Environmental Protection Agency (EPA) finalized a rule to include poly-d-glucosamine in
its list of exemptions for the lowest risk pesticides.
Chitosan is a natural substance
found in crustaceans, fungi, and insect exoskeletons.
The EPA specifies that the list also includes chitosan salts formed when mixed with acids that can be used as active or inert ingredients in the lowest risk pesticide products
.
The purpose of the exemption list is to eliminate the need
for agencies to spend significant resources regulating products that pose the lowest risk to human health and the environment.
Products that contain only active and inert ingredients that are exempt and meet the requirements of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) will no longer be subject to
FIFRA standard registration requirements.
About a decade
has passed since the first substance was added to the list of ingredients eligible for the minimum risk pesticide exemption.
Chitosan, as a fungicide, antimicrobial agent and plant growth regulator, is currently registered with the EPA under FIFRA supervision to improve the ability
of plants to resist fungal infections.
At present, chitosan is widely used in non-pesticide applications and has been used
in many industries such as textile, cosmetics, beverage processing and water treatment.

On October 10, 2018, EPA received a petition from Tidal Vision Products to include chitosan on the list
of exempt active ingredients for the lowest risk pesticide products.
In November 2020, the EPA sought public comment
on the proposed rule to add chitosan to the list of active ingredients eligible for exemptions.
In November 2021, the EPA asked applicants to provide more information
about chitosan salts and their potential impact on the environment.
Accordingly, the EPA received two aquatic toxicity reports, which were made available to the public for comment
in May 2022 through a data availability notification.

After reviewing the latest theoretical science, comments on proposed rules, and data availability notifications, EPA now adds chitosan to its list
of active ingredients that qualify for EPA's minimum risk pesticide exemptions.
The agency's analysis of available data shows that chitosan and chitosan salts have low toxicity to human health and have not identified any worrisome environmental risks
.
In light of this final rule, chitosan products will no longer need to be registered
under FIFRA supervision.
The EPA estimates that this action will initially save registrants and manufacturers of chitosan-containing pesticide products up to $116,000 and thereafter about $3,400 annually
