Fungicides that may become an integral part of soybean production are already used in corn and small grain production under certain situations. Since fungal pathogens are often highly variable and may be able to adapt to repeated fungicide sprays, resistance management may become an issue. It is important to protect effective groups of fungicides because resistance may lead to unexpected and costly crop losses to growers, and loss of a valuable product.
