Potato or tomato plants that are infected may rot within two weeks.

    Alternaria solani is a fungal pathogen that produces a disease in tomato and potato plants called early blight. The pathogen produces distinctive "bullseye" patterned leaf spots and can also cause stem lesions and fruit rot on tomato and tuber blight on potato. Despite the name "early," foliar symptoms usually occur on older leaves.   The third warning is that weather conditions conducive to the spread of potato blight will develop on Tuesday evening and night and continue through the rest of the week.

The development the potato blight application increases convenience and information available to .The fungus thrived in the damp weather of Ireland and quickly spread through the air.

Being air-borne made the blight very bad because it not only spread over the fields killing the growing potato.
