Scientists at the Basque Institute for Agricultural Research and Development, Neiker-Tecnalia have for the first time identified the existence in Álava-Araba of the two sexual types A1 and A2 of the fungus Phytophthora infestans, responsible for potato blight. The experts have been able to confirm that the crossing between the two types leads to variants that are more resistant to conventional fungicides and can survive in adverse conditions of temperature and humidity for months and even years on end. The R&D centres experts warn of the possibility of crossing between types A1 and A2, which would lead to rapid, significant changes in the population of the Phytophtora infestans fungus with the appearance of new, more aggressive strains resistant to routine phytosanitary teatments.
Oostenrijkse handelaren en telers hebben nog steeds een en ander aan aardappelen in opslag liggen, meldt de Oostenrijkse website Bauernzeitung.at. De verkoop verloopt weliswaar gestaag, maar de verkochte hoeveelheden blijven daarbij echter te overzien. Met de kwaliteit van de voorraden is men voor midden april meestal zeer tevreden.
Potato planting is about to begin, or has already started, in the main production areas in France. The Unpt (National Union of Potato Producers) has expressed concern about a further increase in planted area expected in the 2014/2015 season. Definitive figures will be published mid-June. ''Whilst aware that weather conditions in months to come will have a major influence on the yield'', the Unpt considers that ''the rise in acreage will have an impact and that needs to be considered in the development of total production''. They encourage each producer to ''ensure that they produce the quantity and quality for an outlet, adapted to their buyer. It is the responsibility of everyone, producer or fresh or industrial market operator, to set themselves an aim to maintain an offer-demand equilibrium''. (Source: Freshplaza.com)
Size matters for ware potato growers and tubers that are too big or too small for your customer means less saleable yield and less profit. However, Staffordshire spud producer James Daw is aiming to use the latest precision farming methods to iron out those extremes to boost yields and reduce waste. GPS yield mapping has been a popular feature of new combine orders for some time and Mr Daw has been mapping the output of the combinable crops on his 1,000ha of land for a number of years to target inputs such as seed and fertiliser.
New research shows that potatoes will still the produce tuber when times get tough. Agricultural Research Service agricultural engineer David Fleisher and colleagues wanted to measure how potato plants would respond to elevated atmospheric carbon dioxide (CO2) levels and the increasingly erratic rainfall patterns expected to result from global climate change. So the team conducted two outdoor-chamber studies to evaluate effects of short-term drought cycles at current and elevated CO2 levels. Fleisher and his research partnersplant physiologist Richard Sicher, soil scientist Dennis Timlin, research leader V.R. Reddy, and research associate Jinyoung Barnabyall work at the ARS Crop Systems and Global Change Laboratory in Beltsville, Maryland.
Once again, the weather is influencing the horticultural market in Argentina and is having negative effects on the price of potatoes. In recent days, as a result of the storms and the floods in production areas, the price of a box of potatoes increased by more than 30% in Tucumans Mercofrut, the main wholesale and retail centre of in the provincial capital. Juan Carlos Medina, vice president of Mercofrut, confirmed this by saying that the bulk price of potatoes had increased from 80 pesos to 110 pesos; a price increase that was transferred to the consumer in the vegetable markets. Its raining all over the country. Production areas are flooded right now. The price, however, will go back to normal when the weather gets better, but this wont happen overnight, said the manager. The potatoes marketed and consumed in the local market during this time of year come from Buenos Aires, Cordoba and Catamarca. We still have stock; we did not run out of merchandise due to last weekends shipments, he said. (Source: Freshplaza.com)
Aardappelen gedijen goed in tropische hooglanden, maar de lokale boeren weten de productie niet op te voeren. Het gewas wordt geplaagd door een veelheid aan ziekten en het genereren van meerwaarde zit er dan ook niet in. Nederlandse experts bieden uitkomst en voor de Nederlandse pootgoedhuizen levert het soms nieuwe afzetmarkten op. Aardappelen zijn gezonder dan rijst, banaan en cassave en kunnen een belangrijke rol spelen bij de voedselzekerheid in tropische hooglanden, maar aan de teelt en afzet kan nog een hoop worden verbeterd. De Wageningse aardappelspecialist Anton Haverkort en collega Romke Wustman kunnen vaak al in een week met een oplossingsrichting komen.
A three year Potato Council-funded study has just been completed which has evaluated the irrigation requirements for a range of varieties for tuber quality, while also accessing the impact to beneficial soil microorganisms. Start dates for irrigation have become earlier in the life of the crop. The main driver for this has been quality and the control of common scab in both the pre-pack and processing sectors where tolerance levels have markedly declined, explains Potato Councils water specialist Chris Steele. Scab-forming Streptomyces can multiply significantly in number on and around developing tubers in the period after initiation, a key time for common scab control.
