Very little research exists on pests and diseases for hemp. That does not mean the plant is resistant, it only means that there is no proof. But here’s what we have noticed

In the first few seasons growers saw few problems with pests. As the hemp footprint increased, more pest impact was detected. European corn bore, yellow army worms, aphids, grasshoppers, and other pests are beginning to damage plants. For seed and CBD production, some of these pests either target the bud, causing bud rot, or leave the plant with contaminates from waste and infection.

Hemp is also susceptible to mold and mildew during the growing, drying, and storage stages of production. Many high-end growers recommend walking fields daily and removing infected flowers and mold from plants. Allowing mold to persist into harvest can cause contamination of more flowers as the plant goes into drying.

Actual damage to the end products may vary depending on the end use and buyer of the crop. Extractors and end users prefer a clean product – free from mold and other contaminants. In general, the cleaner the product, the more it is worth.
