Download or read book Toxigenic Fusarium Species Identity and Mycotoxicology written by W. F. O. Marasas and published by Penn State University Press. This book was released on 1984 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: The taxonomy of fungi in the genus Fusarium is complex and confusing because of the different taxonomic systems in use in various parts of the world. Taxonomy of the genus is further complicated by its extreme variability in culture and by the fact that Fusarium species mutate and degenerate rapidly in culture. This situation has led to great confusion in the extensive literature on Fusarium mycotoxicoses because the same fungus is known under a variety of different names in different countries. This book, a comparative taxonomic study of Fusarium species reported to be toxigenic in published findings, represents the first serious attempt to clarify the confusion in the taxonomy and nomenclature of toxigenic Fusarium species. It is a catalog of the isolates in the International Toxigenic Fusarium Reference Collection, which is made up of isolates collected from research workers around the world. Information on each isolate includes the correct identification, references to publications in which the isolate is cited, and information on the toxic properties of and mycotoxins reported to be produced by each isolate. The nomenclature used follows the system given in Fusarium Species: An Illustrated Manual for Identification. These two volumes will be useful to anyone interested in the mycotoxins produced by Fusarium species.
Download or read book Diversity and Baseline Fungicide Sensitivity of Fusarium Head Blight in Wheat and Malting Barley written by Joseph A. Cinderella and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fusarium head blight (FHB), primarily caused by Fusarium graminearum, is a top disease of concern to wheat and barley production, contributing to both yield losses and grain contamination across the United States (US). FHB is of particular importance to small grain production in the East Coast and Mid-Atlantic region, with widespread occurrence annually. F. graminearum is well adapted to the climate of the Mid-Atlantic; able to thrive during warm and wet conditions and able to infect wheat, barley, corn, beans, and other small grain crops. For many years, triazole/ demethylation inhibitor (DMI, FRAC Group 3) fungicides were the only group labeled for FHB. In 2019, Miravis Ace (Syngenta, Switzerland), was registered for use in the management of FHB, containing propiconazole (DMI) and pydiflumetofen, a Succinate Dehydrogenase Inhibitor (SDHI, FRAC Group 7). In vitro poison plate mycelial assays were performed on Fusarium isolated from wheat and malting barley to determine baseline sensitivities to pydiflumetofen. Wheat samples were submitted from 16 states and malting barley samples were submitted from three states as part of the United States Wheat and Barley Scab Initiative (USWBSI) National FHB Collection. In total, 177 Fusarium graminearum isolates from wheat were obtained across 2020 (n=98), 2021 (n=65), and from historic isolate collections ranging from 1991-2014 (n=14) with no exposure to pydiflumetofen. The effective concentration to reduce mycelial growth by 50% (EC50) was determined for wheat isolates using potato dextrose agar (PDA) Petri dish assays amended with pydiflumetofen to final concentrations of 0, 0.01, 0.05, 0.25, 1.0, and 5.0 Îơg/mL. Wheat EC50 values ranged from 0.18 to 0.73 Îơg/mL, averaging 0.4 Îơg/mL and 0.37 Îơg/mL, in 2020 and 2021 respectively. The average EC50 value of historic isolates was 0.35 Îơg/mL. Malting barley production has been expanding across the Mid-Atlantic. From 2020-21, malting barley isolates were collected to identify species diversity and screen for fungicide baseline fungicide sensitivity to pydiflumetofen. In the preliminary set of 28 barley isolates, 79% were identified as F. graminearum, 7% F. verticillioides, 7% F. acuminatum, 3.5% F. poae, and 3.5% F. asiaticum. Diversity of Fusarium species recovered from malting barley samples merits continued exploration. In vitro assays were conducted on amended yeast bacto agar (YBA) plates and a subset of isolates were also tested on amended PDA to compare growth. Media plates were amended with pydiflumetofen to final concentrations of 0, 0.01, 0.05, 0.25, 1.0, and 5.0 Îơg/mL. Average EC50 values for barley isolates on YBA were 1.09 Îơg/mL for F. graminearum (n=22), 1.07 Îơg/mL for F. verticillioides (n=2), 1.51 Îơg/mL for F. acuminatum (n=2), 1.09 Îơg/mL for F. poae (n=1), and 1.09 Îơg/mL for F. asiaticum (n=1). Isolates grown on YBA and PDA responded to treatment similarly, with EC50 values of 1.09 and 1.04 Îơg/mL, respectively. YBA-grown isolates experienced more uniform lateral growth and were more amenable to rating than PDA-grown isolates. The established baseline fungicide sensitivity levels in wheat and malting barley will aid fungicide research and allow for monitoring of sensitivity levels in F. graminearum populations in small grain production regions of the United States as SDHI fungicide use expands.

Download or read book Seed Endophytes written by Satish Kumar Verma and published by Springer. This book was released on 2019-04-05 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the importance and roles of seed microbiomes in sustainable agriculture by exploring the diversity of microbes vectored on and within seeds of both cultivated and non-cultivated plants. It provides essential insights into how seeds can be adapted to enhance microbiome vectoring, how damaged seed microbiomes can be assembled again and how seed microbiomes can be conserved. Plant seeds carry not only embryos and nutrients to fuel early seedling growth, but also microbes that modulate development, soil nutrient acquisition, and defense against pathogens and other stressors. Many of these microbes (bacteria and fungi) become endophytic, entering into the tissues of plants, and typically exist within plants without inducing negative effects. Although they have been reported in all plants examined to date, the extent to which plants rely on seed vectored microbiomes to enhance seedling competitiveness and survival is largely unappreciated. How microbes function to increase the fitness of seedlings is also little understood. The book is a unique and important resource for researchers and students in microbial ecology and biotechnology. Further, it appeals to applied academic and industrial agriculturists interested in increasing crop health and yield.

Download or read book Mycotoxins in Plant Disease written by A. Logrieco and published by Springer Science & Business Media. This book was released on 2013-12-01 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is an urgent need to expand our knowledge of both the nature of the toxigenic fungi that are widespread on economically-important plants and the effect of their toxic secondary metabolites on human health. Informa tion about the production of mycotoxins by plant pathogens, particularly by species of Fusarium, Aspergillus and Penicillium, their occurrence in infected plants, as well as their role in the plant-pathogen interaction, for example as virulence/pathogenicity factors, is a pre-requisite for preventing plant disease and hence for reducing the Ievels of mycotoxin contamination. Fusarium infections in cereals and other crops are a particular problern world-wide and recent epidemics on wheat in Europe, the USA and Canada have again focused attention on this problem. Fur thermore, species ofAspergillus and Penicillium and their related mycotoxins, particularly Ochratoxin A, represent another consistent problern on cereals and grapes, especially in Europe where 40% of the global grape crop is grown. The aim of this publication is to gather together specialist updated reviews based on papers originally presented during a Workshop of EU Cost Action 835 entitled 'Agriculturally Important Taxigenie Fungi', held in Rome, 7-8 October 1999 at the Plant Pathology Research Institute. We hope the diversity of the contents will stimulate discussion, encourage the sharing of information and result in cross-fertilization of ideas needed for the solution of the present problems. This special issue will be of particular value to interdisciplinary scientists and especially mycologists, mycotoxicologists, plant pathologists and those concerned about the quality of food and food products.
