TOMI Environmental Solutions Receives EPA Registration Expanding SteraMist® for Use in Post-Harvest Agricultural Food Safety Including Cannabis and Hemp Cultivation

New EPA Reg. No. 90150-4 authorizes SteraMist^® (BIT^®) – AgriMist for use up to and including the day of harvest, opening the door to indoor, greenhouse and hydroponic cannabis and hemp operations, along with post-harvest raw agricultural commodity treatment.

FREDERICK, Md., Aug. 03, 2026 (GLOBE NEWSWIRE) -- TOMI Environmental Solutions, Inc. (NASDAQ: TOMZ), a global leader in disinfection and decontamination solutions, today announced that the U.S. Environmental Protection Agency (EPA) has granted a new unconditional registration for SteraMist^® (BIT^®) – AgriMist (EPA Reg. No. 90150-4), the culmination of a multi-year registration process, expanding the product's labeled use sites to include post-harvest food safety applications, cannabis and hemp cultivation, and greenhouse and hydroponic agriculture.

The new registration allows TOMI's patented SteraMist ionized Hydrogen Peroxide (iHP) technology to be applied directly to a wide range of indoor-grown plants, such as hemp, tobacco, ornamentals, and specialty and medicinal crops for the prevention, control and suppression of common plant pathogens such as powdery mildew, downy mildew, Botrytis, Fusarium and Pythium rot. Notably, the label permits application up to and including the day of harvest, a distinction cultivators have identified as a key operational advantage.

The registration also extends to post-harvest treatment of raw agricultural commodities (RACs), giving food safety and packing operations a tool to help reduce cross-contamination between harvest and shipment. Because of the low hydrogen peroxide, SteraMist's sole active ingredient, which breaks down naturally into oxygen and humidity, treated surfaces require no rinsing or wiping after application.

“This registration expands what SteraMist can do for two of the fastest-growing segments we serve,” said Dr. Halden Shane, CEO of TOMI Environmental Solutions. “We've known for years that SteraMist was capable of this, now the EPA has confirmed it. We've been planning and waiting for this for several years, and it is incredibly rewarding to see it come to fruition. The avocado industry will be thrilled along with cannabis, hemp cultivators, and food safety operators. Everyone needs pathogen control that's rigorous enough to meet EPA standards and simple enough to fit into daily operations. With this label, we offer a technology that works up to the day of harvest, leaves no residue, and requires no rinsing or downtime.”

The expanded label positions SteraMist to serve growers and processors across a range of controlled environment agriculture settings, including greenhouses, indoor cultivation facilities, hydroponic operations, and mushroom production, as well as cut flower and nursery propagation applications covered under the same registration.
