Guy's blog Glyphosate

Guy when you say "has fairly clear evidence of hurting insects and less clear evidence it may be carcinogenic." What evidence?When making the decision to ban Glyphosate, why did you believe the alternatives suggested would work? How was it a surprise that they didn't. Any competent, knowledgeable gardener could have told you they wouldn't.Acid formulas and hot foam or steam are "mechanical" systems for removing weeds. They kill the top growth of plants by burning them. Glyphosate is  "systemic". It is absorbed into the plant and down into the roots, it stops cell reproduction, so as old cells die new ones aren't produced and the plant dies.Burning the top of the plant away will only kill plants with a weak root structure that doesn't store energy; annuals and recently developed perennial and trees. Perennials have evolved to store energy in their  roots. They die back in winter and then re grow in spring, so can recover from having their leaves burned off. Trees, once they have put on some growth, will recover from having leaves burned. This is well known so the most basic enquiries would have enabled you to understand that.We are going through a period of rejecting science. The anti vax movement being another example. I don't believe you have any evidence that Glyphosate harms insects any more than you had evidence that alternative methods of killing weeds would work.That people reject science in favour of what people who are not scientists say is regrettable, but you were a Council Cabinet member making a decision that has cost, I believe, in excess of £1 million in revenue, made pavements unsafe and left an expensive legacy of capital repairs needed to fix roads and pavements damaged by roots and being stabbed at with hoes.As a Local Authority you have a public body, The Health & Safety Executive (HSE) to advise you on managing risks. The HSE says that Glyphosate is safe for people and the environment.  In rejecting your own advisers advice you have cost the Council a huge amount of money. You have helped spread disinformation causing concern in the public by repeating assertions that have no basis, just like the anti vax movement. How do yo justify that?

You are peddling an untruth.  Look at the Science and look at the number of court cases concerning Monsanto, new owner Bayer and glyphosate and the arguments over its use.Yes, Ealing does spray and the weeds are coming straight up again. I got such a mouthful of chemical names when I questioned the operatives when I was in the midst of a family crisis that I never really followed it up.  They did say that they spray three times a year and they have to choose the time and weather carefully.  I find it interesting which plants don't seem to be bothered by it.  There are some plants that haven't died back at all and there are new seedlings growing almost immediately.  Of course they become immune to it and there really isn't any point to it if they don't clean or brush the pavements or gutters.  All the dead heads of the spring flowering trees (often so small they are actually unnoticeable on the trees - especially if you don't look) are still lying like a mat of seedling compost on the pavements and in the gutters. Pointless poisoning of us all.  It's in breast milk and urine.  It's known to be dangerous to insects, fish and animals.  How stupid are we that we think that just because consequences aren't immediately bad for us that they aren't there?  What legacy are we leaving for our children in their lives?The gutters can't be cleaned because of the numbers of cars permanently parked in the streets and the inability of Council and/or Contractor to organise the removal temporarily or permanently to enable this.I have heard from a friend in Brent that they have the same problem as in Chiswick where they have had what seems like a dumped or abandoned untaxed car in their road for months and have been unable to get any action from Council or Police.  It appears there are a tremendous number of cars that are  using the roads and cluttering them up which shouldn't be with no tax or insurance let alone the number of people driving them without having a valid driving licence.  What a mess! https://ecologycenter.org/factsheets/so-whats-the-problem-with-roundup/

I think we all agree that front gardens should not be allowed to be totally covered in non-porous surfaces and paved to the detrimental loss of any planting. People often think that pots are the answer but they can be harder to maintain than a few flowering shrubs.  That Councils should somehow have the time, money and personnel to chase after and prosecute all residents and/or owners and keep on top of prosecuting those who have paved over their front gardens for parking is highly unlikely.  There are lots of things that we would like Councils to do but it seems that nobody or not enough people want to pay enough taxes to do this.Until or unless our drainage system in London is better designed and managed it will be very hard and expensive to succeed in sorting out water pollution although it can be greatly ameliorated by separating rainwater using water butts (years ago Councils and Thames Water offered reduced price ones) but no-one seems to have  the money or inclination now - or maybe the increase in water metering will help as we become more water stressed and more aware that we can suffer flash flooding as well as water shortages. There used to be something in the regulations on Council websites but somehow that seems to have disappeared about how much paving of any garden you are allowed.  Perhaps that was part of the Governmental burning of the regulations that caused all the problems with unregulated and unchecked planning, building, cladding and out of date and less clear Building Regulations in England compared to Scotland. Pesticide means something that kills pests and is a greater umbrella term for herbicides, fungicides, insecticides etc.

