Cannabis Pythium: What Is It & How To Treat Root Rots

Cannabis is one of the most popular and widely used plants in the world for both recreational and medicinal purposes. However, despite its popularity and widespread use, growing cannabis plants is not always straightforward. Many factors can impact the growth of cannabis plants, including various diseases and infections.

One of the most mysterious and poorly understood diseases affecting cannabis plants is Cannabis Pythium. If you are growing cannabis or facing this problem, then you must read this post till the end.

We have shared everything related to cannabis pythium along with its symptoms, causes, and prevention so you can keep your cannabis plants healthy. Understanding more about it will help you maintain the proper growth and development of your plants.

What Is Cannabis Pythium?

Cannabis Pythium is a fungal disease that can cause serious damage to marijuana plants. It is caused by the Pythium fungi and is most commonly found in grow rooms and greenhouses where conditions are moist and humid. Pythium affects the root systems of marijuana plants, causing the roots to rot and the plant to become stunted or even die.

This can result in reduced yields, poor plant growth, and a decrease in the overall quality of the harvested crops. While the exact causes of Cannabis Pythium are not well understood, it is believed to be a soil-borne fungus that is commonly found in overwatered and poorly drained soils.

Symptoms of Cannabis Pythium

There are several symptoms of cannabis pythium, which can help to diagnose the disease early on and prevent further spread. You must pay attention to the changes coming in your plants as they indicate something wrong with their development. By looking at the symptoms, you will be able to diagnose the real problem and it will help you in starting the treatment. Here are some common symptoms to look out for:

Yellowing Leaves – Yellowing leaves are a common symptom of cannabis pythium, as the fungus attacks the roots and disrupts the plant’s ability to absorb nutrients. Leaves at the bottom will start getting yellow first, as they are the closest to roots, and then the yellowness will start going upwards to the top.

Stunted Growth – Pythium can cause the roots to rot, which can lead to stunted plant growth. If you are keeping a track record of the growth of your plant and notice that all of a sudden, it is showing no growth signs, then there can be a chance that the roots are having pythium issues, and you need to fix it asap.

Wilting – Plants infected with pythium may wilt or become stunted as the fungus interferes with the plant’s ability to absorb water. Though remember that this problem can occur in hot conditions, too, because moisture is evaporating from the leaves faster than the roots can take it up. So, you might have to double-check the reason behind it.

Root Rot – Root rot is one of the most noticeable symptoms of pythium, as the roots will turn brown or black and begin to smell. Since we can’t take out the roots every day to check if they have some issues, it is better to pay attention to other symptoms. If you notice multiple symptoms that we have mentioned above, then you can opt to check the roots.

Causes of Cannabis Pythium Disease

As we have already said above, this disease is caused by Pythium fungi, which thrive in moist and humid conditions. The fungus can spread or grow through contaminated soil, water, or other growing materials. Not only this, but Pythium can also spread through the air, making it easy to spread from one plant to another.

High levels of humidity, poor air circulation, and over-watering are all factors that can contribute to the growth of pythium in cannabis plants. If you know about the right growing conditions and materials to use in your plants, then you can easily prevent such diseases. Below we have listed a few factors that contribute to cannabis pythium infection:

  • Overwatering
  • Poorly drained soils
  • High humidity and moisture levels
  • Poor ventilation
  • Poor sanitation
  • Use of contaminated soil or grow media

Prevention and Treatment of Cannabis Pythium

Along with other problems, treating cannabis pythium requires proper management of the growing environment and good hygiene practices. You must know about proper growing techniques and how to prevent such issues from happening. There are many cannabis growing guides available on the internet that you can read to understand more about cannabis cultivation.

Though if you are worried that your plants might get infected with this disease or they already are, then you can follow some simple steps to get them back on track. Below we have mentioned a few tips that can help you in preventing and treating the problem:

Proper Ventilation – Ensure that the grow room or greenhouse has good air circulation to reduce humidity levels and prevent the growth of pythium.

Sterilize Growing Materials – Sterilize all growing materials, including soil and containers, to prevent the spread of pythium.

Avoid OverWatering – Overwatering can contribute to the growth of pythium, so it’s important to water plants only when necessary and to avoid overwatering.

Use Fungicides – Fungicides can help to prevent and treat pythium, but it’s important to choose a fungicide that is specifically formulated for use with cannabis plants.

Remove Infected Plants – If a plant is infected with pythium, it should be removed from the grow room or greenhouse to prevent the spread of the disease to other plants.

FAQs Related To Cannabis Pythium

Can Pythium Be Treated After It Has Infected The Plant?

Yes, just like every other plant disease, Pythium can be treated but only if you take action on time. We have already mentioned a few tips and tricks that can be followed to prevent and treat this disease.

It is better to avoid touching or consuming Pythium-infected plants and always wash your hands after treating them.

How Can I Prevent Pythium In My Cannabis Crop?

To prevent Pythium in your cannabis crop, you can use well-draining soil, avoid overwatering, increase air circulation, and use disease-resistant strains. You must also keep track of the growth and development of your plant, as this will allow you to identify the signs at an early stage, and you can start the treatment.

What Temperature Does Pythium Grow?

The optimal growth temperature for most Pythium species is between 25-30°C (77-86°F) but some can withstand temperatures up to 4°C. The survival temperature range of Pythium depends on specific strain and nutrient availability. But Pythium is most active at temperate below 20°C, and it cannot tolerate a temperature above 40°C.

What Are The Signs and Symptoms of Pythium?

Both nutrient deficiency and Pythium disease will show similar symptoms and signs because they both will prevent the roots of the plant from functioning properly. If you notice yellowing of the leaves, stunted growth of the plant, wilting, etc., then it means your plant has been infected with Pythium or some other diseases.
