Hi All,

I sowed a new lawn back in mid-autumn. Now I can see a lot of weeds
appearing, along with the grass.

I remember seeing a weedkiller in the form of a glue-stick-like product
that you touch onto individual weeds, to kill them, has anyone found such a
product that works? I would like to avoid having to go back over the whole
patch a 2nd time, re-applying, to achieve proper eradication.

Many thanks,

Al

You're probably thinking of this:

Years ago, I think you could get a similar device containing paraquat.
I'm not sure that paraquat is still available, let alone in stick
form, because it's highly toxic and quite a few people died from
accidental or deliberate ingestion.

But now is not the time to apply it, as it won't be very effective at
this time of year. Nor would I be too worried about weeds in a new
lawn at the moment. Most of them will be annual weeds, that a bit of
mowing next spring will soon see off. The ones that remain can be dug
out individually, or sprayed with a selective hormone weedkiller for
lawns, such as Verdone. But do it in the spring when the grass itself
is a bit more robust.

Paraquat was chiefly sold as Gramoxone and was chiefly used by
professionals,but was banned by the EU a few years ago.
Diquat is sold as wedol and a few other products but will do your
grass no good. it's a contact killer
I'd do nothing till the spring and then only after you have mown the
grass 2 or 3 times, then decide if you can spot treat or spray the whole
lawn as Jake says.
