Which of the following is a common symptom of plant disease caused by pathogens?

Spotted foliage is a common symptom associated with plant diseases caused by various pathogens, such as fungi, bacteria, and viruses. These spots often indicate the presence of necrosis or chlorosis resulting from infections, and their appearance can vary significantly depending on the specific disease and the affected plant species. Various pathogen types can lead to distinct patterns of discoloration or lesions, which is why gardeners and arborists often look for these signs when diagnosing plant health issues. Recognizing spotted foliage as a symptom can prompt further investigation and, if necessary, the implementation of appropriate management practices to mitigate the effects of the disease. This is critical in maintaining plant health and preventing the spread of pathogens to other plants in the area.
