Agricultural pathogen problems
Plant diseases are conditions that impair the normal function, growth, or appearance of plants, caused by pathogens such as fungi, bacteria, viruses, or environmental stresses.
Farmers and gardeners watch for telltale signs like wilting, discoloration, spots, or abnormal growths.
Some plant diseases have devastated crops throughout history, such as the potato blight that caused the Irish famine.
The tomatoes succumbed to early blight, a common plant disease in humid climates.
