What is white mold and what causes it in the garden?
White mold, also known as sclerotinia, is a fungal disease that affects various plants, particularly those in the vegetable family such as beans, tomatoes, and peppers. It appears as a white, fluffy fungal growth on the stems, leaves, or fruits of infected plants. The disease thrives in cool, moist conditions, making gardens that have poor air circulation or over-irrigated plants particularly susceptible.
The primary causes of white mold include high humidity, excessive moisture, dense planting, and poor soil drainage. When these conditions combine, they create an ideal environment for the fungus to thrive. Additionally, infected plant debris in the soil can serve as a source of the pathogen, leading to a recurring problem if not managed properly.
How can I identify white mold in my garden?
Identifying white mold in your garden typically involves looking for specific symptoms. The most noticeable sign is the presence of a white, cottony fungal growth that often develops on the stems or under the leaves of affected plants. In some cases, you might also find brown spots or wilting on the foliage, particularly near the bases of stems. If left unchecked, the fungus can lead to the complete collapse of the plant.
Another sign of white mold is the formation of small, hard black structures called sclerotia, which can often be found nestled within the white mold. These sclerotia can survive in the soil for several years, potentially infecting future crops. If you suspect white mold, it’s essential to act quickly to prevent it from spreading throughout your garden.
