The latest Irish Farmers Association report underscores the difficulties Irish potato farmers face due to unpredictable weather, causing planting delays and a potentially late harvest. Despite these challenges, retail demand and home consumption remain strong, pressuring old season stocks and driving up physical prices. This trend is seen across Europe, with weather impacts noted in the Netherlands and the UK.
The federally funded “Potato Virus Initiative” aims to combat Potato Virus Y (PVY) and Potato Mop-Top Virus (PMTV) through collaborative research involving over 25 researchers. Led by the University of Idaho, the project focuses on virus management strategies, detection methods, breeding resistant varieties, and effective in-season management. Key findings include advanced detection methods, optimal post-harvest detection, innovative treatments for dormancy break, soil microbiome insights, and breeding for resistance.
Amid concerns about glyphosate, the most used herbicide globally, scientists struggle to find safe, effective alternatives, according to a Genetic Literacy Project (GLP) article by Andrew Porterfield and Jon Entine. Their analysis reveals exaggerated health concerns and underscores glyphosate’s proven safety. However, existing substitutes lack efficacy, increasing costs and environmental risks. The authors argue for a balanced, research-driven approach to replacing glyphosate.
UK potato prices have surged due to a low 2023 harvest and delayed planting, with English White potatoes now at £630/MT, showing a 90% increase, and Maris Piper potatoes at £660/MT, up by 120%. Market analyst Harry Campbell at Mintec writes that despite warmer May weather improving planting, supply constraints continue, leading growers to hold stocks in anticipation of prices reaching beyond £700/MT. The market remains primarily a sellers’ market.
Researchers have found that calcium significantly boosts resistance in potatoes against bacterial wilt, a pathogen impacting global potato production with annual losses of $19 billion. The study demonstrates calcium’s potential as soil amendments to counter bacterial wilt. Researchers noted a correlation between calcium levels and disease resistance, suggesting new integrated disease management avenues with focus on calcium enrichment strategies. This could lead to advances in potato breeding and agricultural practices aimed at enhancing disease resistance.
This week, potato farmers in Ireland and Europe face significant challenges due to erratic weather, affecting planting and crop progress as reported by the IFA. In Ireland, brief dry spells were insufficient for sustaining continuous planting, leading to potential supply issues in summer. Similar issues are observed across Europe, with France and neighboring countries experiencing severe planting delays. The IFA stresses the importance of strategic planning to mitigate weather impacts on agriculture.
A study by researchers at Agriculture and Agri-Food Canada, published in Frontiers in Plant Science, reveals significant challenges potato cultivation faces due to climate change. The research team underscores the importance of developing stress-tolerant potato varieties to maintain global food security amid rising temperatures, drought, and increased pest incidences. The study includes advancements in understanding potato plants’ molecular responses to environmental stress, critical for breeding resilient cultivars.
Potatoes, despite their versatile use in food and non-food sectors, have seen a dramatic 71% decline in UK’s fresh potato demand since the 1970s. According to a report by SRUC, Scotland remains more stable in potato production compared to the entire UK, accounting for significantly higher portions of seed potatoes, crucial due to its disease-free status. Scotland’s seed potato sector, highlighted for its economic importance, supports substantial employment and generates significant economic output.
A comprehensive study from the University of Guelph and SunRISE Potato reveals motivators and barriers in adopting best management practices (BMPs) among Ontario’s potato producers. Enhanced by a System Thinking approach, the research indicates that personal values largely drive adoption, yet structural challenges like market access and stringent regulations hinder it. Insights from this study can inform targeted strategies to improve BMP adoption and enhance sustainable agriculture.
The United Potato Growers of Canada reported that potato holdings in April 2023 increased by 12.5% from the previous year, totaling 52,393,000 cwt. Stocks are higher than the five-year average, with significant amounts in western provinces, especially in processing. Quebec and Maritime regions saw lower stocks due to a rainy season. Processing sector stocks surged by 24% due to record production. Meanwhile, overall seed sector stocks are slightly down by 5.6%.
The International Potato Center, backed by CGIAR, launched a survey to improve food security in the Global South by developing resilient potato varieties. It seeks data from various agricultural stakeholders to tailor breeding programs to regional needs, thus enhancing yield and sustainability. This effort combines market needs analysis, sustainable practice evaluation, and understanding farmer and consumer preferences to address climate impact on food systems.
Sarah Light and her team studied how potassium chloride application timing affects potatoes, finding that fall applications don’t increase plant chloride and may reduce chloride accumulation since it leaches below the root zone. Their research indicates no significant impact on nitrogen levels, yield, or tuber specific gravity, regardless of fertilizer timing. The study, funded by the USDA’s National Institute of Food and Agriculture, contributes to optimizing fertilizer use in agriculture.
Potatoes, the world’s fourth most important crop, are under threat from climate change, with rising temperatures, erratic rainfall, and extreme weather challenging production. This article by Lukie Pieterse reviews strategies for enhancing potato resilience, such as breeding climate-tolerant varieties and adopting biotechnology and sustainable practices. Collaborative efforts are vital to secure this staple food’s future, ensuring global food security amidst a changing climate.
Researchers from the University of Prince Edward Island predict significant declines in potato yields due to climate change. Published in the journal Foods, the study forecasts a 6-10% decrease in yields under low-emission scenarios, and up to a 60% drop by the 2070s under high emissions, possibly reaching an 80% reduction by the 2090s. The study underlines temperature increases and variable precipitation as major factors affecting growth and urges the implementation of adaptation strategies.
Persistent wet weather is causing serious planting delays for Irish potato farmers, warns the IFA. This has led to fears of supply shortages and rising consumer prices due to low harvest and strong demand. The situation is mirrored in the U.K., with similar hindrances in planting. European markets are tight, with imports of new-crop potatoes from Israel and Egypt increasing.
The Union of the German Potato Industry (UNIKA) and the German Potato Trade Association (DKHV) have commissioned a significant literature review focused on the carbon footprint associated with potato cultivation and processing. The review showed potatoes have a lower carbon footprint than cereals, with the potential for further reduction. This study found processing increases emissions, and variables like fertilizer use impact the footprint, highlighting the crop’s role in sustainable food production.
Terra Carbono, an innovative Hungarian ag-tech company, focuses on sustainable potato cultivation, aiming to reduce carbon footprints and improve agricultural productivity. They create biodegradable, carbon-negative products that boost yield, conserve water, and minimize chemical use while enhancing soil health. Terra Carbono is engaged in several partnerships for community betterment and sustainable practices.
Extreme weather in Ireland is causing delays in potato planting, impacting the national economy. The Irish Farmers Association reports excessive rainfall leading to minimal progress and potential market shortages. Similar issues are occurring across Europe, constricting current potato stocks with main processors trying to mitigate supply chain disruptions. The situation reflects the strong link between climate and agricultural stability.
