  1. If I remember right this discussion began a few years back when a 'disease' swept through vft collections in Europe. A certain amount of panic arose about it being a virus. At the time I doubted it being a virus and it was eventually confirmed it was a bacterial/fungal infection (i cannot remember which). IMHO it is not a virus in 'Patches' and I have done many many tests trying to cross infect etc. These plants grew happily with many other varieties for nearly 10 years without a problem. In all this time the patches were always within the traps, never on any other part of the plant. I also had patches on traps as small as 4mm. It seems the amount of nutrient within the growing media affected the patches production. The older mix without fertilizer produced the better patches. Geoff
  2. Hi Dmagnan, No offence taken. I also do not jump to conlusions without the proper evidence. I have not sent plants of 'patches' away for virus indexing in the past. I have done this with other plants. Hmmm 10 plants is a lot and will deplete my stock quite a bit. I was thinking of making a slit in the mid rib of the leaf and like you said paste it over the cut with the mash. Another idea was to use this mash and add it to some water with a little sugar maybe and soak the host plant/s in it after making some slits in the bulb area of the plant and then replanting. Oh! one other point I am also a cp nursery and try to keep 20,000 vft in stock at any one time so I do have a vested interest as well. Geoff
  3. Hi, What my main gripe is the fear, ignorance and crap generated without any proof whatsoever that 'spotty' or 'patches' is a danger to our vfts existence. There has not been 1 test done with these plants, except what I have done in tc and general propagation. I am only talking about 'patches' here, I do not own a spotty. For the sake of the debate. I will do the tests. In the past I sent plants away for virus indexing. I will do this again and I will try to infect a few different varieties of vft. I have not done this before so I presume all is done is a cut is made on the host plant a cut made from the donor plant and while as fresh as possible these are rubbed together. Is this correct? I will post pictures of every step along the way and everyone can have imput. Will this keep people happy? Geoff
  4. Hi Phil, I swore to myself I was not going to get involved in this hysteria. However in answer to your question. The answer to your question. It is very unlikely for a tc plant to catch a virus in tc but as we know anything is possible. I wouldn't like to guess how many plants were cloned previous to this from the same stock. When multiplying a plant I would maybe obtain anywhere from 20-30 plants from 1. Now, I would think if one of these was virus infected I would have 20-30 virus infected plants seeing they were cloned from the original. In the case of nepenthes I have had a clump of ventricosa x truncata all still attached to the mother plant and 1 of them variegated and the others normal. There is always the case where I may have introduced the virus myself but this is slim. I have 2 certified air flow cabinets. Also if the so called virus was virulent with the cutting process in tc it should have contaminated the whole flask it being an ideal breeding ground for such things. You have basically answered your own question with your statement: Or perhaps a genetic mutation in this clone, made it susceptible to showing up a virus ? I believe this is correct it is all down to genetics. The genetics of 'patches', 'spotty' and every other vft makes their individuality. The genetics of 'patches' allows this plant to be what it is whether it is virus induced or not, it is still the genetics that allow this. There has been enough written over the years about us humans and genetic traits for illness (cancer etc) not to mention the obvious, color of eyes skin etc. The trouble is mainly the word virus. People hear this word and panic. We all have viruses in our body every day, it doesn't mean we are sick though. With 'patches' for instance the genetic makeup of this plant makes it what it is. If it is a virus that makes the patches it does not necessarily make it sick. I would also bet my left and right one that other vfts will NEVER be infected by this so called virus because they are genetically incapable of allowing it to take hold. If this was the case every plant on earth would be at risk from a variegated plant, and this is just not the case. I have had variegated Philodendrons in the past where the instructions are to cut off any green leaves to maintain the variegation. I read with horror the other thread where 'spotty' was blamed for a virus spreading through vft collections. I knew instantly it had to be a fungal or bacterial infection. However people jumped to the worse conclusion, poor ol' 'spotty' burn it at the stake. Then some very intelligent person decided to get their plant tested and the fungal culprit was found and treated. As for the leaf cutting not carrying through the traits obviously it interferes with the process this does not mean anything bad it just means it remains valuable. One final point. As previously said there are viruses which will kill plants and humans stone dead. We all carry the herpes simplex virus not everyone has cold sores. My view is enjoy your plants and don't worry too much about this. If you are concerned get them tested. It is our choice what we buy and don't buy. Geoff
