A. Jamalaisen juhlajulkaisu jubilee issue in honour of Professor E. A. jumalainen HELSINKI 1972 k) Eino Armas Jamalainen syntyi Hietamäessä Inkerinmaalla 17. heinä- kuuta 1902. Siirryttyään Suomeen 1919 hän sai päästötodistuksen Kolp- panan opettajaseminaarista (Helsinki) 1920, suoritti ylioppilastutkinnon 1923, maatalous- ja metsätieteiden kandidaatin tutkinnon 1929, agrono- mitutkinnon 1930 ja maatalous- ja metsätieteiden lisensiaatin tutkinnon 1935 saaden samana vuonna myös maatalous- ja metsätieteiden tohtorin arvon. Jamalaisen elämänuran valintaan samoin kuin hänen toimintaansakin on varmaan merkittävästi vaikuttanut hänen opettajansa ja useiden vuosien aikana myös esimiehensä, Helsingin yliopiston kasvibiologian ja kasvipato- logian ylimääräinen professori J. I. Liro. Tämän kansainvälistä kuului- suutta saavuttaneen, harvinaisen monipuolisen biologian tutkijan moni- vuotisena apulaisena ja matkakumppanina Jamalainen omaksui kyvyn tarkkailla ympärillään luonnon tapahtumia monipuolisesti, ennen muuta kuitenkin kasvipatologina. Useiden muiden maataloustutkijan uralle sittemmin antautuneiden tavoin Jamalainen aloitti uransa sijoittumalla jo opiskeluaikanaan työskentele- mään laboratorioapulaisena silloiseen Maatalouskoelaitokseen. Sen kasvi- tautiosastolla hänelle tarjoutui sitten heti kandidaatin tutkinnon suoritet- tuaan ylimääräisen assistentin toimi. Vuosina 1938-43 hän toimi saman osaston ensimmäisenä assistenttina sekä vuonna 1944 yliassistenttina ja ni- mitettiin samana vuonna mainitun osaston johtajaksi ja professoriksi, josta virasta siirtyi täysinpalvelleena eläkkeelle vuonna 1969. Näin Jamalaisen toiminta kasvipatologian ja kasvinsuojelun alalla Maatalouskoelaitoksessa ja sittemmin Maatalouden tutkimuskeskuksessa jatkui kaikkiaan 40 vuo- den ajan. Vaikka Jamalaisen tutkimustyössä on selvästi havaittavissa sellaiset pää- kohteet kuin boorin puutteen aiheuttamat kasvitaudit, viljojen siementen peittaus, Fusarium-sienien taksonomia ja kasvien talvehtimisongelina, ulot- tuvat hänen tutkimuksensa huomattavasti laajemmalle alalle ja nimen- omaan sen mukaan, mikä ongelma kulloinkin on käytännön viljelyssä tul- lut esille. Vuonna 1935 valmistunut väitöskirjatyö "Tutkimuksia lantun ruskotau- dista" oli ensimmäisiä kasvipatologian kannalta tehtyjä selvityksiä boorin ja yleensäkin hivenravinteiden puutteen aiheuttamista fysiogcenisista kas- vitaudeista. Tämän jälkeen Jamalainen osoitti boorin puutteesta aiheutu- viksi myös omenan kuoppataudin ja juurikkaiden sydän- ja kuivamädän. Viljojen pei ttausmenetelmän merkityksen selvittämisen ja sen tunnetuksi tekemisen Jamalainen sai erikoistehtäväkseen, kun hänet määrättiin 1933 kasvitautiosaston ja Maatalousseurojen Keskusliiton tekemän yhteistyöso- 279 pimuksen perusteella mainitun liiton "nokikonsulentiksi" 6 kk:n ajaksi. Viljojen peittausmenetelmän kehittämisen ja sen yleistämisen hyväksi hän on sittemminkin tehnyt jatkuvasti paljon työtä, josta ovat osoituksena asiaa käsittelevät useat tutkimukset sekä artikkelit ammattilehdissä. Myko- logian alalla Jamalainen on saavuttanut kansainvälistä arvonantoa kah- dellakin tutkimussektorilla. Perehdyttyään 1937 Saksassa tohtori Wollen- weberin johdolla Fusarium-sienten tutkimusmenetelmiin hän ryhtyi selvit- tämään näiden sienien esiintymistä ja merkitystä Suomessa. Tulokset jul- kaistiin 1943 ja 1944 kolmena vihkona "Ober die Fusarien Finnlands" I, Ilja III. Toisena prof. Jamalaisen mykologisen tutkimuksen laajana koh- teena ovat olleet syysviljoja ja nurmiheiniä tuhoavat talvituhosienet eli Fusarium nivale, Typhula ishikariensis, Typhula incarnata sekä Sclerotinia borealis. Myös muiden talvehtivien kasvien bioottisia ja abioottisia talvehtimiseen vaikuttavia tekijöitä samoin kuin talvituhosienien suoranaisen torjunnan mahdollisuuksia kvintotseeni-valmisteilla on selvitetty Jamalaisen johdolla. Sipulin viljelyn edistämiseen tähtäävää tutkimusta suoritettiin hänen joh- dollaan 1949 lähtien varsin intensiivisesti useiden vuosien ajan, ja seurauk- sena olikin sipulin viljelyn huomattava edistyminen maassamme. jamalainen on tutkimustoiminnassaan kaiken aikaa pitäytynyt hyvin lä- hellä käytäntöä. Sitä silmällä pitäen hän on pyrkinyt tutustumaan kasvi- tautiongelmiin ja vallitseviin olosuhteisiin mahdollisimman läheisesti juuri siellä, missä ongelmia on esiintynyt. Jokaiselle tutkijalle, jolla on ollut tilaisuus seurata Jamalaista tutkimusmatkoilla eri tahoille maatamme niin puutarhoissa kuin pelloilla, on jäänyt erityisesti mieleen se välitön help- pous, millä hän on keskustellut viljelijöiden kanssa ja huomaamattomasti johtanut puheen haluamaansa suuntaan eli tavallisesti erilaisten kasvi- tautiongelmien pohtimiseen. Jamalainen on 40 vuoden aikana jakanut opaskirjasin, kirjoituksin ja esi- telmin runsaasti tietoja viljelijöille ja neuvontahenkilöstölle. Nämä käy- täntöä välittömästi palvelemaan tarkoitetut esitykset ovat olleet niin laa- dittuja, että jokaisen on ollut helppo saada niitä tarvitsemansa tiedot. Jamalaisen julkaisutoiminta on runsas ja monipuolinen käsittäen tähän mennessä kaikkiaan 367 tieteellistä tai neuvonnallista julkaisua, artikkelia tai opaskirjasta. Tämän niteen sivuilla 373-379 on luettelo professori Ja- malaisen tärkeimmistä julkaisuista. Varsinaisen virkansa ohella Jamalainen on osallistunut myös kasvipato- logian opetustyöhön Helsingin yliopistossa. Hän ohjasi ylioppilaiden kas- vinsuoj eluharj oituksia 1930 — 43, luennoi dosenttina kasvinsuoj elus ta 1943 —71 sekä hoiti kasvibiologian ja kasvipatologian professorin virkaa 1943 —45 ja 1964-65. Uuden tutkijapolven kehittämiseen hän on osallis- tunut myös siten, että hänen johtajakautenaan on kasvitautiosastolla suo- ritettu useita niin mittavia tutkimuksia, että ne on voitu hyväksyä väitös- kirjoina (Annikki Linnasalmi 1952, J. E. Hårdh 1953, Jaakko Mukula 1957, Aarre Ylimäki 1967, Eeva Tapio 1970 ja Esko Seppänen 1971). 280 Jamalainen on ollut vastaväittäjänä kahta kotimaista mykologian alan väitöskirjaa sekä asiantuntijana seitsemää ulkomaista väitöskirjaa tarkas- tettaess a . jamalaisen osallistuminen kasvipatologien ja kasvinsuojelualan tutkijoi- den kansainväliseen yhteistyöhön on ollut maallemme merkittävän arvo- kasta. Yhteyksien solmimista ovat edistäneet suuresti hänen lukuisat mat- kansa ulkomaille Kansainvälisen yhteistyön kehittämiseen kasvinsuojelun alalla on Jamalaisella ollut tilaisuus osallistua oltuaan vuosina 1961-68 Suomen edustajana EPPO:n (European and Mediterranean Plant Protec- tion Organization) vuosikokouksissa. Skandinaavisessa yhteistyössä hän on ollut mukana mm. PMY:n IV jaoston puheenjohtajana 1948-50, Suo- men osaston johtokunnan jäsenenä 1961-65 sekä osallistumalla aktiivisesti yhdistyksen kokouksiin ja sen työryhmien työskentelyyn. Jamalaisen asiantuntemusta on käytetty hyväksi lukuisissa komiteoissa, toimikunnissa ja työryhmissä, joista mainittakoon vain kasvinsuojeluainei- den tarkastuksen lainsäädäntöä aikaansaamaan asetettu komitea 1948-49, koetoimintakomitea 1953-55, kokonaispalkkakomitea 1955-56, kasvin- suojelutoimikunta 1945-46 ja valtion maatalous-metsätieteellinen toimi- kunta 1965-67. Valtion siementarkastuslaitoksen toimintaan hän on vai- kuttanut merkittävästi ollessaan sen johtokunnan jäsenenä 1942-67 sekä varapuheenjohtajana 1958-61 ja puheenjohtajana 1962-67. Varsin olennaisen puolen Jamalaisen toiminnassa on muodostanut hänen työnsä eräiden julkaisujen toimittamisessa joko toimituskunnan jäsenenä tai aktiivisena toimittajana. Erityisesti on mainittava hänen pitkäaikainen toimintansa Maataloustieteellisen Aikakauskirjan toimitussihteerinä (1948 —72) ja päätoimittajana (1958-72) sekä Annales Agriculturae Fenniae -aikakauskirjan toimituskunnan jäsenenä 1962-68, josta ajasta kolme vii- meistä vuotta päätoimittajana. Jamalaisen neljäkymmentä vuotta jatkunut tutkimustyö maamme pelto- ja puutarhaviljelysten suojaamiseksi kasvitautien tuhoilta on tuonut hyviä tuloksia. Hän on ollut uranuurtaja kasvinsuojelualan tarkastus- ja neuvon- tatyön kehittämisessä maassamme. Eläkeiän ja siten myös eroamisiän saa- vuttaminen ei Jamalaisen kohdalla ole suinkaan merkinnyt tutkimustyön päättymistä. Kiinnostus kasvien talvehtimisongelmaan on saanut hänet viime vuosina paneutumaan yhä syvemmälle abioottisten tekijöiden sel- vittelyyn. 1VIaatalouden tutkimuskeskus ja kasvitautien tutkimuslaitos pyytävät tämän julkaisun muodossa esittää professori Jamalaiselle sydämelliset kiitoksensa hänen suorittamastaan suuriarvoisesta työstä maatalouden ja puutarha- talouden hyväksi. Tikkurilassa 17. kesäkuuta 1972 Aarre Ylimäki 281 The Agricultural Research Centre is dedicating this issue to Professor E. A. Jamalainen in recognition of his life-work for the advancement of plant pathology and plant protection.

These new rust fungi records bring to 70 the number of Puccinia species reported on Poaceae from Pakistan. Puccinia brachypodii var. poae-nemoralis and P. poarum are also reported for the first time from Fairy Meadows. Key words — Anthoxanthum odoratum, graminicolous rust, Hunza Introduction This paper continues our study of graminicolous rust fungi from Pakistan. Previously, about 100 species of graminicolous rust fungi including 68 taxa of Puccinia have been reported from Pakistan (Afshan et al. 2010, 2011a,b). During a 2007 survey of the rust flora of Fairy Meadows, four members of Poaceae infected with rust fungi were collected. Among these, Puccinia brachypodii var. major on Poa attenuata and P. substriata var. indica on Pennisetum orientale represent new records for Pakistan, while P. brachypodii var. poae-nemoralis on Anthoxanthum odoratum and P. poarum on Poa pratensis are additions to the rust flora of Fairy Meadows. Anthoxanthum odoratum represents a new host for rust fungi from Pakistan.

