Fungicides and Fungicide Resistance
Vegetable crop diseases are often caused by fungi. Examples of foliar diseases caused by fungi include: downy mildew, powdery mildew and white blister. Examples of soilborne fungal diseases include: clubroot and diseases cause by Pythium, Fusarium, Rhizoctonia, Sclerotinia and Sclerotium species.
Fungicide resistance occurs when a fungicide or active-ingredient that was once effective, becomes no longer effective. It can occur when reduced rates of fungicides are used or when fungicides are over-used.
