Fight against powdery scab: South African researchers identified two ideal plant species for potato crop rotation
A study by researchers in the Potato Pathology Programme at the University of Pretoria identified oat and soybean as “ideal to be included as trap crops in rotations with potatoes”. This is a first study in southern Africa on alternative weed and cultivated hosts of the cercozoan Spongospora subterraneaf. sp. subterranea, which causes the potato disease powdery scab.
Maleic Hydrazide (MH) is a potato sprout suppressant that was first identified as a plant growth regulator in the 1940’s. In an article published by AHDB Potatoes this week, it is said that the reduction in permitted treatments rate for CIPC have driven an increase in MH use in recent years. Interim data from AHDB at Sutton Bridge has shown that in the absence of CIPC, MH can offer good sprout control and boost efficacy of alternative treatments when used in combination with them.
Neonicotinoid insecticide resistance: Practical guidelines for growers to test product effectiveness
All commercial potato growers are aware of the fact that some pests have been shown to develop resistance against some of the commonly used insecticides available to combat them. In a recent article published by Spud Smart magazine, renowned potato specialist with the Ontario Potato Board in Canada, Dr Eugenia Banks, provides growers and agronomists with practical guidelines on how to conduct on-site tests to determine product effectiveness against Colorado potato beetles in their area and specific situation.
The sprout suppressant DMH is currently going through the registration approval process in the UK. AHDB says it is hoped this may expedite the availability of DMN to industry but, at this stage, there are no guarantees the application will be successful or what the terms and timeframe may be.
Latest Canadian Crop Report: Good potential, but hard work needed to clean up old crop later than normal
The Crop Transition Conference has been held for the past 12 years in Minneapolis. This year, due to COVID-19 restrictions, it was held virtually, says Kevin MacIsaac, General Manager of the United Potato Growers of Canada (UPGC). In conclusion it is said that “The crop has good potential, but we are going to need to work hard, to clean up the old crop at a later than normal date, as the new crop transitions in on schedule.”
Disease-suppressive crops work in multiple ways: by not being a crop host to the disease, by actively lowering pathogen levels, and by boosting soil health so the overall growing environment is more resilient to disease. Robert Larkin, USDA-ARS research plant pathologist, joins Potatoes in Canada for this podcast to discuss the different ways crops can lower disease pressure, what farmers in Maine are doing, and all about soil health more broadly.
Investigative Report: Potato production in Egypt – ‘Export demands increase interest in bio-pesticides’
GROPRO Corp. a US based producer and supplier of biological crop protection products, has recently completed a investigative agricultural tour of Egypt. According to the group of specialists from GROPRO, “We believe that bio crop protection products will play an important role in the near future to assist in developing the Egyptian potato industry – not only to improve the efficiency of crop production in general, but for farmers to attain better quality products and higher yields.”
Hutton periods are now being recorded in England and the focus needs to shift to blight control in potatoes. Recent changes to the UK blight population over the last couple of years have revealed more dominant aggressive strains with higher spore production and faster life cycles. Coupled with the emergence of the fluazinam-tolerant blight strain 37_A2, this makes decisions around[Read More…]
Éco+ is proud to present its bestselling natural biostimulant, Nutrisorb2.0. There is still time to apply Nutrisorb2.0 to potato crops, fresh or processing varieties. Marc Richard, President of Eco+ says. “We all know that timing is everything and now that you have planted, it is important to make the sugar movements reach the tuber in a consistent, stable manner. Nutrisorb 2.0 also helps move calcium in the plant which is difficult at the best of times.”
United Potato Growers of Canada: Planting conditions favourable for potato growers in most parts of the country
While concerns about increased inventory due to declining consumer demand are top of mind for many growers as they finish up planting the 2020 crop, the general manager of United Potatoes Growers of Canada said most regions of the country are catching a break from Mother Nature.