Aspects of the morp­ hology and ontogeny of spores and sari, which were previously disputed, have been clarified. Monokaryotic hyphae grow more densely in the intercellular spaces of Tussilago leaves than the dikaryotic intercellular hyphae on Poa. Although ultrastructurally sbnilar, monokaryotic hyphae differ from dikaryotic hyphae in their interaction with host cell walls, often growing embedded in wall material which may project into the host cells. The frequency of penetration of Poa mesophyll cells by haustoria of the dikaryon is greater than that of Tussilago cells by the relatively undifferentiated intracellular hyphae of the monokaryon. Intracellular hyphae differ from haustoria in their irregular growth, septation, lack of a neck-band or markedly constricted neck, the deposition of host wall-like material in the external matrix bounded by the invaginated host plasmalemma and in the association of callose reactions \vith intracellular hyphae and adjacent parts of host walls.

Synonyms: Cineraria farfara Bernh., Farfara radiata Gilib., Tussilago alpestris Hegetschw., Tussilago umbertina Borbás Common Name: European coltsfoot, coltsfoot, bullsfoot, coughwort, butterbur, horsehoof, foalswort, fieldhove, English tobacco, hallfoot Family: Asteraceae Legal Status: Proposed as a Class B noxious weed for 2018, to be designated for control throughout Washington, except for in Grant, Lincoln, Adams, Benton, and Franklin counties. Images: left, blooming flowerheads of Tussilago farfara, image by Caleb Slemmons, National Ecological Observatory Network, Bugwood.org; center, leaves of T. farfara growing with ferns, grasses and other groundcover species; right, mature seedheads of T. farfara before seeds have been dispersed, center and right images by Leslie J. Mehrhoff, University of Connecticut, Bugwood.org. Description and Variation: The common name of Tussilago farfara, coltsfoot, refers to the outline of the basal leaf being that of a colt’s footprint. Overall habit: Tussilago farfara is a rhizomatous perennial, growing up to 19.7 inches (50 cm tall), which can form extensive colonies. Plants first send up flowering stems in the spring, each with a single yellow flowerhead. Just before or after flowers have formed seeds, basal leaves on long petioles grow from the rhizomes, with somewhat roundish leaf blades that are more or less white-woolly on the undersides. Roots: Plants have long creeping, white scaly rhizomes (Griffiths 1994, Chen and Nordenstam 2011). Rhizomes are branching and have fibrous roots (Barkley 2006). They are also brittle and can break easily (Pfeiffer et al.

  • Typhula Blight Paul Koch, UW-Plant Pathology and PJ Liesch, UW Insect Diagnostic Lab
    XHT1270 Provided to you by: Typhula Blight Paul Koch, UW-Plant Pathology and PJ Liesch, UW Insect Diagnostic Lab What is Typhula blight? Typhula blight, also known as gray or speckled snow mold, is a fungal disease affecting all cool season turf grasses (e.g., Kentucky bluegrass, creeping bentgrass, tall fescue, fine fescue, perennial ryegrass) grown in areas with prolonged snow cover. These grasses are widely used in residential lawns and golf courses in Wisconsin and elsewhere in the Midwest. What does Typhula blight look like? Typhula blight initially appears as roughly circular patches of bleached or straw-colored turf that can be up to two to three feet in diameter. When the disease is severe, patches can merge to form larger, irregularly-shaped bleached areas. Affected turf is often matted and can have a water-soaked appearance. At the edges of patches, masses of grayish-white fungal threads (called a mycelium) may form. In 1 3 addition, tiny ( /64 to /16 inch diameter) reddish-brown or black fungal survival Typhula blight causes circular patches of structures (called sclerotia) may be bleached turf that often merge to form larger, irregularly-shaped bleached areas. present. Typhula blight looks very similar to Microdochium patch/pink snow mold (see University of Wisconsin Garden Facts XHT1145, Microdochium Patch), but the Microdochium patch fungus does not produce sclerotia. Where does Typhula blight come from? Typhula blight is caused by two closely related fungi Typhula incarnata and Typhula ishikariensis. In general, T. incarnata is more common in the southern half of Wisconsin while T. ishikariensis is more common in the northern half of the state.

