As the vibrant green of St. Augustine lawns begins to fade into unsightly brown patches, homeowners and lawn enthusiasts face a common adversary: Brown Patch and Large Patch fungus. These lawn diseases can turn a lush, healthy yard into a spotty, brown eyesore. At Green Smart Lawn & Pest, we understand how crucial it is to maintain the health and appearance of your lawn. In this article, we’ll delve into effective strategies to prevent and treat these common fungal issues.
Understanding the Enemy: Brown Patch & Large Patch Fungus
Brown Patch and Large Patch are caused by different strains of the Rhizoctonia fungus. Brown Patch typically occurs in late spring and fall, thriving in temperatures between 70-90°F, whereas Large Patch is more common in cooler temperatures, often appearing in early spring or late fall.
Symptoms to Watch For
- Circular patches of brown, dying grass.
- Yellowing or wilting at the edges of the affected areas.
- Grayish, cottony mycelium under moist conditions.
Preventive Measures
- Proper Watering: Water your lawn deeply but infrequently to avoid prolonged moisture on grass blades, which can foster fungal growth.
- Appropriate Fertilization: Over-fertilizing, especially with high nitrogen fertilizers, can increase susceptibility to fungus. Use balanced, slow-release fertilizers.
- Regular Mowing: Keep your lawn at the recommended height for St. Augustine grass, avoiding cutting more than one-third of the grass blade at a time.
Treatment Strategies
- Fungicides: At the first sign of infection, apply a fungicide specifically designed for Brown Patch and Large Patch. Repeat applications may be necessary.
- Lawn Care Practices: Enhance air circulation by aerating your lawn and removing thatch buildup.
- Recovery and Maintenance: After treatment, continue with proper lawn care practices to prevent recurrence.
