In many cases, resistance is a contributing factor in unsatisfactory fungicide performance. Fungicide resistance occurs when a once-effective active ingredient is no longer able to stop pathogen growth and control disease. The phrase “once-effective” is essential to understanding fungicide resistance. It implies that something has changed in the pathogen to reduce the efficacy of a fungicide. The change is genetic, meaning the resistance trait can be passed on to future pathogen generations. Pathogen strains that are not resistant are said to be sensitive – i.e., sensitive to a fungicide’s effect. Although the term “insensitive” is sometimes used to describe fungicide resistance, the term “resistant” is used here with the understanding that there are different degrees of resistance depending on the pathogen and fungicide. This narrative provides an overview of fungicide resistance, addressing the fundamental elements and practical consequences as it relates to turf disease control.
