ABSTRACT

This paper begins with a survey of recent commodity price developments that highlights the magnitude of this price surge and identifies the rapid rise in wheat prices as a key element. The analysis in this paper focuses on the extent to which domestic markets are insulated from these changes and on the resulting impacts on world prices. An econometric analysis using Error Correction Models finds stable long-term relationships between world wheat prices and most domestic prices of wheat and wheat products, but with considerable variation across countries in the rate of price transmission. A case study of the price shocks during the Covid pandemic and the Ukraine food price crisis finds that price insulation roughly doubled the overall increase in world wheat prices and raised their volatility both during periods of price increase and price decline.

ABSTRACT

Global suffering from COVID-19 has necessitated augmenting the immunity systems of humans through consumption of macro-micro-nutrients and antioxidant-enriched fortified foods. In this article, fortifications of popular bakery products, viz. biscuits, cookies, have been reviewed, encompassing the novel fortifying ingredients and innovative methods employed with an emphasis on the overall enrichment in the final product quality. A few notable features concerning novel fortified biscuit and fortified cookie have been decisively summarized. Wheat flour blended with 40% sesame-cake flour resulted in a fortified biscuit possessing higher protein (16.6%), crude fat (16.95%), and dietary fiber (8.2%) with acceptable sensory characteristics. About 9% toting up of chicken-eggshell dried-powder could result in high Ca content in biscuits with customary changes in texture and sensory properties. A remarkable 5% addition of bee pollen to wheat flour appreciably improved the nutrient compositions (carbohydrate 65.18%, protein 7.32%, and total dietary-fiber 1.47%) along with high polyphenol and antioxidant potentials. Notably, mixing fish fillet protein concentrate with wheat flour could yield enhanced nutritional content (protein 14.63-19.52%, fat 16.2-16.5%), as well as augmented amino acids. Remarkably, wheat flour fortified with fermented jack bean flour resulted in an overall fortified biscuit with substantial carbohydrate, crude protein, fat, fiber, ash, and appreciable macro-micro mineral contents and sensory characteristics. Innovative fortified cookies were made by blending wheat flour or Brewer's spent grain flour with one or more ingredients, e.g. full fat soya, mushroom, cardamom powder, moringa leaves, coconut, sweet potato flour rendering amplified values of nutrients, superior physical properties, increased mineral and flavonoid contents and organoleptic qualities.Copyright © 2023 Bentham Science Publishers.

ABSTRACT

Background: The World Health Organization (WHO) designated SARS-CoV-2 infection as coronavirus disease 2019 (Covid-19).Due to the government implication of Covid-19 specific guideline of using mask, there could be a significant decrease in the allergic rhinitis. Objective(s): Present study aims to analyze the changes in the trends of nasal allergies from hilly regions of Himachal Pradesh following Covid-19 pandemic. Method(s): The prospective data obtained from January 2022 to November 2022 was compared from the retrospective data available between January 2019 to November 2019. Prospectively, a total of 596 patients were included in the study. All these patients underwent Skin prick tests for common allergens. All these patients also underwent testing for total IgE levels in biochemistry lab of the hospital by chemiluminescence method.The results were compared with retrospective dataof 728 age sex match patients. Result(s): A significant difference in the allergen sensitivity was observed. The number of patients who were sensitized during Covid was comparatively less than those during Pre covid period.Dust mite, Cockroach, Peanut and Wheat revealed a non-significant odds ratio indicating that they were not true predictors for sensitization and non-sensitization. Whereas Grass pollen, Mould mix and Pine mix revealed a significant odds ratio. Usage of mask found to have an impact on improvement in symptoms. Majority of the patients who did not use mask had no improvement in symptoms. Majority of the patients had high IgE levels in pre covid period whereas it was normal for majority of them during covid. Conclusion(s): In our study, allergic rhinitis incidence decreased throughout the pandemic period. After pandemic, there was a noticeably decreased level of sensitivity to grass pollen, mould, and pine mix. Use of face masks lead to significant decrease in symptoms of allergic rhinitis.Copyright © 2022, Anka Publishers. All rights reserved.

