  1. 16. Reducerade fungiciddoser vid bekämpning av potatismögel - vilka blir följderna?

    Magister-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Magnus Jönsson; Gabriella Olsson; [2015]
    Nyckelord :potatisbladmögel; Phytophthora infestans; aggressivitet; fungicidtolerans; Inifinito; Ranman Top; Revus Top; potato late blight; aggressiveness; fungicide tolerance;

    Sammanfattning : Potato late blight, caused by the oomycete Phytophthora infestans, is the most devastating crop disease in potato crop globally and annually cost growers 5 billion USD in losses and control measures. Large quantities of fungicides are used for the control of potato late blight in order to avoid yield loss and to limit the risk of tuber blight. LÄS MER

  3. 17. Genotypic and phenotypic variation of Phytopthora infestans on potato in the two Swedish regions Bjäre and Östergötland in 2015

    Master-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Ida Peterson; [2015]
    Nyckelord :potato late blight; mating type; simple sequence repeat markers SSR ; microsatellites; Multiplex PCR; sexual reproduction; asexual reproduction; aggressiveness; tests; population study;

    Sammanfattning : Potato late blight, caused by the oomycete Phytophthora infestans, is a very im-portant disease on potato, and one of the most devastating plant diseases in agri-culture worldwide. Despite the small area of potato in comparison with other cul-tivated crops, 40 % of the total use of fungicides in Sweden is used on potato. LÄS MER

  4. 18. Phycoremediation of pesticides using microalgae

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

    Författare :Embla Ardal; [2014]
    Nyckelord :bioremediation; biosorption; Chlorella vulgaris; fungicides; microalgae; pesticides phycoremediation;

    Sammanfattning : Every year, pesticides are found in surface and ground waters in Sweden. Fungicides are in common usage and applied in high amounts against potato late blight. The present thesis examined the possible removal of four fungicides (metalaxyl, cyprodinil, propamocarb and mandipropamid) from water using the microalgae Chlorella vulgaris. LÄS MER

  5. 19. Effekten av sockerbetsextrakt (SBE) och hormonreglering i sjukdomsutveckling av stjälkbakterios i potatis, Solanum tuberosum, orsakad av Dickeya solani

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

    Författare :Stefan Hultenius; [2014]
    Nyckelord :stjälkbakterios; Dickeya solani; sockerbetsextrakt;

    Sammanfattning : Stjälkbakterios är ett svårbehandlat problem som orsakar ökande skördeförluster av potatis i Sverige och Europa. Sedan 2005 har den nyligen upptäckta patogenen Dickeya solani spridits genom Europa via handel med sättknölar och orsakat ökande ekonomiska förluster. Under kommande år kan D. LÄS MER

  7. 20. Evaluation of Integrated Pest Management (IPM) adoption in potato production using the Sustainable Livelihoods Approach : a qualitative study from central Ecuador

    Master-uppsats, SLU/Dept. of People and Society

    Författare :Fernando Pellegrini; [2013]
    Nyckelord :IPM; Sustainable Livelihoods Approach; potato; pesticides; farmer groups; participation; poverty; livelihood assets; Ecuador;

    Sammanfattning : Potato production and consumption play a big role in the central highlands of Ecuador. Two main biotic constraints hinder the development of potato crops on the field: the Late Blight (Phytophtora infestans) and the Andean potato Weevil (Premnotrypes vorax). LÄS MER
