Plant pathogens: control (poster and presentation)

The poster ‘Plant Pathogens: Control’ illustrates the many ways that we control plant pathogens, from polyculture farming to controlling the import of plants. The poster is accompanied by a presentation, which can be used as a step-by-step walk-through of the ideas in the poster.

The Battle for Fortress Plants (poster and presentation)

The poster ‘The Never-Ending Battle for Fortress Plant’ illustrates ideas about plant defences against pathogens. It depicts the plant as a fortress which is defended against invading pathogens. The accompanying resources explore this idea.

Plant disease - Fighting for Survival (post-16)

In this worksheet and case study, for post-16 students, students develop their understanding of communicable plant disease and how plants respond to infection. It addresses the plant related learning outcomes in the OCR Biology A specification, section 4.1.1 ‘communicable diseases, disease prevention and the immune system’.

Plant disease detectives

In this activity, designed for the new GCSE biology specifications, students act as detectives, piecing together information from the sources provided to identify common plant diseases, and how to stop the spread.

Plant disease practicals - identifying the cause of brown rot

In this practical activity, suitable for the new GCSE specifications, students explore how the technique of re-infection (using infected material to infect healthy plant tissue) can help to identify the cause of a plant disease.

Plant disease practicals - powdery mildew

In this practical activity, designed for the new GCSE specifications, students collect samples of leaves showing samples of infection with powdery mildew, and send them to the powdery mildew survey for analysis.

Plant disease practicals - Investigating violet bramble rust

In this practical activity, designed for the new GCSE specifications, students use magnification to examine leaves showing symptoms of a common plant disease, and produce labelled drawings of the fungal spores.

How healthy are your trees?

This activity is designed to get students thinking about plants as living organisms that have to survive, breed and defend themselves against disease. Students begin by cataloguing the health of trees in the area, and can then follow this with a statistical investigation.

CSI Trees - investigating plant pathogens

A sickly tree might not look like much of a crime scene, but the influx of pathogens on plants is causing increasing concern in the UK. In this resource, students take on the role of plant pathologists, asking questions to determine the cause of a tree's death.

Student Sheet 18 - Koch's Postulates

Robert Koch was a bacteriologist who lived from 1843 to 1910. In his work on diseases, he was trying to establish whether a microbe, obtained from a diseased patient, was in fact the cause of the disease. This protocol allows students to demonstrate and test Koch’s Postulates, using apples infected with the fungus Penicillium expansum.

The SAPS ELISA kit for Botrytis

The SAPS ELISA kit for Botrytis has been developed as a low cost way to bring practical immunology into the classroom, including equipment, the necessary antibodies, the substrate and a Botrytis culture
