Re: scale on orchids...Scottie!!!

Hi Scottie, was about to reply to Andrea when I saw your message, which is  
way more informative than anything I would have posted.....thanks, I too  
appreciate the info.  I don't have scale on my orchids or bromeliads, never  have 
(knock on wood), but one never knows what the future  holds....
 
Scottie,  I went to the Orchid show/sale at the Reliant  center.  I looked 
everywhere for you.  Saw several people we know, but  I had forgotten your last 
name.  Did you go????  I thought it was  great.  I spent WAY too much money, 
mostly on miniatures to mount.   Took a lot of pictures.  Got to meet some 
really interesting people  too.  Wish we had seen you though.

Andrea,

There is a complex answer to this in the June  Orchids Magazine (formerly AOS
Bulletin), and at the end they quote this  website:
http://nathist.sdstate.edu/orchids/pests/scales.htm which seems to  have all
of the info included in the article.

In addition to the  info in the above link, the Orchids article states:  "The
current  arsenal of effective insecticides for the small grower of orchids is
more  limited.  If you are looking for a systemic, about the only  one
available inexpensively is acephate (=Orthene).  This chemical now  comes in
a wide variety of formulations from commercial wettable powders to  premixed
over-the-counter spray bottles.  If you are using Isotox IV,  this new
formulation is a mixture of acephate and the miticide  fenbutatin-oxide.
Alternatives that are effective include Malathion,  carbaryl, imadichloprid
and the growth regulator kinprene (sold as  EnstarII).  These are highly
effective on crawlers, but not  adults."

In our greenhouse, we use alcohol and a q-tip -- time  consuming, but it
works, or rubbing alcohol mixed with a little Ivory  dishwashing soap and
water in a spray bottle.  So far we've not needed  anything more potent than
that (knock wood).   I know that some  growers highly recommend EnstarII, but
it is VERY expensive.

There  is a book, Orchid Pests and Diseases (www.aos.org or 561-404-2020)
which is  very good.  Most local orchid societies have it in their
libraries --  if you visited a meeting, you could probably at least see if
you wanted to  purchase it.

HTH!