In response to questions from the US government, industry officials provided the latest information regarding efforts to maintain and reopen the Korean market for US fresh potatoes. Those discussions included ensuring chipping potatoes from the Pacific Northwest could continue to be imported at the end of this season and the lack of progress on restoring table stock access from the Pacific Northwest and several other states. New access for additional states was also raised. The US government is expecting a response to a March 2014 letter on all of these issues by the Korean government in the coming months.

Last week, USDA's Animal and Plant Health Inspection Service (APHIS) announced the allocation of funds provided by the 2014 Farm Bill designed to prevent the introduction or spread of pests and diseases that threaten U.S. agriculture and the environment. The distribution includes more than $1,175,000 in funding for 13 states to survey, contain, and/or develop management or control techniques for potato cyst nematodes and globodera nematode pests. States receiving funding include: Idaho, Maine, Michigan, Minnesota, Montana, Nebraska, Nevada, New York, North Dakota, Oregon, Washington, Wisconsin, and Wyoming. The National Potato Council (NPC), as a co-chair of the Specialty Crop Farm Bill Alliance, worked with state partners during the 2004 Farm Bill debate to secure these vital finds to protect the future of the industry.

According to Potato Council, seasonal aphid flight data has started to appear for this season and the annual challenge of interpreting aphid population against resistance data and appropriate treatment comes to the fore once more. Temperatures in January and February were considerably higher than the long-term average across the country (by 1°C to 1.5°C in the north and around 2°C in the south) and it is estimated the first flights of many important aphid pest species could be two to four weeks earlier than average. These early forecasts relate to aphids that overwinter as larvae and adults, not as eggs, and largely relate to the cabbage aphid, peach-potato aphid and the potato aphid, and predict that these species should appear relatively early this year.
In België lag begin deze maand nog één miljoen ton aardappelen van oogst 2013 achter de planken. De totale voorraad is hiermee 140.000 ton hoger dan het vijfjarig gemiddelde begin april, zo blijkt uit de cijfers van een voorraadinventarisatie van het PCA en Fiwap. Het is bovendien de op één na hoogste voorraad ooit. Alleen in 2012 lagen met 1,1 miljoen ton van oogst 2011 meer aardappelen in voorraad.
Maintaining the quality and health of stored potatoes is vital for growers, processors and consumers but each year there are consistent and substantial losses due to storage diseases. The Lonestar portable freshness monitor can detect volatile chemical signatures associated with bacterial diseases such as blackleg and potato soft-rot in real time. This allows the early detection and isolation of rotten potato stock, helping to prevent further losses.
Bangladesh's potato exports have reached an all-time high, thanks to greater market opportunities in Russia that has banned potato imports from Pakistan over pest risks. Around 54,000 tonnes of potato had been shipped abroad in the nine months till March of the current fiscal year, up from about 28,500 tonnes in the previous fiscal year, according to the Plant Protection Wing of the Department of Agricultural Extension (DAE).
The Idaho State Department of Agriculture has imposed new temporary rules at the potato industrys request governing bacterial ring rot, including mandatory reporting of its detection. The regulations, which took effect Feb. 26 and must be finalized during the next legislative session, also require BRR testing before exporting Idaho potato seed, enact new record-keeping requirements for commercial seed cutting and give ISDA authority to prevent replanting of BRR-tainted seed. Last season, Idaho experienced a flare-up of BRR, which is highly contagious and financially devastating for growers.
Potato growers have warned that consumers could be left with a $100 million compensation bill if the State Government acts on advice to deregulate the industry. The Potato Growers Association of Western Australia is digging in for another fight to stop deregulation following the release of a draft report on microeconomic reform.
Pringles potato chips, which were invented by Procter & Gamble Co. and eventually included a zero-calorie fat substitute called olestra that P&G developed in collaboration with the University of Cincinnati, might have medicinal qualities, according to UC researchers.
Donegal Investment Group, formerly Donegal Creameries, has reported increased revenues and after tax profits for last year. Revenues for the year to the end of December rose by 8.1% to 86.7m, while profit after tax from continuing operations grew by over 10% to 4.85m. Donegal said the results reflected further progress on its new strategy when it decided to reposition itself around a more focused and streamlined group of businesses with seed potatoes at its core.
Door de gunstige weersomstandigheden van de afgelopen periode zijn al veel aardappelen van de hoofdoogst geplant. De gemiddelde temperatuur in maart bedroeg 8,4 °C, in maart 2013 was dat gemiddeld 2,5 °C. Zeker t.o.v. vorig jaar april is er al veel geplant. In Nederland is men verder met de pootwerkzaamheden dan in België, Frankrijk en Engeland. In Duitsland is men verhoudingsgewijs verder en kunnen als het meezit rond Pasen alle aardappelen in de grond zitten.
A southeast Idaho potato farmer changes his farming practices after dealing with bacterial ring rot. Russell Fehringer has implemented tough new farming policies and procedures in his fight against ring rot, and constant cleaning and sanitizing of equipment and facilities will now be the norm.
