Can it be stopped?
What should I do?

May or may not be.
My tomatoes I think have tomatoe blight.
Yo can see all the blotches on the stems an rotted tomatoes.
Were good for a while. I sprayed .
All you can do is cut an burn the leaves.

Do you mean your tomatoes used to look that bad until
you sprayed them and now they have recovered?

What did you spray them with?

No

I been spraying all year till they ripened. I quit

Now thery are almost all shot. You cannot recover them.
Last year was worse.

Once they get like that They are done.

Copper stuff from seed store.

Mix in water.PDR

Yes, we got late blight from some grocery store tomato plants last year.
It spread to the potatoes but I didn't notice how the potato leaves looked because I didn't check for a week or so due to cool rainy weather. When I finally did all the potato vines were down and brown. I pulled the potatoes and as they were curing I started to smell that blight smell. yuk Then the purple started to show up. I ended up with about 1/4 storable, 1/4 had to have bad spots cut out and boiled right away , and the rest on the compost heap. Not cool.

I think that part of the problem was that I rinsed off the potatoes. Now I read that they should not be allowed to get wet. In fact they should not be harvested while the ground is wet either. Had the potaoes remained dry and dirty I may not have lost so many.

The more I look at other sites' late blight photos the less I think that is what I have in the photo above. This years potatoes are about 50 yards from last years. I guess time will tell but I'm going to continue copper like you did with your tomatoes.

This weekend with huricane Earl should be interesting. cool and wet , oh boy.
