  1. 1. Stump treatment against Heterobasidion root rot in practical forestry : how well does it work?

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Anna Nilsson; [2020]
    Nyckelord :Heterobasidion; Phlebiopsis gigantea; stump treatment efficacy; Rotstop®S Gel;

    Sammanfattning : The effect of Phlebiopsis gigantea on root and butt rot causing fungus Heterobasidion spp. was investigated in fifteen stands of Norway spruce (Picea abies) in southern Sweden. The stumps were mechanically treated immediately after felling and only stumps with no sign of decay were sampled for the study. LÄS MER

  3. 2. Efficacy of practical stump treatment in Latvia

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Uvis Skola; [2019]
    Nyckelord :Norway spruce Picea abies ; Heterobasidion; Phlebiopsis gigantea; Rotstop; urea; covered stumps;

    Sammanfattning : Root and butt rot caused by Heterobasidion spp. result in severe economic losses in Norway spruce forests of the northern hemisphere. Stump treatment using biological or chemical control agents are amongst the most effective solutions of limiting introduction of Heterobasidion spp. after tree felling. LÄS MER

  4. 3. Efficacy of Phlebiopsis gigantea treatment on spore infections of Heterobasidion spp. on Larix X eurolepis

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Erik Ek; [2011]
    Nyckelord :Root rot; hybrid larch; Larix x eurolepis; stump treatment Phlebiopsis gigantea;

    Sammanfattning : The effectiveness of Phlebiopsis gigantea to prevent spore infections from Heterobasidionannosum and Heterobasidion parviporum on hybrid larch stumps were investigated in fivestands in southern Sweden. All sites are former forest land and the age of the trees wasbetween 9 and 13 years. LÄS MER

  5. 4. Precommercial thinning stumps' susceptibility to Heterobasidion spp. : a comparison between high and low Norway spruce and birch stumps : a measuring of the efficacy of Phlebiopsis gigantea stump treatment

    Magister-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Rebecka Mc Carthy; [2011]
    Nyckelord :pre-commercial thinning stumps; heterobasidion spp; phlebiopsis gigantea stump treatment;

    Sammanfattning : Each year, Heterobasidion spp. is a major cause of economic losses to forestry in the northern hemisphere, including Sweden. New results indicate that pre‐commercial thinnings could be at risk for Heterobasidion spp. infections. LÄS MER

  7. 5. Efficacy of different concentrations of Rotstop® and RotstopS and imperfect cover of RotstopS against Heterobasidion spp. infections on Norway spruce stumps

    L3-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Evgeny Sidorov; [2005]
    Nyckelord :Rotstop; spruce;

    Sammanfattning : The effectiveness of treatment with two Phlebiopsis gigantea based preparations (Rotstop® and RotstopS) in different concentrations against the root and butt rot causing fungus Heterobasidion annosum s.l. on Norway spruce (Picea abies) thinning stumps in southern Sweden was compared.
