What is the primary use of Fludioxonil?

Fludioxonil is primarily used as a fungicide to control various fungal infections, particularly those that affect seeds. In the context of potato seed treatment, it plays a critical role in managing tuber-borne pathogens, which can significantly impact plant health and crop productivity. By targeting diseases that are transmitted through seed tubers, Fludioxonil helps ensure that the planted seeds are healthier, allowing for better germination rates and establishment of the crop. This usage is vital in agricultural practices focused on maintaining seed quality and preventing the spread of soil-borne diseases.

Other options do not accurately represent the primary function of Fludioxonil, as it does not directly enhance plant growth, improve soil fertility, or increase crop yield in a general sense. Instead, its focus is specifically on disease control, which indirectly supports healthier plants and potentially better yields as a result of disease management.
