    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Axel Jonsson; Erik Rumler; [2020]
    Nyckelord :Skogssällskapet; rotticka; Rotstop®;

    Sammanfattning : En stor del av den areal Skogssällskapet förvaltar i Lettland utgörs av åkerplanterad gran, vilken riskerar att drabbas av rötsvampen rotticka (Heterobasidion spp.) i samband med kommande skötselåtgärder. LÄS MER

  3. 2. Vattenlogistik vid stubbehandling i slutavverkning

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Henrik Ekström; [2014]
    Nyckelord :arbetssätt; rotröta; tidsstudie;

    Sammanfattning : Water logistics has long been a problem in order to effectively carry out stump treatment in both thinning and final felling. It is important that the stump treatment‐ equipment is configured as well as a sufficient amount of water is carried out on the harvester to get a cost‐ effective treatment. LÄS MER

  4. 3. Stump treatment with the root rot antagonist phlebiopsis gigantea : - sensitivity of P. gigantea spores to high pressure stress; - reduced water consumption for stump treatment

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Martin Pettersson; [2013]
    Nyckelord :Stump treatment; Heterobasidion annosum; Heterobasidion parviporum; Phlebiopsis gigantea; Picea abies; Rotstop; pressure stress; water consumption;

    Sammanfattning : Stump treatment today requires large quantities of clean water mixed with the protective product Rotstop, to fully cover the stump surface. In order to reduce the water consumption without reducing the coverage of the stump surface, the pressure in the stump treatment device can be increased. Therefore, the Phlebiopsis gigantea (Fr.) Jül. LÄS MER

  5. 4. Stubbehandling med pergamentsvamp och urea mot sporinfektioner av rotticka i bestånd av hybridlärk

    Magister-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Henrik Pålsson; [2009]
    Nyckelord :Rotröta; Heterobasidium; Hybridlärk ; Stubbehandling; Pergamentsvamp; Urea;

    Sammanfattning : Root rot is a big hurter and a huge economic problem for the Swedish and European forestry. The severest hurter is Heterobasidion annosum (Fr.) Bref and it occurs as two different species in Sweden. Commonly referred to as the P-type (Heterobasidion annosum s. LÄS MER

  7. 5. Presence of Heterobasidion annosum and the need for stump treatment in monocultures of Scots pine in southern Sweden

    L3-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Eglė Petrylaitė; [2004]
    Nyckelord :heterobasidion annosum; stump treatment; monocultures of Scots pine; pinus sylvestris L.;

    Sammanfattning : The incidence of Heterobasidion spp. in the roots of Scots pine (Pinus sylvestris L.) was investigated in fifteen monocultures of Scots pine in southern Sweden. On the basis of crown condition, all trees were divided into four classes from healthy to dead trees on a number of sample plots at each site. LÄS MER
