What is Powdery Mildew?
Powdery mildew is a type of fungal disease that affects a wide variety of plants, including cannabis. The fungus responsible for this disease is called Erysiphe cichoracearum and is characterized by white, powdery spots on the leaves and stems of the plant. The spots can spread rapidly, eventually covering the entire plant if not treated. This disease can cause serious damage to your plant, resulting in stunted growth, reduced yields, and even plant death in extreme cases.
Causes of Powdery Mildew
The leading cause of powdery mildew on cannabis plants is poor air circulation. When the air is too still, the fungus spreads more quickly. In addition, high humidity and temperatures above 75°F can also contribute to the spread of powdery mildew. Other environmental factors, such as too much nitrogen or improper watering, can increase the risk of powdery mildew on cannabis plants.
Signs and Symptoms of Powdery Mildew
The main symptom of powdery mildew is the presence of white, powdery spots on the leaves and stems of the plant. These spots can range from small to large and cover the entire plant surface if left untreated. In addition, the leaves may turn yellow and curl as the disease progresses. The stems may become brittle in more severe cases, and the buds may be stunted or deformed.
Tips for Preventing Powdery Mildew on Cannabis Plants
You can do several things to reduce the risk of powdery mildew on your cannabis plants. First and foremost, ensure that you provide your plants with adequate air circulation. This can be done by positioning fans around the growing area and opening windows and doors when possible. In addition, you should monitor the humidity and temperature in the growing area and adjust accordingly.
Another important preventive measure is to make sure that your plants are getting enough light. Cannabis plants need at least 8 hours of direct sunlight each day to stay healthy and fight off disease. If your plants are not getting enough light, you may need to supplement them with grow lights.
Finally, it’s important to practice proper hygiene when growing cannabis. Sterilize any tools or containers you use to avoid spreading disease. In addition, don’t forget to wash your hands before and after handling your plants to avoid transferring pathogens.
Tips for Controlling Powdery Mildew on Cannabis Plants
If your plants are already infected with powdery mildew, you can still do some things to help control the situation. First, remove any infected parts of the plant to help prevent the disease from spreading further. You should also increase air circulation in the grow area to help speed up the drying process. In addition, you should adjust the humidity and temperature in the grow area to help slow the spread of the disease.
Finally, you can use some natural treatments to help control powdery mildew on your cannabis plants. One of the most effective treatments is a mixture of baking soda and water. Simply mix one teaspoon of baking soda with 1 quart of water and spray directly on the affected areas of the plant. This will help neutralize the plant’s pH levels and reduce the spread of the disease.
