Aquacide Environmental Weed Control

Aquacide® Thermodynamic Sterilization - Non-Chemical Destruction of Viruses, Bacteria, & Vegetation, on Contact Aquacide® - kills viruses, bacteria and weeds with superheated water!
Aquacide - kills pathogens and weeds with superheated water!



A virus is genetic material contained within an organic particle that invades living cells and uses their host's metabolic processes to produce a new generation of viral particles.

  • The virus is not a living organism, but a protein molecule (RNA) covered by a protective layer of lipid (fat), which, when absorbed by the cells of the ocular, nasal or buccal mucosa, changes their genetic code. (mutation) and convert them into aggressor and multiplier cells.
  • The virus is not a living organism like bacteria; you cannot kill what is not alive with antibiotics.
  • The virus is fragile however; protected only by a thin outer layer of lipid (fat).


It is essential that we remain diligent and control all possible direct human to human exposure pathways.

It is equally important that we control indirect transmission as well where the virus may pass from a person to a surface or object and from that surface or object to another person.

Preliminary reports suggest that COVID-19 can survive for up to 2-3 days on some surfaces. Location sterilization measures should be implemented and maintained to protect against any future viral transference threat.

One of the most accepted forms of microbial control is through the use of heat. In fact, the CDC recommend heat energy as the preferred method for sterilizing medical and surgical instruments.

The extreme heat energy contained in the Superheated water produced by the Aquacide® liquefies, oxidizes and destroys both the protective lipid layer of the virus as well as the protein molecule.

The ability for superheated water to flow around and envelope its target ensures coverage and heat uniformity in the most difficult, hard to reach locations and crevices.


The extreme temperature of superheated water sterilizes target surfaces and inactivates all resistant bacterial spores in addition to fungi, bacteria, and viruses.

Thermodynamics is the branch of physics that deals with the relationship between heat and other forms of energy. It describes how thermal energy is converted to and from other forms of energy and how it affects matter.

Sterilization refers to any process that eliminates, removes, kills, or deactivates all forms of life (in particular referring to microorganisms such as fungi, bacteria, viruses, spores, unicellular eukaryotic organisms such as Plasmodium, etc.) and other biological agents like prions present in a specific surface.

An Autoclave is a device that uses 121°C (250°F) + superheated steam under low pressure to effectively sterilize medical instruments, non-chemically.

The Aquacide® is a device that uses 125°C (260°F) + superheated water under low pressure to effectively sterilize large areas and surfaces, non-chemically.

Aquacide® Thermodynamic Sterilization is used in high traffic, public pedestrian locations to control possible contact and transmission of any viral or bacterial contamination

To kill a biological entity as complex and structured as a plant or weed without the use of chemicals, you need a great deal of heat and that heat must also be safe. Open flame and combustibles are not practical for these reasons.

Steam can be heated but cools quickly. Steam also has a hot spot rather than enveloping a target and evenly distributing heat. High pressure is also a concern.

Water may be superheated, but usually only in a controlled environment as it converts from a liquid to a gas at 100°C (212°F). Saturated vapor pressure rises with an increase in water vapor as well!

Aquacide® is an innovative breakthrough in superheated water delivery. The proprietary process allows incredible levels of heat to be transferred to the water, for that now superheated water not to gain significant pressure, and for that water to remain in a liquid state at the point of application.

The extreme temperature of the superheated water immediately destroys the cellular structure of vegetation, killing the plant or weed on contact.

The Aquacide® process of vegetation control provides a safe and dependable alternative to chemical herbicides used in:

  • Parks
  • Golf Courses
  • Playgrounds
  • Public Areas
  • Greenhouses
  • Waterways
  • Sports Facilities/Bleachers
  • Tree & Shrub Beds
  • Interlock, Unit & Cobblestone
  • Roadways & Shoulders
  • Sports Fields
  • Expansion & Control Joints
  • Gum & Graffiti Removal
  • Utility Vaults & Substations


Aquacide® Thermodynamic Sterilization uses only water, superheated in excess of 125°C (260°F), and is applied under low pressure while still in a liquid state.


  • Superheated water under low pressure ensures maximum coverage with minimum blow-back or scatter
  • Destroys viruses or bacteria on contact
  • Uses superheated water to sterilize - no toxic chemicals or combustibles
  • No harmful drift, direct or indirect exposure concerns
  • Safe for people and wildlife
  • Can be used near bodies of water
  • Application unaffected by weather - can be done in both wind and rain
  • Easy to operate - one person operation
  • No groundwater, storm water, or environmental contamination concerns
  • Elimination of the hazards and costs associated with handling, licensing, posting, transporting and storing of chemicals
  • Multifunctional - bacterial, viral and vegetation management
  • Portable and compact - can be mounted on existing equipment
