamic pigment which in the presence of oxygen acts as a sensitizer for photo-oxidation in the vegetation, and applying a charge of the concentration of dye to soil in the vicinity of the roots of the vegetation, thereby leading to the absorption of the charge by the roots of the vegetation such that the dye will react with proteins, fatty acids, and lipids at cellular membranes of the vegetation causing membrane lipid peroxidation, and as a result of the reaction, causing the destruction of cells and tissues therein and the subsequent death of the vegetation.
