  1. 11. Detection of Sclerotinia sclerotiorum using qPCR assay and comparison between three qPCR systems to check sensitivity

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Neeraj Patil; [2021]
    Nyckelord :Sclerotinia sclerotiorum; Stem rot disease; fungi; oilseed rape; plant pathogen; absolute quantification; real-time PCR; qPCR; detection; PCR sensitivity;

    Sammanfattning : Sclerotinia sclerotiorum is a pathogenic fungus that infects around 400 species of host    plants. Stem rot disease caused by this fungus is economically disastrous for Brassica napus cultivators in Sweden. Due to the lack of disease resistant cultivars, disease management has been solely dependent on fungicide application. LÄS MER

  3. 12. Partners in crime – How cabbage seed weevil assists brassica pod midge in damaging pods of winter oilseed rape in fields in Southern Sweden : how is insect abundance related to crop damage?

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Sarah Heithausen; [2020]
    Nyckelord :monitoring; Ceutorhynchus obstrictus; Dasineura brassica; Brassica napus; Integrated Pest Management; economic threshold; pan trap; sticky trap;

    Sammanfattning : The brassica pod midge (Dasineura brassicae) has emerged as an important pest causing problems in Winter Oilseed Rape (WOSR) (Brassica napus ssp. napus) production in Southern Sweden during recent years. Adult female D. brassicae oviposit into WOSR pods. LÄS MER

  4. 13. The role of terpenes produced by Brassica napus in interactions with Verticillium longisporum

    Master-uppsats, SLU/Department of Plant Biology (from 140101)

    Författare :Alessandra Ruffino; [2020]
    Nyckelord :Verticillium longisporum; terpenes; Brassica napus; Arabidopsis thaliana;

    Sammanfattning : Verticillium longisporum is responsible for severe yield losses, especially of oilseed rape (Brassica napus). Rapeseed is the third most important source of vegetable oil worldwide. The need to increase rapeseed oil yield is not only because is a source of healthy vegetable oil but also because it is used as a biodiesel. LÄS MER

  5. 14. Effects of within-field and landscape factors on Dasineura brassicae in winter oilseed rape cultivations in Skåne, southern Sweden : a field survey with a special approach to pesticide-free control zones

    Master-uppsats, SLU/Dept. of Plant Protection Biology

    Författare :Emma Johansson; [2019]
    Nyckelord :Dasineura brassicae; brassica pod midge; Ceutorhynchus obstrictus; cabbage seedpod weevil; winter oilseed rape; rapeseed crop damages; pesticide-free control zones; withinfield factors; landscape factors;

    Sammanfattning : Winter oilseed rape (Brassica napus) is the most common oilseed crop grown in the province of Skåne in southern Sweden, where this study was performed. B. napus is often associated with various insect pests. This study regards two of these; the cabbage seed weevil (Ceutorhynchus obstrictus) and the brassica pod midge (Dasineura brassicae). LÄS MER

  7. 15. Landscape and within-field factors affecting the damages of the brassica pod midge (Dasineura brassicae) in Swedish winter oilseed rape cultivation

    Master-uppsats, SLU/Dept. of Plant Protection Biology

    Författare :Axel Rösvik; [2019]
    Nyckelord :landscape ecology; Dasineura brassicae; Ceutorhynchus obstrictus; Brassica napus; winter oilseed rap;

    Sammanfattning : The brassica pod midge (Dasineura brassicae) has been a serious upcoming problem in Swedish oilseed cultivation during recent years. This small dipteran utilized pods damaged by its facilitator, the cabbage seed weevil (Ceutorynchus obstrictus), to be able to oviposit. The larvae of D. LÄS MER
