PositiveHAL Posted February 4, 2012 (edited) Hi all, im Negative Dave from Melbourne, a little about me, ive been growing cactus casually for over a decade, but just now im getting right into grafting after rescuing my 10 year old monster peyote graft that has been looked after by my relatives while ive been travelling. To my shock its gone rapidly down hill in the past year, its almost detached from the trich rootstock, has had significant rot and lost buttons, has an ant? colony living in its guts, and is generally unhappy, ive acquired some peres and trichs/myrtles etc, for some rescue grafting but out of the 1st round of trich/myrtle grafts am not having much luck might be lucky to have 1 take, im about to graft some of the smaller peyote offsets onto peres. Anyways i just secured and awesomely frickin' huge Trich. pervianus? (confirmed I.D appreciated) with a 5ft and 4ft thick columns, woo hoo!, in addition to a heap of soil grown short spined t.scops(confirmed I.D appreciated) and a slightly longer spined scop. Any way im keen to go along to the upcoming Melbourne gathering i saw on here recently and meet some local peoples, feel free to to message me if you're local and interested in meeting up for a graft fest or plant swap, etc. Cheers, Negative Dave EDITED BY MODERATOR: NO COMMENTS ABOUT INGESTION!

PositiveHAL Posted February 4, 2012 lots more pics if anyones interested. plus im in need of a fair bit of advice/ questions answered. Cheers, Negative Dave Share this post Link to post Share on other sites
zahsone Posted February 4, 2012 Welcome mate, was that peruvianus the one from northcote by any chance? The lighter green one in front of the stack of scops looks like a pach to me Cheers Share this post Link to post Share on other sites
PositiveHAL Posted February 4, 2012 sure was! very local to me Share this post Link to post Share on other sites
zahsone Posted February 4, 2012 I used to live just off high st, looks like you got a good buy on that one Share this post Link to post Share on other sites
PositiveHAL Posted February 4, 2012 "The lighter green one in front of the stack of scops looks like a pach to me" The huge scops ive had for over 10 years, grow like mother fuckers when planted in the garden, got them from a well known cactus nursery in the hills district of Sydney, thats what the old peyote is grafted to, that other one in the front of the photo (below) is one i got from an old lady the other day, it seems identical to my almost spineless scops, dont know about it being a pachnoi? what do you guys reckon Share this post Link to post Share on other sites
PositiveHAL Posted February 4, 2012 here is another pic of the peyote graft, its barely attached and wobbles like a loose tooth, really dont know what to do with it, its heart breaking, its been so glorious for years, it was probably twice the size a couple of years ago but rot had killed 1/2 of it. the above picks after i cleaned it all up and removed all the rotting buttons and decayed tissue, also here is a pick of some smaller pups that got severed in the clean up process. These will hopefully go on the peres, but each day ive gotta throw more out due to rot, some of them have tiny roots though. would a "lime sulfur" drench or a "anti rot" phosphonic acid drench help??????

dionysus Posted February 4, 2012 id say almost without a doubt that that lighter green one in front of the scops is PC pach Share this post Link to post Share on other sites
Evil Genius Posted February 4, 2012 Would say Pachanoi too. Ever checked for spidermites? Rot looks this sometimes caused by spidermites (and/or the Ants you mentioned). Rot looks a little bit orange so that could have been orange rot but it doesnt look like a typical infection to me. Got more pics from the original rotting Loph? Because the thing that caused the first Loph to die might find great growing conditions on the new grafts as well. It might be more successfull on the long term to get to the bottom of it before you lose the others too. Sulphur sounds like a plan to me. bye Eg Share this post Link to post Share on other sites
lhb2444 Posted February 4, 2012 I'd have to agree on the PC pach, looks exactly the same as my PC pachs. Share this post Link to post Share on other sites
niggles Posted February 4, 2012 hi dave and welcome! geez mate that loph looks sick! I live in coburg, prolly not far away from the sounds of it.. you should come round and play sometime, sounds like we share interests Share this post Link to post Share on other sites
PositiveHAL Posted February 4, 2012 Sure Niggles send me a PM, would love to. I was into this long before dedicated forums and knowledge was easily available on the net, so im reallly liking this, i guess im a bit of a late comer. ill probably be annoying you all with multiple posts in the coming days, until i can get to the bottom of my ID/pest/disease problems. BTW what is the PC in PC pachnoi? Share this post Link to post Share on other sites
PositiveHAL Posted February 4, 2012 No ones commented on the peyote being potted in the 9litre green bucket!! complete with drainage holes randomly stabbed with a set of felcos... like i said earlier things are very desperate for my once glorious peyote. Help is needed Share this post Link to post Share on other sites
dionysus Posted February 4, 2012 PC stands for predominant cultivar, http://www.largelyaccurateinformationmedia.com/pedro/pedro.html has some information about some controversy surrounding this particular cactus. welcome to the forums by the way man, good luck saving some of that loph. looks like it would have been pretty impressive pre-damage. dionysus Share this post Link to post Share on other sites
bit Posted February 5, 2012 Welcome to the forum! Your peruvianus might be the Australian T. knuthianus - I've never owned it so can't be sure, but it resembles the other photos of knuthianus on this forum. As for your mother loph - it looks like it needs some serious intervention. I would be looking for a fungicide / insecticide to submerge it in for 30 minutes or so. Then let it thourougly dry out in warm dry conditions, and plant in fresh soil. You definitely need to get rid of the ants as a first step. Share this post Link to post Share on other sites
PositiveHAL Posted February 6, 2012 cheers bit, knuthianus? hey, just when i thought Trich ID couldnt get any more complicated!!!, some serious taxonomy work needs doing on these plants!!!, thanks for the advice regarding the Loph, what fungicide specifically would you use?

