6/30/2023 – Update: the links included in the article below contain current information.

3/10/2021 – Yesterday, the EPA released a long list of pesticides that they have cleared for use on hemp: Pesticide Products Registered for Use on Hemp (This page is no longer available). This is good news for our hemp growers, but before you can legally use these products in North Carolina, they must be registered with the state. I asked Lee Davis, pesticide registration manager with N.C. Department of Agriculture and Consumer Services (NCDA&CS), to provide us with some guidance on this, and this is what he shared:

Growers can go to Kelly Solutions to search for products registered in North Carolina. There are several ways to search including using the EPA registration number. You can plug in the registration number given on the EPA list to see if North Carolina has any product(s) registered with that EPA registration number. Keep in mind that a single EPA registration number can be associated with several brand names, so you will need to review the container labels to make sure hemp is covered on the label on the product you are interested in.

Edit added 5/1/2024: NC growers can also consult the NC Agricultural Chemicals Manual

He pointed out that the information about minimum risk pesticides that I wrote about in an August 2018 News Update remains the same. I have copied that for you here:

There are some minimum risk pesticides that do not have to be registered with the EPA and are regulated on a state level. Here is a link to the EPA Minimum Risk Pesticide page. A company can apply to register a minimum risk pesticide for use on industrial hemp within a particular state. In August 2018, the N.C. Department of Agriculture and Consumer Services Pesticide Division provided us with this guidance on minimum risk pesticides approved for use on industrial hemp in North Carolina: 25b pesticides that are labeled for industrial hemp can be used in North Carolina. In addition, 25b pesticides labeled broadly enough that industrial hemp can be considered to be covered by the label can also be used in North Carolina. Since some of the by-products of industrial hemp may end up in consumable products, the ingredients in the 25b products must be approved for application to food crops and the 25b products must be labeled for application to food crops. But, keep in mind, if there is language on the label that would in some way prohibit application to industrial hemp, the label language supersedes our comments above. The EPA also dictates which inert ingredients can be in the 25b products and not all of them are approved for food use. Here is the link to the minimum risk pesticide info. Click on “Condition 2” to see links to the inert information. Growers should double-check with the manufacturers of the 25b products they are interested to confirm that all the ingredients are approved for food use. Pesticide labels can change over time which can make a once acceptable product no longer usable. Also, acceptable new products may be introduced at any time. Due to this, NCDA&CS will not be developing a list of products to choose from. We hope the information above will help you with your selection of appropriate pesticides for use on industrial hemp in North Carolina.
