    Macro pIcture of a sporophyte

    Had to post this up Folks -
  2. You can drain it off anyhow. Just make sure its medium remains moist. If it was me I wouldn't be concerned about it, I would take it out of the water and just put it straight back into normal conditions....
  3. I'm going for "Submerge the entire pot, everything"! I believe that S. purpurea ssp. purpurea grows in very high water levels naturally, and may be submerged completely sometimes in nature.
  4. And just think how good you will feel if you support the use of something which is not a poison, kills many small pests, and doesn't harm bees or ladybirds!
  5. I wouldn't even try to use the same stuff again if it hasn't already wiped them out. The only conclusion from this (and there may be other as yet unknown factors) is that they are resistant, and whatever you use next, make sure it isn't imidacloprid.
  6. Hmmmm.......... they should all really be dead within 24 hours or sooner.........
  7. Did you dilute it to full strength?
  8. One spray with Provado should be more than enough to finish off an attack of aphids as it's systemic. You shouldn't need to spray anything else now, unless you get aphids there who have resistance. That's the advantage of SBPI, it's not a poison so there's never any danger of resistance developing. If you want to switch over to SBPI once the Provado has worn off, just think, in warm conditions aphids give birth once an hour and are born pregnant. So one may give birth just after you've sprayed, and this offspring survives and continues the infestation. Or one flies in and starts a new infestation. So you may find you have to sometimes spray several times in one day to polish them off. If there's absolutely no danger of bees, ladybirds, etc getting near the plants, I would also probably use something pretty potent. I did recently to get rid of some insidious Brevipalpus mites.
  9. The photo is a bit blurry, but it looks like a bit of leaf-scorch, and also the younger leaves developing the red protective pigment in response to high light levels. As they mature they become green. What are your day and night temperatures in Celcius/Centigrade?
  10. There's one method that says starving Nepenthes forces them to make pitchers from the growing need for nutrients. And one grower thinks Ventrata produces pitchers if it has something to cling to to grow upwards........?
  11. Ah! Thanks Paul. I've had Ventrata for 18 months. It grows like billy-o but produces practically no pitchers.
  12. I am intrigued Paul, which Nepenthes are you keeping outside? Is it really outside all year round?
  13. Whoa Folks! Hold on just a mo! Provado is a neonicotinoid, it's pretty potent and long-lasting, and it kills bees. Well, if the plants are on a windowsill, you probably don't get many bees coming in there? It will get into the nectar and in that way the bees will be poisoned (we have a bee crisis in this country, like in many other countries) It's worth at least knowing about SB Plant invigorator. It is not a poison, it acts physically (so it's also not systemic) It kills many small pests, but does not harm bees, ladybirds, etc. It kills aphids pretty quickly. It is also a foliar feed. To eradicate an aphid infestation, in my experience you may have to spray 2 or 3 times in one day. This is possibly because in "good" conditions they reproduce every hour and are born pregnant. You have to spray it very thoroughly all over every surface, nook, and cranny of the plant. Very important - It is never a good idea to use pesticides at anything below recommended strength. This can leave a few bugs alive, which can then go on to manifest resistance in their descendants. Like not taking your full dose of antibiotics. If in any doubt, it's better to go a bit above the recommended strength to be sure of a complete effect. You can get SB Plant Invigorator on Amazon and eBay.
  14. Thanks Tropicbreeze. Some other responses have suggested too much humidity and/or lack of air movement. One responder suggested using an application of salicylic acid solution to strengthen its immune system. I think the mix it's in is probably too dense.
  15. Got a convincing answer from "Entomology", Facebook - Hypoaspis mites - https://www.facebook.com/groups/TheEntomologyGroup/permalink/10155968915033393/
