An eradicant fungicide is primarily designed to eliminate established fungal infections in plants and is generally systemic in nature. This means that it is absorbed by the plant and can be translocated throughout its tissues, allowing for effective management of the fungus that may be located in different parts of the plant.

Systemic fungicides provide a more comprehensive approach to controlling fungal pathogens because they reach areas within the plant that might be difficult for contact fungicides to penetrate. This is particularly important for addressing fungal diseases that may not be visible on the surface of the plant but are nonetheless thriving inside the tissue.

While it's true that some formulations of fungicides can be contact-based or have limited systemic properties depending on various factors (such as the particular conditions or how the formulation is applied), the essence of an eradicant fungicide leaning towards being systemic aligns with its primary purpose of treating infections effectively throughout the plant's structure. Hence, stating that an eradicant fungicide is generally systemic aligns with its intended function and typical characteristics in plant protection.
