The best way to prevent brown patch or large patch without fungicide

Prevention & Treatment without fungicide

The best way to prevent brown patch or large patch in the home lawn is by following good lawn care practices without using fungicide. This is much easier and less expensive than the use of fungicides and can be very effective.

  • Avoid high rates of nitrogen fertilizer on cool-season grasses in the late spring and summer. Avoid high nitrogen rates on warm-season grasses in mid to late fall or in early spring. The disease-causing fungus readily attacks the lush growth of grass which nitrogen promotes. Avoid fast-release forms of nitrogen fertilizer.
  • Irrigate grass only when needed and to a depth of 4 to 6 inches (generally 1 inch of irrigation water per week), but do not subject the lawn to drought conditions. Water early in the morning. This disease can spread fast when free moisture is present, especially greater than 10 hours.
  • Avoid spreading the disease to other areas. Remove clippings if the weather is warm and moist to prevent spread to other areas during mowing.
  • Keep lawns mowed on a regular basis to the proper height for the grass species you are growing. Lower than optimum mowing height can increase disease severity.
  • Provide good drainage for both surface and subsurface areas. Correct soil compaction by core aeration. Prevent excessive thatch buildup.
  • Have the soil tested, and apply lime according to test recommendations. Disease may be more severe if the soil pH is less than 6.0.
