Chemotherapy is the treatment or cure of diseased plants by the application of chemical compounds. Chemotherapy differs from chemical properties by killing or inactivating the pathogen after it has infected the plant. The chemical compound is called a chemotherapeutant and may act locally at the site of infection as a topical therapeutant or may be distributed through the plant system as a systemic therapeutant.
