Another thread about tomatoes got me thinking. Is there a difference
to the types of problems faced by tomatoes with "potato" leaves vs.
those with the more common "cut" leaves?

I'm possitive that they have different enemies and I'm sure that the
back part of my brain knows what they are but I can't recall at this
moment, so I thought that a refresher was inorder.

Thanks for your help!

The older potato leaf varieties probably don't have the disease resistance
that the new hybrids do.

We're smokers. We have a Tumbler in our kitchen window and it's cranking
out 'maters like crazy. It *must* be resistant to tobacco mosaic virus, as
almost all commercial tobacco is infected. (I don't touch the plant without
washing my hands first, but my DH does and the plant is just thriving.)

Thanks for reminding me to was my hands! Sadly, I too smoke. Now I'm
in trouble.

Hogwash!

The fancy shmancy hybrids are the first to succumb to the
biological weapons of The spit!Thrips of Mass Destruction.
It's the pink Branywines that are the most resistant to Tomato
Spotted Wilt virus (the spit! TMD's disease of choice). I tried
a couple of Manalucie plants this year, too, and they're going
strong.

I really wonder sometimes, exactly where do people think
the resistance that is bred into hybrids came from?

Potato leaf plants have a thicker epidermis than regular leaf so theory is
they're more disease resistant/durable. Also, heirlooms have withstood the
test of time, their disappearance in the past was not like the dinosaurs but
because of modern breeding for durable fruits to ship to market.

As for TMV, less than 1% of the current tobacco has the disease.

True...kinda. Alot of the older heirlooms have some resistance to certain
diseases and little or none to others. Disease resistant hybrids were
created taking the desired traits of those heirlooms and combining them.
