Glyphosate experiment

[@BaaBaaBoozeHound]

This really is a game changer for the masses who can't get a hold of those pesky weeds, IF DONE PROPERLY.

[@lawncarewithtim4896]

Excellent video, and the way you show us your own experiments. We all love experimenting on our lawn and anticipating on the results.

[@theaussielawn]

Thanks mate much appreciated

I had a suspicion that it would work as I use a similar technique quite a lot when using glyph, this is mainly to target a particular species of weed and keep the desirable grasses, though I use it more commercially that for amenity turf. It’s getting the balance right between the rate to kill the target weeds and the rate to kill the couch plus a whole bunch of other things to consider along the way. Definitely one for those who know their way around a roundup bottle! As it’s real easy to get wrong. Another way I have seen it work is when it rains just after spraying. The rain dilutes the concentration and you end up having to spray again because everything gets sick but it doesn’t kill it. Great work and thanks for actually going through with the experiment, well worth it

[@theaussielawn]

Yeah I did it as an apprentice about 1000years ago now cause that’s how we controlled kikuyu back then but we used 1/4 rate 360

[@TW-pm8lc]

Loving the channel mate and can’t wait to see some of your upcoming projects!!

[@theaussielawn]

Thanks mate

[@TheBertjeT]

Passerby viewer here. The concentration of the concentrate doesn't matter does it? Whether it's 10 or 900 g/L. You would just end up using more or less concentrate do end up with the desired spay mixture right?

[@theaussielawn]

Hi Bert you are 💯 right mate, It was more of an angle of not recommending off label use on here thanks for stopping by too Cheers Brenton

[@TheBertjeT]

@@theaussielawn Ah I see, thanks for the clarification. And great job on viewer interaction ;)

[@theaussielawn]

@@TheBertjeT Your most welcome mate, one final point re the glyphosate rates. if the product is less concentrated in the bottle to begin with it also means you have a little bit more of a safety gap for measuring if your dealing with 1/4, 1/2 rates etc of "full rate products"

[@ithertzz]

Mate once the paspalum has hung its hat, what's the best way of pulling it out and getting the couch to return? Dethatch? Scarify? Hand pull and top soil/seed?

[@theaussielawn]

Dig it top dress the barespots and fertilise (to encourage your couch to spread), Id also consider using a pre emergent herbicide too such as Barricade

[@ithertzz]

Thanks mate. I've hit the paspalum with monument already and a second hit spot spraying with monument also. Have put barricade down on the whole lawn and the paspalum is definitely dead and grey. Some of it still purple but it's on the way. I think now I'm facing some pythium issues and where I spot sprayed monument some of the Qld Blue has been knocked a bit too. One problem after another 🥺

[@warrenwilliams334]

Hi mate. I have a long garden bed with lomandra Tanika and the kikuyu made itself at home in the bed around the plants. Do you think this would work around the lomandras. If a little bit got on the lomandras do you think it would kill the plant or just the kikuyu?

[@theaussielawn]

Google search a chemical by Syngenta called fusilade it might be a better solution or if u want to try the glyphosate just trial a small section and see how you go. I suspect it will be ok but I’d still be ultra careful to avoid contact with the lomandra with glyphosate

[@shanebenton3748]

Very interesting. I got some on my windsor once. It yellowed but didn't die. I always thought quarter or half strength dusted across the winter grass would be effective! Good vid mate.

[@KurtsReviews]

Great Video mate, I have santa ana couch that is being invaded by Kikuyu (about 40% worth) do you have a recommendation for my lawn specifically? Or because i have lost alot of it to the kikuyu, (my lawn is cut in half by a path through the middle of it) would it be worth going ahead with this stuff, then doing a reseed when i do my spring renovation (2nd time doing it properly)

[@theaussielawn]

Hey mate, unfortunately you can’t purchase Santa Anna seed as it like most improved varieties of couch grass is in fact sterile . It’s a tough one u have there . Perhaps tribute by Bayer may help in your situation. But just check the label first .

[@kurtwhittingham7015]

Hey mate, so i ended up going with Momentum and worked a treat, killed off all Kikuyu (some is come back naturally but small amount in a spray bottle is keeping them away) couch wasnt affected, grass is coming back killer!

