The growth of powdery mildew or PM is one of the most common problems in cannabis horticulture. This problem came from a mix of a variety of fungi and any garden can be vulnerable, whether it’s indoors or outdoors.
This disease can cause photosynthesis to be severely compromised and the plant’s defenses to be weakened. This makes the crop susceptible to other diseases and pests and inevitably ruining the entire grow operation.
Therefore, the ideal way to deal with this issue is to prevent its growth in the first place.
Controlling Powdery Mildew
Typically, PM has the gray or white color and the bold contrast it creates on the leaves are indications of its presence.
The culprits are the spores that float freely on the wind through ventilation systems, pets or any other living things. It’s an issue that is difficult to detect when it will attack since it stays dormant until the environment becomes ideal for it to strike. It thrives in overcrowded damp grow rooms with little air flowing in the space.
Additionally, it normally feeds on the youngest crops and consumes it entirely. Once it spreads, it will be extremely hard to eliminate. As its reach grow deeper on the crops, the leaves and the entire structure will turn yellow, then brown, until it perishes completely.
Hence, it is critical to hinder these fungi from reaching this point. Keeping a close eye on the crops is key to control the problem.
Signs of PM Outbreak
Checking the cannabis leaves for any odd changes can help stop an infestation. An early indicator is the appearance of small bumps on the topsides of the leaves. Another most common sign is the fuzzy, powder-like round patches on the leaves can be spotted easily. If left unchecked, it could grow into a gray or white powdery compound which can cover a large area of the leaves. These spots will eventually mottle and wilt the infected area. Right around this time, it will begin to contaminate nearby leaves and eventually the entire crop.
The leaves turning to yellow from vibrant green is another indicator to watch out for. Moreover, its typical for molds to appear also as the humidity increases. It is then to be expected that various types of molds can join PM in wreaking havoc to the plants.
Getting Rid of PM
Immediately after noticing the early signs of PM, it is imperative to remove it as fast as possible. Fortunately, there are several effortless ways to control the problem.
Homemade remedies using apple cider vinegar, oil from neem and sesame seeds, fish oil and even milk sprays can do the trick. These sprays can also be used as a preventive measure.
Gently wiping the areas with a wet paper towel is another easy way to get rid of the problem. Effective PM sprays can be purchased as well.
Avoiding PM invasion
To further reiterate, the best way to deal with PM is to prevent it before it even starts. Some methods to guarantee PM-free cannabis plants includes buying strong high-quality seeds from reputable sources. Allotting an adequate grow space to avoid plant overcrowding and ensuring there is constant air flowing can also fend off this issue.
Ample lighting using UVC light makes it hard for the spores to attach to the surface and grow. Providing sufficient hydration without overwatering helps too.
Other sprays composed of oil from coriander, cinnamon, clove, cottonseed, limonene, hydrogen peroxide, garlic, and jojoba are great preventative sprays as well. These sprays are known to also heal infected plants.
Similarly, commercial products are alternative methods for helping the plants resist PM.
