I have noticed that when this has happened to me that fruit production just about stops and it's really not worth trying to proceed. Since these diseases are both soil and wind-born all you can do is to pull up the plants, burn them and not plant that type of vegetable in that area for 2 or 3 years. One can slow down the disease if one starts a prophylactic regimen before or as soon as the disease shows up. I used to have alternaria bad every year but by using cornmeal at planting and before the disease starts my instance of it has dropped to almost zero. I still get it late in the growing season but in my climate it is so hot that nothing grows anyway and I have stopped the use of cornmeal. Possibly if I kept on putting it out I could stop it for good.Yep I would agree..and no good fast cure path. It is really tough to stay ahead of once it takes over a large portion of the plant and gets inside the plant.
Here are a few pics of the fruit. They don’t look bumpy or depressed yet, but skin doesn’t look right on the bigger fruits. Lots of flower drop too.IMO I think what you have going on is a fungal infection, either alternaria or septoria. Are any of the fruits affected and if so how? A picture would be great. Look for bumps or depressions on the fruit.
What I was looking for were signs of anthracnose which has similar symptoms of alternaria and septoria. I see none. In the future when you water try to keep the leaves dry and use mulch to keep soil from splashing up on the leaves.Here are a few pics of the fruit.

Pics from this morning. So best solution is to pull the plant this year and make sure to do a prophylactic soil regimen next season?The glare from the setting sun plays unfortunate tricks. Any chance of an early am shot or 2?
Since the disease is already there in the soil go ahead an let the fruit ripen, then pull up the plant and rake up ALL debris and burn them. As soon as you've done this I would start applying horticultural cornmeal to the top of the soil. Then when planting time comes again keep a dusting of cornmeal on the soil and plants. If you start to see a whitish growth on the cornmeal that is what you want to see. It's called tricoderma, a beneficial fungi that eats alternia and septoria fungus.Pics from this morning.
