If you look up http://extoxnet.orst.edu/pips/imidaclo.htmimid, you will see it is not to go into your martini mix. since not sprayed, is not real bad. wear gloves. It is indeed a spray... As long as we are nitpicking. Regardless of whether it is a systemic or not. At least in most applications it is applied as a spray, and you can even buy it in a premixed version for that purpose, with it's own hose-end sprayer... http://tinyurl.com/nd6yd. I apply the bayer 'spray' or whatever you want to call it as a drench. With a hose. I don't like dipping plants, you can (supposedly) transmit virus or other pathogens that way. Unless you change your dipping solution between each plant, and I'm not doing that. I doubt that communal dunking is a major vector for viral transmission, but I prefer the 'better safe than sorry' approach. There is a 'translaminar' formulation (called Marathon II, I believe) which will actually enter the plant through the leaf. But I can't afford it. When saying it was 'safe' I meant in relation to nicotine... I concur that you don't want to put it in martinis (I prefer beer, anyway). Most pesticides that you can buy off the shelf these days have very high LD50s, in other words, it takes a whole lotta product to harm you, and you would probably have to go out of your way and either bathe in concentrated solution or drink it neat. In this case, the LD50 for mouse is 131mg/kg, and rat 450mg/kg (interesting difference!). http://tinyurl.com/kqbr4 That means my portly self would have to consume about 13 grams of pure compound (assuming I'm a mouse) for me to have a 50% chance of kicking the bucket. Doesn't mean smaller doses wouldn't hurt, though, and for that reason and many others it is common sense to use protective clothing when applying anything. Even fertilizer, really. Just for kicks, the oral LD50 for nicotine (in the rat) is 50mg/kg. And 140mg/kg for dermal (through the skin) contact. And the MSDS says that it is very readily absorbed through the skin. Yikes! -- Rob's Rules: http://littlefrogfarm.com 1) There is always room for one more orchid 2) There is always room for two more orchids 2a) See rule 1 3) When one has insufficient credit to obtain more orchids, obtain more credit |

Oh my, sorry to hear that you have this problem, I damaged my esophagus a year ago,
accidently breathing in exhaust fumes! You are going to have to go the natural way, using predators, like LadyBugs etc. Hope you find something. -- Cheers Wendy Remove PETERPAN for email reply mmccaws2 wrote: Hi Wendy7 It is lung tissue permeability to VOCs. So, depending upon the chemical, alcohol, aldehydes, benzenes, acetones etc, I will take on the symptoms as if exposed directly to a strong dose of that chemical. Symptoms like fatigue, head-aches, dizzy-ness, loss of balance, breathing restrictions. And depending on the exposure, and I'm talking about doses that people find annoying when a little old person slathers it on,lotion, perfume, or fabric spray, I've been bed-ridden for up to two full days and general discomfort afterwards. So, I have to find simple solutions like soap and oil, picking off the bugs, I really can't risk exposure to many of the things that people are suggesting. I too have a gas mask like that. I find that even wearing masks with new cartridges in painted rooms I start sensing significant levels after 15 minutes or so, and after that they're no good. Part of the problem is I can't always sense a harmful source till I start experiencing symptoms. Unfortunately, there is only one true method of preventing exposure to harmful chemicals and that is don't go into environments with harmful chemicals. |

Looks like there are some active environmentalist in Alaska with the
same concerns. Here is one page that suggests using castille soap http://www.ipmofalaska.homestead.com/files/soap.html Thanks everyone. wendy7 wrote: Oh my, sorry to hear that you have this problem, I damaged my esophagus a year ago, accidently breathing in exhaust fumes!
