A curator is labelling three specimens for a plant-health teaching collection.
The first specimen is a leaf with pale patches that reduced photosynthesis in the plant. The record states that the cause was viral.
Name the viral disease shown by this specimen.
The second specimen is a leaf from a flowering garden shrub. Dark spots developed on the leaf, which then turned yellow and fell from the plant. The record states that the cause was fungal.
Name the fungal disease shown by this specimen.
The third specimen is a small insect with sharp mouthparts. In life, it took sugary sap from the phloem and could carry pathogens between plants.
Name this insect pest.
