Himalayan balsam

[mixed breed]

In trouble with landlord, Is there a pesticide that kills it?it's just starting to flower.. tia

Hormones make it very poorly, but must be a bit big now...

What is the situation is it growing in? I used a knapsack and ( I think 2,4D) a couple of years ago which seriously depleted it.

 

[davidroberts30]

I dont think I'd be tempted to spot spray it with forefront

 

[RAF]

Roundup a lot last year that cured it

 

[suffolksmallholder]

Wrong plant. I eradicated Japanese knotweed not the above
SS

It's about waist hight atm, its been rife in the neighbours wood and the brook banks since i was a kid, but I put some new barb fences last year (two foot from hedge/boundary line) and it's now growing there like fun, I guess the cattle trampled it before and kept it at bay..

It's an annual so you could wipe it's all out now and it will still be back with avengance next year.

 

[Red Fred]

The local wildlife trust have obtained funding to pull it along our stream banks and they have pretty well eradicated it in 2 or 3 years. It def. doesn't like cows.

seeds are viable for two years
you can get rid by pulling it, we did

 

[Bury the Trash]

Yes forefront (aminopyralid) does a thorough good job on it , even just flowering.


But How about something with triclopyr in it like grazon pro....


Even looks a lot better if you cut it actually .

Ours is all on the river bank and there's acres of the stuff upriver from us, it makes it feel like doing anything to our bit is a waste of time until there's a unified control strategy in place.

Did a small patch a couple of years ago in a garden, you need to cut it near ground level and then spray the fresh cut straightaway with round up before it seals itself. Dont leave any parts laying around or they will produce new shoots next year.

 

[Montexy]

Apologies, I was talking Knotweed - reading through looks like someone else made the same mistake!

 

[mixed breed]

Perhaps I'll stick to my first thought, strimmer with a blade and get it cut before the seed heads explode and then spray any regrowth. Just thought, am i breaking any "rules" using roundup on the two metre margins? This guy's watching me like a hawk

 

[melted welly]

Cut it, and roundup.

Callisto will do bit of a job pre em too.

can pull it easily too, shallow rooted.

If all your ducks are in a row, licence, training and appropriate nozzles on sprayer then you can face him down, if not he's got you over a barrel and you're back to strimming and hand picking.

 

[Devil's advocate]

Is it Bay willow herb?

So many confuse the two, the willow herb easy to kill, but not with roundup.

I don't think there's any LERAP on roundup?

 

[dudders]

Pulling it worked well for me - get hardly any each year now. But, as has been said earlier, don't leave any lying on the ground. Amazing how it puts roots down. SBK also does for it, but I still prefer to pull.

No need to use glyphosate for Himalayan Balsam. I looked into it when I reclaimed a track here, that had had s9me builders rubble levelled in it by a previous tenant...

Pastor/Thistlex kills it effectively, as does strumming it off (or grazing tight) regularly to stop it flowering/seeding. It’s not notifiable, so not sure that your landlord can insist you do much about it legally, but probably best to placate if you want to keep renting there?
it’s pretty easy to control ime, but will take a couple of years for seeds/shoots to give up.
