Yesterday (6/27/19) Clemson’s Department of Pesticide Regulation (DPR) released a list of pesticides they are now allowing for use in hemp production. A PDF including a letter from DPR and the list of approved products can be accessed here: Approved Hemp Pesticides. Please read the letter from DPR before using any chemicals on the list. Additionally, it is recommended that growers speak with their processors to ensure using these chemicals will not result in any unacceptable residues.
Previously, growers were only allowed 25(b) products, which the EPA deems “minimum risk products”. These are products that do not have EPA registration numbers (mostly plant extract oils).
