Striptease infected afterall!

Post by Liselotte »

10 Striptease received in spring of 2004 and planted in a pot showed signs of HVX. I had just read on the forum about Striptease from Holland and possible infections.

Paranoia struck :bd: :bd: :bd:

Thanks to Chris and all the information on the forum I was able to deal with it. Leaves of Striptease and 3 other Hostas were sent to Dr. Lockhart. the leaves were sent in October and only secondary leaves (looking o.k.) were still alive.
No traces of HVX were found.
The following year all plants leaved out perfectly. Just for safety, the plants were kept in isolation for another season.
In 2006 they looked o.k. in spring and were planted out away from other Hostas. A late frost damaged most Hostas.
New leaves looked normal. 2007 another late frost, again the new flush of leaves looked fine.
3 weeks ago I noticed changes, 10 days later the unmistakable signs of HVX.
All 10 plants went into the trash immediately. Because of my ignorance before, it would have been possible to spread the disease with a tool. since the scare in 2004 I have been constantly looking for signs of HVX. sofar so good.

It took three years to come to this!

What a shame, but thank goodness you learned about HVX a long time ago and knew how to prevent it's spread while working in your garden!

So sorry about your Striptease.

I am curious what Chris will say about them...reason is that it looks like the green is between the veins, rather than on the veins. Sometimes the center of Striptease, Hanky Panky and others from that line will change colors in the center and look a little striped or spotted.

Have you had them tested for HVX since the dark spots showed up?

Charla,

No, I did not have the plants tested again. Here in Switzerland, they can't be tested. By the time I can visit the US the leaves would be gone anyway. the sad part is, most people don't know about the virus. I have been preaching about HVX ever since I found out about the threat 3 years ago, but think nurseries don't know and don't want to know about HVX. I am the bad guy to even talk about it.

Lisolette, I certainly understand about the lack of growers and distributors taking HVX seriously. Same problem here.

I still hope Chris can check in and take a look at your pictures....

Hi,

That definitely looks like HVX. The symptoms start along the veins and then eventually can fill in between.

Back in 2004 I believe Dr. Lockhart was just perfecting the ELISA test (and probably continues to perfect it), so it was certainly possible to get a false positive, especially if the concentration of virus was too low to detect. That was the year he was testing for free so I don't think he had the time to invest in double checking every sample.

The virus can take some time to really show, and since plants try to fight off the virus the symptoms can sometimes be suppressed.

Sorry that it took this long to find out :(

Thank you Chris!

Now I do wish I had followed my instincts and destroyed the Hostas when I fist suspected the Virus. That first year I was so paranoid and suspected every blemish on a Hosta to be the virus. We hardly ever get away without late frosts in spring. There are varying degrees of damage and looking at hundreds of Hostas daily, I think to have a good eye for frost damage. When the new leaves look perfect, there seemed to be no reason to worry. The leaves sent to Dr. Lockhart were second growth because by late fall, the old leaves had shriveled. That was probably my mistake. The new leaves showed no signs of virus. However, these plants looked fine until July of this year and when I first saw some odd spots, it took just days to get worse.....
Although, the plants were growing away from other Hostas,
paranoia is back....

:o geesh, so sorry to hear about the problem, but it's nice to be able to read about others problems and how they deal with it! Thanks for sharing it, even if it is bad news, it's news we need to be reminded about! :(

Strip Tease and HVX

Post by DryGulch »

It seems to me that Strip Tease was sort of a beachhead hosta for the initial warning that there was HVX out there in the year it was the Hosta of the Year. It seemed like every Strip Tease I saw that year was infected. Then the flags went up on Golden Tiara, Sum & Substance, Gold Standard, etc.

Are there any Strip Tease out there which were retailed in 2004 or 2005 that could have actually been HVX-free?

I'll note I have never attempted to add this one to my collection, yet is is a pretty hosta. I recently saw one in a horticulture tech school's bed, obviously infected.

Just sort of curious. Anyone's personal notes?

I added a single bare root Striptease in 2005 and is therefor in it's 3rd growing season in my yard. Not even a HINT of HVX or anything to be concerned about. It's been a great grower, going from a single eye in '05 to 5 in '06 and this year there are 14 eyes. I purchased it at a local nursery off a rack of those blue background labeled bare root perennials you see every spring, a good deal of which originate in Holland.

I have the plant in a large container and scrutinize it at least once a month and will continue to do so next year as well, but, touch wood and whistle, so far so good!

Hmmm...

Post by DryGulch »

I saw one such plant that looked to have about 14 eyes as well this summer. Beautiful specimen and just huge, as were all the hosta in this specific gardener's yard. No signs of any virus on any hosta that I saw. It sounded like she purchased it in 2005, so I am naturally suspicious. Every Striptease I have ever seen in this area in retail situations has been infected (as well as the majority of hosta offered for sale)...not to say she didn't purchase it elsewhere.