It really amazes me that there has been so much criticism of the change in policy to permit Glyphosate usage in Hounslow which somewhat has overlooked the damage to our insect life and efforts at supporting biodiversity by the failure of Hounslow to take action against the loss of so many gardens to allow for car parking.Apart from the danger that could be caused to services under our footpaths by driving across them without a properly constructed crossover, which has to be carried out by the Highways Authority - L.B. Hounslow, there is the question of concreting or paving over the garden to provide a hardstanding for the vehicle.Of course what should be happening is that permeable surfaces are installed to allow for water to soak away, but if a council does not enforce the Highways Act covering the illegal driving over a footpath - then neither can they ensure that all gardens used for parking have a permeable surface. Hounslow has done no such enforcement/prosecutions for driving over footpaths since 2022, and quite possibly prior to that, according to an FoI. So as well as losing any grassed, planted areas that provide support for invertebrates and many insects, like bees and butterflies, neither is water conservation a consideration. Yet, Hounslow has installed 'rain gardens', what is the point of spending money doing that - yet, at the same time allow gardens to disappear under concrete?Why aren't the crop of 'weeding warriors' up in arms over this? Loss of habitat is one of the biggest threats, and if you added up all those small plots lost it would probably be a shocking amount. It should be possible for both parking, where necessary, and sustaining a habitat promoting biodiversity in an urban area to go side by side, but it would require Hounslow to care and start looking at the problem and enforce where necessary. This could also bring much needed money in to council coffers with the vehicle construction works needing to be carried out by them as the local Highways Authority.

Correlation isn't causation. Pesticides includes insecticides which are clearly damaging to insects.  Glyphosate is a herbicide.PAN who you reference is a small lobbying Charity that carries out no research.If we are to address the serious environmental issues we face we need to follow science and evidence. I and others have increased the number of insects and birds at Dukes Meadows by planting trees, hedges and meadows. 15 years ago on the advice pf local naturalist Mick Massie we filled the old paddling pools with gravel, donated by Barret Homes and planted wildflowers. Yesterday when I was there I saw grasshoppers and butterflies. Mick surveyed recently and found a rare wasp. Vanessa, with other volunteers were responsibly for the transformation of Northcote Rec into Northcote Nature Reserve, through a project that created a backwater and introduced plants and management to promote bio diversity. She volunteers on the project. The funding has run out for the Borough Ecologist and the Council is seeking funding. One Ecologist for a Borough the size of Hounslow is a thin resource. Hounslow owns so much land the opportunity to adjust management, informed by someone with knowledge to enhance bio diversity, is huge.In years to come when future generations look back in dismay and disbelief, one of the many tragedies they'll reflect on his how well meaning people, rather than lobby for things that would actually make a difference lobbied to have huge amounts of money spent to ban something that wasn't causing any harm and could actually be used to increase bio diversity. By for example removing monocultures of alien invasive species.My main wish would be that policy is driven by achieving outcomes, that are based on clear research and evidence, not pointless virtue signalling activity.

You need to relook at the evidence concerning the use of Roundup and Glyphosate on insects because you are not up to date.There is a very big problem with the reduction and lack of insects.  Years ago we used to have the wash the car windscreen after travelling down the motorway but today hardly any insects get squashed on the number plates or windscreen.Three friends who kept bees have lost them in recent years.  This could have been other pesticides being used but could also be glyphosate which science shows causes problems to bees.  Chemicals are causing problems including upsetting bees' sense of direction so that they are not finding their way back to hives but that isn't all.There are many reasons for a loss of insects and it can also include the way that hedges and shrubs are now cut to suit a timetable created by someone's diary or just the look of them rather than being pruned to suit the wildlife that relies on them for food and shelter or to lay their eggs on and the best time to prune each individual plant.  Growing so many plants just for their foliage also does not help.  Weather also causes problems as does this idea that all migrant wild flowers and garden escapes need to be treated so uncharitably and killed off when many of them are not a threat at all to pavements, walls or anything else.The Environment Agency has stipulated that street sweepings of leaves ie from pavements are not suitable for composting. All the chemicals that are included in those sweepings contribute towards that.  There have been calls for years for us to reduce the chemicals that we use because of the damage that we are doing.  The spin and publicity to use them just increases as this is big business.  So does the heavy professional lobbying of those committee members who have to vote on whether or not to agree to extend any certification for use of glyphosate.https://www.pan-europe.info/blog/european-parliament-crucial-dialogue-protecting-bees-and-bugs-pesticides

