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. Clinton Terry |

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? K Barrett "W. Clinton Terry" wrote in message .. .

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! Diana |

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.

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. K Barrett "W. Clinton Terry" wrote in message .. . This sticky stuff, if left along will eventually cover most of the leaf.

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. "K Barrett" wrote in message ...

Sticky substance from palenopsis
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. -- Ray Barkalow - First Rays Orchids - www.firstrays.com Plants, Supplies.

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.

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. Clinton "Ray B" wrote in message news:WRLmh.1888$SQ1.301@trnddc03...

Sticky substance from palenopsis
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. -- Ray Barkalow - First Rays Orchids - www.firstrays.com Plants, Supplies.

Sticky substance from palenopsis
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.
