Brown patch time again!

Sep 10, 2018 | yard insect control

With the late summer rains upon us and cooler weather just around the corner (no really!), it’s time we start thinking of lawn diseases such as brown patch. In fact, the fungus that causes brown patch, Rhizoctonia, can remain for years in the soil until conditions are optimum. Periods of rainy weather or high humidity combined with poor soil drainage and compacted soil are also conducive to this lawn disease.

Lawn damage from brown patch is usually evident in circular, or semi-circular patterns. It can be very frustrating to see what was once a nice stretch of green grass suddenly broken up with these spotty areas. Once you have confirmed this is definitely brown patch, rather than get upset, it’s time to take the bull by the horns.

Some of the things you can do to discourage or halt further brown patch damage are:

  • Aeration or dethatching. This improves circulation and loosens the soil.
  • When the rains do stop, and you start watering your lawn again, if at all possible, water your lawn in the morning to allow the moisture to dry off the leaf surface as quickly as possible during the day to discourage fungal growth.
  • Keep lawn mower blades sharp. Dull blades can provide a better surface area for fungus to enter the blades of grass.
  • A fungicide application may be needed. Keep in mind, a treatment does not reverse the browning effect.  It merely stops the spread of the fungus and will help the patches of brown come back green next Spring

Just remember, the combination of cooler temperatures, high humidity and water accumulation on uneven lawn surface depressions with drainage issues can provide the perfect conditions for most fungal diseases to thrive.