ABSTRACT

Today, economic shocks, negative effects of climate change, and the crises that directly affect human health, such as the COVID-19 pandemic, have shown that food security is always important for every country, regardless of its development status. With the introduction of the concept of healthy food along with adequate food, people have begun to change the criteria they look for when they eat. The demand for wheat-related products, which constitute the raw material of one of the most basic nutrients for human beings, has changed within this structure. It can be said that einkorn, emmer, and spelt wheats, which are known as the ancestors of wheat, come to the fore more today, especially when the demand for the products produced from wheat landraces is getting to increase. The fact that the products obtained from these wheats, which are important in terms of genetic resources, are healthier and more nutritious than the products obtained from commercial wheats is one of the main reasons for this interest. There are important initiatives in the production and commercialization of hulled wheat-based products in many countries in the world. It is seen that the products obtained from emmer and einkorn wheats are offered to the market, especially in Europe, as well as in countries such as Turkiye and the production is supported by the states, NGOs, and private sector. The products obtained from this type of wheats are finding more and more place day by day in different systems such as geographical indication and organic agriculture. For this reason, wheat landraces are of great importance as a genetic resource, and their sociological and economic aspects need to be evaluated in their conservation and sustainable use. In this study, the socioeconomic evaluation of einkorn wheat has been done and the results of a case study on Iza wheat, an einkorn wheat from Turkiye, have been presented. As a result of the study, it has been shown that economic sustainability is important in the protection and sustainability of this type of wheat, and it needs start-up support at the starting point. When these are provided, it has been revealed that the production of such wheat can become widespread both in organic agriculture and in the geographical indication system, and this type of wheat can be used as a development tool in local economic development by transforming it into value-added products. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.

ABSTRACT

The importance of food supply throughout the world has once again shown its significance in the COVID-19 pandemic period. A continuous food supply is possible with correct agricultural programming. An effective agricultural product programming can only be possible by obtaining precise agricultural data. However, it is very difficult to gather accurate agricultural production statistics from all over the world and confirm their accuracy. In this study, the compatibility of the production statistics of six important agricultural products (wheat, rice, potato, onion, banana, apple) which had been collected from local sources, and had published as opensource by the Food and Agriculture Organization of the United Nations, with Benford's law was examined for the first time. Data for the last two decades are used to ignore the impact of annual fluctuations. The compatibility of theoretically expected and observed data was tested by Chi-square (X2) and Mean Absolute Deviation (MAD) tests. Although inconsistencies were found in some data by examining the numbers in the first, second, and first two digits, in general, the MAD test results gave a mostly concordant result.

ABSTRACT

This article discusses development of technology for obtaining natural nutriceutics in solid form. Currently, a healthy lifestyle, a healthy diet and the body's resistance to external negative factors have become topical issues, especially after the outbreak of the global COVID-19 pandemic. Basically, the prevention and treatment of diseases occurs due to the replenishment of the complex of bioactive substances that the body receives from healthy food. Otherwise, if the tissues and organs do not receive the elements necessary for the normal functioning of the body, then the strength to fight the disease decreases. Here, dietary supplements, that is, nutraceuticals, play an important role, they are consumed with food and are mainly obtained from products of natural origin: vegetable, animal and bacterial.Copyright © 2023, Codon Publications.

ABSTRACT

PurposeThe study aims to evaluate the long- vs short-run relationships between crops' production (output) and crops' significant inputs such as land use, agricultural water use (AWU) and gross irrigated area in India during the period 1981–2018.Design/methodology/approachThe study applied the autoregressive distributed lag (ARDL) bounds testing approach to estimate the co-integration among the variables. The study uses the error correction model (ECM), which integrates the short-run dynamics with the long-run equilibrium.FindingsThe ARDL bounds test of co-integration confirms the strong evidence of the long-run relationship among the variables. Empirical results show the positive and significant relationship of crops' production with land use and gross irrigated area. The statistically significant error correction term (ECT) validates the speed of adjustment of the empirical models in the long-run.Research limitations/implicationsThe study suggests that the decision-makers must understand potential trade-offs between human needs and environmental impacts to ensure food for the growing population in India.Originality/valueFor a clear insight into the impact of climate change on crops' production, the current study incorporates the climate variables such as annual rainfall, maximum temperature and minimum temperature. Further, the study considered agro-chemicals, i.e. fertilizers and pesticides, concerning their negative impacts on increased agricultural production and the environment.

ABSTRACT

See PDF] First reported in Brazil in 1985, wheat blast disease spreads through infected seeds, crop residues and spores that can travel long distances in the air. "Wheat is a staple food for 35 per cent of the world's population, so a disease that threatens pandemic potential could cause serious food security implications,” she told SciDev.Net. "Thanks to the prompt and public release of genomic data by the international scientific community through the OpenWheatBlast initiative, we were able to detect, track, and characterise the fungal lineage responsible for recent wheat blast outbreaks,” said lead author Sergio Latorre Ochoa from University College London.

