- Bacteria, fungi, molds, and viruses are the main culprits behind strawberry plant diseases.
- Organic growers have options to reduce strawberry diseases, such as using copper sprays and validamycin for controlling angular leaf spot.
– Proper soil management, including soil pretreatment and solarizing, can help prevent diseases like anthracnose and charcoal rot.
Common Strawberry Diseases
Common strawberry diseases, caused by bacteria, fungi, molds, and viruses, can affect various parts of the strawberry plant and can lead to plant death if not properly managed. These diseases can impact the fruit, flowers, leaves, roots, and crowns of the plants.
Some diseases, such as angular leaf spot caused by Xanthomonas fragariae bacteria, can result in sudden plant collapse.
Anthracnose, a fungal infection characterized by orange spore ooze, can be spread by overhead splashing water.
Leather rot, another common fungal infection, can affect strawberries at any stage of development.
Bortrytis fruit rot turns ripe strawberries into gray mold, while charcoal rot caused by the fungus Macrophomina phaesolina infects roots and crowns.
Fusarium wilt, leaf blotch, mucor fruit rot, pallidosis, phytophthera rot, powdery mildew, and verticillium wilt are among the other common strawberry diseases that growers must battle.
Proper management strategies, such as soil management, disease-free plant selection, and the use of fungicides, can help control these diseases and ensure healthy strawberry plants.
Causes and Symptoms
Causes and symptoms of strawberry plant diseases include the presence of bacteria, fungi, molds, and viruses that can affect various parts of the plant, leading to potential plant collapse and death. These diseases can affect the fruit, flowers, leaves, roots, and crowns of the plants. Bacterial diseases such as angular leaf spot caused by Xanthomonas fragariae can result in sudden plant death, while fungal infections like anthracnose and leather rot can cause brown spots on the strawberries and affect their development. Viral diseases like pallidosis can cause mottling, crinkling, and yellowing of the leaves without significant fruit damage. To help visualize the causes and symptoms of these diseases, the following table provides a summary:
| Disease | Cause | Symptoms |
|---|---|---|
| Angular Leaf Spot | Xanthomonas fragariae bacteria | Sudden plant death |
| Anthracnose | Fungal infection | Orange spore ooze, brown spots on fruit |
| Leather Rot | Fungal infection | Brown spots during wet weather |
| Pallidosis | Viral disease | Mottling, crinkling, yellowing of leaves |
Understanding these causes and symptoms is crucial for effective disease management and prevention in strawberry plants.
Prevention and Management
Prevention and management strategies play a vital role in safeguarding the health and vitality of strawberry plants against the pernicious onslaught of microbial adversaries. To ensure the well-being of strawberry plants, the following measures can be implemented:
- Implement good soil management practices, such as proper drainage and soil solarization, to minimize the risk of fungal infections like anthracnose and charcoal rot.
- Practice crop rotation and avoid planting strawberries near plants susceptible to diseases like anthracnose to reduce the spread of pathogens.
- Opt for disease-resistant strawberry varieties to minimize the risk of infections.
- Employ cultural practices like adequate plant spacing, early fruit picking, and barrier mulch to prevent the development and spread of diseases like leather rot.
By implementing these preventive measures, strawberry growers can effectively manage and mitigate the impact of bacterial, fungal, mold, and viral diseases on their plants, ensuring a healthy and abundant harvest.
Treatment Options
Treatment options for strawberry plant diseases include the use of copper sprays, validamycin, hot water immersion, and fungicides like Abound, Switch, sulfur, or soaps, depending on the specific disease being targeted.
Copper sprays and validamycin can effectively control angular leaf spot caused by Xanthomonas fragariae bacteria, while hot water immersion can kill anthracnose and fungicides like Abound and Switch can be used to treat transplants. Fungicides can also be used as a last resort for leather rot, which affects strawberries in any stage of development.
Chilling strawberries after harvest can prevent bortrytis fruit rot, and beneficial bacteria sprays and potassium bicarbonate can be used to fight against it. Solarization, crop rotation, and planting resistant varieties are effective in controlling charcoal rot and Fusarium wilt.
Preventive applications of sulfur or soaps can help prevent powdery mildew, although their cost may outweigh the value of strawberries for home gardeners. Unfortunately, there are no fungicides available to control verticillium wilt once it is in the soil.

Frequently Asked Questions
How can strawberry diseases affect the overall health of the plant?
Strawberry diseases can devastate the overall health of the plant, leading to plant collapse and death. They can affect the fruit, flowers, leaves, roots, and crowns, causing damage and reducing productivity. Prevention and management strategies are crucial to maintain plant health.
What are some organic methods to reduce strawberry diseases?
Organic methods to reduce strawberry diseases include using copper sprays and validamycin to control angular leaf spot, immersing plants in hot water to kill anthracnose, practicing good soil management, and using barrier mulch to prevent leather rot.
How can angular leaf spot be controlled in strawberry plants?
Angular leaf spot in strawberry plants can be controlled by using copper sprays and validamycin. These treatments effectively manage the bacteria responsible for the disease, preventing sudden plant death and promoting healthier plant growth.
What are some ways to prevent the spread of anthracnose in strawberries?
To prevent the spread of anthracnose in strawberries, it is important to remove infected plants, avoid overhead watering, and practice proper soil management. Hot water treatment, fungicides, and planting strawberries near certain plants can also help control the disease.
How can leather rot be prevented and treated in strawberry plants?
Leather rot in strawberry plants can be prevented by ensuring good soil drainage, using barrier mulch, planting in full sun and parallel to prevailing winds, spacing plants adequately, and removing strawberries with brown spots promptly. Fungicides can be used as a last resort.