Hyperspectral imaging, a growing area in remote sensing, holds the promise of providing a solution for crop monitoring over large areas, and scientists at the James Hutton Institute are working with partners in industry and academia to investigate the potential of the technology to maximise the sustainability and productivity of key food crops. The InnovateUK-funded project “In-field Optical Detection of Potato Disease” primarily explored the utility of aerial imaging (drone captured multispectral and high-res RGB) to detect and differentiate between a selection of economically important potato diseases.
Rhizoctonia control is set to become much more difficult for potato growers with news of a second seed treatment being withdrawn, just weeks after the loss of Monceren. EU regulators have recommended the withdrawal of penflufen, a fungicide contained in the powder seed tuber treatment product Emesto Prime DS. It is used to control Rhizoctonia solani, which causes stem and stolon canker and black scurf in potatoes.
The U.S. Department of Agriculture has re-opened a public comment period on changes to regulations of pale cyst nematode-infested areas, according to a report by Chris Koger of The Packer over the past weekend. Pale cyst nematodes (PCN) affect potato crops. The USDA’s Animal and Plant Health Inspection Service took initial comments twice in 2019, and is accepting comments until July 6 “on the science supporting the protocols, including the sources of the methods informing their content,” according to a USDA news release.
A carbon footprint tool, which aims to help farmers reduce their greenhouse gas emissions, has been updated to include a soil sequestration module, according to a report by Tillage & Soils. Agrecalc was developed by SAC Consulting – part of Scotland’s Rural College (SRUC), in response to the growing need for a simple-to-use, accurate and science-driven carbon audit tool.
UPGC: Difficult two months with unexpected oversupply of processing potatoes as fry sales decrease during pandemic
According to the latest market report issued by the United Potato Growers of Canada (UPGC), many Canadian potato growers have been dealing with a difficult two months with an unexpected oversupply of processing potatoes as a result of decreased sales of French fries, as sit-down restaurants shut down during the COVID-19 pandemic.
It is of course already well known that blight is a constant threat and significant cost to potato growers. To offset blight, British potato growers should put plans in place as early as possible with their Basis agronomist to ensure a proactive approach is taken to prevent the disease, according to a report published by the Newsroom at Farming Life. In order to achieve putting less pressure on fungicides it is important that good Integrated Pest Management principles are applied for blight control. The most important thing when spraying to prevent blight is to start your programme early.
The IFA reports that the market situation remains largely unchanged in Ireland. Early liftings continue this week in the country, with drought conditions hindering yields in many areas. Irrigation is a key concern for all growers at present. Drought is a key concern across Europe. The drought in the Netherlands is seen as worse than that of 1976
Brad Carlson of Capital Press reports that a spore-sampling network designed to detect airborne diseases before they impact southern Idaho crops has been enhanced this year, its third in operation. Faster detection and reporting, and the ability to find more types of disease that could threaten potatoes and other crops, are among the benefits.
One country that has routinely been in the news for their impressive handling of the outbreak is South Korea. In Canada, the closure of the hospitality sector in light of the coronavirus caused a significant threat to potato growers. The potato growers in the USA too have faced significant challenges with accessing markets and oversupply. This issue of excess potatoes is impacting supply chains across Europe too. Belgium is famous the world over for its fries and UNESCO list them as a Cultural Treasure. Given the closure of restaurants, including the ubiquitous fish n’ chip shops of most high streets, potato growers across the UK are struggling to sell their crop.
Potato yields from the early Jersey Royal crop are down 40% as drought grips the Chanel Islands in bone dry conditions not seen since the drought of 1976. A very wet February was followed by virtually no rain through March and April, and the season on Jersey is running three or four weeks behind the normal lifting schedule.
Potato production in Tenerife will significantly decrease this year due to a wind storm that hit the island in late February, which wiped out a good part of the extra-early potato crop. And then there was also damage done by the Guatemalan moth plague that has been affecting Tenerife farmers for more than 20 years.
Flexible drift retardant designed for use with potato blight fungicides said to reduce drift and maximise coverage
A flexible drift retardant, specifically designed for use with blight fungicides, could play an important role in keeping potatoes disease free this spring, according to adjuvant and biostimulant experts, Interagro.
