A disease in plants is a condition that disrupts the normal functioning of a plant, often caused by pathogens such as fungi, bacteria, viruses, or nematodes. Plant diseases can also arise from environmental factors, such as nutrient deficiencies, extreme temperatures, or water stress. These diseases can lead to symptoms like wilting, chlorosis (yellowing of leaves), stunted growth, lesions, and ultimately reduced yield or death of the plant. Effective management of plant diseases often involves a combination of cultural practices, resistant plant varieties, and, when necessary, chemical treatments.
