[IBC] Sudden oak death and you
As you know, the "sudden oak death" pathogen got shipped around the
country this spring on Monrovia nursery plants. If you've bought a plant that has a Monrovia tag on it, especially a camellia, you might want to take that plant to a Cooperative extension office, on the off-chance that they've instigated a whole-state search for it. If you've already planted the plant, just call them and tell them. The state Ag departments can trace the plants all the way to retail nurseries, but often nurseries don't keep records of who they sold each plant to, and the trail goes cold. Other than that, be calm. Go to http://www.suddenoakdeath.org/ if you have questions, and certainly check out the list of hosts, and the pictures of symptoms. Unless you have a tanoak or a live oak bonsai, your trees are not in any danger from this pathogen, which doesn't do a lot of damage on most of its hosts. The problem is that it might spread off an infected plant into the ecosystem, and there's no way to know (at this point) what that would mean. In Australia, Phytophthora cinnamomi got loose and has significantly altered the forest structure on that continent (any Aussies want to comment?). The government is trying to regulate the spread of the pathogen through "official" channels, doing inspections of nurseries, etc. The only concern I have is that bonsai travel through very unofficial channels; friends trade bonsai, sell them at shows, etc. Be careful: don't move host plants out of California, don't buy host plants from California. If you have questions, but don't want to incriminate yourself, you can ask me and I will tactfully get an answer for you. Nina, your friend in the government, unless that's an oxymoron. ************************************************** ****************************** ++++Sponsored, in part, by John Quinn++++ ************************************************** ****************************** -- The IBC HOME PAGE & FAQ: http://www.internetbonsaiclub.org/ -- +++++ Questions?
