SelectrocideÂ? from Selective Micro Technologies Â? Algaecide, Fungicide, Virucide Approved by EPA for Use in Plant Propagation, Food Preparation, Water Storage & Delivery

Selective Micro Technologies announced today that The United States Environmental Protection Agency (EPA) has conditionally approved Selectrocide™, a chlorine dioxide product as a disinfectant, sanitizer, and algaecide for applications in the horticulture and food processing industries. Announcement of EPA approval follows only two weeks after Selective Micro Technologies announced an allowance by the Food and Drug Administration (FDA) for to use its chlorine dioxide product to wash fruits and vegetables.

Selectrocide™ produces greater than 99% pure chlorine dioxide by simply submersing the product in water. The resulting chlorine dioxide and water solution can be used to kill disease-bearing bacteria, fungi and algae. For the horticulture and food industries, chlorine dioxide has not been available to clean plants, food and equipment because chlorine dioxide could not be produced on site without significant chemical residuals. Selectrocide™ makes it possible for the first time to generate specific concentrations of chlorine dioxide at the point of use with very low residuals, neutral pH, using only water with no capital equipment.

“EPA approval allows us to sell chlorine dioxide into hundreds of applications in dozens of industries to reduce levels of bacteria, yeast, and algae. Selectrocide™ has demonstrated in field trials the ability to extend the shelf life of processed food while maintaining taste and presentation. In horticulture, Selectrocide™ has reduced the propagation loss in greenhouses,” said John Warner, CEO, Selective Micro Technologies. “We don’t believe there is a biocide as effective in the world.”


A complete list of approved applications for Selectrocide™ can be found on the Selective Micro Technologies web site at http://www.selectivemicro.com. Below are the expected initial uses for Selective Micro Clean in the Horticulture and Food/Beverage industries:


·    Bacteria, algae and fungi control on rooted or un-rooted cuttings and cut flowers, seed-bed soil and planting cubes

·    Treats, controls, inhibits algae and fungi in greenhouse irrigation lines, filter systems, walls, ceilings, floors


·    Hard, non-porous surfaces such as tanks, transfer lines and other food processing equipment, floors, walls, ceilings in poultry, fish and meat plants, and in restaurants, dairies, beverage and bottling plants, breweries, wineries, commissaries.

·    Water system and beverage lines, holding tanks and other equipment used in fountain drink or other beverage preparation, storage, transfer and dispensing operations.

·    Boat, RV, Aircraft water lines, storage tanks and potable water applications.

·    Medical and dental offices, laboratories, hospitals and clinics that use water storage tanks, transfer lines and filter systems.


·    Boat, RV wastewater tanks and lines

·    Fountain drink or other drink preparation, storage, transfer and dispensing lines, equipment

·    Coolers, thermoses, plastic water bottles and other water dispensing systems


·    Reduces algae, viruses, bacteria, yeast and mold on food and plant facilities and preparation surfaces

·    Reduces bacteria, yeast and mold on fresh cut food

·    Extends shelf-life of food – produce lasts longer, looks better, tastes better

·    One product for all antimicrobial requirements in both horticulture and food preparation settings


Selective Micro®’s Selectrocide™ is sold as sachets with reactants contained within proprietary membrane materials. The sachets are immersed into water, producing a greater than 99% pure chlorine dioxide solution, at neutral pH, with virtually no unwanted by-products. Selectrocide™ makes it possible to generate chlorine dioxide at specific concentrations (from 1 part per million (ppm) to 500 ppm) in specified time periods.

According to the Annual Research Report, Southwest Research Institute, San Antonio, TX, 1996, “Chlorine dioxide is a powerful biocide that can kill fungus, bacteria, and viruses at levels of 0.1 to 1 part per million in contact times of a few minutes.” The low levels of chlorine dioxide required to kill microorganisms is in stark contrast to other antimicrobials that require parts per million ranging from hundreds to hundreds of thousands of parts per million in order to be effective. Such high concentrations make the competitive products highly corrosive, dangerous to handle and difficult to rinse. Being highly effective at low concentrations means Selectrocide™ rinses off food and equipment easily, and has no adverse effect on food flavor.


Chlorine dioxide is a highly unstable gas and cannot be transported in containers or cylinders, so its potential over the last 50 years has gone untapped in many applications. For the first time ever, greater than 99% pure chlorine dioxide can easily be produced at the point of use without harmful residual chemicals, high capital expense or complex generation-plant assembly.

Formed in 1999, Selective Micro Technologies is a private company based in Beverly, Massachusetts. Combining sophisticated science with innovative product design, Selective Micro® has invented a proprietary delivery system that controls the rate and efficiency of gas-producing reactions. Our competitive advantage is the ability to generate specific concentrations of chlorine dioxide with very low chemical residuals and neutral pH – at the point-of-use, using only water, without capital equipment. The Company holds two US patents, and has several other patent applications pending in the US and abroad.
