Plant Diseases and Climate


As a high school or undergraduate Biological Sciences teacher, you can use this set of computer-based tools to teach about plant diseases, plant pathogens, disease pathology in plants and the impact of climate on the incidence and severity of plant disease.

This lesson plan enables students to learn about plant pathogens and disease. Climate changes such as increasing atmospheric carbon dioxide concentrations and global warming not only affect the growth and cultivation of crops but also the reproduction, spread and severity of plant diseases. This lesson plan teaches about the influence of climate on plant diseases.

Thus, the use of this lesson plan allows you to integrate the teaching of a climate science topic with a core topic in Biological Sciences.

Learning Outcome

The tools in this lesson plan will enable students to:

  1. Define what are plant diseases and what are the factors influencing it
  2. Classify the various causal agents of disease in plants
  3. Distinguish between signs and symptoms of diseases in plants
  4. Describe the pathology of diseases caused by bacteria, viruses, fungi and nematodes in plants
  5. Understand the balance of the host-pathogen-environment triangle
  6. Discuss how climate change can impact the development of plant disease

Teacher-contributed lesson plan by Dr. Aditi Kothari-Chhajer, Dr. Amit Vashishtha and Dr. Neeti Mehla, Sri Venkateswara College, (Delhi University), India.
