Which fungicide type is absorbed by and moves inside the plant?

The correct choice is systemic fungicide because these are specifically formulated to be absorbed by the plant’s tissues, allowing them to move internally through the vascular system. This internal movement enhances their efficacy in controlling fungal diseases that may develop inside the plant, providing both preventive and curative effects.

Systemic fungicides are beneficial for managing diseases that might be difficult to reach with contact fungicides, which only target pathogens on the plant's surface without penetrating the tissues. Additionally, preventive fungicides are geared towards preventing disease establishment rather than being absorbed and moving within the plant, while fumigants are gaseous pesticides used to control pests in soil or enclosed spaces rather than being absorbed by plants. Thus, systemic fungicides are indispensable in integrated pest management for their ability to protect the entire plant from infections.
