Insecticide / Miticide for Brugmansia
Having found no newsgroups for ornamental plants, agriculture chemicals, or
house plants, I hope someone here can provide some advice. I have a few houseplants (Brugmansia hybrids) under attack from spider mites. The best treatment I have found for spider mites is a miticide called Avid. However, Avid is only sold in large quantities for large amounts of money ($300 US per container). But I note from reading the Lable and MSDS online (something more people should do) that the active ingredient in Avid is abamectin. When searching for abamectin on the internet, I find that it is chemically very similar to ivermectin, differing only by a double bond vs single bond in one location. For a chemical diagram see http://www.alanwood.net/pesticides/abamectin.html and http://www.alanwood.net/pesticides/ivermectin.html Now ivermectin is readily available in smaller quantities from the local veterinarian where it is used to control internal and external parasites in livestock. I use it for pets too, a practice that is very effective against flea outbreaks, but off lable. So I plan on aquiring 1.5 ml of Ivomec injectible from my vet, adding an emusifier (likely a ml or 2 of the premium ag chemical surfactant blend Merge by BASF) and bringing the volume up to 1 litre with RO water. This mixture will have an active ingredient level between the lable rates given for Avid. I can then pour into hand sprayer and apply in accordance with the Avid lable. Any comments in regards to my idea would be greatly appreciated. -Joe |

Or, you can do as I do, someone who collects brugmansia, grows for sale to the
trade, brugmansia, and is always in a stage of propagation of brugmansia, and use insectidical soap as directed.

Insecticide / Miticide for Brugmansia
That is most interesting. Could you please tell me what product you use,
what is in it and how it is applied. I have tried a commercial insecticidial soap with the last outbreak of spider mites that I had. The product I used promptly yellowed all of the leaves and caused a great deal of leaf drop. It was also not particularly effective. My insecticidal soap is 2% potassium salts of fatty acids sold under the brand "Safers" Natural. After that last outbreak and the problems that I had with the soap, I promptly brought out the nasty chemicals, in this case dimethoate (Cygon or Lygon). Cygon is slightly phytotoxic at levels high enough to kill spider mites, but at least it works well. I am seeking a less phytotoxic solution. Perhaps I did something wrong when using the soap or I should try another brand. -Joe "escapee" wrote in message ...

Insecticide / Miticide for Brugmansia
Update:
Fortunalty the ivermectin is in a solution that facilitates its dispersion in water. Ivermectin by itself is a non polar compound and does not disperse or dissolve in water. Merge cannot be used as a surfactant / solvent mix because it causes the Ivomec injectible fluid to coagulate. Perhaps it contains an incompatible adjuvunct or preservative agent. As of yet the spray does not appear to be phytotoxic. I have sprayed a few leaves with no measured ill effect on the plant yet. In a few more days, I will try to spray the whole plant to test the effectiveness of the chemical against the spider mites. -Joe "Widdups" wrote in message ...

Insecticide / Miticide for Brugmansia
Interesting, if it works, and doesn't kill the brugs.
Avid is also sold in 8 oz containers for $99, if you look up Avid and 8 ounce. It's used 4 drops to a 32 oz sprayer (average spray window cleaner bottle) and will last a very long time. I went ahead and bought it, since mites all but destroyed my dozens of roses before they attempted the greenhouse coup. It was to late for the roses, but it cleared them out of the GH without damage to the brug babies, and I'll soon mix up a gallon batch for all the outdoor roses. Good luck with the ivermectin experiment, and please let us know what comes of it. "Widdups" wrote in message ...

Yet a further update...
The ivermectin spray solution does not appear to by phytotoxic as I have sprayed it on my brug and the other plants that were in contact with it including a phylodendron and umbrella plant. Sorry I do not know the latin for those or even if I spelled them right. Anyway, the mites appear to be no more and my brug which had lost many leaves to mite damage and Cygon spraying (before I thought to use ivomectin) is leafing out again. A very effective solution to my mite problems for $3. If you try this at home remember to spray a few leaves first to test phytotoxicity, and of course insecticides are poisonous so take some basic precautions. This spray is less poisonous that some organic sprays out there and less than most conventional insecticides without the nasty smell, so I think it will become a important part of my IPM (Integrated Pest Management) program.

Hello Joe,
I'm interested in using Ivermectin in my garden. You said you did not need anything to make it water soluble?, You just mixed 1.5mL of Ivermectin with a liter of RO water?. Is the Ivermectin you used 2%? Thanks |
