Auscultation and diagnosis
We can no longer make out the characteristic red of these tomatoes, as the mold has eaten away at the plant. As for the green tomatoes, they do not seem attacked, they appear brown, as if burned, and present blisters. These tomatoes are victims of late blight, a disease caused by a fungus that thrives in a humid and warm environment. The plant can dry out in just a few days. This fungal disease also attacks potatoes and vines.
In the present case, the current harvest is obviously spoiled. It is therefore advisable to tear off the feet and burn them. If the fungus has not yet spread too far, remove the diseased parts to stop the spread. The following year, choose another place to set up your plants. As a preventive, proceed with a fungicide treatment. Choose nettle manure or a copper-based product, such as Bordeaux porridge.