[@zacj63]

Hi, Brenton. Can you advice me how I can get rid of paspalum in my Kikuyu lawn? I have lots of it.

[@theaussielawn]

Hey Zac your new best friends will be a paintbrush and some glyphosate and paint each one individually unfortunately.... Good luck mate 😩

[@zacj63]

Thanks mate i will do that👍👍

[@petercooper5160]

Another great vid mate... I reckon go with Green Lees Park when you replace the couch. I have Green Lees Park in Cairns, currently mowing at 8mms, it’s coming up nice.

[@theaussielawn]

Thanks mate yeah Im leaning that way atm although it would be nice to have a little bit of tiff tuff just so i can learn about it and help others down the track if they need advice on it. (atm i have a small section off tiff tuff about 3sqm just for the heck of it)

[@paulthomas3782]

Hey mate great video thanks for taking the time to conduct the test and sharing. I have an area of Paspalum in Queensland blue couch, and have just applied Tribute with trigger sprayer 3 days ago hoping it won't kill the blue couch to bad?

[@theaussielawn]

It’s not ideal mate so hopefully you got most of the chemical on the paspalum. Depending on how much paspalum u have you can always dig out or paint on with paint brush

[@darrtoo5767]

Paul Thomas Hey Paul, I use Tribute to knock over Qld Blue from Common & Wintergreen Couch. It doesn’t work as quick as DSMA but it does gradually get it over a couple of weeks.

[@paulthomas3782]

[@Hahehhwgajshah72726..]

Great video.Any tips on getting rid of green couch in kikuyu or at least suppressing it without costing a fortune? Cheers.

[@theaussielawn]

G'day mate, unfortunately there isn't any chemicals I'm aware of that will kill green couch out of a kikuyu lawn leaving only the kikuyu.

[@leightonsmith5302]

Awesome tip mate. I would not have thought about that. Very helpful because I’ve got some kikuyu ravaging my wintergreen that is about to meet its end I reckon

[@theaussielawn]

Just be careful with it mate less is more.. this approach is not for the faint hearted

[@darrtoo5767]

Leighton Smith I use Dicamba to knock out Kikuyu in Wintergreen.

[@Crocxr8]

Nice video. I have some buffalo grass I need to get out of Santa Ana, was thinking of doing the same. Do you think the couch would've faired better if you'd left this until a bit further into winter when the grass would be more dormant?

[@theaussielawn]

Yes it would have faired much better . Just note that Santa Ana couch will not tolerate this sort of approach. Best advice I can give you is find a product that says not suitable for buffalo turf and apply that. From memory Kamba m (broad leaf weed control ) herbicide states not for use on buffalo however it’s safe for couch grass and will control bindi clover and broadleaf weeds

[@Crocxr8]

@@theaussielawn Thanks mate, good to know. Coincidentally, I actually just sprayed some Yates Bindii and Clover weedkiller earlier today to see if I can get rid of some Clover and Oxalis. It's Diacama and MCPA based, so hopefully it'll give the buffalo a knock too. If that doesnt work, I might still try some glyphosate later in winter, fortunately the buffalo is reasonably well separated, so I can be pretty selective.

[@theaussielawn]

Crocxr8 keep me posted mate I’d be interested to hear how you go. Thanks for subscribing 🤘 Your a legend.

[@johngrear6506]

Interesting idea and a success :-)

[@theaussielawn]

Just make sure you only try it on the 3 varieties I mentioned as I don’t know what others will work

[@theoneandonlyowl3764]

Bloody khaki weed was a menace when I was a kid. A good clump didn't look much different to carpet weed, which we'd jump on to cool our bare feet, especially when out in full-prickle. A bit of toss up on which is better to run through, bull-heads or khaki weed, lol.

[@theaussielawn]

Haha that is a hard one hmmm 🤔 they are both as evil as each other 😂

[@BigLeafDropper86]

Very interesting, great video

[@theaussielawn]

Thanks Warwick 🤘

[@Pajeroecosse]

Great work mate. Best way of removing kikuyu in sapphire buffalo?

