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.

So how did it go ant? Dicamba works on wire weed really well but the addition of MCPA gives it a double whammie..

I loaded up the 50 litre drag-tank with a super mix of dicamba, mcpa and metsulferon! Went out and hit everything except serrated. This was a few months back. The verbascum and fleabane in particular were rampant and about to seed but everything was at-it. Did a largish quadrant with 2 tanks, about an acre or so. Then my damn pump went bung and my brother is still fixing it (just seals and things, the pump's OK now), there's still a quarter of a tank of mix and it must be stale by now.

aaaanyway, after a week, that acre was looking pretty sick, after a few weeks it was like a war zone. Nothing but the grass survived. Savage stuff! And where I hit wireweed (that's around the house mainly), it seemed to hit it pretty good. Hard to tell with wireweed but I was pretty happy with it, figure any that survives you just hit it again and it will be so weakened that it'll work.

Busted pump though really stuffed my last assault on the fleabane, so now i'm going to have that stuff until we have another drought.

Sounds like a good result then fella... Well done and bad luck also...

I cast an eye down the hill this morning on my way out, at the Acre of Death, and what is also nice is the lack of weed re-growth. I haven't seen it like that in ages, and you can really tell the difference from the areas I didn't get to. There's a couple of old logs where the weed community has been shocking since the early 90s, you get successions of lush growth. All gone. That poison mix is definitely a winner.

Granulated urea works a treat on sensitive weed. Simply sprinkle the granules around the roots. It stops regrowth also for quite sometime and has the added bonus of fertilising.

Thats only fertiliser burn!! you might as well piss on them because thats concentrated urea anyway!!

I am NOT fertilising 10 acres of weeds.

Chuckle......

That granulated urea might be useful for my lemon tree though (not weeing on THAT, either). It sat there under the deck for years, zero lemons. Then I bought a bag of citrus food and put it on (killed the grass around it) and bingo, lemons. The minute the frosts are finished, I'm going to go crazy with it and make that lemon tree earn its keep. lemons are expensive these days.

Actually the place isn't looking too bad, barring that fleabane which is all breaking down now. The only weed hanging around is that nightshade one with the little black berries, that's popping up in colonies where the birds poo. Totally dominated the St Johns Wort this year, and the Patto's never really happened.

Careful with the urea Ant to much and it will bolt to growth and not produce fruit, mabye a mulch of lucerne hay and stay with the citrus food- what type of lemon by the way.

I think it's a Meyer, they are the ones that do OK around the ACT. It's got the perfect spot and has no excuses. I'm eyeing a spot near it to try a Tahitian Lime, they're tricky here but do-able. Lemon will have to be happy with the bag of citrus food, I mulched up some prunings so that's its mulch. Lemons turning yellow! Damn thing is about 10 feet high or so, about time. no more bludging.

Ant my lemon is a Meyer it took a while to get going its been growing for 5 years and gives us and the neighbours more than we need i keep it pruned to 1.5 metres. we dont leave the fruit on to long so as it keeps flowering gives us lemons most of the year. ...................GDL

Ah, pruning. I haven't thought about pruning it. It is a funny shape, and the best lemon sections are the twiggy branches right at the bottom of it. I'm eyeing some of those low-down lemons, as they're almost fully yellow now, and soon will harvest my very first lemons ever. It seems to have some flowers coming on, but you're right, getting the fruit off should give it a bump along. Need Moar Lemons.
