Heat and smoke impact Idaho potato sizing

Sizing looks to be an issue in new crop potatoes from Idaho this season. Ryan Wahlen of Pleasant Valley Potato in Aberdeen, ID says it’s been in new crop now for just under three weeks. “We started about a week later than normal,” he told Astrid Van Den Broek of FreshPlaza. “The heat we experienced this summer just delayed things. We were hoping to get a little bit more size out of the potatoes so we waited a week. But even with that, the size and the yields weren’t there.”

Heat leaves Canada’s prairie potato growers on edge

Producers across Western Canada are optimistic they can still produce a good crop this fall if the weather co-operates, reports Alex McCuaig for The Western Producer. It’s been a reversal of fortunes for Canada’s potato growers this year as last year’s dry season in the East moves west. Not all Manitoba growers have escaped the heat that has plagued producers across the West, especially those farming on dryland.

Idaho drought: Potato digs show ‘bad signs’

Heat and dryness have been the story of the summer this year in southern Idaho. With record heat, crops — including Idaho’s most famous crop — have seen effects in numerous ways, reports Nicholas Snider for KMVT. “I’m not saying that Idaho won’t have any of the bigger potatoes they’re famous for,” says Sean Ellis, a spokesman for the Idaho Farm Bureau Federation. “There’s just not going to be as many this year.”

Weather woes hit British potato crop

Potato growers in the UK are starting to lift a crop that has weathered difficult conditions and is being sold into an uncertain market, writes Cedric Porter in an article for Farmers Guardian. Porter says most potatoes were planted in very good conditions as the wet winter gave way to a drier spring just in time. But it was one of the coldest April’s on record, followed by a very wet May and then a mixed summer with some heat but plenty of rain.

Idaho potato growers brace for ‘inferior crop’

Randy Hardy, of Oakley, is not alone among Idaho farmers in his assessment that the potato crop he’ll soon harvest will be the worst of his career. Spud farmers conducting test digs or early harvest are uprooting plants supporting no tubers. Where there are spuds, there are fewer than normal, and most of the tubers are undersized and misshapen.

Prairie farmers struggle as drought set to become ‘among worst in Canadian history’

This year’s drought is on its way to becoming the worst the Prairies have ever recorded and the worst ever in Canada, according to John Pomeroy, Canada research chair in water resources and climate change at the University of Saskatchewan. It is already worse than a severe drought in 1961, he said. “It’s early to call it the most severe [drought] at this point, but it certainly has all the hallmarks of heading in that direction.”

Summer heat means Idaho farmers are seeing shrunken spuds and onions

Harvest season is underway across the northwest, and farmers in some areas are seeing smaller spuds and onions because of excessive heat earlier this summer. Ben Josephson of Idaho Falls-based Wada Farms said it’s too early to know for sure how everything will turn out this harvest, but so far, some of the Idaho Russets coming out of the ground near Mountain Home and Bruneau are smaller than usual.

Farmer Ambassador: ‘Farmers like me want to join the fight against climate change. But we need help’

Vanessa Kummer is a farmer from Colfax, North Dakota. She is a Farmer Ambassador with Farm Journal Foundation. In a recent article published as a CNN Opinion piece, she writes: The agricultural industry is often misunderstood by the general public, and we haven’t always been credited for being forward thinking on climate change. However today, more farmers recognize the evidence around us and are turning the tide. …To truly move the needle, the government needs to provide more support.”

Irrigation now in use to maintain potato yields in Ireland

According to Wilson’s Country agronomist Stuart Meredith, up to 30% of potato crops in the Republic of Ireland are now being irrigated in order to maintain yields. The equivalent figure for Northern Ireland is 10%. The continuing warm spell has created significant moisture deficit challenges for most Irish potato crops.

Survey: European farmers view climate change as main challenge for future potato production

Europatat is part of an international consortium involved in the research project ADAPT (“Accelerated Development of multiple-stress tolerAnt PoTato”), which aims to develop new strategies for making potatoes fit for the challenging production conditions of the future. ADAPT asked farmers about their perception of climate change, their experiences concerning its impact on potato production, and their need for adapted potato varieties. Almost 90% of the survey respondents indicated that climate change had affected their potato production in the last 10 years, and almost 50% defined climatic change as a threat to maintain potato production at their farms.

Heat wave hits record 46.6C in Canada as US north-west also sizzles

Canada has recorded its highest ever temperature as the country’s west and the US Pacific north-west frazzle in an unprecedented heatwave. The US and Canada have both warned citizens of “dangerous” heat levels that could persist this week. A “heat dome” – static high pressure acting like a lid on a cooking pot – has set records in many other areas. This high pressure zone is huge, from California right up to Canada’s Arctic territories and stretching inland through Idaho.

‘Heat dome’: Hot temperatures will impact crops and animals

As the Magic Valley prepares for potentially record setting heat this week, farmers, potato researchers and dairy scientists are all voicing concerns. Nora Olsen, University of Idaho professor and extension potato specialist, said heat on top of longer days can be a lot for any crop, including potatoes. In high temperatures, potatoes will shut down and stop growing. This can cause situations of start and stop growth patterns that are not ideal for growing potatoes. “We are like pulling our hair out right now trying to figure out how to irrigate the crop,” she says.

Spray coverage crucial in crusade against blight, says potato specialists

With resistance to fluazinam now established in the blight populations in the UK and a continuing shift towards more aggressive P. infestans populations such as 36_A2 and 37_A2, a robust resistance management strategy is essential to safeguard crops. SRUC specialist in blight epidemiology Dr. Ruairidh Bain, believes that spray coverage is one of the key factors of the blight control programme that needs to be improved to protect potato crops.

The ‘touchy-feely’ potato: Researchers developed bio-sensor to detect early signs of plant stress

In an effort to increase agricultural productivity and limit waste, a team of researchers from the Hebrew University of Jerusalem (HU)’s Robert H. Smith Faculty of Agriculture, Food and Environment developed a method to detect signs of stress before potato plants are damaged. By employing genetic engineering, the team introduced a new gene coded to a fluorescent protein that reports the level of reactive ‘oxygen specieses’ – highly reactive molecules whose accumulation signifies stress responses.

Sunshine and warmth needed to aid Irish potato crop development

Domestic consumption remains buoyant and retail demand remains strong, especially with the colder weather Ireland is experiencing for this time of the year, the Irish Farmers Association (IFA) reports. This cold snap is also affecting the growth of early and maincrops. Recent rainfall has helped in many parts of the country but it is verging on too much, sunshine and warmth is now needed to aid crop development. There are many reports indicating that it will be a ‘late year’.

Potatoes exposed to heat stress: Hot spots point to targets for Quantis biostimulant treatment

Rising temperatures resulting from climate change is exposing more potato crops to the damaging extremes of heat stress more frequently. A study of trends has shown it is temperate climates, including the UK, that are bearing the brunt of some of the extremes in weather changes. However, analysing weather data on a more local level can indicate crops that are most at risk of heat stress, and how to adapt agronomy to cope, advocates Syngenta Head of Technical, Dave King.
