fungicide resistance

Fungicide resistance occurs when fungal populations develop a reduced sensitivity to a specific fungicide. This phenomenon can emerge rapidly, as a single fungus can generate millions of spores. The overuse of fungicides, similar to herbicides, insecticides, and antibiotics, contributes to the evolution of resistance in certain fungal species.1

Fungicides are toxic substances designed to kill or inhibit the growth of fungi. They are commonly used to manage parasitic fungi that cause damage to crops, ornamental plants, or pose health risks to animals and humans. Fungicides can be applied as sprays, dusts, or seed coverings. Systemic fungicides are absorbed by plants to combat existing diseases or prevent future ones. In medicine, they are used topically or orally to treat fungal infections.1

While early fungicides included substances like Bordeaux mixture, modern agriculture often relies on synthetic organic compounds for broader control. However, the development of resistance highlights the importance of responsible fungicide use.1
