Disposing of Horsetail and Brambles

But that issue - to be fair - is with one person. You know, Im sure, that passing on pernicious weeds even if they are used on council land is unfair, and are very likely to spread to private gardens. Thats what they pernicious weeds do 
Its not a preach I promise you, but I think its wrong, and unfair on people who have no argument/dispute with you.

Its not a neighbourly attitude however you want to see it. 

We differ. You see this as an issue of passing on pernicious weeds. I do not - I see it as a matter of responsibilities in this sense:
If I as an individual (ditto a local council as an individual body) elect to take on some activity then I accept the responsibility for my actions. I do not welcome some busybody coming along to question whether I am doing it right unless they have firm reason to suppose that I am not.
So, the council has adopted the responsibility for collecting and processing certain refuse and have issued instructions to the public as to what they will accept. My responsibility in this situation is to make sure that I adhere to their instructions.

As I said, it is a very welcome service. What else should I do with wood clippings and roots? I can't burn them and I would not do as some do, i.e. take them to a quiet road and dump them.

I am very much living up to my social responsibilites and I resent the accusation that it is 'not a neighbourly attitude' since in fact the reverse is true.

Would you use/buy compost from your council on your garden or your plot?

Certainly would if they were offering it free. I don't buy compost/manure from anyone. But if I found a problem I would, of course, report it to them and follow up before buying any more.

However, there is a question unanswered - what should a person do with diseased or other undesirable garden waste if it cannot be burned?

ive only had an allotment 3 months and i'm the same got tons of meres tail.i was talking to one of the other plot holders who's 80 bless him and he said if you put turnip seeds around the meres tail its supposed to keep it away.

That doesn't sound a very high concentration. It's usually 30ml per litre for stubborn weeds.

Anyway, you should always dilute according to the label, not what you read here.

Yes I am pre-supposing.

That was the experience with our council who suggested taking our skip away to compost it, until it was pointed out that the stuff that went in there was the stuff we didn't want to put in our compost.

Nice mix of mare's tail, docks, blight, club root, white rot................

They admitted they hadn't thought about that.
