Development activities cover a wide range of diseases. For example, past studies have identified the store as a source of contamination for healthy stocks by a number of pathogens; spread of gangrene fungus in aerosols generated by rain; effectiveness of various fungicides controlling tuber rots and blemish diseases; detection of fungicide resistant strains; survival of potato pathogens in field soils, development of test methods to recover tuber pathogens from soil and characterisation of late blight populations in Scotland.
