Default Sticky substance from palenopsis

I have a couple of palenopsis that are secreting a sticky substance from the
middle of their leaves. It something like tree sap. If left alone,
eventually some scale like insects appear on the edge of the leaves. There
may be no relationship between these insects and the secretion. Unlike other
scale with which I am familiar, these appear wet. When you crush them there
is a lot of moisture involved. Other scales I have seen and treated are dry
and harder. Can anyone give me an idea what is happening. I have sprayed
with an Ortho Oil spray to no avail.

Thanks for any assistance you might be able to provide.

Default Sticky substance from palenopsis

I think there are 2 kinds of scale. The harder outer shell ones, usually
dark brown, and the softer whiter colored ones. (I think these are called
boisduvial scale). I believe the pattern of noticing the sap with
progression to later seeing the adults at the leaf edges or in the leaf
axils is pretty typical for these insects. Treat with any pesticide that
kills scale. I used to use Malathion, but I believe that is slowly being
pulled from the market (at least here in California) I've used plain old
70% isopropyl alcohol and a toothbrush, to kill the adults then wiped any
suspect areas for the next few weeks to be sure the eggs, larvae are gone,
as long as it was only one plant and isolated away from my main collection
(like a phal on the kitchen window insrtead of in the GH.) There are a few
good newer pesticides on the market (made by Bayer here in teh US) that
should kill them off, too. I confess when I look for those I have to stand
in the aisle at the nursery, seemingly for hours, reading the small print
until I find the one I want. Am I the only one or does Bayer's product
names all sound the same to everyone else, too?

The harder outer shell ones, usually dark brown, and the softer whiter
colored ones. (I think these are called boisduvial scale).


There is also cottony cushion scale that's soft and mushy. Starts out
looking like a chip of paint. There may be some sap present. Easy to kill
with alcohol.

Am I the only one or does Bayer's product names all sound the same to
everyone else, too?


Ditto!

Default Sticky substance from palenopsis

This sticky stuff, if left along will eventually cover most of the leaf. I
first noted it because it had dripped onto tile floor. I was walking around
one day in bare feet. I hae not used malathion, but have used the Ortho oil
spray to smother them. The seem to come back. I will try the alcohol. What
has puzzled me is that the sap seems to come from nowhere...from just a tiny
pore in the leave. In any event, it is very slow going.

Default Sticky substance from palenopsis

What I worry about is that some sort of small sucking insect is sucking into
the leaf and allowing the sap to drain out. I usually notice small sappy
droplets or dried sugar sap along the midrib or the edge of the leaf. Sure
enough if I turn the leaf over there'll be a scale on the underside, or in a
few days there'll be a scale at the leaf margin. Sometimes my first
indication of trouble is (like you did) by seeing sappy 'spray' on the
windowsill when I clean up the kitchen. (No comments about my house
cleaning, now! *G*) Then I'll have to treat the plant with something or
other until its gone.

Usually I'm one of those 'better living thru chemistry' kind of people. I
usually like to use some sort of a perticide in order to be sure. I usually
don't like just dabbing away with alcohol, because I believe these are sly,
conniving little critters that, just when you thik they're gone, they come
back, usually with a vengeance and in places that are a real pain in the
neck to get rid of them - like amongst the roots or under the p/bulb
sheathes. Talk about a pain!

But you are right. The sap comes practically from out of nowhere. Then
blammo! A few days later you see the adult and have to treat. Slow going
indeed. My paphs have mealy bug down in the bark, down amongst the dried
old leaves and along the roots and everytime I think I have a handle on them
they come back. Frustrating. I'm about to toss the lot of them.

Default Sticky substance from palenopsis

There is an orchid nursery near where I live and I have been developing a
relationship with them. You know, buy something and talk and talk and talk.
What they suggested, and I showed them the plant, was to take the whole
plant and immerse it in the oil spray I am using. I have not done that
because of the quantity I would have to mix up, but I may still. In your
case, wehre the insects are hard to get at, perhaps this is a solution,
particularly if you do not want to loose the plant.

Mix one teaspoon each of cooking oil and liquid soap in a quart of water,
and spray the entire plant. The soap both emulsifies the oil and breaks
down the waxy coating on some insects, while the oil smothers them.

I recommend against immersing roots in oils, as the velamen can trap the oil
too well, potentially suffocating them.

I had thought about that too. I have not dipped the whole plant as yet, but
if I do, I will figure out how to hold it upside down so that the roots do
not get immersed.

I have been also thinking about a systemic pesticide as thse critters seem
to be coming from the inside out. I do not know what the effect would be on
the roots, however.

