  1. 1. Analyses of circular DNA molecules in the leafhopper Psammotettix alienus for identification of viruses and plasmids

    Master-uppsats, SLU/Dept. Of Plant Biology

    Författare :Jeremiah Sigalla; [2019]
    Nyckelord :blue dwarf disease; leafhopper; phylogenetic analysis; psammotettix alienus; rolling circle amplification; wheat blue dwarf phytoplasma; wheat dwarf disease; wheat dwarf virus;

    Sammanfattning : Microorganisms often depend on vectors for transmission. A single vector may carry different species of microorganisms such as fungi, bacteria and viruses. In Sweden, leafhoppers of the species Psammotettix alienus are known as a vector of wheat dwarf virus, but they may be carriers of other microorganisms as well. LÄS MER

  3. 2. Efficacy of silver nanoparticles against rice blast disease and farmers perception about its management in Bangladesh

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

    Författare :Rumana Akter; [2019]
    Nyckelord :rice; blast disease; management; mycelial growth; silver nanoparticles;

    Sammanfattning : Rice blast caused by Magnaporthe grisea is one of the major and recurrent threats for sustainable rice production in Bangladesh. To mitigate this problem, the current study was aimed to investigate the efficacy of silver nanoparticles against rice blast disease and farmers’ perception or knowledge about rice blast disease management in Bangladesh.

  4. 3. Invasive Phytophthora species affecting broadleaved tree species in urban and landscape settings in Southern Sweden

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Mimmi Blomquist; [2017]
    Nyckelord :fagus sylvatica; phytophthora; forest; pathogen; invasive; P.gonapodyides; pildammsparken; Sweden;

    Sammanfattning : Phytophthora translates to ‘plant destroyer’ and are fungal-like, hemibiotrophic plant pathogens. Phytophthora was discovered in the mid 19th century, as the causal agent of the widespread collapse of potato crops throughout Europe. LÄS MER

  5. 4. Detection of cassava brown streak viruses in coastal Tanzania

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

    Författare :Annica Forslund; [2014]
    Nyckelord :Cassava brown streak virus; CBSV; Ugandan cassava brown streak virus; UCBSV; Cassava; Tanzania;

    Sammanfattning : Cassava brown streak disease (CBSD) is a factor which can decrease cassava production up to 70%. Cassava is an important crop, especially in sub-Saharan Africa for small-scale farms, as it is a staple food with tolerance to local conditions such as draught. LÄS MER

  7. 5. Emerging infectious diseases : a model of disease transmission dynamics at the wildlife-livestock interface in Uganda

    Master-uppsats, SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Författare :Fredrik Backlund; [2013]
    Nyckelord :emerging infectious disease; African swine fever; wildlife; disease transmission; genotype;

    Sammanfattning : Emerging infectious diseases are a recurring threat to both human and animal health. Understanding the multiple causes behind the emergence of new diseases is key to the prevention of new and potentially devastating outbreaks. LÄS MER
