Re: [OGD] ALGAE CONTROL
Hi, Cynthia. I grow most of my potted plants in semi-hydroponics using clear-to-translucent pots, and since that is a constantly moist and nutritious environment, algae is a "fact of life". I now use Physan on a regular basis, but used the bleach solution for years with no issue. In either case, I routinely spray the greenhouse walls, floor, benches, plants, and soak the pots. One reason I like Physan better - besides the smell - is that the bleach is a sodium salt (sodium hypochlorite) compound while the Physan is based upon ammonium salt compounds.

[OGD] Revision of CITES regulations effective 9/24/2007
Such changes affect virtually everyone, whether you are involved in import/export, a tourist or a hobby grower. There are sections from 'Personal and household effects' (§ 23.5 and § 23.15) to 'Caviar labeling' (§ 23.71). What if there was a section that better directs us and the agents when dealing with orchids? I'm not a commercial importer. However I'm wondering if there is a provison for public comment or can and should we have input to the process that leads to revisons to the regulations? As we returned from Taiwan this past March, I experienced a rude awakening to the bureaucracy with regard to CITES. I had made every effort to comply providing all of the requisite documentation. My thought at the time was aren't these agents public servants? At any port of entry, shouldn't the agents be equally well versed with the regulations with regards to orchids? There was such an immense difference in how the agents reacted to orchids when compared to my previous experiences at other ports of entry. Rather than protect the orchids, the actions of the agents and others ultimately destroyed the orchids. It did not have to end that way! So I wondered who writes and proposes the regulations? Can an importer/exporter or for that matter any US citizen petition for changes to the regulations? Having encountered difficulties, I'm not content in letting off some steam but essentially leaving the status quo. By not taking action, don't I contribute to the problem? Somehow the intent of the intent of CITES is being trumped by the 'enforcement' of it. What can we (you and I, separately or together) do?

[OGD] AnTec Labs has registered Paphiopedilum vietnamense
Thanks to Terry Glancy for his timely reminder in OGD V9 #302. He is quite correct when he states that AnTec Labs possess a few legally-acquired Vietnamese orchids. Sometime around the turn of the millenium, US Customs confiscated seven specimens of Paphiopedilum vietnamense from a person who was attempting to smuggle them into the country. The plants were sent to a U.S. Botanical Garden, and last I heard they were still there, serving a life sentence at the hospitality of the US Gov. Bob Wellenstein of Antec Laboratories was asked to help propagate these plants, and subsequently offered flasks (both the species and hybrids) on the market. These are plants of illegal origin which have been legitimized by the process they've been through. Terry is sensible to maintain that record of legitimacy by conserving the AnTec clonal numbers and reciepts. There's invariably an exception to the rule.

[OGD] ALGAE CONTROL
Ray B who said: >I grow most of my potted plants in semi-hydroponics using >clear-to-translucent pots, and since that is a constantly moist and >nutritious environment, algae is a "fact of life". I too grow some orchids in semi-hydroponics using diatomite and clear pots, which make it easy to check the water level, but will allow algae to grow all around the exposed side and top surfaces. "Fact of life" is correct. However, since I have set the clear pots inside a slightly larger green flower pot , I have totally eliminated algae from the pot side and only get a few spots of algae on the top surface. Algae is no longer a problem and there is no need to spray. peter . ___ the OrchidGuide Digest (OGD) orchids@orchidguide.com http://orchidguide.com/mailman/listinfo/orchids_orchidguide.com
[OGD] species found (Vietnam)
"species found in Vietnam... in a remote area of central Vietnam... five orchids... new to science and exclusive to tropical forests in the Annamites Mountain Range, known as the Green Corridor, in Thua Thien Hue Province... [photo : http://english.pravda.ru/img/idb/vietnam-5.jpg] Of the five new orchid species, three are completely leafless... they contain no chlorophyll and live on decaying matter. WWF[Worldwide Fund for Nature] is also examining... four orchids, which... appear to be new species. ... The WWF said the Green Corridor's significant population of threatened species is at risk from illegal logging, hunting, unsustainable extraction of natural resources and conflicting development interests, despite commitment for preservation by local authorities. As well as supporting threatened species the Green Corridor... helps preserve water supplies for thousands of people who depend on the region's rivers and contains vital non-timber forest resources for local ethnic groups who earn a significant proportion of their income from the products."

[OGD] Peter's comments
I think Terry misunderstood Peter's comments about the legality of Vietnamese orchids. My understanding is that Peter said that he believed that, according to CITES regulations, any plant that originated directly from Vietnam was illegal. The Antec vietnamense that was sold by them originated in the US, flasked from parents that illegally entered the US and were confiscated. The parent, which came from Vietnam, were illegal. The confiscated plants were offerred to be shipped back to Vietnam. When they declined (or simply did not respond), the paphs were sent to plant rescue centers. I don't know how many, but I believe the NY Botanic Garden was one of them. The Antec plants were produced from seed pods set on the first US grown growths on the parent plants. Therefore, in terms of both CITES and the USFW interpretation of CITES, these vietnamense were fully legal. However, these legal paphs did not originate in Vietnam. I cannot say whether Peter is entirely correct with regard to all Vietnamese orchids, as I have no area of expertise or experience that could confirm or deny Peter's contention. However, other than the Antec vietnamense and helenae which originated from propagated rescued plants, I believe that Peter's statements are probably quite true with regards to paphs. Take care, Eric Muehlbauer in still hot and mosquito (Asian tigers!) infested Queens NYPaphs charlesworthii and appletonianum in bud. ___ the OrchidGuide Digest (OGD) orchids@orchidguide.com http://orchidguide.com/mailman/listinfo/orchids_orchidguide.com
Re: [OGD] algae control
Someone here, I can't remember how long ago, pointed out that copper wire can be used to slow the growth of algae. In the trays of water and rocks I put on my orchid shelves to increase humidity, algae used to grow quite quickly. A small coil of standard copper wire in each glass tray has greatly slowed, and in most cases completely stopped, the growth of algae in my trays. I wouldn't think the ciopper would hurt your orchids-maybe you could place a coil of copper wire on the top of each pot the next time you repot?
