Summary

The experimental thesis consists of a greenhouse trial where cover crops are evaluated in a bioassays with respective parasitic or pathogenic organisms. Cover crop species Lolium perenne, Avena strigosa and Lupinus angustifolius is evaluated in its ability to counteract plant parasitic nematode species Pratylenchus penetrans and Meloidogyne hapla and the protist pathogen Plasmodiophora brassicae. P. brassicae is a complex pathogen affecting Brassica crops worldwide causing severe crop loss. There is no direct control method available, the difficulties of control are related to the long lived resting spores that can survive up to 20 years in the soil without a host. Plant parasitic nematodes P. penetrans and M. hapla are both concerning upcoming pests in global agriculture. Both M. hapla and P. penetrans have a wide host range causing severe damage in several important agricultural crops there among carrot, sugar beet, tomato and strawberry. There are limited control options available for these organisms, they are either non efficient or non sustainable leaving a great need and demand for sustainable action methods. The specific cover crops have previously been observed in decreasing nematode densities and P. brassicae resting spore amount in soil and thereby has the potential to be used as a promising tool for controlling them.

There has been no doubt that my future would be in horticulture. Since I was a child I have been engaged in plant protection. I was the “protector” of our garden making sure aphids didn't get away with harming my mothers plants and protecting bees from getting slammed. Since then I have evolved my knowledge in my studies at Säbyholms agriculture gymnasium, University of Bologna Faculty Agriculture and at SLU- Alnarp. My main interest is plant protection within means to work against a future sustainable food production. I'm especially interested in conservation biological control, plant and pathogen interactions, functional biodiversity in arebleland and of course cover crops. Also technological development in these areas intrest me, I believe it will play an important role in efficient and extended usage in the future. My best professional qualities are that I am driven, flexible, curious, calm and have very good discipline. During my free time, I prefer to engage in outdoor activities, cook, cultivate and take care of my bee hives. If you want to know more about my project or me, feel free to contact me at:
