Most species of Cercospora are known only from their morphological characters in vivo. Although the genus contains more than 5 000 names, very few cultures and associated DNA sequence data are available. In this study, 360 Cercospora isolates, obtained from 161 host species, 49 host families and 39 countries, were used to compile a molecular phylogeny. Partial sequences were derived from the internal transcribed spacer regions and intervening 5.8S nrRNA, actin, calmodulin, histone H3 and translation elongation factor 1-alpha genes.

Corresponding author: [email protected] Abstract Morphological and phylogenetic data are used to revise the genus Torrendiella. The type species, described from Europe, is retained within the Rutstroemiaceae. However, Torrendiella species reported from Australasia, southern South America and China were found to be phylogenetically distinct and have been recombined in the newly proposed genus Hymenotorrendiel- la. The Hymenotorrendiella species are distinguished morphologically from Rutstroemia in having a Hymenoscyphus-type rather than Sclerotinia-type ascus apex. Zoellneria, linked taxonomically to Torrendiella in the past, is genetically distinct and a synonym of Chaetomella. Keywords: ascus apex, phylogeny, taxonomy, Hymenoscyphus, Rutstroemiaceae, Sclerotiniaceae, Zoellneria, Chaetomella Introduction Torrendiella was described by Boudier and Torrend (1911), based on T. ciliata Boudier in Boudier and Torrend (1911: 133), a species reported from leaves, and more rarely twigs, of Rubus, Quercus and Laurus from Spain, Portugal and the United Kingdom (Graddon 1979; Spooner 1987; Galán et al.

  • EVALUATION of ORGANIC INPUTS for REDUCING DOLLAR SPOT DISEASE on COOL-SEASON TURFGRASSES Cody James Be
    ABSTRACT Title of Thesis: EVALUATION OF ORGANIC INPUTS FOR REDUCING DOLLAR SPOT DISEASE ON COOL-SEASON TURFGRASSES Cody James Beckley, Master of Science, 2018 Thesis Directed By: Assistant Professor, Dr. Joseph A. Roberts Plant Science and Landscape Architecture Lolium perenne, Poa annua, and Agrostis stolonifera are turfgrass species commonly grown on golf course fairways; however, they are susceptible to dollar spot (Clarireedia spp.). Field studies were conduction to assess: 1) the effects of organic fertilizer treatments and fungicide programs on dollar spot severity; and 2) the impact of organic amendments on dollar spot severity and residual fungicide efficacy. Alternating applications of organic and conventional fungicides reduced seasonal dollar spot severity to the same degree as conventional fungicides. Dollar spot was more severe in Lolium perenne and Poa annua treated with organic fungicides. On A. stolonifera, organic biosolids compost, biochar, and vermicompost amendments suppressed dollar spot to the same degree as conventional fertilizer in year one of the trial, while dollar spot was more severe on A. stolonifera fertilized with organic biosolids compost in year two. Fertilizer treatments had no effect on residual fungicide efficacy on A. stolonifera.

Mycosphere 10(1), 310–489, Doi 10.5943/mycosphere/10/1/7 Abstract Leotiomycetes is regarded as the inoperculate class of discomycetes within the phylum Ascomycota. Taxa are mainly characterized by asci with a simple pore blueing in Melzer’s reagent, although some taxa have lost this character. The monophyly of this class has been verified in several recent molecular studies. However, circumscription of the orders, families and generic level delimitation are still unsettled. This paper provides a modified backbone tree for the class Leotiomycetes based on phylogenetic analysis of combined ITS, LSU, SSU, TEF, and RPB2 loci. In the phylogenetic analysis, Leotiomycetes separates into 19 clades, which can be recognized as orders and order-level clades.

