Abstract: Managing plant diseases is crucial for crop production, particularly for high-quality seed. Infections can lower yield and quality, and seeds can spread pathogens. Treatment of seeds can be beneficial when applied to weaker seeds, damaged seed coats, or when germination is delayed due to unfavorable soil or weather conditions. Fungicide application was once the primary method of seed treatment, but innovative approaches are becoming more necessary, especially in organic farming. The outcome of a seed treatment depends on the severity of internal seed infection, the quantity of inoculum in a seed lot, the specificity of the treatment, and potential phytotoxicity. Other types of therapy may include seed disinfestation, disinfection, and/or protection. Fungicides can be narrow spectrum (effective against a small number of species) or broad spectrum (toxic to all or many types of fungi). Contact fungicides have little effect on interior fungal seed infections, while translaminar or cytotropic fungicides can enter the outermost layers of seeds. Systemic fungicides are often more effective against deep-level fungi and provide protection against early infection from airborne and soilborne illnesses. Physical therapies involve heating seeds, such as hot water, hot air, and electron treatments. Hot water treatment is a well-known method for sanitizing tainted cereal seeds, while aerated steam and electron seed treatments are being researched for their effectiveness in various host-pathogen systems.
