HI all
Want to do some breeding with some older rare Laelia anceps varieties, but
feel one of them is virused
Does any one have an opinion on the transmission of virus through pollen?

That is a common way of transmitting bacterial infection, not viruses.

Giles, your the second one to mention this to me. I was discussing viral
problems with James Rose, and that is exactly what he was concerned about.
Next time I am at Cal Orchids, I'll ask if he has come up with a treatment for
the benches. Personally, I don't have this problem as I grow on
Hi Roger. Critter Creek Labs tests for CMV and ORSV independently, their
double well test actually being a 4 well test, 2 each, so they can report the
incidence of each in the sample. Yes, it is pricy, and they raised their
prices last year, after my last testing. There is a price break at
The recent discussion about virus infection raises an issue I have long
wondered about. If I find some infected plants in my greenhouse I can move
those plants out of the greenhouse, but isn't there some danger of the bench
surfaces retaining some latent virus that could then infect new
There is a process, maybe used in Australia too, that cures grape vine cuttings
of virus by immersing in hot water for a number of minutes. I tried this
process on some of the first plants to come back with a positive test. All
leaves were lost, and most plants did not recover, but I am
Hi Cynthia--
Does the testing service actually identify the particular bacteria or or
virus? I suppose that could get pretty costly but it sure would be
interested to see something more focused on actually specific bugs.

Hi Oliver. All testing so far has been with Critter Creek Labs.
Interesting. Of course, knowing that the plant is infected does not take one
much further forward, unless you throw it out. I recall some Australian

I have been monitoring the thread on Virus but have not had time to
contribute. In 1986, I bought the remains of the Shaffer Phalaenopsis
stud bench. At that time people were becoming increasingly aware of
virus in older collections. I wanted to test all of the breeding stock
so I would

A warning: I browsed (26 Jan 06) the Simanis Orchids (Indonesia) site - for
which I am *not* going to give a URL - and it immediately tried to download a
trojan virus onto my computer. Fortunately I have heavy duty protection and it
did not get anywhere, but others may be less protected.
Did you notify them that this had happened. I have found that lots of
sites in some areas of the world are subject to lots of hacking and
can have Trojans or other programs installed by them without the
owners knowledge. I have even seen it happen to severs at various
institutions in the U.S.
