What action is taken when applying a fungicide to eliminate a disease?

The choice of curative action when applying a fungicide to eliminate a disease is appropriate because it refers to the application of a fungicide once a fungal infection has already occurred in the crop. This method focuses on treating the existing disease to reduce its impact and promote recovery in the affected plants. Curative fungicides are formulated to eradicate the pathogens and limit their spread, helping to restore the health of the crop.

On the other hand, preventive actions, which are intended to stop diseases from occurring in the first place, are not the focus when discussing the elimination of an existing disease. While preventive fungicides can play a crucial role in overall disease management strategies, they do not directly address current infections. Transitional and systematic options do not accurately reflect the process of eliminating a disease through fungicide application either, as they are not typically used in the context of addressing active diseases directly.
