Which type of fungicide moves through the plant and can kill fungal pathogens that are already in the plant?

Explanation:
Movement through the plant is the giveaway for a systemic fungicide. Systemic products are absorbed by roots or foliage and travel inside the plant, so they can reach and kill fungal pathogens that have already established within tissues. Protectant fungicides stay on the surface, forming a barrier to prevent new infections but they don’t move inside, so they’re not effective at eliminating pathogens that are already inside. The other options are disease names, not a type of fungicide, so they don’t describe how the product works inside the plant.
