Default Pre emergent herbicide in the UK?

In article ,

Hi all,

My new garden has a terrible crabgrass infestation - I have around 20%
grass and 80% crabgrass both on my front and back lawn!

I tried a 'moss killer' lawn product in the autumn that turned some
patches brown but they soon bounced back. I read that a pre emergent
herbicide was the best thing to use so I have bided my time until the
spring approaches.

However, now when I come to try and buy a pre emergent herbicide I
can't find them anywhere. I am in the UK. I can see lots of American
products (surflan, Pendulum etc) that do the job but they are not sold
here. Can anyone suggest a suitable product that is available in the
UK?

Thanks, Dugald


Do you know what surflan or Pendulum are? Do you know the consequences
of using them?

Pre-emergent herbicide

http://www.gardenword.com/preemergent.htm

A pre-emergent is a chemical that prevents seed from germinating or
prevents seedlings from growing to maturity.

There are many different pre-emergent herbicides. Most are used on lawns
to prevent weeds.

Synthetic chemical ingredients include benefin, isoxaben, pendimethalin,
atrazine, dithiopyr, trifluralin and others.

The only organic pre-emergent available at this time is corn gluten meal.

Pendimethalin - American Cyanamid Co.
Pendimethalin is a preemergent herbicide used to prevent crabgrass from
germinating. It inhibits cell division and cell elongation. It must be
"watered in" so that the chemical reaches the seeds deep in the soil.

Pendimethalin was included in a biocide ban proposed by the Swedish
Chemicals Agency [2] and approved by the European Parliament in January
13, 2009.[3]

You may not care, but if I was your neighbor, I'd be in your face.
