Alternativer til glyfosat i korn og grasmark

Tørresen, Kirsten; Brandsæter, Lars Olav; Netland, Jan; Berge, Therese W.; Ringselle, Björn; Strand, Einar (NIBIO Rapport;, Research report, 2018)

Glyfosat er det mest brukte plantevernmidlet i Norge og på verdensbasis. Det har i de siste årene vært diskutert om dette ugrasmiddelet skulle få fornyet godkjenning. I 2017 ble glyfosat godkjent for fem nye år til 2022. ...

CombCut : selective control of docks (Rumex spp.) in grassland

Beachell, Andreas Myki (Master thesis, 2018)

Rumex spp. are known as troublesome weed species in grassland, both in pastures and on arable land, reducing both grass yield and forage quality. A novel machine called CombCut (Just Common Sense AB) has been designed to ...

Control of Elymus repens by rhizome fragmentation and repeated mowing in a newly established white clover sward

Bergkvist, G.; Ringselle, B.; Magnuski, E.; Mangerud, Kjell; Brandsæter, Lars Olav (Journal article; Peer reviewed, 2017)

Control of perennial weeds, such as Elymus repens, generally requires herbicides or intensive tillage. Alternative methods, such as mowing and competition from subsidiary crops, provide less efficient control. Fragmenting ...

Control of perennial weeds in spring cereals through stubble cultivation and mouldboard ploughing during autumn or spring

Brandsæter, Lars Olav; Mangerud, Kjell; Helgheim, Marit; Berge, Therese W. (Journal article; Peer reviewed, 2017)

Creeping perennial weeds are of major concern in organically grown cereals. In the present study, the effects of different timing of mouldboard ploughing with or without a preceding stubble cultivation period, on weeds and ...

Control of rush (Juncus spp.) : an expanding weed in grassland areas in Western Norway

Kaczmarek-Derda, Wiktoria (PhD Thesis;2016:83, Doctoral thesis, 2016)

The perennial weeds soft rush (Juncus effusus L.) and compact rush (J. conglomeratus L.) have become an increasing problem in grassland in Western Norway and other European countries with high annual precipitation. Their ...
