  1. * Tested out fluvalinate on a small bridgesii a week ago and to my observation it did not affect the plant. Today I sprayed a pup and a fresh tip growth on the same plant to see if newly growing tissue is sensitive. Pachanoi, bridgesii or peruvianus did not react to this pesticide pup or adult. I haven't tried it on a fresh cut section or very small seedlings, but it looks safe otherwise.
  2. Thanks EG, I am aware of the magnifying glass-effect of the sprayed pesticides/fungicides and avoid it alltogether. I sprayed a small trich to test the effects of tau-fluvalinate and will post again to share the results. As far as I understand certain chemicals (like pyrethrin) can trigger a reaction that results in breakdown of cactus tissue into brown or black mush. My plants spontaneously develop these patches of black blisters with exudates very similar to what people report after chemical applications. Makes me wonder if all cases of "rots" are really due to infections or cacti are just exposed to chemicals that disagree with their tissues.
  3. Hi all, I bought a dual-action insecticide/fungicide mixture containing myclobutanil as fungicide and tau-fluvalinate as the pesticide. I read about this tau-fluvalinate and it turns out that it is a pyrethroid insecticide, meaning it is a different molecule but structurally similar to pyrethrin. I read here that pyrethrin burns cacti but couldn't find info on tau-fluvalinate. Anyone had their cacti burn after using this chemical? Cheers *I went systemic to treat some nasty rot caused by mold possibly due to the long time a cutting spent in postage. I noticed the woody tissue in the vascular bundle was somewhat affected even though the rest of the section looked pretty healthy: This is the vascular bundle after my first cut (notice the darkened woody tissue) And this the vascular bundle after my second cut Do you think this is a legit cause of concern or should I just sulfur it and let it dry ? I heard the remaining fungus can move up through the woody tissue so I would like to make it 100% clean.
  4. Appreciate it man. You can always tell me if situation changes. I also know a guy who can move stuff around for very cheap for me so transportation would be fine. Ah, I suspected temperature to be the main issue as well. I know how much they like full sun and it is my preferred way to grow them. I was hoping a month would not cause excess etiolation because then I have to chop the tips which ruins a column for me. I need to leave for medical issues but once back I am to stay for a long while so no bouncing between garden and indoors.
  5. Hi everyone, I was wondering what can one do to slow growth of trichocereus pachanoi/brdigesii/peruvianus during summer so that the plants do not get drastically etiolated when placed in front of a wall-facing windowsill? I already plan to withdraw water until the pots are bone dry, but since the temperature is going to be high overall I am not sure if this would halt the growth completely. I am going to be leaving the Oz for a month and I cannot stand the thought of my plants being stolen, therefore I will lock them in my room in front of the windowsill. With all being said, I would also be more than happy to transport my plants if someone is willing to keep an eye on them in a surely safe place and would gladly give away a good number of cuttings in return
  6. Thanks CJ, As far as I remember he only mentioned seed pods with no seeds in it. It might hint of some self-infertile species. As far as I know williamsii fits that definition but have no idea about fricii and koehresii. The latter are very rare though aren't they? I would be surprised if they turned out to be those species. Also this link decribes a variation called "decipiens" and the plants fit the description quite well in my opinion. http://sacredcacti.com/blog/decipiens/
  7. Hello everyone, A friend of mine overseas sent me these pictures of degrafted and rooted lophophoras which he bought for an amazing price (around 25 bucks each?). I was rather suspicious since it sounds too good to be true so decided to ask if these are just some of the more common lookalikes out there. The three heads in the photo are approximately 6 cm each and the one with the roots is around 5 cm. The ribs are clearly defined but these do not look like any of the classic williamsii's I have seen on the web so far. Unfortunately I don't own any so I can't compare. Any of you guys know if this is a particular variation of williamsii or another species altogether? Thanks in advance!
