Yellow Patch

Conditions Favoring the Disease

Yellow Patch is most prevalent from late fall to early spring when temperatures are less than 60°F (16°C). It occurs in areas that receive more than 10 hours of leaf wetness for several days in a row and on turf that has excessive thatch and high nitrogen levels. Poor mowing habits like a dull mower blade can increase the probability of Yellow Patch by leaving the turfgrass blades exposed to the disease.

Managing Yellow Patch
  • Use a slow-release fertilizer to ensure moderate amounts of Nitrogen
  • Reduce the leaf wetness period
  • Avoid nighttime watering can as this can increase the leaf wetness period and lead to disease
  • Allow for better air movement in order to help dry the lawn when moist
  • Remove excess thatch through regular aeration will help alleviate compaction and improve drainage
  • Ensure that when mowing, the lawn is mowed at a high level when dry
  • Allowing the grass blades time to heal in the morning
  • Avoid early-evening mowing as this will increase the chance of Yellow Patch as well as a dull mower blade
