This came up on Alpines list and I recieved permission from Dick to post it here. Be sure to follow the links provided for more information. It sounds like Oregon is on top of SOD problems, I have no idea what Washington is doing (if anything).
I was surprised at the native plants on the list that can be hosts to SOD.
Sudden Oak Death (SOD), Phytophthora ramorum
Oregon has been aware of the coming Federal quarantines for some time and has taken actions to get ahead of the curve on this problem. In June the Oregon Association of Nurseries (OAN) ask the Oregon Department (ODA) to institute an emergency quarantine of host plants from California and an inspection, testing and certification program for all Oregon nurseries. The relevant news releases can be found at OAN. In mid 2004, Oregon instituted a quarantine on all host plant material coming into the State. The Oregon quarantine can be found at ODA and in general is as follows: ODA's emergency regulation prohibits California nurseries from shipping these regulated plant species into Oregon, unless the nurseries and individual shipments of plants comply with specific requirements:
a.. The nursery has undergone an annual inspection for the presence of P. ramorum (to include testing of host and associated host plants);
b.. Each shipment of host and associated host plants destined for Oregon must be inspected prior to shipment (if symptomatic plants are found, then samples must be collected and tested and found free of P. ramorum);
c.. Shipments of nursery stock must have an official certificate verifying the plants meet quarantine requirements, and;
d.. Receivers in Oregon of the regulated plants musty notify the ODA of the arrival of shipment.
These rules since been modified and updated to include host material from all other locations. The OAN has been most upset at the slow reaction of the USDA in response to this problem and is pleased to see that it has finally taken action.
Oregon takes this problem very seriously and the Industry and the State have worked closely to get an inspection and certification program up and running. Over 1000 nurseries have been inspected and certified to ship host material. A list of these nurseries can be found on the OAN web site. A list of host plants can be found at the USDA web site.
I know of 3 instances of SOD in Oregon. A forest tract in Curry County in Southwest Oregon. Some 50 acres was burned. A container nursery East of Portland on material from Europe. All stock was burned. A large wholesale grower in Forest Grove with productions facilities in California. All stock was burned. This is where the Connecticut stock came from. To my knowledge there have been no reports of SOD other than these three and none on any plants that originated entirely in Oregon.
I really do feel that people can have confidence in Oregon grown plants and that both the State and the industry are on top of the situation. I do not ship any host material but my nursery has been inspected and certified. I am no longer a member of the Oregon Association of Nurseries but I whole heartedly support their actions on this matter.

Glad you pasted that link for Oak Death Free nurseries.
A Dept. of Ag person called me yesterday because Tuefel had me in their records from last spring as a purchaser of Viburnum davidii.
Teufel found a few bad ones and the Dept. of Ag was trying trace down the stock.
They mainly wanted to know if I still had them myself.
So there is a fairly thorough network about this.

Unfortunately, it sounds like some bad stock is still getting through even with all the controls. I hate to even think what is going on here in Washington state as we seem to not be as on top of things as you are down there. But then your state has so much at stake with the agribiz down there.
I hope this doesn't become a major problem.

Thanks for the links, Debbie. It's amazing how many different plants are affected and what the symptoms are. Very good to know!

You are welcome. I moved this back to the general gardening area. At first I thought this was for native plants, but I am realizing this is about all types of plants.

I spoke with the ODA on 1/5/04 in a nutshell here's what I learned;
The USDA SODS quarantine is in effect on 1/10/04.
As of Monday SODS host plants cannot be shipped out of state unless the plants and Nursery are certified SODS free.
Non host plants will have a 60 day grace period. After that date (3/11/04) then all plant material must be SODS free.
Seeds are exempt...so far...
I am awaiting my inspection...........

sod certification is quite easy. i am quite proud of the dept of ag for being all of this problem. I have a very small nursery and my inspector knew i went to washington with my plants and was here, had me inspected, and ready to be at market opening day!

Welcome to Rainy Side Basilgirl! Can you tell us what you went through during the inspection?

When the inspector came here to check my site he looked at the salvia plants that had leaves. He decided they were OK . I had him take samples of host plants on the property. He took a leaf from Viburnum tinus, Kalmia, Pieris and a Camelia. It took over 5 weeks before I had an answer. The reason it took so long was becuase they found another Phytophtohora on the Kalmia which meant they had to retest the sample.
I am happy to say my site is SOD free and I can ship non host plants out of state. .
You can find the list of SOD free nurseries, host and non host nurseries, at the ODA website.

about the same, he came by took samples off host plants and gave me a shipper #. Got my paperwork to get a 'shield' within 2 weeks. i was impressed with the speed.
As long as you make sure the plants you buy are from an inspected nursery, all will be well.

I don't know all the details but officials came to our nursery in WA and made us put some camellias in quarantine because they had come from a nursery in CA had was found to have some problems. They tested them and they were ok and we were able to put them out back for sale within a week. This was back when they were just starting to get the rules in place but even so I thought they were pretty quick about it. The only bad thing is I know it will be harder to get certain plants, like Arbutus unedo, because they are mostly grown in CA and are host plants.

I know I was reluctant to buy the Arbutus last fall, but really wanted to replace the one I had to move and subsequently killed it.
Thanks Salvia, Basil and Fern for answering how they are inspecting and keeping our gardens free from this awful disease. Lol writing your names I feel like I am in a botanical garden.

Since I don't ship or sell host plants I found that I do not need that shield.
It is recommended that I include a copy of the SOD FREE Non Host Nurseries webpage, which includes my mursery, from the ODA website.
If I ever wanted to ship host plants or God gorbid salvias become host or associated host plants then I would need that Federal Shield on my shipments.

glad to hear all are feeling good about the ag business in the area. Canada and Europe is even starting to lift quarintine restictions.
Koodos to everyone , just remember when buying, ask, are you certified?
