As seasons change, Canadian homeowners and landscape enthusiasts often encounter a common lawn disease, Microdochium Patch. This pesky fungus, or fusarium patch or pink snow mold, can wreak havoc on lawns, especially during the wet and cool spring months.
Understanding Microdochium Patch:
Microdochium Patch appears as small circular dead spots on lawns, with a distinct pinkish hue and fluffy white mycelia visible in the early morning. This fungus thrives in wet and cool conditions, making early detection crucial for adequate control. As one of the first diseases to emerge in spring, managing in a cold and wet climate can be challenging.

Symptoms of Microdochium Patch:
- Circular dead spots on the lawn with a pinkish coloration.
- The fluffy white mycelia is present early in the morning.
- Higher incidence in shaded or poorly drained areas

Preventive Measures
Prevention is key to managing Microdochium Patch effectively. Consider the following tips to keep your lawn healthy and fungus-free:
Early Preventive Application
Apply a preventive fungicide like Dedicate Stressgard in the fall before permanent snow cover to provide winter protection against snow mold diseases.
Monitor Weather Conditions
Be mindful of wet and cool weather patterns, especially during spring, which can lead to an outbreak of the disease.
Improve Lawn Drainage
Enhance the drainage in your lawn to reduce excess moisture accumulation, creating an unfavorable environment for the fungus.
Reduce Thatch
Regularly dethatch your lawn to minimize areas where the fungus can thrive.
Tips for Overall Lawn Care
Maintaining a healthy lawn is essential for disease prevention and overall curb appeal. Here are some additional tips:
- Set the mower at the appropriate height for your grass type and avoid cutting more than one-third of the grass height at a time.
- Consider aerating your lawn to improve soil compaction and allow better nutrient and water absorption.
- Apply balanced fertilizers to ensure your lawn receives essential nutrients for growth and resilience.
- Water your lawn deeply but infrequently, preferably in the morning, to prevent excess moisture leading to fungal growth.
