Strawberry Plant Diseases

Alkali Yellows

• Alkali yellows is a disease caused by strong alkaline soil, which causes iron or manganese to be unavailable to strawberry plants. Symptoms do not occur on flowers or fruit, but leaves of a strawberry plant can be small or look white.

Armillaria Root Rot

• Armillaria root rot is a white fungus that attacks the crown and roots of a strawberry plant.

Black Root Rot Complex

• Black root rot complex is a combination of fungus, nematodes and poor soil characteristics. Symptoms include black discolorations on roots, and smaller foliage with poor color.

Common Leaf Spot

• Common leaf spot is a fungus that infects strawberry plant leaves. Symptoms include dark, almost purple spots on leaves.

Gray Mold (Botrytis Fruit Rot)

• Gray mold is a fungus that affects the entire strawberry plant, including fruit, which will have fuzzy mold growing on its surface.

Leaf Scorch

• Leaf scorch is another fungus that attacks strawberry plant leaves. Leaves will appear with numerous red spots, giving them a scorched look. In severe cases, foliage is reduced considerably, and plants may be stunted.
