While hemp is often considered as a low maintenance crop due to its higher resilience to pests and diseases, it can still be susceptible to mold concerns. Since hemp flowers inherently absorb moisture, it can become the prime target for mold. If your hemp crops experience any mold issues, it can rapidly damage your plants. For farmers in California interested in planting CBD seed for hemp cultivation, here’s what you need to know in order to prevent and treat mold.
Understanding the Role of Mold
Mold refers to the fungus that’s composed of countless microscopic spores that are transported throughout the air and lands on surfaces. Mold is everywhere you can imagine and almost impossible to eliminate completely. Its spores are fed by releasing enzymes that break down organic materials like hemp crops. While mold acts as a significant decomposer in the wild, it wreaks havoc among hemp crops. The key ingredients needed by mold are darkness, stagnant air, humidity, and moisture.
Making sure your farm is absent of these listed ingredients is the best way to help prevent mold from thriving in your farm.
Common Types of Hemp Mold In California
There are over 100,000 different types of mold but not all harmful to hemp– here are the common ones you’ll need to look out for when cultivating hemp:
- Gray mold: Gray mold finds weakened plants that have wounds or openings but can also target healthy plants as well. You’ll see gray-brown spots on wet hemp buds and yellow discoloration on stems. This type of mold will destroy the flowers of your crop, making your CBD hemp worthless.
- Powdery mildew: If you see fine white dust on your plants, chances are that you have powdery mildew. Hemp crops in hot, humid conditions with limited airflow are the most susceptible to this type of mild. You should be able to spot this type of mold on the foliage as well as yellow-to-brown ascomata.
- White mold: Dark brown lesions found on stems are an indicator of white mold. Stems that have these lesions can break easily and actually conceal mycelial growth.
- Sooty mold: Sooty mold produces a thin layer of soot throughout hemp leaves. While sooty mold won’t directly feed on your hemp since it eats common plant insects, it does disrupt photosynthesis and can stunt the overall health and growth of your plants.
- Fusarium: This is the most terrifying mold any farmer has to face– Fusarium can happen quite fast and can actually destroy your entire crop. It works by damaging the root system of your plants. By the time you notice the wilting leaves of your plant, it’s usually too late. If your crop endures a full-blown case of fusarium, there’s not much you can do. Hemp insurance can be a very valuable thing to have in these cases.
