Lawn Diseases

Posted by John Fulton -

It has been a banner year for diseases in many plants. The lawns are starting to show some of the diseases as well. Conditions have been ideal for many of the fungi that cause up problems. Humidity makes an ideal environment for many diseases, but there are some that like drier conditions. Dollar spot, brown spot, and rust have been noted in area lawns.

There are treatments available for diseases in home lawns, but they can be rather expensive and time consuming. Treatments would be applied on a 7-14 day basis throughout the season. It isn't recommended for homeowners to treat diseases in the lawn. The recommendation is let nature take its course, and then do some reseeding if needed.

The disease needs a susceptible host, the right environment, and time to cause us problems. If you do some reseeding, use a newer variety with good disease resistance. This attacks the susceptible host part. Also, keep your turf growing well to prevent weakened grass plants from being more susceptible. The diseases will only be present during certain weather, and as the weather changes the diseases will go away.
