  1. 1. Hur påverkas uppkomsten av renkavle (Alopecurus myosuroides Huds.) av olika bearbetningsstrategier under hösten? : How is the emergence of black-grass (Alopecurus myosuroides Huds.) influenced by different mechanical strategies during the autumn?

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Izabelle Strandqvist; Agust Persson; [2023]
    Keywords : Renkavle; black-grass; åtgärder mot renkavle; mekanisk ogräsbekämpning; fröbanksanalys; soil seed bank; fröbank;

    Abstract : Syftet med detta examensarbete var att undersöka hur uppkomsten av renkavle samt fröbanken påverkades av olika mekaniska jordbearbetningsmetoder under hösten. I den experimentella delen av examensarbetet utvärderades ett redan befintligt försök som genomfördes under hösten 2022 med olika bearbetningsmetoder för att bekämpa renkavle. READ MORE

  3. 2. Carabids as weed seed control agent : impact of soil cultivation on carabid weed seed regulation

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Ellen Dahlgren; [2023]
    Keywords : weed seed predation; weed seed bank regulation; weed seed predation strength; seed predation strength; carabid beetles; tillage; piecewise structural equation model;

    Abstract : As weed seed predators, carabid beetles can regulate the weed seed bank within agricultural fields. Little is anyhow known about how weed seed bank regulation by carabids is affected by different tillage treatments with decreasing intensity, why this was here examined. READ MORE

  5. 4. Ogräskontroll : i odlingssystem utan glyfosat och med liten användning av herbicider och jordbearbetning

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Albin Hidén; [2020]
    Keywords : alleopati; conservation agriculture; glyfosat; glyfosatförbud; herbicid; herbicidresistens; jordbearbetning; mellangrödor; ogräs; ogräskonkurrens; ogräskontroll; reducerad jordbearbetning; växtföljd;

    Abstract : Ogräs har oftast större betydelse för en grödas avkastning än både skadeinsekter och växtsjukdomar. Ogräskontroll sker i huvudsak med användning av herbicider och jordbearbetning. En överanvändning av selektiva herbicider under lång tid har lett till att ogräspopulationer har utvecklat resistens mot dessa. READ MORE

  6. 5. Weed Seed Bank Assessment in Organic Crop Rotations : Comparing the weed suppression effect from intercropping field pea and spring barley, with sole cropping and black fallow

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Harald Helgesson; [2019]
    Keywords : weed management; crop competitive ability; black fallow; organic crop production; Pisum sativum; Hordeum vulgare; Avena sativa;

    Abstract : In the urge to mitigate the negative impact of weeds, like reduced yields, both agricultural and horticultural production have heavily relied on herbicides for weed control. This has led to vast environmental problems like human health risks and negative impact on biodiversity. READ MORE
