which weed/plant chemical, tradesmen use to clear a garden

[ghost32]

I'm starting my garden this year, and it's a mess. I had a company come in a quote 7k, which they then broke down what needed to be done.
I'm now intersted in trying to do some of it myself and as such need some pointers.
They said the first thing they would need to do is chemically spray the area, as there are some very hardy weeds that will come back if they just rotovate and level it.

they said they might need to go over the legal limits with the dosage, to make sure they get rid of them all.

any ideas what chemical they are on about? and will it get rid of everything? including hard barky plants? (ivy etc)

There are lots of different types of weedkiller that the 'pros' use. Gallup is a popular one, its glyphosate that you mix with water....lots of water!...they use Gallup when clearing forest paths!

There is also Kurtail which is very strong, thats an ammonium based weedkiller, you would only need about 20ml in a litre of water to have a strong solution.

I would be a little wary when a contractor says he will use more than the legal limit though.

That is exactly the kind of rubbish contractors say to try and impress you and somehow suggest you will be getting special treatment! It is nonsense. Most weedkillers will not be more effective by simply concentrating the dose, increased effectivness can be achieved by using surfacents and adjuvants as additives.

There is no 'legal limit' regarding concentrations unless you are using it near water courses. There is a legal limit however on applying certain types of weedkillers professionally and anyone doing any spraying should have the relevant PA licenses.

Please post some pictures, as that seems a lot of money, unless you have a forest in the rear garden.
