Need brand names of chemicals
Due to neglect (because of both my parents being in extreme poor health- both
of them in their 80's and still living at their home) my poor orchids have the worst scale infestation that I have ever had to deal with. Before chucking what may be salvagable, I need the brand names of chemicals I could try. I will have to buy them at Home Depot or a nursery so I need brand names. My cymbidiums and reed stem epis are all fine, but the rest of my orchids are in need of help. I have ultrafine but wonder if I need to do something else first. Also any tips on using them would be appreciated. I will be repotting of course, but haven't ever had to deal with this bad a problem. Thanks, Diane |

Diane,
Orthene is supposed to be a great systemic insecticide against scale. I know growers who swear by it. I've never used it myself, so I don't have any first hand experience, but here's a name for you to do some research on. -Eric in SF "DVardner" wrote in message ...

Need brand names of chemicals
I have had success with Neem Oil on scale that came in
on new plants. -- -- D. Wain Garrison If you can read you can learn anything, for there are those smarter than you who can write, however, not everyone who can write is smarter than you. "Michael Gerzog" wrote in message om... (DVardner) wrote in message ... Before chucking what may be salvagable, I need the brand names of chemicals I could try. I will have to buy them at Home Depot or a nursery so I need brand names. Orthene is one of a few brand names for a systemic insecticide containing acephate. Just read the labels and look for that. If you can find it, a water soluble powder or granules is better than the liquid, which is a petroleum base. In some parts of the country, acephate is used in "fire ant killer", and is available in places like HD. Otherwise you're most likely to find the emulsifiable (liquid) version. Among other places, Rosemania.com sells the 97% Orthene granules. If you have to keep it inside, the granules have the big advantage of not smelling to high heaven even when sealed up in a container -- the 75% percent powder is horrendous. Unless you have a lot of plants or expect the problem to be ongoing, and as long as you aren't very concerned about toxicity to people or pets, I would go with acephate over Enstar II and the others because of the initial cost and quick kill of the acephate. Also, acephate is systemic and if you're going to continue to be pressed for time, it'll give you a little more leeway in terms of repeat applications than non-systemic products. Whatever product you use, you will have to make repeat applications about 10 days apart. For longer term use, the Enstar II is probably a better bet - it's one of the rare few products that's labelled for use on "interiorscapes." Since it's an insect growth regulator and shouldn't affect mammals, it's certainly safer than most pest control products. Michael |

Orthene WP and Enstar II are fantastic in combination but you're not going
to find them in Home Depot of the likes. You'll be hard pressed to find them in a good nursery. Best bet is online. a Google search will give you some good leads. "DVardner" wrote in message ...

Jim,
Thanks very much for the information. As Larry mentioned earlier, lindane is not very good stuff to have around. It's quite persistent. The Chevron "Isotox" went through many changes of ownership, and was at one time also owned by Monsanto. The Ortho name at least is owned by Scott's, the fertilizer people, but I suspect the juice is still made in the same place. Paul "Jim S" wrote in message y.com... paul i hold in my hand an 'OLD' bottle of ISOTOX made by the chevron corp that contains 56.5% Lindane that is where the confusion comes from as they let the name registration go as of 1982 the ortho comp picked it up and ran with it it was a good name and many people remember it olddays= Lindane newdays= acepate Jim Hope this helps everyone "Paul Simon" wrote in message ... Larry, There seems to be some misconception that Isotox contains lindane. This issue came up about a year ago with someone else and I commented then also. Perhaps there is a product with a similar name. I have a bottle of "Isotox Insect Killer formula IV" by Ortho in front of me. It's a liquid, and contains: 8.0 % Acephate (Orthene) and 0.5 % Vendex (tin containing miticide.) It is liquid, but I suspect the solvent is somthing like NMP,n-methyl pyrrolidone, a rather innocuous water miscible solvent. If one has concerns about health hazards, check the MSDS at the Ortho web site. I keep a small spray bottle with the diluted mix in the greenhouse, and when I see some mealybugs, I just give the plant a few sprays. I'm not aware of any damage to any of my plants. I do avoid spraying flowers so I cannot comment on possible damage there. Paul Simon "Larry Dighera" wrote in message ...

For what its worth, I am down to less than two cents so I just throw in the
little that I have left: A scary and little known fact here is that Brand names and their active ingredient may vary from year to year, from country to county or from state to state. There must be a good reason for this. It probably has something to do with changing manufacturing guidelines and the laws applicable in various jurisdictions where the chemical is sold. Anyway, the various formulations; i.e. liquid, granular, powder, etc may also contain different active ingredients as well as different "inert" ingredients but inert does not mean it won't harm plants, applicators or bystanders under certain situations. If you have identified the insect you want to control as being "scale" then the labels of brand names with active ingredients you find at your local PesticideMart that control scale will list scale among the insects it controls. Nowadays Pesticide makers seem to be using pictures of the insects controlled by the brand name even as the reminds you to read it in its entirety. Brand name X in California might not list scale as an insect it controls but a bottle of brand name X in Virginia will. This might be because they are different active ingredients but, and here's a scary observation: Brand name X in both states might actually contain the same ingredients but one jurisdiction does not approve it's use for scale in over-the-counter residential type home garden applications so scale will not be listed on the bottle that is sold there. Almost certainly, whatever you use will require several timed applications over several weeks. I suggest that you find two different chemicals that control scale and alternate their application as part of a several week long total application cycle. |

OK I am totally lost. I know it is scale, but far more than I can remove by
hand on some plants. Any sugggestions, besides ultrafine that I can spray on? I really only have access to local Home Depot type stores. Hate to throw away some really nice Catts. Diane |

I'd go with Orthenex or Isotox, if you cannot get Orthene WP or Enstar II

Ditto. Your post reminded me that there were some equitants in my collection
that had the hard brown scale that I needed to complete the 3rd round of treatment on. So Thanks! I got out and sprayed with the Orthenex canned spray (Mostly for the oil) However I'll follow up with a 4th treatment (since I let it go 2 weeks too long) of Malathion. I'm probably the only person on earth who doesn't find the smell disagreeable. Luckily I found the soft white scale on a different plant (catt) so I was able to spray that one too.