ABSTRACT

Case report Dust is a known mixture and carrier of multiple allergens and an epidemiologic study demonstrated the presence of peanut proteins in school cafeterias and classrooms, suggesting that schools may play an important role in exposure to environmental food allergens. While inhalation of food allergens is a known trigger of IgE-mediate acute respiratory reaction as rhinitis and wheezing, little is known about persistent allergic asthma and/or rhinitis induced by chronic inhalation of food allergens. Here we report two cases of teenagers with nuts allergy presenting with persistent respiratory symptoms when exposed to closed and dusty environments. The first case concerns a 12-year-old boy allergic to walnut and hazelnut (specific IgE > 100 and 81.70 kU/l, respectively). For some years he has had a persistent mild asthma, frequent nasal occlusion and rhinorrhea, without any allergic sensitization to aeroallergens. Symptoms occurred exclusively during school period when he required maintenance therapy with inhaled and nasal steroids. He was asymptomatic and did not need any treatment during summer. During the lockdown period due to Covid-19 pandemic, he did not attend school for several months and he was able to discontinue inhaled corticosteroid therapy without recurrence of asthma and rhinitis symptoms. Asthma recurred after he returned to school, but with only mild intermittent symptoms, probably thanks to the use of masks and the frequent airing of the classrooms. On a single occasion he experienced nasal occlusion and rhinorrhea after that a parent had eaten hazelnut cream in the same room where he was. The second case deals with a 17-year-old boy with a history of several food allergies (milk, egg, wheat, banana, nuts, hazelnuts) and mild persistent asthma in absence of sensitization to aeroallergens. He successfully underwent oral desensitization for milk, egg and wheat in previous years. Asthma symptoms improved over the years together with progressive development of oral tolerance to food allergens for which oral immunotherapy had been done. On the other hand, he referred persistence of allergic rhinitis especially during the school year and his symptoms got worse in classroom. Exhaled nitric oxide was quite increased with evidence of eosinophils in nasal smears. In-vitro and in-vivo tests only detected food allergens sensitizations, in particolar to walnuts and hazelnuts (specific IgE were 61.00 and 55.50 kU/l respectively). These two clinical cases suggest that food allergens might be causative agents of allergic persistent asthma and/or rhinitis as aeroallergens do.

ABSTRACT

[...]the article closes with policy recommendations to prevent the weaponization of wheat. [...]Russia has recently violated Swedish airspace,8 simulated attacks on Norway,9 jammed GPS systems during NATO exercises,10 and tested new missile systems.11 Russia's quest for melting Arctic fossil fuels is part of an overall plan to leverage the advantages they gain from climate change, a plan that is marked by increased aggression and strategic manipulation of climate-vulnerable regions. [...]as importing countries transition away from fossil fuels, demand for Russian oil and gas will decrease, reducing the overall [End Page 63] revenue for the Russian economy. Countries that fell under the Soviet sphere of influence during the Cold War are less diversified in their energy mixes than those in Western Europe and are highly dependent on Russia.19 For example, in 2015, the stateowned oil and gas company Gazprom increased prices for the Baltic states, Bulgaria, and Poland.20 EU antitrust regulators found that Gazprom was manipulating gas prices in Bulgaria and Poland to force them to participate in additional pipeline projects.21 Such manipulative tactics could indicate future avenues for hybrid warfare, through which Russia combines military strength with economic, resource, technological, or political aggression.22 Russia's use of energy as a form of hybrid warfare can also be seen clearly in Ukraine.

ABSTRACT

Purpose: The Russia–Ukraine war has disrupted the wheat supply worldwide. Given that wheat is one of the most important agri-food products in the world, it is necessary to pay attention to the wheat supply chain during the global crises. The use of resilience strategies is one of the solutions to face the supply chain disruptions. In addition, there is a possibility of multiple crises occurring in global societies simultaneously. Design/methodology/approach: In this research, the resilience strategies of backup suppliers (BS) and inventory pre-prepositioning (IP) were discussed in order to cope with the wheat supply chain disruptions. Furthermore, the p-Robust Scenario-based Stochastic Programming (PRSSP) approach was used to optimize the wheat supply chain under conditions of disruptions from two perspectives, feasibility and optimality. Findings: After implementing the problem of a real case in Iran, the results showed that the use of resilience strategy reduced costs by 9.33%. It was also found that if resilience strategies were used, system's flexibility and decision-making power increased. Besides, the results indicated that if resilience strategies were used and another crisis like the COVID-19 pandemic occurred, supply chain costs would increase less than when resilience strategies were not used. Originality/value: In this study, the design of the wheat supply chain was discussed according to the wheat supply disruptions due to the Russia–Ukraine war and its implementation on a real case. In the following, various resilience strategies were used to cope with the wheat supply chain disruptions. Finally, the effect of the COVID-19 pandemic on the wheat supply chain in the conditions of disruptions caused by the Russia–Ukraine war was investigated. © 2023, Emerald Publishing Limited.

