This disease is known to affect the root and crown of the strawberry plant. It causes browning on the edges of the leaves.

Strawberry plants are usually affected by verticillium wilt in their first year; however, there are strawberry varieties that are resistant to the disease.

4. Leaf Blight

Leaf blight is a fungal disease that is known to affect the growth of strawberry plants. It comes as black, tiny spots on the leaf and increases over time.

These black spots then turn to brown marks, with a reddish-purple border. Although it is almost impossible to get rid of leaf blight, you can slow down its spread with the use of fungicides. Ensure the fungicide you are using has copper, captan, and myclobutanil as ingredients.

Leaf scorch is regarded as the most common disease found in strawberry plants in the U.S. also known as ilocarpon earlianis, leaf scorch that appears as purple, red, or yellow on the leaves and even other parts of the plant.

Sometimes, some strawberry plants are usually already infected before they are purchased; hence you have to be observant to identify irregularities on your plant. As the infection progresses, the leaf begins to turn brown and then dies.