Chef Posted February 6, 2012 Hey man, welcome to the forum.. sorry to hear/see your loph i know how much they mean when u lose them after years of growing them Share this post Link to post Share on other sites
Evil Genius Posted February 6, 2012 (edited) Im not an expert on fungicides so maybe someone else could throw in some names of chemicals that work but arent cancerogen. Im looking for some good ones myself. Chinosol is a name that is mentioned oftenly but i have doubts about its effectivity. Some cactus growers i know use orthocid but its cancerogen so its pretty much out the question. Also they changed the name so i dont know how its called these days. Anyone ever tried the sprays for foot-fungus on cacti? I mean, they shouldnt be cancerogen or they wouldnt be allowed for humans and they should work against fungal infections. You could also try Povidon Iodine. Never tried and Loph might die but chances are cacti do fine with it. bye Eg Edited February 6, 2012 by Evil Genius Share this post Link to post Share on other sites
PositiveHAL Posted February 6, 2012 'foot fungus' that reminds me of a greenskeeper i once knew, whenever he had a case of tinea (in the 80's) he used to just go barefoot on the golf greens when he was spraying fungicide. cleared it right up he'd reckon... this is the same guy that got banned from spraying ANY chemicals at our workplace after bloodtests revealed that he had unacceptable levels of pesticide in his system.... but anyways, generally all of the pesticides/fungicides on the market are suitable for food crops/veges,etc as the long as the 'withholding period' is adhered to. In other words we are eating all the time anyway. Im thinking of using a 'Lime Sulfur' spray/drench as im guessing its more pH balanced than a purely sulfur based spray/powder (possibly too acidic), or else a phosphonic acid drench which is quite a strong and may be a bit drastic?? any thoughts? experiences? 1 Share this post Link to post Share on other sites
bit Posted February 7, 2012 Yeah, sorry I have like zero experience with fungicides myself (much less with lophs given their legality over here), but I'm sure other members here have used them as I remember reading stuff about how to deal with rotting/damaged plants - hence my advice.

niggles Posted February 8, 2012 It was great to meet you negativedave! Thanks for being so generous with your supplies, you have sorted out my pot problem for some time to come I'll be in touch for another catchup soon. So good to have another member with such useful plant knowledge, and not far away. Share this post Link to post Share on other sites
PositiveHAL Posted February 8, 2012 Aww, thanks niggles, and same to you, thanks for inviting me into your cactus paradise, your collection is most impressive and inspiring!! im still blown away by those huge lophs! head round mine for a bevvie on the balcony some time Cheers NegativeDave Share this post Link to post Share on other sites
paradox Posted February 15, 2012 Your peruvianus might be the Australian T. knuthianus - I've never owned it so can't be sure, but it resembles the other photos of knuthianus on this forum. i thought that too when i first glimsed it but i don't think so. i can't remember who gave it to me but quite a few years ago i recieved a cutting from a member here labeled T. peruvianus that look absolutely identical to negativedaves plant. i always wondered about that plant because it's distinctly different from most peruvianoids in a number of ways.. it looks like some kind of aussie knuthianus/peruvianoid hybrid or something.. deffinitely shares ALOT of similarities to oz knuth but is also distinctly different. oz knuth tends to drop it's spines quite quickly often leaving just the two downward pointing spines. this peruvianoid hybrid thing keeps all it's peruvianus-like spines. also, oz knuth also tends to have distinctly thinner columns.. i have seen large oz knuths in the ground that have much thinner columns than the peruvianoid i have that's smaller growing in a pot... that said, you might be right cause it definitely looks like it & it's a little hard to be certain from the pic Share this post Link to post Share on other sites
PositiveHAL Posted February 15, 2012 anyone know about this cactus: Azureocereus Hertlingianus could this cross with a trich to result in what ive got?? i havn't thought this through, just stumbled across it then, nice looking btw Share this post Link to post Share on other sites
