We all know that dogs are capable of some remarkable things, they can lead the blind, aid police officers and provide therapy for sick patients. Well, the talents of the canine don't stop there! Did you know they can also detect Japanese knotweed?

A Start-Up Company in Ireland

Helga Heylen founded her start-up company back in 2018 and has been training dogs to detect Japanese knotweed with incredible accuracy. Heylen claims that one of her sniffer dogs is able to detect the Japanese knotweed rhizomes even if they haven't broken the surface of the soil yet!

Using their powerful noses, the dogs are able to identify the exact location of a developing knotweed problem. Heylen currently has three knotweed detecting dogs working for her, one is a purebred labrador and the others are labrador-beagle crosses. 

These amazing sniffer dogs can really transform the way that Japanese knotweed is detected and treated. Rhizomes as small as a fingernail can be laid dormant under the soil for a number of years before developing into a fully-fledged knotweed nightmare! If dogs can help commercial property developers, home and business owners to quickly find and treat the problem, it could prevent a huge amount of structural damage later down the line. 

How Do These Dogs Work?

Unlike humans, dogs don't need to be able to see the knotweed to know it's there! They have a keen sense of smell that can identify rhizomes several metres under the ground. They can quickly move through over-grown terrain and don't need bright lights to work. This means they can quickly survey abandoned areas of land that humans simply couldn't access on foot. 

Doggy Danger

While these dogs might sound like miracle workers to those of you with a knotweed problem, there are some people who do not feel so positively about them. While working in Belgium, one of Heylen's dogs was given poisoned food after it detected knotweed at the site of an upcoming commercial development. The discovery of the knotweed by the talented pooch delayed the development project, which was a source of frustration for investors. 

Since then, security for the dogs has been tightened to make sure nothing like this happens again. They sleep under security cameras and are kept indoors near to the handlers. Hopefully, they can continue to carry out their work unharmed from now on! Heylen said: "You know it's a good thing when it excites like-minded people, which is certainly the majority and really scares others".

If you have spotted Japanese knotweed on or near your property and are wondering if you need a licence to remove it – in short, no you don't.

The legal standing surrounding Japanese knotweed across the UK varies. In England and Wales, the primary legislation relating to knotweed is ‘Section 14(2) of the Wildlife and Countryside Act 1981’. In Scotland, this is still the predominant piece of legislation but in effect has been superseded by the changes which came into force with the ‘Wildlife and Natural Environment (Scotland) Act 2012’. The law surrounding the management and control of knotweed across the UK, however, is practically the same.

Japanese knotweed is categorised as an invasive species, and it is the responsibility of the owner of the land where it appears to prevent it from spreading into neighbouring properties or into the wild. The removal of Japanese knotweed must also be performed with extreme due care and attention due to the sensitivity regarding its ability to spread. Currently, there is no legal obligation to remove or treat knotweed, just as long as you’re not encouraging or allow it to grow.

Guidelines set out by the government state that anyone wanting to use chemicals to treat an infestation of knotweed must do the some or all of the following:

• Make sure anyone spraying holds a certificate of competence for herbicide use or works under the direct supervision of a certificate holder
  
  
• Carry out a Control of Substances Hazardous to Health assessment
  
  
• Get permission from Natural England if the area is protected, for example, sites of special scientific interest
  
  
• Get permission from the Environment Agency if the plants are near water

The use of pesticides and chemicals in treating Japanese knotweed is governed by ‘The Control of Pesticides Regulations 1986’ and required any person who uses a pesticide to take all reasonable precautions to protect the health of human beings, creatures and plants. Once knotweed has been treated with chemicals, it will have to be disposed of in the correct way. Off-site disposals fall under the ‘Environmental Protection Act 1990’, which states disposing of Japanese knotweed must be conducted by a licensed waste carrier as stated in ‘Waste Regulations 2011’ and disposed of within a licensed facility. Relevant transfer notes must be completed and stored. If knotweed has not been treated before off-side disposal and simply removed, then it is not classed as hazardous waste. If certain pesticides have been used, however, then the waste moves into the hazardous category requiring a consignment note as set out in the ‘Hazardous Waste Regulations 2005’.

In 2013, the UK government stated that any person that fails to control Japanese knotweed along with other invasive weed could receive an anti-social behaviour order. On-the-spot fines of £100 can also be issued, potentially rising to £2500 if prosecuted. Companies also face fines of up to £20,000 if prosecuted

Japanese knotweed is one of the most - if not the most - invasive plant in Britain. As its name suggests, Japanese knotweed is native to Japan, where it is known as “itadori”. One interpretation of this name is ‘remove pain’ which alludes to the plant’s painkilling properties and use in various medicines to treat a variety of ailments ranging from cardiovascular diseases, fungal infections and skin inflammations.

