One day your lawn looks healthy and green. The next, you notice brown spots, discolored patches, or unusual markings spreading across the turf. Sound familiar? Recent rains and high humidity create the perfect environment for lawn diseases to develop—sometimes seemingly overnight.

The good news is that many common lawn diseases can be controlled when caught early. Knowing what to look for and using the right treatment can help restore your lawn and keep it looking its best throughout the growing season.

Why Are Spots Appearing in My Lawn?

Periods of frequent rainfall, heavy dew, and high humidity create ideal conditions for fungal diseases to thrive. Moisture that lingers on grass blades allows disease spores to spread quickly across the lawn.

Common symptoms include:

• Brown, tan, or yellow spots in the grass
• Circular patches that continue to expand
• Discolored leaf blades with dark spots or lesions
• Thin or weakened turf growth
• White, gray, or powdery growth on grass blades

One of the most common lawn diseases during wet conditions is leaf spot, which often appears as small brown or dark-colored lesions on grass blades before progressing into larger damaged areas.

Control Leaf Spot and Other Lawn Diseases

If you're seeing signs of disease, Bonide Infuse Disease Control Granules can help stop the problem before it spreads further.

Benefits of Infuse Disease Control Granules

• Controls a wide variety of common lawn diseases, including leaf spot
• Begins working quickly
• Helps prevent future disease outbreaks
• Easy to apply with a lawn spreader
• Covers up to 5,000 square feet

The systemic formula works throughout the plant to control and prevent many types of lawn diseases while helping protect healthy turf.

Dealing with Powdery Mildew?

Another common lawn issue during periods of abundant moisture is Powdery Mildew.

Powdery Mildew typically appears as:

• White or gray powdery coating on grass blades
• Thin, weakened turf
• Reduced vigor in shaded areas

This disease is especially common in spring when turf is growing rapidly, and moisture levels remain high.

For Powdery Mildew control, Earl May recommends Bonide Infuse Ready-To-Spray Disease Control.

Why Choose Infuse Ready-To-Spray?

• Contains a different active ingredient than the granules
• No mixing required
• Simply attach to a garden hose and spray
• Easy application for homeowners
• Controls and prevents multiple lawn diseases

When using this product, simply connect the bottle to your hose and begin spraying. It's a quick and convenient solution when disease symptoms first appear.

Pro Tips to Prevent Future Lawn Diseases

While treatments can effectively control active disease problems, prevention is always the best strategy.

Choose High-Quality Lawn Seed

When seeding or overseeding, select premium grass varieties that have demonstrated strong disease resistance.

At Earl May Garden Centers, we only carry grass seed varieties that have been tested under Midwest growing conditions, including periods of high humidity and moisture.

Important: No grass variety is completely immune to disease, but resistant varieties can significantly reduce future problems.

Avoid Mowing Wet Grass

Mowing when the lawn is damp can:

• Spread disease spores
• Damage grass blades
• Create openings for infection

Whenever possible, wait until the lawn has dried before mowing.

Mow More Frequently in Spring

During spring's active growth period:

• Mow slightly lower
• Mow more frequently
• Avoid removing more than one-third of the grass blade at a time

This helps improve airflow through the turf canopy and reduces conditions that favor disease development.

Improve Air Circulation

Areas with poor airflow often remain damp longer and are more susceptible to fungal issues. Consider:

• Pruning nearby shrubs and trees
• Reducing shade where possible
• Water in the morning, not in the evening

Better airflow means less moisture sitting on grass blades.

Quick Lawn Disease Prevention Checklist

Before disease becomes a problem, remember these simple steps:

• Use quality disease-resistant grass seed
• Avoid mowing when grass is wet
• Mow frequently during periods of rapid growth
• Water deeply but less often
• Improve air circulation around the lawn
• Treat disease early when symptoms first appear
