Lawn problems are difficult to diagnose,
and the diagnosis process can be quite complex. Remember that most
turfgrass problems are caused by improper management practices, not
by insects or diseases. Before you begin the diagnostic key, take
a look at how you manage your lawn. You may be able to solve your
problem by simply changing your cultural practices.
Answer the questions on the right before proceeding.
After you have answered the questions and can safely eliminate the
associated abiotic disorders from being the cause of your problem,
begin the diagnostic key. This key is a guide and does not include
all possible disorders. However, it should lead to a diagnosis for
most common problems. Refer to the section on "Diagnostic tips"
for more information.
