How to Combat Powdery Mildew in the Late Flowering Stage

As a commercial cannabis grower, you already know that powdery mildew in late flowering stage is one of the most common and problematic issues that can arise during the growing process. Powdery mildew is a fungal disease that affects a wide range of plants, including cannabis, and it can cause significant damage if left untreated. In the late flowering stage, powdery mildew can be incredibly challenging to manage, but there are effective ways to combat the disease and protect your plants. In this blog post, we will discuss what to do for powdery mildew in the late flowering stage of your cannabis plants.

Identify the Signs of Powdery Mildew In the Late Flowering Stage

The first step in managing powdery mildew is to identify the signs of the disease. In the late flowering stage, powdery mildew can appear as a white or grayish powder on the leaves and buds of your cannabis plants. Other signs of powdery mildew can include distorted growth, yellowing or browning of leaves, and a powdery or dusty appearance on the buds. Regularly monitoring your plants is critical to catching powdery mildew early and preventing it from spreading.

Remove Infected Plant Material

Once you have identified the presence of powdery mildew in your late-flowering cannabis plants, the next step is to remove any infected plant material. This includes leaves, buds, and even whole plants if necessary. Dispose of the infected material carefully and thoroughly to prevent the disease from spreading to healthy plants. Proper sanitation practices can also help prevent the spread of powdery mildew.

Use Fungicides as Needed

In some cases, fungicides may be necessary to control powdery mildew in the late flowering stage of cannabis growth. Various fungicides are available, and it’s essential to choose the right one for your particular situation. Follow the manufacturer’s instructions carefully, including application rates, timing, and precautions. Fungicides should be used as part of an integrated pest management strategy, and other management practices, including pruning and proper nutrition, should also be employed.

Monitor Humidity and Airflow

High humidity levels and poor airflow can contribute to the development and spread of powdery mildew. In the late flowering stage, it’s essential to closely monitor humidity levels and ensure good airflow throughout your growing area. Consider using dehumidifiers, fans, and other equipment to maintain optimal growing conditions for your cannabis plants.