ABSTRACT

Conflicts across the globe affect food security and also have a heavy toll on food safety. Many of the areas affected by conflict are breadbaskets for multiple countries. When the production of staple crops is compromised by diverse conflicts, it becomes necessary to grow them somewhere else to satisfy local, regional, and/or international requirements. However, if that production is done in tropical and subtropical zones, it must be done incorporating strategies to prevent mycotoxin contamination, which has negative health, social, and economic impacts. Otherwise, increased production of susceptible crops in mycotoxin-prone areas may augment the already occurring negative impacts, which are severe in the global south.

ABSTRACT

Introduction: Since 2005, Russia has established a stable position in Egypt's wheat imports, and after 2016, it became the largest global wheat exporter. The shift in Russian grain production has visibly affected wheat export destinations in favor of developing countries. This paper identifies the main determinants of wheat trade in Egypt concerning the primary risks associated with the war in Ukraine. Methods: The paper utilizes time series analysis, index analysis, and an econometric model to define the statistical relationship between the quantity of wheat imported into Egypt and population development, wheat price, and wheat production. Results: Despite increasing wheat production growth rates (1.9% p.a. over 2000–2020) and a growing population (2.01% p.a.), Egypt is unable to reduce its import dependence below 50% of total consumption. Undernourishment in Egypt remains at 5.2%–5.4% of the population. The econometric model shows that variables describing the evolution of production, population, and prices are statistically significant in relation to wheat imports. Egypt's wheat imports continue to increase even with rising prices, which is typical for developing countries. The war in Ukraine and associated commodity price increases have far-reaching implications for Africa's food security and supply systems. Discussion: Egypt's vulnerability to external influences, such as climate change, migration, rising commodity prices, and population growth, exacerbates the situation. Most African countries, including Egypt, struggle with the economic and social impacts of the COVID-19 pandemic. They also face rising food and energy prices, conflicts between the world's largest food producers, and increasing poverty rates. The research findings confirm that Egypt is among the highly vulnerable countries due to the war in Ukraine and the disruption of agricultural supply chains.

ABSTRACT

The production of wheat, as one of the elementary and strategic nutrition crops, in North Macedonia is insufficient and cannot meet the national demands, which results with negative trade balance with import of 74,937 tons of wheat valued at 17.9 million EUR. The main goal of this paper is to analyse the influence of international markets on wheat prices in the Republic of North Macedonia. Data on the purchase price of wheat have been analysed using statistical methods and models from December 2009 to December 2021. A total of 145 monthly time series with data on the purchase price of wheat for Macedonia, the EU, Bulgaria, Romania and Serbia have been analysed and compared. The Pearson correlation coefficient shows a relatively high relationship and mutual dependence of purchase prices in Macedonia, compared to prices in the EU, Bulgaria, Romania and Serbia (over 65%). The purchase prices of wheat in Macedonia have the highest relationship and mutual dependence with the price movement in Serbia (0.78), and the lowest with the price movement in the EU (0.66). The estimated lag length of the autoregressive process (AIC, BIC, FPE and HQIC tests), on average shows 2 lags (months) later time reaction of the wheat prices in Macedonia with the comparison countries countries. The forecasting model (Granger causality test) shows that time series of wheat prices can be convenient for forecasting wheat prices in Macedonia. As of October 2021, the model clearly shows the impact of food economic crisis and unexpected, immediate rise of wheat prices as result of the post Covid-19 and Ukraine war crisis. This research and analysis model can provide significant information for the wheat price trends, forecasting and markets shock, as management and decision-making tools for producers, traders and processors, but also for the policy makers.

