The Organic Weed Killing Machines/Applicator Heads.

The 8 Hidden Costs of Chemical Weed Control

Chemical weed killing may seem cost effective in the short-term, but we’ve identified the following 8 hidden costs that you don’t experience with organic weed control.

1. Herbicide Resistance

Repeated applications of herbicides over many years has resulted in the evolution of many resistant species. This results in increased application rates and mixing of chemicals, which further damages surrounding ecosystems and increases costs. With our saturated steam weeders the weeds become more susceptible to killing and reduces treatment frequency.

2. Employee Exposure

All chemical weed killers are toxins. Repeated employee exposure to known toxins drives up health and safety requirements, certification and record keeping costs. Thermal technology removes toxicology risks associated with chemical weed control products, particularly for horticultural and conservation workers.

3. Off-target Damage

Chemical weed killers sprayed in even light breezes can result in overspraying and off-target damage to desirable vegetation and horticultural crops. Chemical weed killers often release vapours which can cause sickness in chemically-sensitive people. These off-target effects can lead potential litigation.

4. Tarnished Public Image

There is now widespread public knowledge about the hazard to human health of chemical weed killing. Chemical spraying by organisations will lead to a tarnishing of their public image and undermines their environment, safety and sustainability commitments.

5. Public Safety

Application of chemical weed killers, according to label, requires restriction of access to treated areas for a number of hours. This signage poses significant operational costs. Failure to restrict access can expose the public to ‘probable carcinogens’ and can lead to potential litigation.

6. Storm and Potable Water Contamination

Chemical weed killers translocate easily from paved surfaces, through soil profiles and can contaminate ground waters, streams, creeks and estuaries. Removing chemicals from drinking water sources creates enormous expenses.

7. Habitat, Ecosystem & Livestock Threat

Most commonly used weed killers have the potential to contaminate habitats of sensitive populations of endangered species such as frogs, bee’s and butterfly’s which are essential to healthy ecosystems. Chemical weed control that has the potential to contaminate fodder and water sources becomes a threat to livestock.

8. Soil Biology

The most commonly used weed killers are Glyphosate based. Glyphosate is a patented anti-biotic and chelator which has been shown to kill soil microbes and bind nutrients. This creates additional costs in soil remediation and fertilising.

A Few Words From Our Customers

Fromart Cheese

“Have used the Weedtechnics machine for a few weeks now. Must say: LOVE IT. weed management without a bad feeling, without affecting the environment, leaving the waterways clean for our saratoga fish, safe around the cheese factory and all farm animals. Well done Jeremy & team!”

Christian Nobel

University of Colorado Boulder

“My team at the University of Colorado was one of the first in the U.S. to use Weedtechnics steam equipment and I would be happy to provide relevant information about our success to any interested parties. We regularly do demos for area universities, cities, and school districts and talk with concerned parents around the country. Thanks, David”

Byron Shire Council

“The purchase of new steam weeding machine form Weedtechnics was great news for local residents who are concerned about the use of chemicals. We are using the steam weeder in children playground, retail areas of our towns and villages and other popular spaces such as picnic areas. The SW machine is highly effective at killing weeds.”
