Historical development, fungicides, disease management, and important plant diseases for competitive exams.
This course covers major crop diseases, causal organisms, disease symptoms, disease cycle basics, fungicides, biological control options, and integrated disease management concepts used in agriculture competitive exams.
Plant diseases are caused by pathogens such as fungi, bacteria, viruses, and nematodes, while insect pests directly feed on plants or plant products. Exams often test both separately through symptoms, signs, and control measures.
Disease identification is important because many questions are crop-wise and symptom-based. Recognising classic examples like blast, rust, wilt, smut, blight, and mildew helps in solving both objective and matching questions quickly.
Start with basic pathogen groups and disease terminology, then move to important diseases of cereals, pulses, oilseeds, vegetables, and fruit crops. After that, revise fungicides and integrated disease management principles.
