[OGD] RE: Orchids and Antibiotics
I have used antibiotics labeled for agricultural crops successfully on Phalaenopis for bacterial leaf spot. They should only be used as a last resort. Using antibiotics labeled for fish would be a formula for disaster. Crown rot is normally caused by fungi, against which antibiotics are ineffective. I would respectfully suggest that improved culture, particularly improved air movement, temperature management, and irrigation scheduling should reduce problems. If these persist or cultural conditions cannot be changed, use a fungicide and be sure to use the correct protective gear when applying it.

[OGD] help needed - description of Cattleya quadricolor Bateman
Hello OGDers : After obtaining from various sources descriptions of the species known today as Cattleya quadricolor, I have been unable, so far, to get a copy of the description published by Bateman : The Garderners' Chronicle, 1864, page 269. Could you help with a photocopy or a scan of that description ? I am preparing an article on the taxonomy of that species. Thanks in advance for your help.

[OGD] RE: benches
Judy wrote: I'm trying to locate a source for heavy duty black plastic plant benches like Home Depot, Lowe's, etc. use in their nursery departments. Can anyone on this list point me in the right direction or recommend a source for plant stands or benches that are attractive enough to use on a screened porch for a large collection of catts and phals? Hi Judy, I use grid panels that I obtain from stores that salvage and resell retail display equipment. The grid panels are available in a variety of sizes and come epoxy coated in basic colors, usually either black or white. Attached to a simple pipe frame made to the desired height, (which can be painted) they are rust and rot proof. They offer plenty of ventilation and snails seem less inclined to climb on them than any other type of bench I've tried.

Re: [OGD] bush snails and Mesurol
Hello Everyone, I found some Mesurol for slugs (and snails, I assume) in the local garden centers. On the label it says poison... so I assume it should be VERY strong. Unfortunately, I found this in a German shop, and the instruction manual is in German... and I understand extremely little of what is written there. So: can anyone provide me with dosing info and what precautions I should take? Are they suitable for use indoors?

[OGD] Antibiotic phytotoxicity
Steve Topletz [EMAIL PROTECTED] spaketh thusly: Antibiotics are to my knowledge extremely phytotoxic, more toxic to the plant than to the organism. Most are, yes. We routinely use kanamycin for transgenic selection (neomycin phosphotransferase expression using nptII). We also use bialaphos (a tripeptide antibiotic that is also a pretty darned good herbicide) with resistance conferred from the Bah protein in Streptomyces hygroscopicus; hygromycin phosphotransferase (hpt); gentamycin acetyltransferase (accC3); bleomycin resistance; and blah blah blah. The trick is that since plants normally die in the presence of the antibiotic, if we install a gene of interest, and it is linked to antibiotic resistance, then only successfully transformed plants will survive in the presence of the antibiotic. Look for the first generation of transgenic phals to hit the shelf to be resistant to kan or whatever. In fact, I wouldn't consider it unlikely that orchid judging someday may require some form of leaf testing for the presence of selectable markers. Remember, you read it here first. (That'll work until the marker genes can be removed, or something like the mannose-6-phosphate system come online, making antibiotic selection less useful.) However, there are two that stand out in that they are not sufficiently phytotoxic that they may be employed to rid cultures of the agrobacterium that are used for transformation: carbenicillin, and Timentin (ticarcillin + clavulanic acid). The former runs $15 a gram from PhytoTech, the second runs about $22 a gram. We routinely use several hundred mg/L of carb or tim in media with no untoward effects versus a control. OTOH, 1-2 mg/L of bialaphos kills just about everything, and 4+ mg/L is invariably lethal unless transformation has been successful. Whether either would actually do any good in mature plants, I don't know. Tissue penetration may not be sufficient.

Re: [OGD] Bush Snails, Caffeine and a Bit of Rambling History
Martin writes: Those pesky critters! I used to have them, and slugs as well, but now they seem to have disappeared and I really don't know why. snip When this thread was re-opened I decided to scout again. No slugs or bush snails on 40 potato slices!!! I still have a bottle of unused caffeine solution. It's a matter of _intent,_ Martin! ;-) Once your local gang of molluscs find out you've really got the means to nuke them to the last degree, in the depths of the night they confer and concur, (without your knowledge or permission) OK, we'll go. We mentally threaten to really throw out that 'valuable' plant which hasn't flowered for the last decade, and lo and behold, it sprouts a host of buds... And when, thru personal growth or true serendipity we at last acquire the emotional skills to deal harmoniously with a certain class of nasty person, they disappear forever from our lives!
