  1. 21. Effector vector design in the Phytophthora infestans-potato pathosystem

    Master-uppsats, SLU/Dept. of Plant Biology and Forest Genetics (until 131231)

    Författare :Abu Sayeed Tareq; [2012]
    Nyckelord :Phytophthora infestans; potato genome; effectors; potato pathosystem; effector vector design;

    Sammanfattning : The oomycete pathogen Phytophthora infestans is the causal agent of the devastating plant disease late blight on potato. Diverse type of transposons and many gene families are present in the genome which encodes the effector proteins involved in causing the pathogenicity. LÄS MER

  3. 22. Oosporbildning av Phythophthora infestans i potatis och bägarnattskatta

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

    Författare :Oskar Björling; [2012]
    Nyckelord :Potatisbladmögel; Oospor; Phytophtora infestans; Värdväxt; Brunröta;

    Sammanfattning : Potato late blight is one of the most important potato diseases worldwide. The disease is caused by an oomycete called Phytophthora infestans. The host range of P. infestans includes potato (Solanum tuberosum) and hairy nightshade (Solanum physalifolium). LÄS MER

  4. 23. Varying levels of susceptibility to late blight in Ecuador : relation between resistance and the need for fungicide application

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

    Författare :Jenny Knutsson; [2011]
    Nyckelord :Phytophthora infestans; potato; computer simulation; simulation model;

    Sammanfattning : Potato late blight is a devastating disease in potato production all over the world and constitutes the major biological yield limiting factor in Ecuador. The disease is generally controlled chemically and a large proportion of the total potato production cost in Ecuador is due to fungicides. Potato late blight is also controlled by disease escape.

  5. 24. Kan man minska användningen av fungicider med Inducerad resistens? : Försök med BABA mot potatisbladmögel

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

    Författare :Oskar Hansson; [2010]
    Nyckelord :inducerad resistens; potatisbladmögel; fungicider; BABA; Phytophthora infestans;

    Sammanfattning : Potatisbladmögel som orsakas av oomyceten Phytophthora infestans rankas som den mest destruktiva skadegöraren inom jordbruket världen över. Den mest effektiva metoden för att bekämpa potatisbladmögel med idag är en frekvent användning av fungicider. LÄS MER

  7. 25. Raspberry cane midge (Resseliella theobaldi (Barnes)) : biology, control methods and monitoring

    L3-uppsats, SLU/Dept. of Plant Protection Biology

    Författare :Thilda Nilsson; [2008]
    Nyckelord :raspberry cane midge; Resseliella theobaldi; pheromone; control; raspberry; midge blight; monitoring;

    Sammanfattning : Raspberry cane midge is a serious pest of raspberries. The larvae feed in natural splits in the primocanes and these feeding wounds allow entry of infection by several fungi. The complex of larval feeding and fungal infection is termed midge blight. Midge blight leads to poor vigour of second-year canes with fewer fruit-bearing lateral shoots. LÄS MER
