A superweed spreading throughout the UK could be brought under control by introducing plant-eating predators from Japan, scientists believe.

Japanese knotweed was first introduced as an ornamental plant, but has since plagued the environment; removal is costly and time consuming.

Now a team has identified natural predators from its native home that could also control it in the UK.

The plans have been submitted to the government for approval.

If the proposal gets the go-ahead, it will be the first time that biocontrol - the use of a natural enemy to control another pest - will be used in Europe to fight a weed.

i'd be a bit wary - biocontrols have a habit of backfiring...

I'm very wary about this. I know Japanese Knotweed is a terrible pest - which should never have been introduced - and is very difficult to eradicate, but what will the exterminator turn to when (and if) it does away with the knotweed?

If they bring the aphids and the fungus to Ireland, I swear I will be the first in the que, these plants are the worst problem in Connemara after the purple rhodadendrum
