Black dot has become an increasingly major issue in potato production, with recent studies highlighting its importance. The fungal pathogen responsible for this disease, Colletotrichum coccodes , is widely distributed across major potato-growing regions and in fields where alternative hosts are cultivated. The pathogen has a broad host range, including many economically important crops, several of which rank amongst the most w...

Physiological age (p-age) in potato seed tubers is a complex and dynamic biochemical process that strongly influences plant vigour, canopy development and final yield. Consequently, p-age is a major concern for both seed producers and growers because it directly affects seed quality and subsequent crop performance. Extensive research has characterised the physiological, biochemical, and hormonal mechanisms underlying tuber age...

Potato mop-top virus (PMTV) is a soil-borne virus that constrains potato production in temperate regions worldwide and has recently been detected in Australia, including north-west Tasmania. Infection occurs via roots and spreads systemically, but virus distribution within plants is uneven and symptoms are often absent. Tuber spraing, characterized by internal necrotic arcs and rings, is the most economically important symptom...
