Certainly! Here are some important questions and answers related to plant pathology: What causes plant diseases? Plant diseases can be caused by various factors, including pathogens such as fungi, bacteria, viruses, and nematodes. Abiotic factors like environmental stress, poor soil conditions, and physical injuries can also lead to diseases. What is the formal classification of fungi and bacteria, and how do they pose threats to plants? Fungi and bacteria are classified as microorganisms. Fungi are eukaryotic microorganisms, while bacteria are prokaryotic. They can threaten plants by infecting them, disrupting their cellular functions, and causing diseases. What are the symptoms of fungal and bacterial diseases, and how are they identified? Symptoms of fungal diseases may include wilting, leaf spots, powdery mildew, and fungal growth on plant parts. Bacterial diseases may manifest as leaf yellowing, cankers, and ooze from lesions. Identification is often based on visual symptoms and laboratory tests. What are some measures for plant disease management? Plant disease management measures include cultural practices (crop rotation, sanitation), biological control (using beneficial organisms), chemical control (fungicides, bactericides), and breeding for disease resistance. What is the impact of organic and agricultural practices on plant diseases? Organic practices, such as using compost and natural predators, can reduce the incidence of plant diseases. Conventional agricultural practices often rely on chemical control methods, which can have environmental implications. What are some industrial techniques used for studying plant diseases? Industrial techniques for studying plant diseases include DNA sequencing, polymerase chain reaction (PCR), and high-throughput screening to identify pathogens and develop disease-resistant crops. List some common diseases of flowers and fruits in common plants. Common diseases include powdery mildew, downy mildew, gray mold (Botrytis), bacterial spot, and various viral diseases, depending on the specific plant species.
