Is this virused? Should I pull out?

East Texas, United States(Zone 8a)

looks awful to me. This came from RC last yr, was supposed to be Supreme Garden but not. They sent correct replacement following yr.

I am no expert, but with the red blotches, yellow mosaic pattern and distorted growth it does look like a virus. If it were mine I'd get rid of it immediately.

I'm hoping that other regulars will take a look and comment. But it is looking suspiciously like virus. I found an article but it says password protected so I can't post a link here. ugh.

Also, these bulbs came from RC and I'm wondering if their temporary inability to ship to US had something to do w/ virused bulbs. Well, this is speculative at the moment. I have emailed them but don't expect an answer before Monday.

I will keep you posted on what they say. In the meantime, pls take a look-see and tell me if you've seen anything like this. thanks.

PER RC, THE PLANT IS VIRUSED AND REQUIRES IMMEDIATE REMOVAL

I'm a little disappointed that the regular/experts in this forum didn't at least post a comment, I know I can't possibly be the only person that buys from RC affected by this. Exception being Tom, thanks Tom, you were correct.

RC replied that the virus was acquired by an insect as mine is planted outdoors. Baloney!!!! I had been researching while awaiting for an RC reply or input from you guys, and learned the European Council on plant pathology has found no data about transmission by aphids. Also virus can remain inanctive in the bulb for indeterminate time. these came virused from RC

Here is the article, FYI. Also, if you are concerned, you can google amaryllis mosaic virus and find additional information. Much of the literature does say aphids are transmistters but I firmly believe my bulbs were virused before planting. Otherwise my other hippies would have shown disease and I've been planting these for yrs and yrs.

I have another hippie that shows similar leaf damage and also came from RC. Coincidence? I think not. will post pic later. I will also post leaves in PF so people can see what mosaic virus looks like.

I believe RC is one of the more reputable sellers out there and they replied immediately. They are too serious an organization and I don't doubt plant disease is a high priority item for them. But I do hope this incident will raise awareness of this disease for those of us who buy from everybody and anybody in search of the latest and greatest hybrid. If RC couldn't effectively control it in its stock, how careful/concerned would straight resellers be about this?

That's awful Nery. I have a question, is there anything you can DO to the bulb once it is infected? To get rid of the disease of virus...or just throw it out? I am very unfamiliar with virus in plants. I had a little experience with some Lilies one year, but I didn't realize so many plants could get "sick" like that...seems like I had some Amaryllis once that I was concerned about too, but they did not come out with the leaves affected the same I don't think...I will have to check and see if I can find my pictures....I think I posted questions here about them at the time...will look and see if I can find that post.

anything you can do...

Once it's in then it will remain forever... Only the central growing points (meristems) stay unaffected but that will not help YOU further on this occasion (only a specialist with professional equipment could explant those growing points and eventually regenerate virus-free plants out of these.

Mosaic in Hippeastrums appears widespred to me. A rather high percentage of potted bulbs which I purchased (in Germany) the bulbs being from The Netherlands' source showed to be mosaic-ed. Approximately every 7th potted plant from flowerstores - and I regard this principally as a scandal - but in the meantime I blocked it out of my mind (in order to be capable of sleeping in peace, you know...).
If a reputable company trades virused bulbs then they should be informed, so they can address at their suppliers' source (presumably companies in The Netherlands) and they should insist that distribution of virused bulbs be completely unacceptable.

vossner: I just now saw this thread. I will have to go outside tomorrow and look at all my amaryllis beds. Now I know what virus symptoms look like.

East Texas, United States(Zone 8a)

thanks Haweha and Bsharf. I took some more pics. As I mentioned before, this particular bulb (1 of 3) was sent to me as Supreme Garden. It wasn't. Then there was speculation on a thread that it might be Lovely Garden http://davesgarden.com/community/forums/fp.php?pid=6346731 and I tend to agree but not 100% sure. Bsharf don't be alarmed. the one in your pic look perfectly healthy and my other two also look fine. It's just this one.

I removed the bulb this afternoon and it has the red stuff as well as a couple of soft, black spots. The two things on the sides were bulb offsets.

I wish I could post these in the PF somewhere, I could hardly find pics of virused bulbs/leaves when googling and this are pretty good.

here is a pic of the flower stem. the one on top is the virused plant and the one on bottom is a perfectly healthy stem for comparison. can you see the mottling on the diseased one? the healthy stem is a solid and even green color.

more pic of diseased leaves. This mottling didn't suddenly appear. I simply ignored it, thinking it might be some kind of spring sickness. Then a couple of days ago I was weeding the area and realized this was something more serious.

RC is swearing it's not possible but I can't be convinced otherwise. I have a second cultivar, purchased the following year (2007) with funny looking leaves, also from RC.

Haweha, you are right that they need to know and I am sharing all the pics with them. Somebody named Paul is communicating with me and shows concerned w/o being defensive.

here are the leaves on the 2nd bulb from RC, Night Star. Paul has not confirmed this is virused, but I'm pretty sured it's gonna be.

A lot of people may have been reluctant to reply because they're not sure. I know someone who grows crinums commercially and he showed me how to identify virus symptoms in Amaryllidaceae. Apparently these viruses are very common and they don't always cause major symptoms. Also the severity of symptoms varies between different species/cultivars - some plants can survive indefinitely with few problems, others will survive but have fewer flowers or deformed flowers, and others will go into an irreversible decline and die. When in doubt it's best to get rid of sickly plants so they don't infect others. I think cross-infection via insect vectors is quite possible and does happen, but with mass-produced bulbs the most likely means of transmission is from using the same tools to trim or separate many bulbs from the same crop without sterilizing in between.

Again, I'm not an expert... I just rely on instinct... "that doesn't look right, better toss it".

One more thing... don't panic if you see the occasional red spot or streak - that's just their response to stress/injury. A virus is likely if you also see other signs of distress such as distorted growth in different areas of the plant and/or mosaic pale/dark patterns in the foliage.

Zephyrhills, FL

I pot up all new arrivals, for at least six months,and keep them as far away from the established plants as possible.During that time, I isolate any hippeastrum showing signs, such as that you showed in your photo. I watch to see if new growth continues to exhibit mosaic like patterns , mottling,or other mutation. If it continues to look sick, it goes into the garbage. I keep the sick ones as far away from the healthy ones, as possible. I currently have three Apple Blossom,bought at walmart,in quarantine. The bulbs were obviously stressed. They had begun to get soft,from drying out,and had obviously been tossed around,so it is entirely possible that they will recover,and never again exhibit symptoms.

Potting up in individual (not community) pots & keeping the containers at another location is a good strategy and I practise and I recommend that, too. However, I must admit that I did not handle the another location issue so strictly but until now I had no disadvantage, indoors. Outside the situation can be more critical, since aphids might actually transmit the virus from bulb to bulb.

Gulfport, FL(Zone 9b)

Treat regularly with Cleary's 3336G. Get into a regular habit of treating your bulbs with fungicide. Some bulbs recover quickly, some take longer, a few cash out. You have options. I've received diseased bulbs, peeled them down a bit, soaked in a bath of 50%peroxide to 50% water overnight, allowed to air dry, potted, treated and had healthy bulbs as a result.

Some of this requires a steady hand, a knowledgeable eye and some patience, but it works.