Dear, dear Vanessa. If you're accusingme of thinking I know better, read what I have actually said, which in summary I don't know.I made no decision to stop using Glyphosate. I inherited a decision taken by someone else (don't really know who).I stayed with the policy on Glyphosate whilst I was on cabinet, despite a lot of hysteria pointed at me saying the streets a re a disgrace and a person in a £4M house in Chiswick teling me he was living in a toilet. (Yes, I quote).We stayed with that despite the criticism and various attempts to use alternative methods, none of which really worked.After it had nothing to do with me it was brought to the Parks Friends and Salamn Shaheen said he would do a scientific study. I pointed out that at least 100 such studies had taken place in theUSA with no solid conclusion . Same in the EU.I just looked at the EU situsation and find:"Will the carcinogenicity study carried out by the Ramazzini Institute as part of their Global Glyphosate Study (GGS) be examined by EFSA and ECHA?The Commission is aware of the publication of 10 June 2025 in the journal Environmental Health of some of the results of a study on glyphosate undertaken by the Ramazzini Institute as part of their Global Glyphosate Study (GGS).The Commission has mandated the European Chemicals Agency (ECHA) and the European Food Safety Authority (EFSA) to ask the study authors to provide all raw data without delay, and when the data will be received, to conduct a robust and thorough scientific evaluation as to whether the new information, considered alongside all other available data, changes their previous conclusions concerning the hazard (ECHA) or risk assessment (EFSA) conducted for glyphosate.This work will be carried out based on the relevant procedures of the agencies.ECHA already concluded two times (in 2017 and 2022) that based on the available information, including animal data and human epidemiological data, and using a weight of evidence approach, no classification for carcinogenicity is warranted for glyphosate. Therefore the new information by itself does not immediately call into question the outcomes of the previous reviews.If, in the light of a review of the new information, ECHA or EFSA would confirm that glyphosate does no longer meet the approval criteria in Regulation (EC) No 1107/2009 or indicate that the conditions of approval should be amended, the Commission will act immediately to amend or withdraw the approval, as appropriate."The EU are still on the fence and really, so am I. It is no longer something I have any council responsibility for and I am not a scientist. Perhaps Kathleen is, as she is passionately in favour of Glyphosate.I am an old socialist and by nature suspicious of research financed by a large multimnational, just as I was of Philip Morris and similar in the 70s. Because I carried on smoking for far too long I have an incurable, but seemingly manageable lung disease. Makes me cautious. If I had been in favour of a quiet life I would have reintruduced Glphosate when I was a Cabinet member, but I held on because we could contain the problem and I didn't think it was worth the risk to pollinators and possibly humans to reintroduce Glyphosate. At best, it's safety is unclear.The new cabinet has made a different decision and I don't demur from that, because I am not fanatical about it and I amguided by people who are actually expert.

I am perfectly aware that putting words into capitals is considered shouting on the internet but sometimes it is necessary because there are people who just do not listen and many people nowadays are most certainly pretty much incapable of reading anything let alone instructions which need to be carefully followed!You really need to do more research and take more care than just accepting what the HSE etc say in order to put ticks into your boxes.  You need to look at the bigger picture. From what you say you obviously have not even looked at any scientific papers.Yes, the Council tried doing something else so have many Councils.  It works best with residents co-operation.  It does tend to mean that more people are needed. It would be good employment and a learning experience for many people but they would have to be managed which is something you can't just do that from a spreadsheet.  I don't know how many other things the Council has tried.  We tend not to be told everything that is happening.  We find out later when the chickens come home to roost in this very politically polarised world.However, the greatest damage caused to pavements is definitely by VEHICLES driving over them, cracking paving stones and dislodging kerbstones and creating spaces for self-seeding plants to grow and not by the plants themselves. I've seen a plant of the dandelion family growing in its own personal circular hole in a paving stone made by the unprotected end of a scaffolding pole.  Councils and residents should be held more to account for following up on and making good the damage that is done by BUILDING works.  Buy cheap and you can be continuing to pay for a lifetime with the damage that can be caused.Don't forget that these chemical mixes become less and less successful with time as the plants you are trying to kill become resistant to them.  In the meantime we are all subjected to repeatedly breathing them in and ingesting them.There are some areas where there are really problematic plants which do need the very specialist and careful treatment by specialists with experience - but not everything everywhere does. Its horses for courses.

