What to Look for In Common Fungal Diseases in Plants

Fungal Diseases in PlantsWhen cultivating healthy medical marijuana plants, there are a lot of variables to track. Humidity, temperature, light, soil pH, and soil nutrients all impact a plant’s ability to thrive. In addition to these environmental variables, it is important to identify potential threats in the form of disease. Fungal diseases are among the most prominent pathogens to target cannabis plants. Recognizing warning signs of fungal diseases in plants will help you keep your crop from succumbing to infection.

Fungal Diseases in Plants

Gray mold is among the most common and virulent fungal diseases in plants. Another common fungal problem is damping off, a fungal infection that kills seedlings during their earliest days of life. Adult plants may be impacted by powdery mildew, hemp canker, downy mildew, fusarium wilt, or pink rot. Carefully checking your plants for signs of disease can help you prevent the spread of fungal spores throughout your indoor growing environment.

Common Signs of Fungal Diseases in Plants

Gray mold, caused by Botrytis cinerea, can wipe out an entire cannabis crop within a week. This fungus is one of the most common causes of damping off, an infection that affects seedlings. When cultivating seedlings, check for seedlings that fail to emerge. This is a sign that fungal spores have attacked the seedling before it reached the soil surface. For existing seedlings, look for weak plant bases. Plants suffering from damping off typically topple over or struggle to grow straight.

Mature plants often present with stem disease when gray mold or other fungal diseases are present. Check the stems of your plants for gray-brown fungal fibers. Stems that snap easily may be a sign that gray mold has created cankers. Discolored lesions on the stems or branches could be a sign of hemp canker, a common fungal infection.

Leaves also show signs of fungal disease. If your plants show yellow or brown spots on their leaves, they may be suffering from fungal infection. Fungi causing leaf spot will rarely kill a plant outright, but they significantly decrease yield.

Finally, it is important to check the flowering tops of cannabis plants. Female buds are highly susceptible to fungal infection. Check for fan leaflets turning yellowish or pistils turning brown. These are early signs of the disease. Once the disease has spread, buds will become covered in fungal fibers and eventually turn into slime.
