Help with tomato plants and disease
Its getting worse day by day. I discovered the disease two days ago and removed all the affected branches from the tomato plants. I repeated yesterday and today. But today I found out that one of the plants had the same darkening on the main stem and I'm worried. I fear its mold/fungus, because it's been exceptionally rainy, humid and colder for the last two weeks (above average). It's the middle of the summer and we should have high temperatures - 30 degrees C (86 degrees F) and higher and lots of sunny days with an occasional short thunderstorm. For the last two weeks it's been from 20-25 degrees C (68-77 degrees F) and lots of rain.
And here are the pictures:
My question is. Is there any way I can save the plants and how? Any chance to save the plant with the main stem infected? It has some nice tomatoes on and I would be bummed out if I had to discard them?
