Well, if the labels on my poisons had any useful info about the plants they kill, I wouldn't be searching the 'net for that info! "Most broadleaf weeds" is all very well, but I want more info than that.

Agreed Roddy, it was only after reading the Hotshot information on the web and then downloading the Hotshot Lantana Control as well as speaking to a Dowagro rep did I actually decide to use this particular herbicide for control of Lantana on our property. I see the rates have changed slightly from my control guide which is about a year old. Hotshot has certainly proved more effective than Grazon, 2,4-D or Roundup as well.

well, after all that, I eyed the forest of 6+ foot tall weeds (mother calls them Pemican or something similar), got the long-arm tree loppers, and hoed in. Took a few days, but chopped them all down to dirt level. If/when they try to sprout new stuff, I'll hit it with the chemicals. They're woody, it seems.

... and while chopping, had to be bldy careful, as the chihuahuas were stalking around in them, and the loppers would've found them easier going than the weeds.
The dogs like to help with jobs like this. I'm not sure what they're doing in there, but they feel it's important.

I know the feeling ant, my faithful mutt loves to help out my photography by flopping herself down in a nice central rock pool as I'm trying to capture some running water!

I know your pain when it comes to chopping weeds, doing the same kind of thing myself at the moment with wattle regrowth, if you paint the stump immediately after the cut with some roundup you should sidestep the whole regrowth problem and you don't have to worry about overspray hitting other areas you may want to preserve.

Good idea, I might make up a tinful of roundup to attack the last ones.

I just spent a few days treating isolated prickly acacia with Velpar L. Finished on Sunday, and got 46mm rain yesterday to activate it so should get a good kill.
I love the stuff. Its clean to apply, no spray drift, and you can usually treat the bush without pulling up on the bike. A 5 litre backpack lasts many hours in our situation, so no need to carry around extra chemical for refills.
It can't be used in watercourses, so I'll have to go back after the Wet, and treat those trees with Starane and diesel.

Just re-visited this thread to find which poison it was that damages trees. We've planted extensively on this place, hundreds of eucalypts and exotics too, with irrigation. I might return the Kamba to the family farm, as pretty-well every bit of this place potentially has tree roots. Might explain a few failures over the years, or trees that just sit on their bums doing nothing.

I seem to have heaps of thistle rosettes looking very healthy. Anyone know is this season a good time to hit them? I have some standard fleshy green ones, but also a lot of grey ones growing very flat to teh ground. I was hitting them with the adze yesterday, but some areas are so thickly carpeted with them, there's just too many, I need to spray.
Glyphosate?

Simply put, successful use of herbicides requires some basic knowledge of plant culture. Whether the plant is an annual, perennial, or bi-ennial is very important. For example, Patterson's Curse is a bi-ennial which means its lifetime consists of 2 years, an annual 1 year ,and a perennial lives on for possibly many years. But also, most perennials are classified as warm season or cool season perennials. There's no point spraying for Paspalum in July as the plant is dormant. Spraying while the plant is in flower is also a waste of time as the plant is diverting all it's energy from it's roots to the inflorescence to develop viable seed. This is why you will sometimes see a dead weed with pretty flowers on it. Another tip is to wait till a warm day, not a cold or hot day, as the leaves on the plant have small openings called stomata. These small openings are not to dis-similar to the pores on our skin and are used for resporation and evapo-transporation(moisture loss) except that the plant can open and close them when under stress to preserve moisture from heat and frost. Some weeds have very hard to wet leaves and use of a surfactant is recommended to help it stick, along with Canola oil as this breaks down the cell membranes on the leaf and aids the intake of the herbicide. As put forward earlier, a colorant is very helpful and I like to use blue as this makes the turf look a fantastic deep green for a week or so.
As I am a turf manager, if anyone would require some more info(turf species, fertilizers, diseases), please do not hesitate to ask... :wave:

Ive been doing a fair bit of clearing in the back yard I have these tree stumps that I keep poisoning with round up but they keep growing back does any one know what would kill them off for good?

Good points, Simmosturf. We often do forget to look at the whole picture of these weedy plants. I guess, put simply, if they're growing leaves, it's a good time to hit 'em!

As for tree re-growth, I guess they're "woody" rather than "broadleaf" so use a poison for woody stuff.

There's a product called "Access" that council's use, but it isn't easy to get hold of due to it's poison schedule... you may need a farm chemical user's ticket to get hold of it.

Thanks for the feedback Ant and simmo I will certainly look into it.

Can anyone ID this weed that seems to be growing everywhere around here... It grows as a mat on the ground choking out all the grass...It sends a root down at every nodule.. Clik the links but the pics are largish in size(500kb)to get a good look at the weed..

I see Access was mentioned as a herbicide...Just remember Access can only be mixed with diesel..

Dunno what that is RC! Reminds me of the stuff they plant on sand dunes to stabilise them.

I was planning to have a go at my thistle rosettes tomorrow, but they reckon "possible rain". Now, there's no way it's going to rain as it doesn't do that here any more, but if I spray, it WILL rain! Maybe I'll spray.

They forecast rain maybe today, so I figured what the hell. Such a forecast meant no frost, and with our record, no rain either.

So I mixed up a backpack (Hudson's sprayer!) of roundup with wetting agent and some pink stuff.

That pink stuff is brilliant, I did 7-odd acres of spot spraying (some carpet spray) of illyria thistle with 17 litres, with the pink stuff you can see exactly how much you sprayed, and what you sprayed.

I used to do runs of Knock-Down in the family orchard, and you just didn't know what you'd got unless you did another run in the arvo and saw what wasn't wilting. Kind of annoying to get the tractor out again.

RC - I had this weed growing in my yard as well - not sure what it is called either but hit it hard with weed killer 3 days in a row and it has now died. The roots are very deep and if not hit with enough weed killer seems to come back even stronger. I sprayed it 2 weeks ago for 3 days running and then dug out all of the roots and it hasn't come back yet!!

Just spent a day in the classroom to try to obtain a chemical accreditation..Not that we currently need one in Queensland as Endosulfan is the only restricted agricultural chemical up here but no doubt in the future they will start adding chemicals to the list as they have done so in NSW and Victoria...My brain is still throbbing from all the info I had to take in and then digest and spit out on the exam paper...It's been too many years since I last went to school...

This thread is useful in many ways, and I can see when it was that I did my thistle spot spray.

I went around and had a look last weekend, and the kill-rate on those thistles was fantastic. Big fat rosettes just dead! However, I must have missed some or perhaps they were too small to see, but there's more to get. And on my walk round I discovered Patto's grows well in winter. Apparently you use Glyphosate on that, too, so another spray run is warranted.

I'm told that, if the spray dries on the plant, then rain a day or so later is OK? Anyone have an opinion on that? they're forecast "possible showers" on Monday.

Interestingly, the time to hit St John's is when it's first flowering. Wouldn't have thought that. There's a special chemical which targets St Johns and not the plants and grasses around it, called Fluroxypry. I have quite thick infestations so come spring I'll get some of that and start hitting it as it flowers.

For Patto we spray with Igram/Thistlekillem mix. 3lt Igram 5lt Thistlekillem in 1000lt water enough for 7 hectares. Can't spray over 18 deg temp or when frosty.Good time now while plants small.We still get odd plants it did great job for us.
