Thread: Weed control

A mate is an agronomist, he can rattle off the toxicology effects of even the most benign herbicides like glypho and it's pretty sobering.

The old things like esters were bloody scary, one of the old weed officers, an ex-cockie warned me off using any esters at all, thay are just too damaging and what is being observed now is the DNA damage that isn't showing up till the generation after next, so it's not your kids but grandkids that have the birth defects.

I'm glad I'm not on the farm anymore mixing up hundreds of litres of the stuff, it's bad enough I go and spray out 15l at a time of di-camba/MCPA.

Check out Tordon (monsanto) also known as Agent White, does the job of Agent Orange, except it is injected instead of sprayed from C130's, Regards Frank.

Tordon is from Dow (or at least used to be)

It uses Picloram as used in the Grazon mentioned above with 2,4-D

[edit] Selective herbicides are great, if you use the right (licensed) herbicide for the particular plant you are trying to get rid of and you use it at the correct dosage.
The old cliché was "a slow kill is a good kill"

The other really important factors are that the plant you are trying to take out isn't stressed in any way, and that goes for water stress as well as drought stress, otherwise the uptake is really compromised. The plant has to be healthy and growing well for the best results.

It's a bit of an art and a lot of science getting a good kill on weeds.

Rick, the trouble with Tordon (and other tree killers) that it has a chlorine base and when it is burnt, as in firewood it produces Dioxins and Furans and they are POP's, Persistent Organic Pollutants which build up in animals/humans and can't be got rid of. Have the spec sheets and labels here somewhere from Monsanto, Regards Frank.

Hi Matt,

About a year ago I bought 10 acres of prime land on the Bellarine and wanted to get rid of a bank of kikuyu (over 100m x 5) and some other stuff (about another 1000 sq m).

Soon to be ex GF had a 100 litre tank / sprayer combo with a pressure (demand ?) pump, 10m of tube and an adjustable wand. They cost about $600. Had a dinky boom as well which I didn't use.

Bought 20l of generic glyphosate ($100), ex landscaper mate advised 10% and away I went spraying out the window of the ute with the tank on the back, pump hooked up to the battery.

Result: obliterated everything including a couple of gums and a couple of wattles that were not targeted. I was careful to avoid their leaves but not careful enough.

Only took an hour.

cheers, DL

Napalm....

In order to make napalm, first you must make soap....

That's a real good way of getting what ever your spraying noticed by everyone, I have seen damage done from farmers spraying on a warm day with little to no wind but have the wrong nozzles on where it gets into the air stream and drops on an organic hippy farm somewhere miles away.

Right then is when all hell breaks loose and yes it is very easy for them to track down who it was and even easier for them to test a sample and match it to what you have sprayed.

Not entirely true, you just need to know what your looking for and where to get it e.g. Rygel Australia - extensive range of agricultural adjuvants/ surfactants and turf management products including Gullf Ag try a look at Paraquat 250, nice non selective herby with nice esters and salts that will take the lead out of your pencil for good if you get it anywhere near an opening in your body.
Garlon is another good one that is very good when blended with Glysophate and a wetting agent and it has a reasonable residual.

There is a granule that you can put out from a spreader but the name escapes me right now. It doesn't sterilise as such the dirt but it damages the cells in the seed so it wont germinate and being a granule, it stays around for a long, long, long time.

Golf courses use it to get rid of Kikuyu out of finer turf areas and after it's dead you need to sod down about 3 inches to remove it before laying new turf.

If I think of the name when I'm not so tired I will text it to you Matt.

The gum tree's and wattle tree's wont be effected by normal Glysophate, it can't react with woody plants.

What ever you used had something else in it.

If using some thing like Paraquat, ALL the safety advice must be followed as it can really kill you really easily and not very nicely either.

My oldman who was an Ambo through till the late 90's tells a story of a bloke they had to transport to hospital in the back of a ute as he had accidently ingested some and was leaching toxic gas which had already also taken out his son and wife who were rushed to Melbourne by Ambo.

All they could do for the bloke was charcoal him and pump him and keep the O2 up until he passed as it just ate him from the inside out.

It's not the reason that the greenies don't like these chemicals that has banned so many, it's more that the people using them never used them properly.

I've been involved for many years with spray equipment in the turf industry and can say that things are getting a lot better than they were but still if using any chemicals including just your run of the mill roundup, please be careful and please follow instructions.

I could go on forever with horror stories but that would get rather boring.

Needless to say, I have copped a hospital stay from a dose of an un-known chemical in a spray unit that I was repairing and it's not nice and I still have health concerns from it till now.

Hey have a look at this as well, there are several types of Roundup or you could add Sempra as well for a bit of extra kill http://www.nufarm.com/Assets/15291/1...nity_Aug10.pdf
