Protectants are used as a preventive measure, applied before disease pressure to form a protective barrier or inhibit initial infection. Eradicants are used after disease is present, to reduce or eradicate the existing infection and slow its spread. Therefore, the best timing is to apply protectants before disease develops and use eradicants after symptoms appear. This sequencing aligns with how each type works: stop infections from taking hold versus tackling infections that are already evident.
