Best weedkiller product for perennial weeds?

TUVOK

My son has a problem with perennial weeds growing outside and inside his garden fence.
The land outside is owned by his local council but despite asking for it to be controlled, it's never done.
Perennial weeds are growing in from outside and being partly disabled he cannot cope with physically attacking the problem.
Thus he needs a weedkiller product that will do the job of stopping the weeds at least for a few months.
Suggestions, recommendations for a suitable product please would be appreciated.

Thank you.

He needs something systemic, goes in & kills the roots

Usually systemic ones contain Glyphosate

A well known and available one is Roundup, but own brand will do if it contains glyphosate

The chemical is inactive on contact with soil, but will be in the plant

He will not see instant death, it is gradual as plant withers & dies over time, best applied in growing season, now is ideal

You will find lots of horror tales about glyphosates, DYOR but used as per instructions it is fine

Many councils have introduced no spay policies in an attempt to improve biodiversity so on no account should he spray areas that he does not own.

No, checked, they have no biodiversity policies, their only policy is allow it to become a jungle for weeds, for dogs to use as a 'fouling' area and for rats to be shielded from anyone.

Most weedkillers are based on glyphosate and it does the job on most weeds. I use Poundland's spray but if this is a big area it may be easier to get a dilutable product and a dedicated cheap watering can

That still does not give anyone the right to use toxic chemicals on the councils land.

Weeds are part of necessary biodiversity, policy or not. There's an adage that "weeds are just flowers in the wrong place" - they provide important environments. The dogs and the rats are largely a "human problem" not a weed problem. And I presume that you are not going to be complaining about the council tax bills any time soon if you think that councils can afford to "fix" weed problems when they can't afford to provide support to vulnerable children and adults?

Must admit I find councils a bit random in what they think is appropriate to maintaining public land.  I quite get the biodiversity and save the bees bit but I've also seen them spraying along the pavement where there are both weeds  on the ground and lovely plants growing down peoples garden walls.  The problem being that the people doing the spraying don't know a weed from a flock of sheep.  And so there are chemicals being sprayed on things that shouldn't be sprayed and that home owners don't want to be sprayed.  And they'll also let things get so overgrown that road signs and clear views for drivers are blocked.  

The only place I've seen it work nicely is in a few areas where there are neighbourhood groups that have taken over the verges and plant out lovely arrays of flowering plants.  Presumable they have the council's permission.

No reccomendations re weedkiller, but you could jon your local gardening group and ask if anyone could clear the bit by his fence...they can only say no...

Perhaps similar to your son, I have a chronic condition which means I need to pick and choose what I do in the garden - one solution for me was to find a local gardener who can come out once a month to manage the grass and weeds in the part of the garden I can't physically cope with. 

An extra plus for me is that if there's any other small 'handy' or maintenance type jobs I need doing then I can just roll them up and get them done once a month. 

But otherwise I agree glyphosate based is the way to go - if he just treats the weeds on his side of the fence I doubt anyone can reasonably complain (glyphosate kills the roots so if the weeds are truly invading his garden from council land it will sort the problem while not killing anything that's not)

We've found dishwasher salt works well. Cheap to buy in supermarkets.
