Yellow Patch Disease The Pest Disease Clinic
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.
Using a slow release fertilizer to ensure moderate amounts of Nitrogen will help in reducing the chance of Yellow Patch. Reducing the leaf wetness period will also help prevent Yellow Patch. Night time watering can increase the leaf wetness period and lead to disease. Follow Weed Man's proper watering instructions! Allow for better air movement in order to help dry the lawn when moist. Remove excess thatch through regular aeration will also help alleviate compaction and improve drainage. Ensure that when mowing the lawn is mowed at a high level when dry and in the morning allowing for the grass blades time to heal. Early evening mowing will increase chance of Yellow Patch as well as a dull mower blade.
