  1. 1. Spray Induced Gene Silencing in Phytophthora infestans : investigating exogenous dsRNA application for the control of potato late blight

    Master-uppsats, SLU/Dept. of Plant Breeding (from 130101)

    Författare :Poorva Sundararajan; [2024]
    Nyckelord :Phytophthora infestans; RNAi; potato late blight; gene silencing; SIGS;

    Sammanfattning : Phytophthora infestans is an oomycete pathogen and the causal agent of late blight disease in potato and tomato. Even today, it causes massive loss to crop and economy worldwide. Current disease control strategies include breeding for resistance and extensive fungicide spray. LÄS MER

  3. 2. Att bespruta eller inte bespruta?- En studie om växtskyddsmedels påverkan på pollinatörer i svenska jordgubbsodlingar

    Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Elin Johansson; [2023]
    Nyckelord :pollinatörer; fungicider; herbicider; insekticider; jordgubbar; växtskyddsmedel; Earth and Environmental Sciences;

    Sammanfattning : This study investigated how pollinators are affected by plant protection products (PPP), what type of PPPs strawberry farmers used and what knowledge they had about these products. To investigate this, a literature review and a survey was conducted. The questionnaire was sent to 70 Swedish strawberry farmers of which 11% participated in the study. LÄS MER

  4. 3. Foliar fungal communities of naturally regenerated and nursery-produced Scots pine (Pinus sylvestris) seedlings

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Sara López Fernández; [2023]
    Nyckelord :Endophytes; high-throughput sequencing; foliar fungi; forest nursery; fungal community; fungal pathogens; metabarcoding; mycobiome; Pinus sylvestris; pine seedlings; Scots pine needles;

    Sammanfattning : Endophytic fungal communities living in leaves of trees can have a significant impact on their hosts,showing both beneficial and detrimental effects. Some mutualistic fungal species protect the host against pathogens or herbivores, while pathogenic species can increase the vulnerability of the host against biotic and abiotic stresses. LÄS MER

  5. 4. Investigating fungicide resistance of Alternaria solani, a Solanaceae pathogen, on potato crops in south-eastern Sweden and its relationship with soil

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

    Författare :Emma Lefèvre; [2023]
    Nyckelord :Alternaria solani; fungicide resistance; Fluopyram; mycelial growth; type of soil; soil conditions;

    Sammanfattning : Alternaria solani is a worldwide present fungus that can cause a lot of damage such as early blight in potato crops. Potato can suffer a lot of yield losses because of this pathogen, and the main method used today to fight against it, is the application of fungicides. LÄS MER

  7. 5. Växtnäringens betydelse i förebyggandet av svampsjukdomar

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

    Författare :Julia Eriksson; [2023]
    Nyckelord :Fungicider; gödning; gödslingsstrategi; IPM; växtskydd;

    Sammanfattning : Svampsjukdomar kan orsaka stora problem och skördeförluster inom växtodlingen. Därför används fungicider för att bekämpa svamparna och skydda grödan. Fungicider kan dock vara skadliga för andra organismer och därmed störa ekosystem och den biologiska mångfalden. LÄS MER
