Wetting agent is more than just a detergent, but not much more... Dishwashing liguid is fine as all you want to do is release the surface tension of the water so it doesn't form droplets on the leaf of the plant. As for a soil wetter, dishwashing liquid is no good.

Useful, thanks! I am just killing weeds, so it's leaf contact, not soil, not using pre-emergent. Most of the worst weeds seem to have hair or stuff to foil herbicide, and it seemed to me that wetter was just detergeant. The stuff the family uses for the orchard is very fancy and expensive and does other things... I just want it ot coat and stick to the weed.

its probably been mentioned already but for your Bryophyllum sp. [Mother-of-millions, Live leaf, etc] Tradescantia sp. [Wandering Jew, Creeping inch plant, etc] virtually any weedy succulents are best sprayed dusk/dawn or at night (were possible) as they transpire at night meaning the stomata are fully open, maximizing absorption.

And were possible irrigate your Herbaceous weeds prior to spraying them - but allow sufficient time for excess water to dissipate to avoid diluting your poison. Same premise as above, it also eliminates the issue with foliage kill and not plant kill. When you just nuke the plant on a hot dry day, so no chemical re-uptake you just scorch the foliage and it just laughs at you and re-shoots.

I've had good kill on virtually everything [except bamboo] with glyphosate [namely the Waterway safe variations] when done thoughtfully. There isn't much else out there that is not a mutagen or carcinogenic.

Obviously only applies were a selective isn't needed.

There is another product that is fantastic, Metsulfuron-methyl... Is very cheap.
lots of generic products available. Can be mixed with other chemicals dependant on what you are trying to eradicate. Is not classified as a poison. And as of yesterday, bloody fantastic on creeping oxalis... Woo hoo!

Metsulferon is my favourite broadleaf killer. Cheap-as, still using a small container of it I've had for ages. I mix it with MCPA and together, they deal with most things. Even St John's, if you get it when young and tender.

Only thing that mix doesn't kill is grasses (which is why I use it), so no good for serrated (which has its seeds on at the moment and is depressingly easy to spot... I've just been ripping it up, mongrel stuff), Wireweed, mature St John's...

It even does briars and blackberry. Great stuff.

Why don't to approach an agri supply establishment and ask that kind of herbicide of as some technicians who are expert on that matter. Don't make your own move with out the guidance of any experts to avoid unremarkable incidents happen.

Huh, have you visited an agri-supply establishment lately? Ask a question, and they read the label. Useless. the only place around ACT that I've found that has a proper agronomist is the place in Mitchell, can't remember its name, might be that "local bloke" mob. The other places though, you have to do your own research and know what you're looking for.

I'd love to know where I could get some proper advice, the internet is actually not good, I spent about 2 hours the other day trying to ascertain whether dicamba really was effective for Wireweed, and got nowhere. So I sprayed the rotten stuff, and now will have to watch what happens.