Knotweed can also be found in other parts of Asia, such as China, Taiwan, and areas of Korea. In Japan, knotweed grows freely on mountainsides, volcanoes, and open spaces, which is a little different compared to the UK. In Japan, knotweed has natural predators that come in the form of invertebrates, fungi, ash deposits from volcanoes, and an erratic climate. In Britain, however, there are no natural predators to limit the spread of knotweed.

The history of Japanese knotweed is not as simple as you may think. How did it get here in the first place? Why did it spread so vigorously? And why is it such a problem today? 

In this blog post, we take a deep dive into the history of Japanese knotweed to find some answers to the many questions surrounding this pesky plant.

A Welsh council’s decision to continue using a weed killer that has been linked causing cancer has been described as a ‘kick in the teeth for residents’.  

Torfaen council has decided to continue their use of a glyphosate-based weed killer on the invasive Japanese knotweed in a meeting this week, whilst continuing to monitor alternatives that are being developed. A motion to halt the use of the product and one to limit its use to preventing Japanese knotweed were both rejected before councillors voted to continue to continue using the glyphosate-based product.

A protest was organised out the council chamber in Pontypool ahead of the meeting, with campaigners urging council members not to vote for its continued use. In addition, around 700 people have signed a petition titled ‘stop spraying our towns with probable cancer-causing glyphosate’, which was presented to the council last year.

Councillor Fiona Cross who is a cabinet member for the environment said that there could be a ‘detrimental effect’ on the appearance of the county borough as well as structural issues if they were to stop using the weed killer without having a suitable alternative in place.

She also pointed out that the authority uses a low concentration substance which is endorsed by both the Welsh Government and European Union. Council leader Anthony Hunt backed up the previous statements saying the council must take a pragmatic approach but added that if a ‘better alternative’ was to become available, then the council ‘should look to use that.’

Independent councillor David Thomas, on the other hand, stated that the council should not take ‘unnecessary risks’ by using the weed killer and called for it to be scrapped. Councillor Elizabeth Haynes put forward a motion for the authority to stop using the product but an amended version was voted down. A second motion was proposed by Conservative councillor Huw Bevan, which called for the council to continue using the weed killer but not in ‘high public footfall’ areas.

Cllr Bevan said he understood there is ‘no other effective treatment’ for the invasive weed, but called for the authority to further limit the product’s use elsewhere. This motion was also rejected.

Campaigner Terry Banfield said the decision is a “total kick in the teeth for residents.”

A warning has been recently issued regarding a destructive ‘hybrid’ plant, known as Bohemian knotweed produced as a result of cross-fertilisation between Japanese knotweed and Giant knotweed.

The Property Care Association (PCA) says reports of the hybrid plants are on the rise. Also known as Hybrid knotweed, the plant could become a real concern if it gains a foothold nationally.

Dr Peter Fitzimons, group technical manager of the PCA’s Invasive Weed Control Group stated: “Bohemian knotweed, although less common, has been around for almost as long as the better-known Japanese knotweed, but is not always recognised.”

“As a result, it has remained largely below the radar, but the reason for concern is that these hybrid plants can be even more vigorous than the parent plants.”

“We also need to be alert as, in other parts of the world where Hybrid knotweed is more common, they are seeing signs of fertile seed production, known as backcrossing.”

“If so, this could be a major concern for the future as the existence of seed-producing hybrid knotweeds may enable these plants to spread even more rapidly.”

Listed under Schedule 9 of the Wildlife and Countryside Act, Japanese, Giant and Hybrid knotweed are all deemed as invasive and potentially destructive plants. They are steadily becoming more of a nuisance to home and business owners up and down the country because of their ability to spread quickly via their rhizome network.

Fitzsimons added that “since the PCA formed the Invasive Weed Control Group in 2012, we’ve always maintained the position that whilst this plant is disruptive around buildings it can be brought under control using established techniques and processes.”

“However, its presence can impact on the ability to gain a mortgage and on the development cost of land. More research is needed to see what the impact is of Bohemian knotweed, but for now, we should be aware of the issue.”

If you have spotted Bohemian, Giant or Japanese knotweed near your home, and like many homeowners in the UK are worried about the potential impact these invasive plants can have on your property. Then please do not risk it and get in touch with us here at Total Weed Control.
