The disease is the result of a dynamic relationship between an organism and the normal processes of the plant. The organism that causes the disease is referred to as the pathogen. Most plant diseases are caused by fungal or fungal-like organisms. However, they can also be caused by viral and bacterial organisms.

These factors are the signs and symptoms that the plant is experiencing as a result of the pathogen. A sign is physical evidence of the pathogen, it is the visible products or structures produced by the pathogen on or in the plant. Examples of a sign would be mushrooms, reproductive structures, as well as bacterial ooze.

Examples of symptoms include a change in colour, structure, and overall plant function. As well as being able to properly identify visual characteristics of the present disease, it is also important to know what type of disease it is. This will be helpful for determining the best approach for treatment and prevention.

Infectious diseases tend to be more difficult to control as they are caused by living organisms (bacteria, fungi, viruses, etc) and these organisms have the ability to spread. While non-infectious diseases are caused by non-living organisms and are often a result of unfavourable growing conditions such as extreme temperatures, light, water, nutrients, etc.

Fusarium wilt & root rot ( No visible signs of fusarium are typically present, it is usually the symptoms that the plant experience as a result of a disease that is used to ID Stunted growth Initially plants will wilt at the hottest part of the day and recover at night Leaves begin turning pale green/ yellow and will later wilt, wither, and die, dropping off progressively upward from the base of the stem The whole plant will eventually become pale green/yellow and begin to wilt Roots may become brown and begin decaying Vascular tissue on the plant will become discoloured often a red or brown colour Leaves will also curl and look like they are going to drop off, but they won’t The best “treatment” for fusarium is prevention.

3. Bud rot/ Grey mold ( Grey masses with a velvety appearance begin developing on the buds of the plant. flowers and leaves will have a collapsed and water-soaked appearance Brown lesions may become present on undeveloped flowers Stems and branches infected with grey mold will die back (stem cankers) There is currently no approved fungicide to combat botrytis, making prevention that much more important.

Make sure your plants are spaced properly to allow for adequate airflow. If bud rot is discovered the most effective form of treatment is to remove the affected parts of the plant. It is important to remember that while removing these pieces of flower not to let them come into contact with clean material.

Viruses simply cannot be controlled once they are transmitted. That’s why sanitation is key for controlling this virus. If you do discover an infected plant it should be removed immediately to stop the spread. Prevention is the most important part of keeping your plants disease-free. To be successful at preventing disease you will want to develop a disease management strategy.

Is the growing space regularly cleaned? Are the tools you are using cleaned between plants? Is it time to rotate the crop to a different variety?

At this point, the infection cannot be reversed but you can reduce spread and the potential of infecting other plants by Killing any pest in your grow space that could be spreading the disease, removing infected parts of the plant, fumigating between crops, completing the removal of an infected plant, and once again sanitation! Remove any dead organic material from your grow space.

In Soil Remediation with Cannabis, we saw that cannabis is a resilient plant, with the ability to draw up toxins from the soil and remediate contaminated land. Though often touted as a “superweed’ with healing pharmaceutical abilities and numerous industrial offerings, we must not forget that cannabis, at the end of the day, is still a plant.

Like human bodies that are constantly thwarting off pathogens, such as the common cold virus, plants are also under constant attack. In this article, we will look at five of the most common cannabis diseases that can threaten your plants, and also give some insight into how you can both prevent and treat them if they occur.
