My wife would love that plant! She just picked up a pink flowered plant, but those are very nice!

hey guys
I haven't abandoned you. in fact I have lots of random pics to upload (I just keep forgetting to move them to the cloud). today I went to clayton and began bagging some of the early materials, mostly orientals but some other things too.
I think some of you used the delnet bags last year. how did you like them?

Thanks for checking in, now we won't have to send out a search party 
Looking forward to the pics

so I've been sitting on this picture I took of the plumbaginifolia flowers at 5am one morning for a while now. you can see that they are open, but they gradually start to close once its daylight.
I have already harvested, cleaned and filed away the seed from this accession and the quadrivalvis.
Here are a couple of pictures (below) of the Chikamunga Cherokee Sacred Tobacco that im trying to add to the collection. its had a couple leaves removed, but you can see it doesn't produce many at all. for a rustica, the corolla tube is very wide in diameter and you can see all the way down into the flower. it has recessed stigmas and I don't think it would set hardly any seed at all without manual pollination (and even then it still hasn't set very well so far).
and finally, this a peek at the nursery field. its pretty early in the season still and ive already put out a lot of bags.
today I started taking some individual plot photos and some detached leaf pics, mainly of the oriental stuff. today our pathologist also came and toured the field to inspect it for disease. there was a little bit of angular leaf spot (but those are localized infections on lower leaves that can easily be removed) and one plant with tobacco etch virus (the plant was pulled up). I only had three plants this year with tomato spotted wilt virus so far and that's great because a couple years ago it was more like 20.

Nice to hear from you again Jessica !
Looks as if you have a nice grow goin on.
Like your new last name.

It's interesting that you pulled up the plant with Tobacco Etch Virus.
Two years ago, I pulled up the one TEV infected plant. Later in the season, a couple of other plants, remote from the first, developed signs of TEV.
Last summer, the two TEV plants that showed up were left growing in the field, for observation of spread. On the affected plants, TEV ultimately appeared only on a few of the mid-stalk leaves, but spread neither up nor down the stalk any farther. Adjacent plants did not appear to become infected. A third TEV plant appeared late in the season, but again was remote from the earlier TEV plants.
My impression is that insect transmission from other solanaceous weeds in the vicinity was more significant than transmission either from leaf to leaf on the same plant, or tobacco plant to tobacco plant.
I would love any references on TEV spread.

Aphid transmission of TEV: http://www.apsnet.org/publications/...ues/Documents/1983Articles/Phyto73n06_872.PDF
Florida Dept. of Agriculture pub. They mention weekly application of oil for aphid control. They don't mention what the oil is. Any ideas? http://www.freshfromflorida.com/content/download/11303/144109/pp297.pdf

hey knuckle there are lots of documents about TEV in my forum
You have a lot of documents about everything on your forum. A great source of information. You are to be commended for your hard work in assembling all that into one place. Wonderful videos also.

the pathologist said TEV wasn't known to be seed transmissible and plant to plant spread wasn't likely, but we decided to pull it so we could say that diseased materials were removed from the field. its actually the first time I've seen it in the field. it would have been easy to miss tho.
The TEV question has caused me to review some issues I've had during this and previous seasons. Transplants that go into the field late (slow starters and replacements) never seem to get going very well. This year, I had aphid problems within my enclosed porch, which is where I grow my seedlings. I believe the aphids came from one or more of the elderly tobacco plants in tiny pots, that I have been nursing along for a couple of years. (They spent summers outdoors.)
My thought is that these aphids have transmitted TEV to some of the seedling trays, and that this accounts for their sometimes sluggish growth, both in the seedling trays and when subsequently transplanted. So my reservoir of TEV may be my own doing.
With more mature plants in the field that develop some signs of TEV, the productivity seems slightly reduced, but not a real problem.
What I will do:
CONCLUSION: TEV is a real and persistent problem for tiny plants, and will permanently reduce their productivity (and viability). TEV is not a problem for plants that are already growing well in the field.

What I will do:
- Plants in the field that develop TEV late will be left growing, and harvested as usual
- No plants (especially my elderly cohort) that have been outdoors will be allowed back in for the winter. So much for caring for the elderly.
- All "greenhouse" materials (trays, inserts, pots) will either be discarded after one season, or sanitized.
- Any small seedlings indoors that acquire aphids will be immediately discarded.
CONCLUSION: TEV is a real and persistent problem for tiny plants, and will permanently reduce their productivity (and viability). TEV is not a problem for plants that are already growing well in the field.

if you're not seeing visible symptoms in your young plants (like etching, mottling, puckering) then how do you know they have the virus? isn't it possible that the aphid feeding behavior alone could be detrimental to the young plants, especially if they get a colony going?

Have you checked for pythium root rot ?
The root rot and target spot can be caused from dirty used trays . I had outside plants to get root rot this year . They won't grow until planted or treated with terramaster .
Root rot can cause dampening off .

we've been battling pythium root rot in our soil for a while now and have to treat everything with terramaster. we even tried autoclaving the soil (we were already bleaching pots and trays), but that didn't really help. we cant seem to find the source.
All of the seedling suffering appeared to be just from the aphids, but when they were transplanted out, and all aphids removed, they did not thrive in the field. Who knows.
I didn't see any root rot.
More to the issue at hand, I had finished placing all the needed transplants, so the remaining seedlings have been ushered off to the public landfill. (Don't plant your tobacco there!)
The cost of new trays and inserts each year is really modest for me (only 8 each of inserts, 1020s with holes, 1020s without holes), compared to the aggravation of poor starts.
Bob
Pythium is in the pores of the float trays and is hard to soak enough to kill it out . If you use bleach , they need to be rinsed off really good . Bleach will hurt new seedlings . I put my used trays back in my greenhouse where temps get high and kill the Pythium out .They claim steaming cleaning the trays works to . Old plastic can hold pythium .
I use greenshield to wash trays as a second preventative measure .
A lot of people have asked me to sell them some of my used trays and I won't sell them. But I will sell them new ones .
Some farmers are using trays for one or two years and then buying new ones .

this isn't in our float trays, which are always new (and the float beds are always freshly lined each year). its in our small plastic pots that we use in the growthroom.

well it appears the Japanese beetle love affair with the tobacco is over already (not that im complaining). I didn't see a single one today. im happy to report that I think im at least 75% done with bagging already this year, which is great. having help this year has been amazing. ive got a few lines that are lagging, plus a number of mammoth and NF varieties im going to have to wait out the majority of the summer on.
I think its safe to say that both Black mammoth (PI 552439) and Mosaic Resistant (MR) Black Mammoth (PI 551328) are NOT true mammoth (photoperiod sensitive) types, as both were flowering in June (im actually wondering if the "mammoth" was referring to their leaf size). I will let you know more about the other mammoths in the field later.

May want to batten down the hatches.
