Infectious Diseases

Examine a variety of plant specimens to understand the impact of pathogens and insects as well as the responses of plants to disease.

Explore the ways that plant diseases spread and how an understanding of these processes allows people to control plant diseases.

• Examine infected plant material to observe different types of pathogens and the symptoms caused.
• Discover the defence adaptations of plants, the role of quarantine and strategies used to control plant diseases.
• Learn the symptoms, impacts and disease control strategies for plant diseases.

• Discuss ways that disease affects plants and the impact this can have on ecosystems and human society.
• Investigate the ways diseases are identified and controlled by prevention and treatment strategies.
• Explore the steps used in the quarantine process and examples of diseases controlled by these methods.
• Research plant diseases considered a threat to ecosystems or agricultural trade.