ABSTRACT

Many aphid-borne viruses are important pathogens that affect wheat crops worldwide. An aphid-transmitted closterovirus named wheat yellow leaf virus (WYLV) was found to have infected wheat plants in Japan in the 1970s; however, since then, its viral genome sequence and occurrence in the field have not been investigated. We observed yellowing leaves in the 2018/2019 winter wheat-growing season in an experimental field in Japan where WYLV was detected five decades ago. A virome analysis of those yellow leaf samples lead to the discovery of a closterovirus together with a luteovirus (barley yellow dwarf virus PAV variant IIIa). The complete genomic sequence of this closterovirus, named wheat closterovirus 1 isolate WL19a (WhCV1-WL19a), consisted of 15,452 nucleotides harboring nine open reading frames. Additionally, we identified another WhCV1 isolate, WL20, in a wheat sample from the winter wheat-growing season of 2019/2020. A transmission test indicated that WhCV1-WL20 was able to form typical filamentous particles and transmissible by oat bird-cherry aphid (Rhopalosiphum pad). Sequence and phylogenetic analyses showed that WhCV1 was distantly related to members of the genus Closterovirus (family Closteroviridae), suggesting that the virus represents a novel species in the genus. Furthermore, the characterization of WhCV1-WL19a-derived small RNAs using high-throughput sequencing revealed highly abundant 22-nt-class small RNAs potentially derived from the 3'-terminal end of the WhCV1 negative-strand genomic RNA, indicating that this terminal end of the WhCV1 genome is likely particularly targeted for the synthesis of viral small RNAs in wheat plants. Our results provide further knowledge on closterovirus diversity and pathogenicity and suggest that the impact of WhCV1 on wheat production warrants further investigations.

ABSTRACT

Covid-19 pandemic had limited people's movement despite the demand to remain productive and maintain good health. Therefore, it was necessary to provide foods which are easy to distribute, durable, nutritious, and easily transformable to increase immunity. This research aims to develop a composite flour (TK) formula with optimal proportion of wheat flour (TT), snakehead fish flour (TIG), pumpkin flour (TBuL), and pumpkin seed flour (TBiL) which then enriched with zinc. The resulting TK is expected to be used as an ingredient for nutritious snacks containing high protein and zinc. The research was conducted in four stages, namely the making of each constituent flour, determining the best formulation with the Response Surface Methodology using Central Composite Design model, characterizing the physicochemical properties of TK and making meatballs, biscuits, and unting-unting from the TK. The three products were tested on experimental animals for their metabolic responses. The optimization of the formula resulted in three optimal formulations, namely formula A, B, and C with the proportion of TT:TIG:TBuL:TBiL respectively as follows 55:20:15:10;56.65:20:13.35:10;57.98:20:12.02:10. The most optimal formula of composite flour was formula A with the highest protein (26.12%) and zinc (18.06 mg/kg) content among other formulas. Then, zinc was added into Formula A using microencapsulation, and TK with protein content of 26.74% and zinc of 56.8 mg/kg were obtained. The histopatology observation on experimental animals showed that the three products made from TK did not cause necrosis of the liver or cell infiltration in the kidneys.

ABSTRACT

Orange-fleshed sweet potato (OFSP) and pumpkin fruit are underutilized crops with great potential for the production of high-quality bread with health-enhancing properties. However, the incorporation of nonconventional flour in bread formula may influence the dough and bread quality properties. This study investigated the effect of partial substitution of wheat flour with OFSP (10–50%) and pumpkin flour (10–40%), baking temperature (150–200 °C) and baking time (15–25 min) on the quality properties of the composite dough and bread using response surface methodology (RSM). Dough rheological, bread physical and textural properties were analyzed, modelled and optimized using RSM. Satisfactory regression models were developed for the dough and bread quality attributes (R2 > 0.98). The dough development time, crust redness, hardness, and chewiness values increased while optimum water absorption of dough, specific volume, lightness, springiness, and resilience of bread decreased significantly (p < 0.05) with increasing incorporation of OFSP and pumpkin flour in the bread formula. Additionally, the specific volume, crust redness, crumb hardness, and chewiness of the composite bread increased significantly (p < 0.05) with increasing baking temperature from 150 to 180 °C but reduced at higher baking temperatures (≥ 190 °C). The staling rate declined with increased OFSP and pumpkin flour whereas increasing the baking temperature and time increased the bread staling rate. The optimized formula for the composite bread was 78.5% wheat flour, 11.5% OFSP flour, 10.0% pumpkin flour, and baking conditions of 160 °C for 20 min. The result of the study has potential applications in the bakery industry for the development of functional bread.