[@theaussielawn]

Unfortunately as far as I’m aware there is no selective herbicide for that situation. If u only have small sections. Get some glyphosate and a little paint brush and target the kikuyu runners . Larger area you might have to spray the section out with glyphosate and replant some buffalo runners there. But wait till spring for that

[@Pajeroecosse]

Perfect I’ll do that thanks very much

[@donslawns1]

So I’ve actually heard of using glyphosate at low rates as a PGR on Bermuda. Wild to think about, right?? I guess the grass is just too strong.. lol

[@theaussielawn]

Don’s Lawns as far a invasive grasses go I think it’s ranked number 2 in the world pretty crazy when u think about it hey 😳

Hi mate.Just found your channel.I used glyphosate 360(Hortico) to kill kikuyu from my couch at 5ml per litre in mid winter with great success.

Fabian Sosa welcome to the channel mate glad you found it. Good work on the glyphosate kill . 🤘

[@darrtoo5767]

Another great video Brenton. How do you reckon it’d go knocking over Buffalo & Qld Blue out of Couch? They’re pretty weak when it comes to certain herbicides.

[@theaussielawn]

It would depend on the couch variety. A safer option would be monument herbicide

Great video mate, I liked the experiment considering Kikuyu tends to get in my couch and felt like I needed to accept the outcome - not any more! 👊

[@theaussielawn]

Just make sure you have one of the 3 varieties I mentioned and wait till winter 🤘

[@nathanwotwot]

Interesting video. Do you think the Kikuyu that survived will be more resistant to glyphosate now? Also is there a way to control khaki weed in couch? I'm lucky that I don't have it in my lawn but people in town have it and it's horrible.

[@theaussielawn]

The short answer is no, the long answer is potentially, the plant would need to be subjected to low doses of glyphosate over a period of time for it to start building some kind of resistance. I would suggest something like Kamba M is a good choice for control of the khaki weed in your couch lawn. Its a shocker the only thing i can think of that's worse are cat heads.

[@nathanwotwot]

@@theaussielawnwe call cat heads doublegees here is the west. You are right though, they are way worse.

[@booobface]

Good stuff mate. I’m a buffalo bloke but I wonder what the bounce back time would be for that with regular watering and fert? Especially around spring time and would you get more paspalum forming in that time?

[@theaussielawn]

I wouldn’t recommend doing this to anything other than a couch lawn mate and even then as a last resort in the depth of winter. Get it wrong and you have just killed your lawn

[@booobface]

The Aussie Lawn Fair enough mate, what about on your patch there?

[@theaussielawn]

Brendan Craig it’s just a little experiment I have had years of practice at this sorta stuff and I sorta just have a feel for how much chemical I want on the grass blades so I’m comfortable applying it earlier than winter. I’m also not to worried if that area did die as come spring I’ll be turfing all that side of the yard.

[@theaussielawn]

I might have misread your first comment do u mean you want to try it on your buffalo?

[@booobface]

The Aussie Lawn no sorry, I meant on the couch haha

[@walter8008]

Nice experiment, never thought of trying it this time of the year. Could you do a follow up vid in a month? Only asking as we use it on the course roughs in July at 1/4 rate and whilst it browns everything off the greenleas park bounces back and so does they kyke. Completely nails wintergrass. Actually any drift onto the greenleas fairways doesn't affect them as the wintergrass is so thick is shields the couch from the spray. But yeah, just keen to see if any of the targets green up. It definitely cleans things out. Greenleas is tough as nails but I may have accidentally found its enemy this year. Task force herbicide

[@theaussielawn]

Yeah absolutely happy to do a little follow up. Way back in the day (1000years ago 🤣) when I was an apprentice I did the 1/4 rate trick to deal with kikuyu in couch that’s what we used back then . We did it on both greenlees park and Windsor green couch it’s what we did back then before monument etc

[@theaussielawn]

walter8008 too kind mate. Thank you 🤘

[@djdescent]

The green keepers i used to work with when i was a gardener used to say that round up diluted a 1ml per litre works as a pgr. Guess its got a few uses
