Commercial quality weedkiller for lawns

[CIS121]

I'm after a weedkiller for lawns that wont damage the grass. Any landscapers out there that maintain lawns/grounds for a living?

Plenty around, but why commercial? What's wrong with the domestic ones (apart from the risible prices - £1000000 for 1.2ml!)

If you go to a farm services place they should be able to sell you some 'Grazon'. This kills dicotyledons, leaving the monocots (ie the grass).

They might but they shouldn't:

And clopyralid no longer in domestic market apparently: http://www.grounds-mag.com/mag/grounds_maintenance...

Thanks folks. The reason I asked for commercial is after trying some poor B&Q products before. There are so many lawns maintained by professionals that are weed free over a wide area that I was keen to find out what they use. Grazon looks like the stuff!

Thanks again

I've used Grazon on our paddock and it's fantastic at getting out troublesome patches of nettles and weeds, however for a domestic lawn I'm not so sure.

Perhaps in low concentration it might work, but in the standard concentration from a knapsack sprayer it turned the grass around the weeds I sprayed brown (didn't kill it, the roots survived and re-grew) which probably isn't what you want on a domestic lawn. Bit of an overkill for domestic use I'd say, it's benefit is that livestock can get back on it (and graze on, geddit?) after a couple of weeks - the reason we used it in the first place.

You can buy it if you've done the relevant COSHH course or you were born before (IIRC) 1963 as there is a grandfather law allowing older farmers etc. special dispensation so they don't have to go on the expensive 'stating the bleeding obvious' course.

That must be why I've never had a problem buying it, I'm an old fart.

I can recommend Verdone, use it on my lawns and it does what it says on the tin.

Check out Pitchcare.com or Sherriff Amenity.co.uk for an array of selective herbicides as used by Greenkeepers/Groundsmen, ( certificated users! ). Scotts Re-act is a good all-rounder. Alternitively get a lawncare company in to do it for you, ( Greenthumb, Greensleeves, Lawnmaster etc..)