  5. Please let me know when the prosecution rests and all variegated plants are found guilty of being different and they are to be burnt at the stake. I know the complete history of 'patches'. I was planting out a number of 1,000 vft from tissue culture and noticed it. This was the only plant that had the patches. Karl found his plant in a store and I would safely assume that it also originated in tc as well. In fact I would bet that most 'new' vfts were the by-product of tissue culture. Over the years I have had a few nepenthes turn variegated in the flask. These are plants I have had for years in tc. Every now and then something happens to the cells of the plant during the multiplication stage with the added hormones. I have heard stories of people taking flasks/seeds to the dentist and getting them x rayed to induce mutations. I personally do not know if this works. There must be plenty of places for virus indexing to be done in Europe. It is fairly cheap. Big nurseries do it all the time. Geoff
  6. Yes Jens does have a few of these plants, 2 are already spoken for the rest I am going to use as swaps. So if anyone has anything to swap contact Jens. As for the sale of these I have decided to auction on ebay 6 plants, 4 for the Northern Hemisphere and 2 for Australia only. I have never auctioned a plant before so constructive comments would be appreciated. I figure the market will set its own price and this is the fairest way. I am thinking 4 auctions and the person who wins a plant cannot bid on another so 4 different people have a plant. I already sell a few plants on ebay under my nursery name Living Traps and the auction will be under this name. http://cgi.ebay.com.au/Venus-Fly-Trap-vari...=item3a605b9f0c Geoff
  7. Hi Jens, make sure you keep them alive with all the cold weather you are having. I do not know how people can live with minus 9C. Maybe nice to visit but I would hate to live there. Geoff
  8. Hi Thomas, Seeds are viable and do germinate. Plants are growing well but are still small and I haven't noticed patches yet. The only vegetative propagation I have done is by back bulb division. Plants do retain their patches by this method. The main reason for not too many plants being available is I only had 1 plant originally and being desperate for 2 plants (safety in numbers) I did a back bulb division while the plant was quite small. I nearly lost both plants and for 2 seasons they sulked until they began growing again. Also there is a question of priority and time. Running a nursery etc is quite time consuming and the 'patches' always seems to get pushed to the bottom of priorities. Patches is not the typical 'mutant' vft it is a vigorous grower and has no deformation in traps or leaves, it is no where near like 'spotty'. The patches are only inside the trap and no where else. Basically it is a normal vft (whatever normal is ) it is just that the pigmentation within the trap is erratic. Geoff
  9. For those of you who may think I may be misleading anyone here are some pictures I have literally taken 20 minutes ago. The traps are still young and are still forming their patches. The vft's they are resting on are B52's. Geoff
  10. Hi, Ok everyone let's have some input here. What is a vft patches plant worth? How do you put a price on something like this? This is the problem. People have asked why has this plant not been introduced into the northern hemisphere? Answer: Lack of plants, Lack of time and complicated phyto procedure. Just to refresh your memories here are some more pics. I am looking forward to the discussion. Geoff
  11. Karl. They grow the patches all growing season. Geoff
  12. Hi, The patches appear on all the traps. In the picture the traps without the patches are new growth and they color up as they mature like a normal vft. Geoff
  13. Hi, Yes I still have this plant. Just a quick update. I found my plant in amongst a few thousand vft ex tissue culture. I have been growing and testing this plant for over 5 years now. I did place it in vitro by seeds and by plant material. The seeds did germinate and I was successful with the plant material. Unfortunately I mixed them by accident. I have just planted some out and it is too early to tell if they have the patches yet. I did email some pics to Pete yesterday. I think he is going to post them. Geoff
  14. Here is the MDS sheet: http://www.accensi.com.au/msds/Country%20C...rifos%20500.pdf I would only use this product once or twice a year. Geoff
