It was Tesco's own brand

If it was the *Tesco path weed killer this is known as and manufactured
by DOFF (http://www.doff.co.uk/) Long lasting path clear.

It will stay resident and active in the soil for 3 - 6 (maybe even
longer) months. Best to strip off the top 4 to 6" of top soil and
replace or wait a good 12 months before you plant/seed/re-turf.

You cannot 'water' this out as you will just get a diluted solution
causing 'run off*'.

PRODUCT DESCRIPTION

Tesco Path Weed killer.

MAFF CODE: M12754
Actives: 2,4-D "AMITROLE DIURON" (AD)
More info hehttp://tiny.cc/DJfd3http://tiny.cc/2t1UWhttp://tiny.cc/6YUSL
Intended manufactured field of use: HOME GARDEN WEEDKILLER ONLY.
Manufactured and approval holders: Doff Portland Ltd
Authorised (UK) outlets/retailer(s) (amongst others): DOFF Portland,
Asda, Tesco, Wilkinson, B&Q and Focus Stores Limited.

If you have had the heavy rains the Amitrole Diuron may/will have been
washed past the 6" top soil mark and possibly much deeper

You may even have a diluted '*run off' to other areas of your garden.
This will stunt or slowly kill plants coming into contact with it.

This is why you should always read the label/instructions with any form
of chemicals/feeds/bug control/cleaners etc., you are going to apply to
your home or garden - the affects, as seen, can be very destructive and
hugely expensive to rectify.

Since it was last year that whatever herbicide was applied and he's
tilled, added material, etc, it's also possible that it has nothing to
do with the herbicide. Was the area that was repaired kept
watered? If not, it could just be that with high temps and no water,
it had insufficient roots to survive.

First thing I'd do is go find another bottle of the herbicide and read
the label. Even the long lasting ones last about 6 months at best.
And I would suspect they would be more likely to cause the new seed to
fail immeadiately rather than look fine for a few weeks, then die.