  • Snow Molds of Turfgrasses, RPD No
    report on RPD No. 404 PLANT July 1997 DEPARTMENT OF CROP SCIENCES DISEASE UNIVERSITY OF ILLINOIS AT URBANA-CHAMPAIGN SNOW MOLDS OF TURFGRASSES Snow molds are cold tolerant fungi that grow at freezing or near freezing temperatures. Snow molds can damage turfgrasses from late fall to spring and at snow melt or during cold, drizzly periods when snow is absent. It causes roots, stems, and leaves to rot when temperatures range from 25° to 60°F (-3° to 15°C). When the grass surface dries out and the weather warms, snow mold fungi cease to attack; however, infection can reappear in the area year after year. Snow molds are favored by excessive early fall applications of fast release nitrogenous fertilizers, Figure 1. Gray snow mold on a home lawn (courtesy R. Alden excessive shade, a thatch greater than 3/4 inch Miller). thick, or mulches of straw, leaves, synthetics, and other moisture-holding debris on the turf. Disease is most serious when air movement and soil drainage are poor and the grass stays wet for long periods, e.g., where snow is deposited in drifts or piles. All turfgrasses grown in the Midwest are sus- ceptible to one or more snow mold fungi. They include Kentucky and annual bluegrasses, fescues, bentgrasses, ryegrasses, bermudagrass, and zoysiagrasses with bentgrasses often more severely damaged than coarser turfgrasses. Figure 2.

  • Activated Resistance of Bentgrass Cultivars to Microdochium Nivale Under Predicted Climate Change Conditions
    Activated Resistance of Bentgrass Cultivars to Microdochium nivale under Predicted Climate Change Conditions by Sara Marie Stricker A Thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Masters of Science in Environmental Science Guelph, Ontario, Canada © Sara Marie Stricker, September, 2017 ABSTRACT ACTIVATED RESISTANCE OF BENTGRASS CULTIVARS TO MICRODOCHIUM NIVALE UNDER PREDICTED CLIMATE CHANGE CONDITIONS Sara Marie Stricker Advisor: University of Guelph, 2017 Professor Dr. Tom Hsiang The potential impact of predicted climate change on Microdochium nivale, which causes Microdochium patch on turfgrasses was investigated. Turfgrasses exposed to temperature fluctuations exhibited increased yellowing caused by M. nivale compared to a constant lower temperature incubation. The effect of increased CO2 (from 400 ppm to 800 ppm) on M. nivale hyphal growth, percent yellowing, and biochemical response was assessed for Agrostis spp. and Poa annua cultivars. The efficacy of the resistance activator, Civitas + Harmonizer, was assessed under conditions of increased CO2, two temperatures, and field conditions. Civitas + Harmonizer often decreased disease symptoms, and suppression varied by cultivar and environmental conditions. Elevated CO2 did not affect the growth of M. nivale, although evidence from growth room trials suggests it may decrease Microdochium patch disease severity in the future. However, the interactive effects of temperature, snow cover conditions, and moisture availability in the field under future conditions is unknown. ACKNOWLEDGEMENTS First and foremost, I would like to thank my advisor Dr. Tom Hsiang for welcoming me back into his lab and for his guidance, patience, and wry witticisms that kept me going. I am also very grateful for the opportunities I have had to participate in conferences and educational experiences throughout my time as a master’s student.

  • Snow Mold on Turfgrass Introduction Winter Diseases of Turfgrasses Are Often Associated with Melting Snow Or Cold, Wet Periods
    CORNELL COOPERATIVE EXTENSION OF ONEIDA COUNTY 121 Second Street Oriskany, NY 13424-9799 (315) 736-3394 or (315) 337-2531 FAX: (315) 736-2580 Snow Mold on Turfgrass Introduction Winter diseases of turfgrasses are often associated with melting snow or cold, wet periods. Bluegrasses (Poa sp.), fescues (Festuca sp.), and ryegrasses (Lolium sp.) may be attacked, but bentgrasses (Agrostis sp.) are most sus- ceptible. Two diseases, Gray Snow Mold (Typhula blight) and Pink Snow Mold, are common in New York and may occur singly or side-by-side. Since different fungicides may be used to control each of these diseases, it is necessary to distinguish between them. Symptoms Gray snow mold (Typhula blight) is caused by Typhula incarnata and related species. It is a true snow mold and appears as roughly circular bleached patches up to 60 cm in diameter (Figure 1). Soon after the snow melts, the infected grass may be matted and surrounded by a white to gray halo of fluffy fun- gal growth. Examination of the diseased plants reveals tiny tan or brown pea-like structures (sclerotia) on or imbedded in infected leaves. The severity of the dis- ease will vary. It is particularly severe when turf has been subjected to a pro- longed, deep, compacted snow cover. Although the disease is unsightly, it rarely kills the grass. Figure 1: Infected spots on turf. Disease Cycle The disease cycle for this fungus is nearly opposite that of most others. This fungus produces sclerotia (resting structures) to help it survive the summer months. In late fall when conditions are favorable, these sclerotia may produce mycelium or basidiocarps (Figure 2) that produce spores.

  • Tarset and Greystead Biological Records
    Tarset and Greystead Biological Records published by the Tarset Archive Group 2015 Foreword Tarset Archive Group is delighted to be able to present this consolidation of biological records held, for easy reference by anyone interested in our part of Northumberland. It is a parallel publication to the Archaeological and Historical Sites Atlas we first published in 2006, and the more recent Gazeteer which both augments the Atlas and catalogues each site in greater detail. Both sets of data are also being mapped onto GIS. We would like to thank everyone who has helped with and supported this project - in particular Neville Geddes, Planning and Environment manager, North England Forestry Commission, for his invaluable advice and generous guidance with the GIS mapping, as well as for giving us information about the archaeological sites in the forested areas for our Atlas revisions; Northumberland National Park and Tarset 2050 CIC for their all-important funding support, and of course Bill Burlton, who after years of sharing his expertise on our wildflower and tree projects and validating our work, agreed to take this commission and pull everything together, obtaining the use of ERIC’s data from which to select the records relevant to Tarset and Greystead. Even as we write we are aware that new records are being collected and sites confirmed, and that it is in the nature of these publications that they are out of date by the time you read them. But there is also value in taking snapshots of what is known at a particular point in time, without which we have no way of measuring change or recognising the hugely rich biodiversity of where we are fortunate enough to live.

    Plant Disease Diagnostic Clinic ol Cornell University Plant Pathology and - • College of Agriculture and Life Sciences Plant‐Microbe Biology Section 334 Plant Science Building Ithaca, NY 14853‐5904 Gray Snow Mold on Turfgrass: Typhula spp. Introduction Symptoms and Signs Winter diseases of turfgrasses are often associated Gray snow mold (Typhula blight) is caused by with melting snow or cold, wet periods. Bluegrasses Typhula incarnata and related species. It is a true (Poa spp.), fescues (Festuca spp.), and ryegrasses snow mold and appears as roughly circular bleached (Lolium spp.) may be attacked, but bentgrasses patches up to 60 cm in diameter (Fig. 1). Soon after (Agrostis spp.) are most susceptible. Two diseases, the snow melts, the infected grass may be matted and Gray Snow Mold (Typhula blight) and Pink Snow surrounded by a white to gray halo of fufy fungal Mold, are common in New York, and may occur growth. Examination of the diseased plants reveals singly or side-by-side. Since diferent fungicides may tiny tan or brown pea-like structures (sclerotia) on, or be used to control each of these diseases, it is imbedded in, infected leaves. Te severity of the necessary to distinguish between them. disease will vary. It may be particularly severe when turf has been subjected to a prolonged, deep, compacted snow cover. Although the disease is unsightly, it rarely kills the grass. Figure 2: Clavula of sporocarps in close-up view of infected turf. Disease Cycle Te disease cycle for this fungus is nearly opposite Figure 1: Infected spots on turf. that of most others.
