Focus on Correcting Cultural Management Methods First

The majority of the disease problems experienced on home lawns can be managed by ensuring the following practices are adhered to.

Make sure the lawn is being properly watered.
Over watering creates an environment that is perfect for fungal diseases to spread. Make sure the surface of the lawn is allowed to dry out between waterings, as this will kill or inhibit the disease.

Water in the early morning
Watering in the afternoon results in a significant amount of the watering being lost to evaporation, and this leads to shallow watering and shallow root development and ultimately poor drought tolerance.
Watering in the evening results in the lawn staying wet for the entire night before the sun can dry off the lawn the following day. This wet environment is conducive to disease development.

Sharpen Your Mower Blade
A dull mower blade shreds the leaf blades rather than cuts them. The shredded blade does not heal over well and is easily infected by some disease organisms. The shredded blades also brown off and make your lawn look brown and unhealthy.

Mow at the Proper Height and Frequency
Avoid cutting to low as this will stress out the lawn and make it more susceptible to disease. Also, mow frequently enough so that only one third of the leaf blade is removed at each mowing. If you wait to long between mowings, and then cut low, the lawn will go into a state of shock and this added stress makes the lawn more disease susceptible.

Aerate the Soil Annually
Aeration reduces soil compaction and allows water and nutrients to move deeper into the soil and encourages deeper roots. This results in a healthier lawn better able to resist disease. The soil cores that are removed from the lawn breakdown, filter into the thatch layer, modify the thatch and introduce beneficial microbes that compete with disease causing organisms.

Ensure a Balanced Diet of Fertilizer
Too much fertilizer can create succulent leaves that are more susceptible to disease. Too little fertilizer can create a weak unhealthy lawn. Our programs modify the type and quantity of fertilizers applied throughout the season to ensure a balanced diet.

Over-seed or slit seed with new, disease resistant cultivars of turf grass.
If your lawn suffers from a reoccurring disease problem then we strongly recommend that you over-seed or slit seed with some new lawn seed that is resistant to the problem disease.

Using Fungicides to Control Disease on a Home Lawn

Fungicides can control a wide variety of diseases, but it is important to identify and correct the reason the disease exists, or the disease will reoccur after the fungicide application has dissipated. Make sure the above guidelines are being followed. We strongly recommend over-seeding or slit seeding a lawn that suffers from a reoccurring disease problem.
Fungicide applications are also expensive and often require repetitive applications throughout the growing season in order to be effective. The vast majority of turf grass fungicides are applied to putting greens on golf courses where the turf grass is under a lot of stress due to the low mowing and heavy traffic. Home lawns do not generally suffer the same traffic stresses and are not mowed at ultra low cutting heights and so can generally recover without the use of fungicides.
