Fludioxonil

Type: Fungicide

Mode of Action: Inhibiting the ability of fungal spores to germinate

Common Product Names: Switch & Miravis Prime

What is it?

Fludioxonil is a synthetic fungicide that belongs to the phenylpyrrole class of chemicals. It was first introduced in the 1990s and has since become a staple in agricultural disease management strategies. Fludioxonil is highly effective against a broad spectrum of fungal pathogens, including those causing seed rot, stem rot, and storage diseases in harvested produce. Its versatility makes it suitable for use in various crops, ranging from cereals to fruits and vegetables. Fludioxonil is both curative and preventative in nature. It can be applied as a treatment for existing infections and as a preventative measure to protect crops from potential fungal attacks. In addition to field applications, Fludioxonil is often used post-harvest to protect stored fruits and vegetables from fungal decay.

How does it work?

Fludioxonil works by inhibiting the ability of fungal spores to germinate. It does this by interfering with the osmoregulation processes within the fungal cells, effectively preventing the fungus from developing and spreading. Specifically, Fludioxonil targets the histidine kinase enzyme in the fungal cell membranes, disrupting cellular processes and leading to the death of the fungus.
