Hi there,
I'm from Italy and asked you some questions about pecan cultivation in the last year.
Now, I have a new question for you!
I have some pecan seedlings born about a month ago.
During the first day I noticed some black spots on them and I thought it could be scab (maybe infected nuts) so I treated them once with Tebuconazole and a second time with mancozeb (it is used yet in Italy).
I have a third light treatment and after 2 days some plants started to show black vein spots and day by day leaves started to turn brown and dry.
Last year I had the same problem and my seedlings died one by one but, as I remember,7 I didn't gave any treatment.
Someone told me it could be excess of water.
Last week I put them in a tall homemade pot and I noticed that the bad ones had a spiralized taproot.
According to you what's the problem and what can I do?
I put them for the first month in the shadow and now have them where they receive about 3-4 hours of early morning sun.
I don't know how to expose young pecan seedlings, can you help me about it?
Thank you!
Cheers from Italy!

First pic looks like the start of sunburn more than anything...the other pics less so. Is there a reason why you didn't have them in direct sun to start with? I have a feeling that all of these issues could be avoided by planting direct where you want them. Tap root will go straight down, used to full sun from the beginning, etc...
