Blemishes on leaves - can you identify?

luke · June 11, 2011

One of mu plants (Aunt Ginny's) has some spots/blemishes on the leaves.

We have been very hot in the day (100 degrees plus, with 80 degree nights), and my hope is that it might be a result of the heat.

Can any of you I.D. this and tell me the fix?

Thanks

Is it on new leaves/foliage or older foliage? Could be Tomato Spotted Wilt Virus (TSWV).
Check out the sticky post for that to see if it resembles that.

The leaves that are affected are on the upper few laterals of the plant, so it would be the newer leaves.

Not sure it looks exactly like the photos that I've seen in the sticky, so I will look into an in-depth description of TSWV tonight and then decide if the plant gets yanked.

I agree that it does look like TSWV; but I would wait to pull it til I was sure. If the plant is large and healthy and already has a good amount of fruit it still might produce fairly well before it dies. If the plant is immature and it is TSWV then it should be pulled as soon as you are sure.
The very newest growth on the stem that has the symptoms will stop growing and start to shrivel and look funny and soon it will spread to most of the new growth on the plant.

I checked the plant Sunday afternoon and the leaves had gotten considerably worse. Pulled it, and no other plants are showing any signs of it.

Thanks for your comments.
