The battle against potato black dot: A comprehensive review of two decades of research and management strategies
Cranfield and Aberystwyth Universities conducted a 20-year study on potato black dot disease management. Their research, spanning pre- and post-harvest strategies, aimed to identify knowledge gaps and improve disease control. The potato, a staple in global agriculture, faces threats from black dot, a fungus causing economic losses. The study emphasizes the importance of technological solutions, like machine learning, for early disease detection and effective intervention.
One bad potato can spoil the batch, which is why processor J.R. Simplot is reminding producers to beware of pink rot as they begin harvest, as Geralyn Wichers reports for Manitoba Co-operator. “If you know there’s rot in there, tell your harvest operator, ‘when you come to that low spot, pick up the harvester, drive over, and don’t harvest those certain areas,’” said Scott Graham, Simplot’s raw agronomy manager. The fungal disease has been an issue for a number of Manitoba producers in recent years, the company said.
Adrian Cunnington from Potato Storage Insight (PSI) offers guidance to growers on optimal potato storage. Emphasizing the significance of proper skin set and ventilation, he warns against the risks of blight and blackleg diseases reported pre-harvest. Quick storage with effective drying is crucial, especially amidst disease threats. Managing crop temperatures during loading and avoiding crop moisture are vital to maintain tuber quality and ensure successful storage.
Potatoes in South Africa have been affected by soft rot and blackleg due to higher than usual rainfall. These bacterial diseases, first identified in 1988, thrive in anaerobic conditions, especially in wet environments. The bacteria can survive in tubers, plant debris, and various plants but not for long in soil. Infected tubers initially show no symptoms, but under conditions like waterlogging, the bacteria multiply, leading to soft rot. Transmission can occur through infested tubers, water, or mechanical means.
‘Potatoes with the right antennas’: Origin of novel broad resistance to late blight found in wild potato relatives
Researchers from Wageningen University & Research, in collaboration with Tübingen and Norwich colleagues, have advanced our understanding of potato resistance against blight (Phytophthora infestans). Potatoes use receptors to detect and defend against the pathogen. While internal receptors (R genes) are well-understood, external receptors (PRR) need more research. A specific PRR receptor, PERU, shows dynamic evolution, challenging previous beliefs. Studying wild potatoes reveals evolutionary insights, potentially enhancing future potato resistance.

The Canadian Food Inspection Agency (CFIA) has concluded its investigation into the 2021 potato wart detections in Prince Edward Island (PEI). The U.S. potato industry welcomes the progress but emphasizes the need to halt planting in wart-infested fields. The CFIA and USDA APHIS are urged to address vulnerabilities highlighted in a 2022 APHIS report. Without action, the spread of PEI potato wart to the U.S. is deemed inevitable, risking significant economic impact.
Nearly two years after the U.S. market was closed to Prince Edward Island potato sales, the Canadian Food Inspection Agency has completed an investigation sparked by the detection of potato wart in two Island fields back in 2021. Over the course of the investigation, CFIA staff collected and analyzed nearly 50,000 soil samples from fields associated with those detections of the fungus, which disfigures potatoes and sharply reduces crop yield but is not harmful to humans.

Unpredictable weather and a tough potato season have escalated the threat of Alternaria in the UK. The disease has been detected earlier than usual, with crops already showing severe die-back. The reduced use of mancozeb and expensive fertilisers, along with extreme heat and light stress, have made crops more susceptible. Syngenta’s Technical Manager, Andy Cunningham, advises early preventative measures and the use of specific fungicides to combat the disease and protect unaffected plants.
A study by researchers at the International Potato Center focused on improving potato resistance to late blight (LB) by incorporating LB resistance from wild potato species into cultivated potatoes. The research involved techniques like rescue pollination and sexual polyploidization to transfer beneficial traits from wild potatoes to cultivated ones. The study resulted in the development of promising sexual and tetraploid hybrids with desirable traits such as high dry matter and LB resistance. These hybrids offer potential for future potato breeding strategies but further research is needed to validate their resistance and address any undesirable traits.
The Colorado potato beetle, a significant threat to potato crops, has been found in the UK for the first time since 1977. The beetle larvae were identified in a Kent field and confirmed by the Animal and Plant Health Agency (APHA). The APHA is working to eradicate the pest, which can strip potato plants of their leaves, and is conducting a survey to determine the extent of the infestation. The beetles are occasionally imported into the UK from continental Europe as ‘hitchhikers’ on non-host plant material, such as leafy vegetables, salad leaves, fresh herbs and grain.
