Bblack streaks on tomatoes

BigVanVader · July 13, 2016

Is this a mold/fungal issue? All my OJ are looking like this.

Thats a new one for me. Haven't a clue.

It could be what's called weather checking,I've seen it before.

I don't know, either.

Is this something that's happening at a certain time, i.e. you noticed it on all the fruits starting on [x] date, or at a certain stage of fruit development, i.e., the fruit develop it when they get to a certain point of maturity?

Is it all the OJ fruit? Do you have more than one OJ plant, and is it on all the fruit on all the OJ plants?

BigVanVader · July 13, 2016

It's all fruits on OJ, 10 plants. Dosent darken until fruits get close to blush. Could be weather checking I guess though those pics look a lot worse than what I am seeing.

Is it visible before it darkens, like a slight color or texture difference or slightly indented? Do you have any pics of what it looks like before it darkens?

BigVanVader · July 13, 2016

Yeah it's visible, slightly sunken. Don't see it on the small fruits but all the medium sized and bigger.

Do you have an stink bugs or leaf footed bugs?

BigVanVader · July 13, 2016

Stinkbugs on my squash, but I have been able to keep the population low from spraying soap/DE mixture. Only seen a couple on my tomatoes, definitely not enough to cause this much damage. No LFB thank god.

I have the same thing on my Zebra Rita. It seems to happen after a big rain.

The line of dots in the center of your picture is making me wonder why it would follow a line like that. Could it be insect damage is one thing I'm thinking. Maybe some sort of worm? I don't know. It is the first time I've seen that on a tomato though.

OJ is Orange Jazz right?

I think that line is just part of some very mild zippering.

zipcode · July 14, 2016

Seems to be some micro cracking in the skin, that starts to rot slightly when the fruit is maturing (it's really on the surface area so it shouldn't affect the overall fruit). Why it happened though, tough to say. I have seen it in rainier periods and especially alternating temperatures, but mostly on the shoulders of the tomato. Some varieties are more susceptible than others.

Almost always when you see a donut like lesion, that is to say lesions with a clear center and brown around it, its bacterial. Copper spray handles bacterial as well as fungal. But use it at the weakest recommended dose.

Yeah Orange Jazz and the dots are just some zippering.
