Dollar spot is especially prone to fungicide resistance, so it is even more important to rotate and take steps to prevent a fungicide-resistant disease.
- Rotate the active ingredients you use when treating for this disease. The Mode of Action chart on the bag of your fungicide is a handy resource to see the many different categories of active ingredients, so you can choose an effective rotation of products. More information about fungicide rotation can be found in our fungicide guide.
- Only apply products when necessary. Limiting the number of applications can prevent resistance.
- Combining fungicide applications with cultural practices not only reduces the amount of fungicide you need to use, but it reduces the potential for future disease, which limits fungicide exposure.
