How to Identify Plant Diseases

How to Identify Plant Diseases

Knowing plant diseases is one part of landscape care. Here’s how you can spot a plant disease.

A healthy garden is a disease-free garden. It can be easy enough to hire a landscaping company to design and install a beautiful new lawn and garden for you in Maryland, but maintaining its health is another matter. Plant diseases can plague your plants without you being aware of it. These tips can help you begin to identify plant diseases at a detailed level.

Three Categories of Plant Diseases

There are three categories of plant diseases to recognize: fungal, bacterial, and viral. These three types define the cause of a plant disease. There is overlap between the different signs and symptoms that let you know which category the disease is, but familiarizing yourself with different specific diseases can help you determine the cause further.

Look for a Sign

There is a difference between the evidence of the disease itself and the sickness it causes the plant. Look for a sign of the disease itself as part of the identification process. 

Viruses will have no sign, because they are smaller than microscopic, but fungal and bacterial diseases are possible to see with the naked eye. 

Fungal plant diseases will usually reveal themselves through a powdery substance like a rust, mildew, or mold. Bacterial plant diseases may look like an unnatural ooze.

Look for a Symptom

The next step is to look for a symptom, the damage done to the plant by the fungal, bacterial, or viral disease. Identifying the symptom can help you find the cause. The symptoms of a plant disease are usually a change in leaf color, wilting, or a change in the plant’s function. Common symptoms of plant diseases include spots, cankers, yellowing leaves, strange leaf patterns, and stunted growth. Once you can identify plant diseases, you can go ahead with solving the issue.
