Yellow patches on leaves

LenaBeanNZ · November 6, 2008

Hi,
For the past few weeks Ive noticed these yellow patches on just a few of my young plants, about 9 out of 160. The plants are just as healthy and vigorous as the rest, so its doesnt seem to be affecting them. Im very curious as to what it is though, can anyone help?
Thanks,
Lena

To me it does not resemble any well-known tomato disease
(but that could be just the picture, not quite close enough
to the leaf), so my first guess would be bug or caterpillar
damage.

I get this from time to time, I don't worry about it at all. It must be a shortage of some sort of mineral, (or even a slight sunburn). It seems some varieties are more susceptible to it

Thankyou both for your responses. I have had another look, and cant see any evidence of insects. I saw picture online which looked similar, but the unfortunate plant had ben diagnosed with tomato mosiac virus. Im going to keep on hoping for the best. From memory, it was Purple Russian, Yellow Brandywine, Oxheart, San Marzano, and Cherokee Purple that were affected.
