3.2 Fungal Diseases

Fungi are a type of organism that can cause a variety of diseases in strawberries. These diseases can range from mild to severe, and can affect the leaves, fruit, and roots of the plants. Some of the most common fungal diseases that affect strawberries include:

• Powdery mildew: This disease is caused by the fungus Sphaerotheca macularis. It is characterized by a white, powdery growth on the leaves of the plant. Powdery mildew can stunt the growth of the plants and reduce their yield.
• Leaf spot: This disease is caused by a variety of fungi, including Colletotrichum acutatum and Diplocarpon earlianum. It is characterized by small, brown spots on the leaves of the plant. Leaf spot can cause the leaves to wilt and die.
• Botrytis blight: This disease is caused by the fungus Botrytis cinerea. It is characterized by a gray, fuzzy growth on the leaves, fruit, and stems of the plant. Botrytis blight can cause the leaves to wilt and die, and can also lead to the rotting of the fruit.
• Verticillium wilt: This disease is caused by the fungus Verticillium dahliae. It is characterized by wilting and yellowing of the leaves, starting at the bottom of the plant. Verticillium wilt can eventually kill the plant.
• Rhizoctonia crown rot: This disease is caused by the fungus Rhizoctonia solani. It is characterized by a rotting of the roots and crown of the plant. Rhizoctonia crown rot can eventually kill the plant.

If you suspect that your strawberry plants are infected with a fungal disease, there are a few things you can do to treat the problem. First, you can remove any infected leaves or fruit from the plants. You can also apply a fungicide to the plants to help prevent the spread of the disease. Some common fungicides that can be used to treat strawberry fungal diseases include:

• Mancozeb: This fungicide is effective against a variety of fungal diseases, including powdery mildew, leaf spot, and botrytis blight.
• Propiconazole: This fungicide is effective against a variety of fungal diseases, including powdery mildew, leaf spot, and verticillium wilt.
• Thiophanate-methyl: This fungicide is effective against a variety of fungal diseases, including powdery mildew, leaf spot, and rhizoctonia crown rot.

It is important to follow the directions on the fungicide label carefully when applying it to your plants. Be sure to wear gloves and eye protection when applying the fungicide, and avoid spraying it on any nearby plants or flowers.
