Septoria I believe

jmsieglaff · June 30, 2015

I usually prune a leaf off when I notice any spots. Saw this tonight and all the tomatoes got a good spraying. Looks like septoria right?

And the underside.

Septoria it is.

Thanks. I hate it. Get it to some extent every year. I rotate, mulch heavily with straw, remove plant debris In the fall, never water from above, prune aggressively when I see the start of anything, but it just blows in on the rain. It's a little earlier than most years.

This June we've had a lot of rainy days, the total rain has been normal but frequent. Sometimes with good treatment, aggressive pruning and if the weather turns dry in July I can keep it at bay for the remainder of the year.

At least each year I learn what varieties are more resistant (takes longer to develop) and more tolerant (slower spreading and fruit keep setting).

what varieties have you found to be more resistant?the only one I've found to be is sungold.

I couldn't agree more with this statement... except I don't mulch with straw, because it's more work with no benefit to preventing foliage diseases that blow in on the rain....

I've considered spraying, but with the constant afternoon thunderstorms, it would just wash off and not be effective.....
All about the weather......

To echo the others, yep! Septoria. Copper spray manages mine very well, after I cut off and remove infected leaves.

Agreed on Sungold, it is fairly tolerant and spreads slower. I've also found similar things with Black Krim, Golden Monarch, my experiment yellow potato leaf cherry, a dwarf from the dwarf project I'm working on. I haven't grown tons and tons of varieties but those have stuck out as most tolerant in my garden. Ymmv
