    Smile Bugs

    I was treating the outside non orchids with Di Syston granuals they don't have bugs ( don't want any ) , thought if it worked as well on Orchids as it does on non orchids .. I put some in 3 pots that contained a bark peat perlite mix one plant is an Oncid , one is a Phal . and one is a scrap Catt. piece they don't have bugs but I wanted to see if it would croak them or not . If they did have bugs I wonder if they would absorb enough to kill the bugs? might be able to add some peat to the bark to hold the granuals or ? will let you know if the plants need a moment of silence Gin

    Gin-
    I've used these granules on orchids before...what I did was dumped some in the watering can, stirred it up and then let it sit for a day...I read that the active ingredient releases in contact with water and the granule base stays behind...so I theorized that it would release into the water and the roots would take it up when I watered. I never saw any adverse affects, but I also don't know if the strength was very high either. I also can't say that it worked, as the Oncidium that had aphids I used it on was so bad I decided to cut the spike a few days later anyway? Keep us posted on the experiment.

    I've never tried using Di Syston. That would be cool if it worked--I like Matt's idea of dissolving in water.

    Definitely post back with results!

    Gin and/or Matt, how much do you think we should use if dissolving it in water?? Sounds like a great idea to me, too!

    I really have no idea what the correct amount would be. The instructions on the granules are fairly vague for terrestial mixing into the soil base. I used about 1/2-1 tablespoon's worth in one gallon of water when I did it, and it didn't seem to hurt anything, but again I couldn't say if it was effective since I didn't let the aphids stay around on the blooms long enough to find out! I use this particular systemic insecticide about once or twice a year on my regular houseplants for prevention purposes as I have had an old but I/M re-occuring scale problem. Interestingly, I've never found a scale on any of my orchids, but still get them on my schefflera and spider plants occasionally, so I'm lucky in that regard.

    Thanks, Matt...it's a good starting point. I'd probably have gone waaaay overboard to start with considering how much I hate BUGS! ick!