  • Integrated Management of Dollar Spot Disease of Creeping Bentgrass Using Soil Conditioners
    Integrated Management of Dollar Spot Disease of Creeping Bentgrass Using Soil Conditioners by Eslin Duygu Oztur A Thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Master of Science in Plant Agriculture Guelph, Ontario, Canada © Eslin Duygu Oztur, December, 2020 ABSTRACT INTEGRATED MANAGEMENT OF DOLLAR SPOT DISEASE OF CREEPING BENTGRASS USING SOIL CONDITIONERS Eslin Duygu Oztur Advisor: University of Guelph, 2020 Dr. Katerina Serlemitsos Jordan Dollar spot, caused by the fungus Clarireedia jacksonii, can lead to considerable damage to creeping bentgrass (Agrostis stolonifera L.) on golf course greens. This one-year study assessed management strategies that integrated soil conditioners (fish emulsion, fish hydrolysate, worm castings, and spent mushroom compost) with a rolling treatment to reduce dollar spot severity. None of the soil conditioners reduced dollar spot in the greenhouse or field studies, nor was there any improvement in turf color, clippings, root dry weight or tissue N content. The rolling treatment had a significant effect on turf color and reduced dollar spot severity at one location and only when disease pressure was high. The results indicated that the use of soil conditioners would not be a recommended practice for dollar spot when disease pressure is high but rolling could be included as a management practice to suppress dollar spot. DEDICATION I dedicate this thesis to my beloved mother Aysegul Kivanc, whose profound love, support and encouragement made it possible for me to complete this work. I admire the effort and sacrifice you made for my career in supporting my study abroad. You gave me the strength to make it through another day.

Nematodes are belongs to animal kingdom, they are triploblastic, unsegmented, bilateral symmetrical, pseudocoelomateandhaving well developed reproductive, nervous, excretoryand digestive system where as the circulatory and respiratory systems are absent but govern by the pseudocoelomic fluid. Plant Nematology: Nematology is a science deals with the study of morphology, taxonomy, classification, biology, symptomatology and management of {plant pathogenic} nematode (PPN). The word nematode is made up of two Greek words, Nema means thread like and eidos means form. The words Nematodes is derived from Greek words ‘Nema+oides’ meaning „Thread + form‟(thread like organism ) therefore, they also called threadworms. They are also known as roundworms because nematode body tubular is shape. The movement (serpentine) of nematodes like eel (marine fish), so also called them eelworm in U.K. and Nema in U.S.A. Roundworms by Zoologist Nematodes are a diverse group of organisms, which are found in many different environments. Approximately 50% of known nematode species are marine, 25% are free-living species found in soil or freshwater, 15% are parasites of animals, and 10% of known nematode species are parasites of plants (see figure at left). The study of nematodes has traditionally been viewed as three separate disciplines: (1) Helminthology dealing with the study of nematodes and other worms parasitic in vertebrates (mainly those of importance to human and veterinary medicine).

    Recovery Plan for Rathayibacter Poisoning caused by Rathayibacter toxicus (syn. Clavibacter toxicus) Updated March 2015 (Replaces February 2010 Version) Contents Page Executive Summary 2 Contributors and Reviewers 5 I. Introduction 5 II. Disease Development and Symptoms 8 III. Plant Infection, Spread of the Bacterium, and Animal Poisoning 11 IV. Monitoring and Detection 12 V. Response 13 VI. USDA Pathogen Permits 14 VII. Economic Impact and Compensation 15 VIII. Mitigation and Disease Management 15 IX. Infrastructure and Experts 16 X. Research, Extension, and Education Needs 17 References 20 Web Resources 25 Appendices 26 This recovery plan is one of several disease-specific documents produced as part of the National Plant Disease Recovery System (NPDRS) called for in Homeland Security Presidential Directive Number 9 (HSPD-9). The purpose of the NPDRS is to ensure that the tools, infrastructure, communication networks, and capacity required to minimize the impact of high consequence plant disease outbreaks are available so that an adequate level of crop production is maintained. Each disease-specific plan is intended to provide a brief primer on the disease, assess the status of critical recovery components, and identify disease management research, extension, and education needs. These documents are not intended to be stand-alone documents that address all of the many and varied aspects of plant disease outbreaks and all of the decisions that must be made and actions taken to achieve effective response and recovery. They are, however, documents that will help the USDA to further guide efforts toward plant disease recovery. Cite this document as: Murray, T.D., I. Agarkova, S.