The Science DOES NOT say that Glyphosate is safe to use. This has NOTHING to do with ANTI-VAXXERS or Trump or RFK.  In fact I believe that Trump actually wants to pass a Beautiful Bill to stop any restrictions on anything whether questionable or proven to be problematical - as glyphosate has been - which is why there are strict instructions and restrictions on how to use it - despite its huge availability which is likely to encourage its use or misuse rather than discourage it - because it is big business.There are huge corporations making a lot of money out of these chemicals and a lot of gullible people who think that because something makes life easier for them and has been 'passed' by an authority it is most definitely safe and therefore a cheap solution.  It is far easier to think about saving money and effort than to think any further and wonder why there are so many court cases being brought against the manufacturers and why people should be erring on the safe side and shouldn't be spreading it around and using it when there are - as there are - alternatives. Hindsight is a fine thing.When you have big companies doing their own research and marking their own papers and not providing all the information requested for a regulating authority as has been  alleged there is very good reason to be worried.  There is a tremendous amount of lobbying of those people who stand on these Committees.  It has only just been approved by committee and only for short extensions of time. The effects of tobacco and asbestos weren't and aren't automatically immediately noticeable.  With tobacco the dangers were deliberatly hidden for many years despite the knowledge of the danger being known. We now know there are problems with asbestos but we have masses of public buildings in the UK riddled with it and the advice is just that it is safer to leave it undisturbed than to disturb it.  Well that is cheaper than building a lot more new public buildings - but how often are workmen and teachers and other users of these buildings warned not to make holes in the fabric of the buildings or to take action when panels are kicked out and broken? There are very strict rules of how asbestos should be taken out and disposed of but we know that that often doesn't happen.  Diagnoses of mesothelioma aren't made immediately after exposure!Regular brushing of paving with a stiff brush will stop most seeds taking root.  Nowadays Thames Water seems  usually to be left to deal with all the dead flowers from flowering trees and dead leaves that are left on our streets until they are swept down the drains by rain.  These gutter gardens are what just about all the plants on the streets grow in!  The gutters never get swept because our streets have become permanent car parks and the Councils and Contractors seem to be unable to organise any regular cleaning. If residents sweep the streets where is the detritus supposed to be put?  I remember a newspaper article telling of a time residents were fined for sweeping leaves off the pavements into the road.  Now that garden waste is no longer allowed in the ordinary bin and soil is not allowed to be thrown anywhere - where do pavement sweepings go?

Having read the hysteria presented locally, that is like so much currently, myopically short of actual fact and not entirely true.  Just possible in modelled scenarios.You could apply these risks to almost anything chemical in the average household. Even Vinegar.If you use it properly and responsibly, there is no risk.  There are places which use Glyphosate in a rather eyebrow raising ways. In the U.S. it is sprayed by vehicular machines in suburb and some places, using high pressure.I don't think that has ever been deployed here and most certainly not in urban populated areas.It has been used for a very long time with no actual reports of any direct impact.  However in this country Locally it is sprayed directly at low pressure to the plant or at risk areas like paving joints and wall lines. And closely.In a lot of districts the area if badly inflicted by weeds, the pathways are closed off for a short while whilst treated and reopened when the treated area has dried off which is usually quite quickly.Many think that that is a simple but prudent means to minimise any potential risk further.Stuff used prior going back to the post war years was far more nasty and killed everything. Glysophate simply kills to the root.It has to be remembered that many species of weed have incredibly ling tensile roots and can do a huge amount of damage. One pretty looking plant can have a root system capable of dislodging a 30kg paving slab.  Walls can be destabilised, ducting cables and sub surface infrastructure, seres and drains can all be seriously damaged in just a few seasons of growth, faster than trees.Wild plants and weeds also carry seeds, often have skin and respiratory irritants and toxins that can harm us and domestic animals.  Remember that most of our modern medicines and poisons are largely from plants and again if not used with care can be equally harmful.The cost of damage, increased insurance premiums and the unkempt look of residential streets and recreational areas - which are meant to be safe for all and devoid of harmful vegetation is a bigger risk against using targeted chemical preparations which can and are used in the most responsible of methods.The key is applying properly and in the safest possible way.  And the responsibility is really with those who oversee such operations , adhere to that.  Which in this country has been very much the norm for the past 40 years since safe handling regulations came about.