If it's a systemic like acephate (Orthene) or imidicloprid (Merit), it will
be absorbed with no damage to the plant.

from the middle of their leaves. It something like tree sap. If
left alone, eventually some scale like insects appear on the edge of
the leaves. There may be no relationship between these insects and
the secretion. Unlike other scale with which I am familiar, these
appear wet. When you crush them there is a lot of moisture involved.
Other scales I have seen and treated are dry and harder. Can anyone
give me an idea what is happening. I have sprayed with an Ortho Oil
spray to no avail.

Thanks for any assistance you might be able to provide.

Default Sticky substance from palenopsis

I spent some time today looking through the Internet for purchasing sources
for these chemicals and visited my local nursery. Is there an online place
to purchase either of these chemicals at a reasonable cost. That is of
course relative, but the quantities that my nursery has will last a life
time and then some. I only have a small number of plants that are problems,
about 15, and just want to try these things out. Unfortunately, I suppose,
I get attached to my plants, particularly when I have had them for awhile.

If it's a systemic like acephate (Orthene) or imidicloprid (Merit), it
will be absorbed with no damage to the plant.

I had thought about that too. I have not dipped the whole plant as yet,
but if I do, I will figure out how to hold it upside down so that the
roots do not get immersed.

I have been also thinking about a systemic pesticide as thse critters
seem to be coming from the inside out. I do not know what the effect
would be on the roots, however.

Mix one teaspoon each of cooking oil and liquid soap in a quart of
water, and spray the entire plant. The soap both emulsifies the oil and
breaks down the waxy coating on some insects, while the oil smothers
them.

I recommend against immersing roots in oils, as the velamen can trap the
oil too well, potentially suffocating them.

There is an orchid nursery near where I live and I have been developing
a relationship with them. You know, buy something and talk and talk and
talk. What they suggested, and I showed them the plant, was to take the
whole plant and immerse it in the oil spray I am using. I have not
done that because of the quantity I would have to mix up, but I may
still. In your case, wehre the insects are hard to get at, perhaps this
is a solution, particularly if you do not want to loose the plant.

What I worry about is that some sort of small sucking insect is
sucking into the leaf and allowing the sap to drain out. I usually
notice small sappy droplets or dried sugar sap along the midrib or the
edge of the leaf. Sure enough if I turn the leaf over there'll be a
scale on the underside, or in a few days there'll be a scale at the
leaf margin. Sometimes my first indication of trouble is (like you
did) by seeing sappy 'spray' on the windowsill when I clean up the
kitchen. (No comments about my house cleaning, now! *G*) Then I'll
have to treat the plant with something or other until its gone.

Usually I'm one of those 'better living thru chemistry' kind of
people. I usually like to use some sort of a perticide in order to be
sure. I usually don't like just dabbing away with alcohol, because I
believe these are sly, conniving little critters that, just when you
thik they're gone, they come back, usually with a vengeance and in
places that are a real pain in the neck to get rid of them - like
amongst the roots or under the p/bulb sheathes. Talk about a pain!

But you are right. The sap comes practically from out of nowhere.
Then blammo! A few days later you see the adult and have to treat.
Slow going indeed. My paphs have mealy bug down in the bark, down
amongst the dried old leaves and along the roots and everytime I think
I have a handle on them they come back. Frustrating. I'm about to
toss the lot of them.

This sticky stuff, if left along will eventually cover most of the

walking around one day in bare feet. I hae not used malathion, but

I will try the alcohol. What has puzzled me is that the sap seems to
come from nowhere...from just a tiny pore in the leave. In any event,
it is very slow going.

I think there are 2 kinds of scale. The harder outer shell ones,
usually dark brown, and the softer whiter colored ones. (I think
these are called boisduvial scale). I believe the pattern of
noticing the sap with progression to later seeing the adults at the
leaf edges or in the leaf axils is pretty typical for these insects.
Treat with any pesticide that kills scale. I used to use Malathion,
but I believe that is slowly being pulled from the market (at least
here in California) I've used plain old 70% isopropyl alcohol and a
toothbrush, to kill the adults then wiped any suspect areas for the
next few weeks to be sure the eggs, larvae are gone, as long as it
was only one plant and isolated away from my main collection (like a
phal on the kitchen window insrtead of in the GH.) There are a few
good newer pesticides on the market (made by Bayer here in teh US)
that should kill them off, too. I confess when I look for those I
have to stand in the aisle at the nursery, seemingly for hours,
reading the small print until I find the one I want. Am I the only
one or does Bayer's product names all sound the same to everyone
else, too?

Go to your local Home Depot or Lowes and read the label on the "Bayer
Advanced" formulas, as they contain Merit.

I use the "12 Month Tree & Shrub Insect Control" at one ounce per gallon. I
prefer it to some of the other formulas, as they have other ingredients I
don't want.

Thanks. The nursery close to me has "12 Month Tree & Shrub Insect Control"
and I did not buy it because it was a huge bottle ($30) representing several
life time supplies. I can just add what is left over to my will.
