[IBC] Clues on Fumigation
"Claudio Fierro" wrote in message ... I have two questions about fumigation: First; is it right to make it in a preemptive way? If so, could anybody explain me when to make it and agains what kind of insects/fungi/spiders/etc and with what agents? And another question about the use of oil based pesticides against spiders and aphids: Is it safe for our bonsai to use them? Does it affect in any way our soil if it becomes wet with that kind of solution (maybe the water retention?)? Thank you all. Don't apply any chemicals unless any targets are there. Applying it before you see the targets can/eventually will cause resistant pests/fungus and then you will have all sorts of problems. Oil based pesticides are safe to use, but careful when using white oil/pest oil, a petroleum based spray used to suffocate pests, mostly spider mites, aphids and scale. As a bonsai is so small, it is quite easy to cover all the foliage, which is needed on the topsides of the leaves, but careful not to cover undersides of the leaves as it can suffocate the plant. Some chemicals will become inert when it hits the soil, others may stay in the soil for 6months, you have to read the instructions to know what's what and the effects it has on soil. They won't harm the plant, but careful with the soil for your own safety. Finally mix at the suggested rate, don't weaken it cos a bonsai is small. Most of all follow instructions carefully, especially taking note that the plant isn't waterlogged, soil extremely dry, or suffering from heat stress at time of application which are common rules for most chemical applications. Good luck Claudio Fierro Neudörfer ************************************************** ************************** **** ++++Sponsored, in part, by Chris Cochrane++++ ************************************************** ************************** **** -- The IBC HOME PAGE & FAQ: http://www.internetbonsaiclub.org/ -- +++++ Questions?

[IBC] Clues on Fumigation
I don't have much to add to what you've already been told. I can't
tell if you really meant "fumigation" as in "applying a pesticide in gaseous form", which is a bad idea, period. (Claudio Fierro) wrote in message ... I have two questions about fumigation: First; is it right to make it in a preemptive way? No. And another question about the use of oil based pesticides against spiders and aphids: Is it safe for our bonsai to use them? Test first. Trees differ in their sensitivity to oil; the dosage to use may differ. And read the label: some should not be used above certain temperatures.
