Powdery mildew is the most common of the fungal diseases affecting plants in your garden if not controlled well. The infection usually manifests itself as a whitish or light greyish powdery mold on the leaves stems, and buds of many plants. As the infection progresses, the fungus disrupts photosynthesis, which can make your plants weakened, stunted, and unable to produce. In extreme cases, it causes death. Fortunately, there are some effective methods for treating mildew to prevent and control the infection of powdery mildew, and through proper gardening disease control techniques, you will keep your plants healthy and thriving.
Powdery mildew results from several fungal species in Erysiphaceae. Unlike all other types of fungi, this type does not need moisture and thrives only in warm dry conditions. Powdery mildew usually exhibits a fine white or powdery deposit on the surface of leaves, stems, and flowers, and it is usually evident on the surface of the foliage.
Powdery mildew infects the plant by entering into the cells and sucking the nutrients from the cells, weakening the plant as a whole. As time passes, the fungus continues to spread throughout the plant and affects various parts of the plant, leading to distorted growth, yellowing leaves, and reduced vigour. Eventually, if not treated, it can cause the death of the plant.
Prevention is always better than cure when it comes to mildew treatment. However, if your plants are already showing signs of powdery mildew, you have to take prompt action in order not to let the disease spread. There are various methods you can use, such as organic and chemical treatments.
The first approach to the control of powdery mildew is to cut off infected parts of the plants. This might involve cutting down leaves, stems, or flowers that are already infected with the fungus. Proper disposal of such infected material in the form of burning or keeping it in the trash can also be recommended; composting will only allow its spread to more plants.
Additionally, cleaning out dead leaves and any other organic debris around the plants may further enhance air circulation while reducing the humidity level and thus eliminating some of the pleasant conditions for the reproduction of powdery mildew.
Organic fungicides have been recommended as a great and safe alternative option for garden diseases control for naturalists. Made from natural components, organic fungicides can thus help in containing the spread of powdery mildew, without harming insects like bees that are beneficial in pollination activities or contaminating the environment with harmful chemicals.
Some of the popular organic fungicides include neem oil, sulfur, and potassium bicarbonate. These can help to prevent powdery mildew growth while inhibiting additional infection. This can be directly applied on infected plants based on the label guidelines of the products.
Benefits of Organic Fungicides
However, organic fungicides may be applied more often than their synthetic counterparts, and they do not necessarily act as fast in severe infections.
For a severe or persistent powdery mildew infestation, chemical fungicides may be the best bet for faster and more reliable success. However, chemical treatments must be applied with caution to avoid harming beneficial organisms or causing negative environmental consequences.
Look for a fungicide that contains chemicals and has been labelled to use against powdery mildew. Apply according to the label instructions for any chemical fungicide. The following are common chemical fungicides that contain sulfur, copper, or potassium salts.
Key Considerations for Using Chemical Fungicides
It is much easier to prevent powdery mildew than to treat it, and there are a number of garden disease control practices that can help protect your plants from this destructive fungus.
Another preventive measure against powdery mildew is by providing enough space between your plants to allow proper air circulation. Crowded plants trap moisture, creating a humid environment that fosters the development of fungal diseases. By spacing your plants properly, you let air circulate freely around the foliage, thereby reducing humidity and lowering the chance of powdery mildew.
Another thing that will help prevent powdery mildew is watering the plants right. Avoid overhead watering, which allows water to seep into the leaves, and this encourages fungal growth. It is best to water the plant at the base, where it can absorb into the soil but not drown the roots. Water your plants in the morning, so that when the evening rolls around, the leaves will be dry. The leaves of wet plants left wet overnight are likely to get infected with powdery mildew.
Most especially, if you are growing plants that can be easily susceptible to powdery mildew, consider using resistant varieties. Most nurseries and garden centres carry mildew-resistant varieties of the most common crops, like cucumber, squash, and pumpkin. These plants are bred for resistance to fungal infection, which helps decrease the chance of getting powdery mildew.
Healthy plants are not as susceptible to diseases so keeping overall plant health is an important prevention method for the development of mildew on your plants. The right amount of nutrients, adequate sunlight, and proper care will give your plants a strong and healthy framework, making them harder for powdery mildew to penetrate.
Weeds are also capable of harboring fungal spores. Further, weeds also spread the cases of powdery mildew, so weed-free gardens are important. Use regular methods for removing weeds, especially where they are near susceptible plants. This will reduce the chance of fungi infections in your garden.
Beyond the common treatment of mildew and garden disease control practices, other plant health tips can help prevent the growth of mildew:
Powdery mildew can be a terrible fungal plant disease that is horrible enough for your garden when it is allowed to proliferate. But with the appropriate methods of mildew treatment, using organic fungicides as well as following proper garden disease control practices, you can protect and keep your plants healthy. You will significantly reduce the possibility of powdery mildew attacking your plants if you allow enough space between them water them the right way and maintain good plant health. Early detection of this disease helps prevent it from spreading and further damaging your plants. It means early proactive treatments.
