Bblack streaks on tomatoes - Page 2

Maybe PM the photo to Fred and see whether he has experience with seeing this problem?

I'm sure the fruits will taste fine. It looks to be very much only on the surface.

I had plan to grow OJ next year but this thread make me to re think.

Any changes, BVV? I may grow OJ next year, so interested in how it's doing. Still getting the marks? Do they affect flavor?

Based upon my experience, it is a product of the environment, particularly heat and is more closely linked to stripe genes based upon several years of observation. I am open to a better diagnosis and am not ruling out another explanation all together, but I don't grow many of Brad Gates's slicers/large salad much any more because of this.

I trialed several Boar varieties, and the lighter varieties did it a lot. Pink Boar and blond boar in particular were really bad, but not PBTD. (Vernissage series and Bumblebees don't show it much at all).

I've also seen it on smaller fruit this year in some striped crosses, but then again we have had quite a few days over 100 degrees.

I will follow this thread hoping for some scientific insight. Until then, I treat it like BER, and choose varieties that don't express it on a regular basis.

Yeah, lots of changes. My disease pressure is through the roof right now. Had a hail storm and then rain nearly every day for a week. Grey mold has been spreading despite my spraying, I can't keep up. The new tomatoes on OJ look fine as of now so fingers crossed it was from the weather. It has been a hard year on tomatoes so far and I have had to pull around 10 plants (all OJ still look ok). Time to practice grafting

Same here, Van. I've been thinking about next year already. I could build an automated spray system that ran by itself at 5 am when the sun comes up, because there is no way I'm going to be up at that hour spraying plants.

Yeah I may go to market one more time. I made big strides this year so I feel good about it. Hopefully next year I can grow most tomatoes under plastic.
