DART™

The tried and tested DART™ method (Dual Action Residential Treatment) from Environet is the most cost-effective combination removal & treatment solution for Japanese knotweed on residential properties.

 

Environet has developed DART™, a method that combines root/rhizome removal with herbicide treatment. By removing the bulk of the crowns and rhizome system we massively reduce the plant’s vigour and stimulate growth of any small pieces of remaining rhizome that are then killed with effective herbicide treatment in the summer months. Less expensive than full excavation and quicker than herbicide, it gives you the best of both worlds.

 

DART™ can be carried out at any time of year, but the root/rhizome removal element is best carried out in the winter months, usually taking just a few days. The added benefit being that disruption does not occur in Spring, Summer or Autumn when you most want to enjoy your garden. The follow-up herbicide visits have minimal impact on you and your garden.

 

DART™ is offered with our insurance backed guarantee underwritten by an “AA-” rated insurer for up to 10 years. Should regrowth be experienced, further treatment is carried out at no extra cost.

Resi-Dig-Out™

With Environet’s unique Resi-Dig-Out™ method a property can be knotweed free in a matter of days at any time of year.

Where future works that involve disturbing the ground e.g. extensions or landscaping are planned, Resi-Dig-Out™ is the recommended method.

The Environet Resi-Dig-Out™ method has been developed for residential properties from our patented Xtract™ method. Knotweed infested soil is excavated and the viable rhizome is separated from the soil. The rhizome is removed from the property in accordance with Environmental Protection Act 1990 requirements and the excavated soil is back-filled into the hole.

It can be completed in a matter of days, at any time of the year and is much cheaper than Dig & Dump.

 

Resi-Dig-Out™ is proving to be the only realistic option where previous botched attempts have been made. Where rhizome dormancy has been induced, it’s not possible to successfully kill the rhizome system with herbicide, as it doesn’t have a sizeable leaf area. Physical removal is therefore the only practical option, unless you are prepared for the knotweed to be treated for many years.

Resi-Dig-Outs™ are offered with our insurance backed guarantee underwritten by an “AA-” rated insurer for up to 10 years. Should regrowth be experienced, further treatment would be carried out under the guarantee at no extra cost

What does Japanese knotweed look like?

Japanese knotweed herbicide treatment

Herbicide treatment is a popular control method because it has the advantage of being relatively low cost, and is effective if done correctly.
