2. Fungal diseases

3. Insect infestations

4. Watering practices

The correct answer is: Fungal diseases

Dollar Spot is primarily associated with fungal diseases, specifically caused by pathogens belonging to the genus Sclerotinia. This disease is a common issue in turf management and can lead to significant aesthetic and health issues for lawns and sports fields. Identifying Dollar Spot is essential for turf management because it manifests as small, round patches of straw-colored grass that can merge into larger areas if not addressed. The disease tends to thrive in conditions where grass is under stress due to factors like insufficient fertility, irregular watering, and high temperatures, but its defining characteristic lies in the specific fungal infection. By recognizing that Dollar Spot is a fungal disease, turf managers can implement targeted fungicide treatments and cultural practices aimed at improving grass health and minimizing the occurrence of this disease. Understanding Dollar Spot's association with fungal diseases informs proper disease management strategies crucial for maintaining healthy and attractive turf, making it a key focus for anyone involved in turf management.
