When Things Go Wrong
First, we start with a discussion of pests. More than 300 pest species have been identified on cannabis plants; even those typically not considered “devastating” to a cannabis grow can still vector diseases such as pathogenic fungus, bacteria, and viruses. To prevent and treat pest problems, cannabis growers need to understand the life cycle of common pests and the environments in which they thrive. In this course, we review the most common known pests that affect cannabis and discuss some general treatment options.
Then, we move on to pathogens that lead to disease in cannabis plants. We identify some common pathogens found in cannabis, along with the diseases they can cause and the symptoms of those diseases. Then, we explore the conditions which must be present for a disease to emerge and offer strategies for controlling pathogens and disease in a cannabis cultivation operation.
From there, we move on to prevention, treatment, and IPM. We present strategies for preventing pest and pathogen infestation, such as sanitation, environmental controls, cultivating beneficial microorganisms, companion planting, and the introduction of beneficial predators. We then review some of the treatments available to control a pest or pathogen infestation and discuss how to do so safely and efficiently. We then introduce the concept of integrated pest management and provide resources for learning more about the practice.
Finally, we discuss nutrient disorders. The delivery of essential nutrients through fertilization is an essential factor in successful cannabis production. Under-fertilization can cause nutrient deficiency, whereas over-fertilization can lead to salt accumulation in the root zone and cause “nutrient lockout.” Both can have a negative impact on yield. In this class, we learn more about how nutrients travel through the plant, which will help us better understand how nutrient disorders occur and how to identify them. We then introduce some of the most common cannabis nutrient disorders and all the complexities that go along with diagnosing, preventing, and responding to nutrient issues in your cannabis plants.
About Our Self-Paced Electives
Self-Paced Programs are asynchronous, meaning you may log on and complete the courses anytime, anywhere that is convenient for you. You can access the course online as soon as you enroll.
Programs consist of reading materials developed by our expert faculty, accompanied by videos, texts, and recommended resources.
All self-paced programs include live links to a wealth of information that allow you to dig deeper into subjects of particular interest.
Each program also includes a Virtual Video and Resource Library with corresponding recorded lectures from our faculty.
Self-paced students receive access to virtual field trips, grow labs, the Oaksterdam Alumni Network, and more.
Completion of all requirements results in OU certification.
When Things Go Wrong
Cannabis plants are susceptible to a wide variety of pests and pathogens that can devastate your grow, and vector diseases such as pathogenic fungus, bacteria, and viroids. This class offers an understanding of threats as well as ways to prevent and treat them with Integrated Pest Management and nutrient balancing.
