These blighters won’t die.

I have been felling with a chainsaw to about waist height (MrD’s advice) and then immediately slopping on a goodly amount of RoundUp.

Sadly these things (grrrr grrrr) are shooting from further down the base.

I was considering Grazco, but it’s so deadly one needs special gloves, the goggles and a respirator…plus clothing at least like mechanic’s overalls…

Am really running out of time, these things are flowering and fast getting past the effective poisoning stage…

Anybody out there up to speed with these poisons?

I was under the impression that Grazco was a pre-emergent? Is this true dinetta0?

you could try a Blackberry and Tree herbicide. Hortico and Chemspray produce one. The active ingredient triclopyr is claimed to be non-persistent in the soil.

Or you could try respraying the new growth with a strong concentrate of Roundup. Don’t know anything about the other one.

PM, What does pre-emergent mean?

BlueGreen, I use the Roundup neat…straight on with a brush…within 60 seconds…

I buy straight glyphosate for a weed killer. Not roundup or zero. Do you use glypho?

Noooo

OK perpindicular learning curve coming up by the looks of things…

I thought RoundUp was a “glypho”?

It’s not?

What is a brand name for a straight glypho, please?

I’ll go down and check the name. We get it a the B…place. The last container was a different brand to this one.

Thanks Pomolo…no hurry…before the weekend would be handy tho’

The active constituent in Round-Up, Zero and others is Glyphosate.

Pre-emergent is a herbicide that you apply to the ground, and it stops any ahem weeds from germinating, or emerging from the soil.

glyphosate is the active ingredient found in Roundup and Zero. Roundup has other (nasty) chemicals added to it, and Zero is a diluted, ready to spray form. You can by “generic” brand glyphosate at the B shop or nursery and is more likely to be just the straight concentrate and cheaper.

What I plan to do where the seedlings are (too many to pull out) is avail myself of the free council mulch and smother the bugg*rs…

Not sure if RoundUp is used as pre-emergent…not sure if I like the idea but it’s probably what they do prior to seeding the crops on the irrigation farms …

I think there’s defoliant in the air this morning…the place looks like an end-of-the-world survivor’s camp at night, all the harversters madly making the most of the dry…

So it’s like ‘once a year path weeder’ ?
Nasty stuff.

Got it. It’s a Gulf Ag product sold as CLEARUP BIO 360 HERBICIDE. Active constituent 360g/l Glyphosate.

I’m sure any garden shop would have some kind of straight glypho product.

I just go to the B shop, look at the labels on them all, and get the one with the highest concentration of glypho..

Sorry dinetta0, I did not mean to infer that Round-up or Glyphosate was the pre-emergent, which it certainly is not.

I was asking if the pre-emergent was the Grazco? I know of a product called Grazon which I know of people who will mix Grazon and Glyphosate together so that they kill the current weeds and hopefully the next lot of seeds that germinate, and this is more likely what your local farmers are doing at the moment.

Now, what do you use Grazco for?

No need to apologise PM, no offence taken …not sure why you thought I was but there you go…

Grazon! That’s the one! My apologies to all who’ve mulled this over, I had the name wrong :S

Oky Doky then… from what I know and I could be wrong… but in the battle for weed supremacy, the Roundup will kill the emerged (or post-emerge) weed whereas the Grazon will hang around for a while and kill the soon to emerge (or pre-emerge) weed.

Now I have never used Grazon so I ain’t 100% sure if this is the case, but I was talking to a bloke once who mixed the two together in order to keep the edges of his path clear. So I guessed that he used teh Grazon as a pre-emergent.

However, it maybe a woody weed killer… I need to see the label, dinetta0, you need to take a photo and post it here, or I could always google.

http://www.nrrbs.com.au/grazon.htm

Does this provide you with the information you need, PM?

Get some goats. They’ll eat the lot. Maybe borrow some.

Grazon is not used as a cut/stump treatment but as a spray on actively growing weeds. Methinks!

Research suggests there is a society for control of leucana and further investigation suggests using access herbicide mixed with diesel and used as a cut stump control method.

See here for details of the chemical

and here for the leucana control mob.

Seems a decent local produce store should be able to advise.

Dinetta, How about cutting it down right near the base and putting more round up on it, Just round up Not watered down should do the trick i reckon.

most things will die if you cut them off at the base – drill a few 10mm diam. holes and pour neat glyposphate into the drilled holes.

i never had to deal with leucaena tho’. hard work by the sounds – a bit like our feral olives here.

That link helped heaps dinetta0, thanks. Now forget everything I said about pre-emergent herbicide. Grazon like Roundup is post-emergent.

Looking through that site, there’s some inneresting information and as Longy says, try the Access mixed with Diesel 1:60 and apply to the Basal Bark and/or stump cuts.

It doesn’t look like Glyphosate or Grazon will touch Leucaena….

We want a stump you can see so we don’t trip over the b****y things…

Not leucaena Mate…I’ve cut it off at the base, under the soil, topped with a tin and soil on top….hahahahaha …back it comes…

It’s great where it’s meant to be, in a fattening paddock, and works if they keep it under control..but keeping it under control for the graziers is part and parcel of their expenditure in producing fat cattle…it’s a timewaster for me…

the small shoots that come up, I’d be foliar spraying with the Roundup or Grazon, but the stumps, I’d be going the Access and Diesel. Having said that, I reckon it’d be 3 years in the killing.

Good tip, thanks PM, re the foliar spraying of the regrowth…

Still reading my way through the websites Longy put up, have printed off the Access info and will shortly print off the eradication society info…did you see on the eradication website where the trees have roots that can go down for 6 metres!!! Makes me feel I’m on a hiding to nothing…perserverance is the key I think…

Thanks for all the tips in this post; Longy…I’m tempted with the goats I can tell you…have printed off the info on the websites, hadn’t come across them before…

So between you and PM, Grazon is out, glad I didn’t waste my money on it…MrD is away until Sunday so I’ll get him to look at the downloaded info…

my sister got goats to control her blackberry problem and hasn’t looked back…

Drill holes in stump, fill holes with diesel daily, and its dead dead dead.

Just diesel? True? am still keen on the goats, tho…

How about cut it to 1 metre level.

Cover it to ground level with a thick black garbage bag. Squeeze out most of the air (so it is less likely to blow away), then anchor with blue metal around the bottom.

Then repeat with a second bag.

Keep an eye out for shoots. Treat them with petrol on a paintbrush, liberally.

I might be hopeless at growing stuff, but killing things? No sweat.

LOL! thanks for the interest Collie!

Well I took Collie’s advice on board, and the “paint ‘em when they shoot” has paid off…there is such a lot to do but it doesn’t seem to matter what stage the leucaena is at, the RoundUp knocks ‘em silly…
