  1. 11. Fungicide resistance against fluopyram in Alternaria solani

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

    Författare :Felicia Ekdahl; [2022]
    Nyckelord :Fluopyram; Alternaria solani; early blight; potato; Solanum tuberusum;

    Sammanfattning : Early blight in potato production can be devastating and to minimize crop damage the use of fungicides has been the key. New fungicides called the SDHIs have been used against the early blight pathogen, Alternaria Solani in potato fields to reduce yield losses. LÄS MER

  3. 12. Assessing the effect of Fusarium graminearum inoculation on the root structure of Swedish winter wheat cultivars (Triticum aestivum

    Master-uppsats, SLU/Dept. of Crop Production Ecology

    Författare :Fayez Altabbaa; [2022]
    Nyckelord :Fusarium graminearum; conidium suspension; hypha agar plug; root architecture traits; root cellar structure traits; shoot traits; genotypes;

    Sammanfattning : Several diseases attack the wheat crop and reduce the yield, such as root disease, which causes a tremendous loss in wheat production. Root rot has a variety of causal agents, such as nematodes, viruses, and bacteria, but the most common pathogens causing wheat root rot are oomycetes and fungi. LÄS MER

  4. 13. Isolation, protocol optimization and screening of genotypes against net blotch and scald of barley in controlled condition

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

    Författare :Rishap Dhakal; [2022]
    Nyckelord :barley; net blotch; scald; isolation; seedling resistance;

    Sammanfattning : Net blotch and scald are two economically important diseases of barley, causing significant losses in yield in Nordic and Baltic states (NBS) countries and in Sweden. Identification and deployment of resistant cultivars is the most effective method for controlling both the diseases. LÄS MER

  5. 14. Cover crops for plant protection : Cover crops for control of root pathogenic Plasmodiophora brassicae and the root parasitic nematodes Pratylenchus penetransand Meloidogyne hapla

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

    Författare :Izabella Lundborg; [2022]
    Nyckelord :Clubroot disease; plant parasitic nematodes; Lupinus angustifolius; Avena strigosa; Phacelia tanacetifolia; Lolium perenne; Solanum lycopersicum; Brassica napus;

    Sammanfattning : Root pathogens and parasites are an increasing problem in agricultural and horticultural production. The soil borne pathogen Plasmodiophora brassicae is one of the major pathogens in oilseed rape production and the plant parasitic nematodes (PPNs), Pratylenchus penetrans and Meloidogyne hapla infest important crops such as carrot, potato and strawberry.

  7. 15. Effects of plant-fungal interactions on volatile emission of Hordeum vulgare and aphid preference

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Bina Johansson; [2022]
    Nyckelord :volatile organic compounds; chemical communication; Trichoderma atroviride; Fusarium graminearum; Rhopalosiphum padi; biological control;

    Sammanfattning : Barley is one of the most economically important cultivated crops in the world. However, barley is a host for many insect pests and plant pathogenic fungi which is a threat to the production. Rhopalosiphum padi is an economically important insect pest that leads to large economical losses in agricultural crops such as barley. LÄS MER