ABSTRACT

Egypt faces wheat insecurity due to the limited cropped area of agricultural lands and the limited horizontal expansion disproportionate to the population increase. The issue of food security, crop consumption rates, and self-sufficiency is considered one of the most important problems facing countries that seek to improve sustainable agriculture and economic development to eliminate poverty or hunger. This research aims to use data mining classification techniques and decision tree algorithms to predict the food security status of strategic agricultural crops (e.g., wheat) as an Agro intelligence technique. Also, the outputs and extracted information from the prediction process will help decision-makers to take an appropriate decision to improve the self-sufficiency rate of wheat, especially in epidemic crises and hard times such as COVID-19, political, and economic disturbances. On the other hand, the research investigates the patterns of wheat production and consumption for the Egyptian population from 2005 to 2020. This research presents a methodology to predict the food security status of strategic agricultural crops through the case study of wheat in Egypt. The proposed model predicts the food security status of wheat with an accuracy of 92.3% to determine the self-sufficiency ratio of wheat in Egypt during the years from 2015 to 2020. Also, it identifies the factors affecting the food security status of wheat in Egypt, their impact on determining and improving the food security state and its rate of self-sufficiency. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

ABSTRACT

Various kinds of field crops growing on two commercial farms in the Whitehorse area of the southern Yukon Territory were surveyed for diseases in summer 2020 by staff of the Agriculture Branch of the Government of Yukon. They included barley, wheat, canola, beets, broccoli, cabbage, carrots, potatoes and turnips. Fields were visited one or more times during July and August. The incidence and severity of diseases were visually assessed on a crop-by-crop basis and samples were collected for laboratory analysis of the pathogens present, if any. Both infectious and non-infectious diseases were present on most crops. The infectious diseases were caused by various species of plant pathogenic bacteria and fungi that were common on these crops growing in other areas of Canada. INTRODUCTION AND METHODS: The 2020 field crop disease survey is believed to be the first organized study of its kind on agricultural crops in the Territory. In his book, "An Annotated Index of Plant Diseases in Canada . . . ", I.L. Conners lists over 300 records of plant diseases on trees, shrubs, herbs and grasses in the Yukon that were published by individuals who were surveying forests and native vegetation mainly for federal government departments, universities and other agencies (Conners 1967). The objectives of the 2020 survey were: (1) to determine the kinds and levels of diseases on selected Yukon crops, (2) to identify the major pathogen species attacking Yukon crops, and (3) to use the results to plan future surveillance activities aimed at helping producers to improve their current disease management programs. All of the fields included in the 2020 survey were situated on two commercial farms, which were designated as Farm #1 and #2, in the Whitehorse area in the southern Yukon (Fig. 1). The crops surveyed included cereals (barley and wheat), oilseeds (canola) and vegetables (beets, broccoli, cabbage, carrots, potatoes and turnips). Fields were visited one or more times in the mid- to late growing season (July/August) at a time when damage from diseases was most noticeable. Symptoms were visually assessed on a crop-by-crop basis by determining their incidence and severity. Incidence was represented by the percentage of plants, leaves, heads, kernels, etc., damaged in the target crop, while severity was estimated to be the proportion of the leaf, fruit, head, root/canopy area, etc., affected by a specific disease as follows: Proportion of the canopy affected based on a 0-4 rating scale, where: 0 = no disease symptoms, 1 = 1-10% of the crop canopy showing symptoms;2 = 11-25% showing symptoms, 3 = 26- 50% showing symptoms, and 4 = > 50% showing symptoms. Photographs of affected plants were taken and sent to plant pathologists across Western Canada for their opinions on causation. Where possible, representative samples of plants with disease symptoms were packaged and sent to the Alberta Plant Health Lab (APHL) in Edmonton, AB for diagnostic analyses. Background information, such as the general cultural practices and cropping history, was obtained from the producers wherever possible. GPS coordinates were obtained for each field to enable future mapping Cereals: Individual fields of barley (11 ha) and wheat (30 ha) located at Farm #1 were surveyed. The barley was a two-row forage cultivar 'CDC Maverick', while the wheat was an unspecified cultivar of Canada Prairie Spring (CPS) Wheat. Plant samples were taken along a W-shaped transect for a total of five sampling points for the barley field (< 20 ha) and ten sampling points for the wheat field (> 20 ha). The first visit, which occurred on July 30, involved visual inspection and destructive sampling wherein plants were collected and removed from the field for a detailed disease assessment at a lab space in Whitehorse. There, the roots were rinsed off and the plants were examined for disease symptoms. The second visit to these fields, which occurred on August 27, only involved visual examination of the standing crop. Oilseeds: A single 40 ha field of Polish canola (cv. 'Synergy') was examined o
